Internet privacy involves the right or mandate of personal privacy concerning the storing, repurposing, provision to third parties, and displaying of information pertaining to oneself via Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing.
Privacy can entail either personally identifiable information (PII) or non-PII information such as a site visitor's behaviour on a website. PII refers to any information that can be used to identify an individual. For example, age and physical address alone could identify who an individual is without explicitly disclosing their name, as these two factors are unique enough to identify a specific person typically. Other forms of PII may soon include GPS tracking data used by apps, as the daily commute and routine information can be enough to identify an individual.
It has been suggested that the "appeal of online services is to broadcast personal information on purpose." On the other hand, in his essay "The Value of Privacy", security expert Bruce Schneier says, "Privacy protects us from abuses by those in power, even if we're doing nothing wrong at the time of surveillance."
Levels of privacy
Internet and digital privacy are viewed differently from traditional expectations of privacy. Internet privacy is primarily concerned with protecting user information. Law Professor Jerry Kang explains that the term privacy expresses space, decision, and information. In terms of space, individuals have an expectation that their physical spaces (e.g. homes, cars) not be intruded. Privacy within the realm of decision is best illustrated by the landmark case Roe v. Wade. Lastly, information privacy is in regards to the collection of user information from a variety of sources, which produces great discussion.
In the United States, the 1997 Information Infrastructure Task Force (IITF) created under President Clinton defined information privacy as "an individual's claim to control the terms under which personal information — information identifiable to the individual — is acquired, disclosed, and used." At the end of the 1990s, with the rise of the internet, it became clear that governments, companies, and other organisations would need to abide by new rules to protect individuals' privacy. With the rise of the internet and mobile networks internet privacy is a daily concern for users.
People with only a casual concern for Internet privacy need not achieve total anonymity. Internet users may protect their privacy through controlled disclosure of personal information. The revelation of IP addresses, non-personally-identifiable profiling, and similar information might become acceptable trade-offs for the convenience that users could otherwise lose using the workarounds needed to suppress such details rigorously. On the other hand, some people desire much stronger privacy. In that case, they may try to achieve Internet anonymity to ensure privacy — use of the Internet without giving any third parties the ability to link the Internet activities to personally-identifiable information of the Internet user. In order to keep their information private, people need to be careful with what they submit to and look at online. When filling out forms and buying merchandise, information is tracked and because it was not private, some companies send Internet users spam and advertising on similar products.
There are also several governmental organizations that protect an individual's privacy and anonymity on the Internet, to a point. In an article presented by the FTC, in October 2011, a number of pointers were brought to attention that helps an individual internet user avoid possible identity theft and other cyber-attacks. Preventing or limiting the usage of Social Security numbers online, being wary and respectful of emails including spam messages, being mindful of personal financial details, creating and managing strong passwords, and intelligent web-browsing behaviors are recommended, among others.
Posting things on the Internet can be harmful or expose people to malicious attacks. Some information posted on the Internet persists for decades, depending on the terms of service, and privacy policies of particular services offered online. This can include comments written on blogs, pictures, and websites, such as Facebook and Twitter. It is absorbed into cyberspace and once it is posted, anyone can potentially find it and access it. Some employers may research a potential employee by searching online for the details of their online behaviors, possibly affecting the outcome of the success of the candidate.
Risks to Internet privacy
Companies are hired to track which websites people visit and then use the information, for instance by sending advertising based on one's web browsing history. There are many ways in which people can divulge their personal information, for instance by use of "social media" and by sending bank and credit card information to various websites. Moreover, directly observed behaviour, such as browsing logs, search queries, or contents of the Facebook profile can be automatically processed to infer potentially more intrusive details about an individual, such as sexual orientation, political and religious views, race, substance use, intelligence, and personality.
Those concerned about Internet privacy often cite a number of privacy risks — events that can compromise privacy — which may be encountered through online activities. These range from the gathering of statistics on users to more malicious acts such as the spreading of spyware and the exploitation of various forms of bugs (software faults).
Several social networking websites try to protect the personal information of their subscribers, as well as provide a warning through a privacy and terms agreement. On Facebook, for example, privacy settings are available to all registered users: they can block certain individuals from seeing their profile, they can choose their "friends", and they can limit who has access to their pictures and videos. Privacy settings are also available on other social networking websites such as Google Plus and Twitter. The user can apply such settings when providing personal information on the Internet. The Electronic Frontier Foundation has created a set of guides so that users may more easily use these privacy settings and Zebra Crossing: an easy-to-use digital safety checklist is a volunteer-maintained online resource.
In late 2007 Facebook launched the Beacon program in which user rental records were released to the public for friends to see. Many people were enraged by this breach of privacy, and the Lane v. Facebook, Inc. case ensued.
Children and adolescents often use the Internet (including social media) in ways that risk their privacy: a cause for growing concern among parents. Young people also may not realize that all their information and browsing can and may be tracked while visiting a particular site and that it is up to them to protect their own privacy. They must be informed about all these risks. For example, on Twitter, threats include shortened links that may lead to potentially harmful websites or content. Email threats include email scams and attachments that persuade users to install malware and disclose personal information. On Torrent sites, threats include malware hiding in video, music, and software downloads. When using a smartphone, threats include geolocation, meaning that one's phone can detect where one's location and post it online for all to see. Users can protect themselves by updating virus protection, using security settings, downloading patches, installing a firewall, screening email, shutting down spyware, controlling cookies, using encryption, fending off browser hijackers, and blocking pop-ups.
However most people have little idea how to go about doing these things. Many businesses hire professionals to take care of these issues, but most individuals can only do their best to educate themselves.
In 1998, the Federal Trade Commission in the US considered the lack of privacy for children on the internet and created the Children Online Privacy Protection Act (COPPA). COPPA limits the options which gather information from children and created warning labels if potential harmful information or content was presented. In 2000, the Children's Internet Protection Act (CIPA) was developed to implement Internet safety policies. Policies required taking technology protection measures that can filter or block children's Internet access to pictures that are harmful to them. Schools and libraries need to follow these requirements in order to receive discounts from E-rate program. These laws, awareness campaigns, parental and adult supervision strategies, and Internet filters can all help to make the Internet safer for children around the world.
The privacy concerns of Internet users pose a serious challenge (Dunkan, 1996; Till, 1997). Due to the advancement in technology, access to the internet has become easier to use from any device at any time. However, the increase of access from multiple sources increases the amount of access points for an attack. In an online survey, approximately seven out of ten individuals responded that what worries them most is their privacy over the Internet, rather than over the mail or phone. Internet privacy is slowly but surely becoming a threat, as a person's personal data may slip into the wrong hands if passed around through the Web.
Internet protocol (IP) addresses
There is ambiguity about how private IP addresses are. The Court of Justice of the European Union has ruled they need to be treated as personally identifiable information if the website tracking them, or a third party like a service provider, knows the name or street address of the IP address holder, which would be true for static IP addresses, not for dynamic addresses. California regulations say IP addresses need to be treated as personal information if the business itself, not a third party, can link them to name and street address. An Alberta court ruled that police can obtain the IP addresses and the names and addresses associated with them, without a search warrant; the Calgary, Alberta, police found IP addresses which initiated online crimes, and the service provider gave police the names and addresses associated with those IP addresses.
In the past, websites have not generally made the user explicitly aware of the storing of cookies, however tracking cookies and especially third-party tracking cookies are commonly used as ways to compile long-term records of individuals' browsing histories — a privacy concern that prompted European and US lawmakers to take action in 2011. Cookies can also have implications for computer forensics. In past years, most computer users were not completely aware of cookies, but users have become conscious of possible detrimental effects of Internet cookies: a recent study done has shown that 58% of users have deleted cookies from their computer at least once, and that 39% of users delete cookies from their computer every month. Since cookies are advertisers' main way of targeting potential customers, and some customers are deleting cookies, some advertisers started to use persistent Flash cookies and zombie cookies, but modern browsers and anti-malware software can now block or detect and remove such cookies.
The original developers of cookies intended that only the website that originally distributed cookies to users could retrieve them, therefore returning only data already possessed by the website. However, in practice programmers can circumvent this restriction. Possible consequences include:
- the placing of a personally-identifiable tag in a browser to facilitate web profiling , or
- use of cross-site scripting or other techniques to steal information from a user's cookies.
Cookies do have benefits. One is that for websites that one frequently visits that require a password, cookies may allow a user to not have to sign in every time. A cookie can also track one's preferences to show them websites that might interest them. Cookies make more websites free to use without any type of payment. Some of these benefits are also seen as negative. For example, one of the most common ways of theft is hackers taking one's username and password that a cookie saves. While many sites are free, they sell their space to advertisers. These ads, which are personalized to one's likes, can sometimes freeze one's computer or cause annoyance. Cookies are mostly harmless except for third-party cookies. These cookies are not made by the website itself but by web banner advertising companies. These third-party cookies are dangerous because they take the same information that regular cookies do, such as browsing habits and frequently visited websites, but then they share this information with other companies.
Cookies are often associated with pop-up windows because these windows are often, but not always, tailored to a person's preferences. These windows are an irritation because the close button may be strategically hidden in an unlikely part of the screen. In the worst cases, these pop-up ads can take over the screen and while one tries to close them, they can take one to another unwanted website.
Cookies are seen so negatively because they are not understood and go unnoticed while someone is simply surfing the internet. The idea that every move one makes while on the internet is being watched, would frighten most users.
Some users choose to disable cookies in their web browsers. Such an action can reduce some privacy risks, but may severely limit or prevent the functionality of many websites. All significant web browsers have this disabling ability built-in, with no external program required. As an alternative, users may frequently delete any stored cookies. Some browsers (such as Mozilla Firefox and Opera) offer the option to clear cookies automatically whenever the user closes the browser. A third option involves allowing cookies in general, but preventing their abuse. There are also a host of wrapper applications that will redirect cookies and cache data to some other location. Concerns exist that the privacy benefits of deleting cookies have been over-stated.
The process of profiling (also known as "tracking") assembles and analyzes several events, each attributable to a single originating entity, in order to gain information (especially patterns of activity) relating to the originating entity. Some organizations engage in the profiling of people's web browsing, collecting the URLs of sites visited. The resulting profiles can potentially link with information that personally identifies the individual who did the browsing.
Some web-oriented marketing-research organizations may use this practice legitimately, for example: in order to construct profiles of "typical internet users". Such profiles, which describe average trends of large groups of internet users rather than of actual individuals, can then prove useful for market analysis. Although the aggregate data does not constitute a privacy violation, some people believe that the initial profiling does.
Profiling becomes a more contentious privacy issue when data-matching associates the profile of an individual with personally-identifiable information of the individual.
Governments and organizations may set up honeypot websites – featuring controversial topics – with the purpose of attracting and tracking unwary people. This constitutes a potential danger for individuals.
When some users choose to disable HTTP cookies to reduce privacy risks as noted, new types of cookies were invented: since cookies are advertisers' main way of targeting potential customers, and some customers were deleting cookies, some advertisers started to use persistent Flash cookies and zombie cookies. In a 2009 study, Flash cookies were found to be a popular mechanism for storing data on the top 100 most visited sites. Another 2011 study of social media found that, "Of the top 100 web sites, 31 had at least one overlap between HTTP and Flash cookies." However, modern browsers and anti-malware software can now block or detect and remove such cookies.
Flash cookies, also known as local shared objects, work the same ways as normal cookies and are used by the Adobe Flash Player to store information at the user's computer. They exhibit a similar privacy risk as normal cookies, but are not as easily blocked, meaning that the option in most browsers to not accept cookies does not affect Flash cookies. One way to view and control them is with browser extensions or add-ons. Flash cookies are unlike HTTP cookies in a sense that they are not transferred from the client back to the server. Web browsers read and write these cookies and can track any data by web usage.
Although browsers such as Internet Explorer 8 and Firefox 3 have added a "Privacy Browsing" setting, they still allow Flash cookies to track the user and operate fully. However, the Flash player browser plugin can be disabled or uninstalled, and Flash cookies can be disabled on a per-site or global basis. Adobe's Flash and (PDF) Reader are not the only browser plugins whose past security defects have allowed spyware or malware to be installed: there have also been problems with Oracle's Java.
Some anti-fraud companies have realized the potential of evercookies to protect against and catch cyber criminals. These companies already hide small files in several places on the perpetrator's computer but hackers can usually easily get rid of these. The advantage to evercookies is that they resist deletion and can rebuild themselves.
There is controversy over where the line should be drawn on the use of this technology. Cookies store unique identifiers on a person's computer that are used to predict what one wants. Many advertisement companies want to use this technology to track what their customers are looking at online. This is known as online behavioral advertising which allows advertisers to keep track of the consumer's website visits to personalize and target advertisements. Evercookies enable advertisers to continue to track a customer regardless of whether their cookies are deleted or not. Some companies are already using this technology but the ethics are still being widely debated.
Anonymizer "nevercookies" are part of a free Firefox plugin that protects against evercookies. This plugin extends Firefox's private browsing mode so that users will be completely protected from evercookies. Nevercookies eliminate the entire manual deletion process while keeping the cookies users want like browsing history and saved account information.
A device fingerprint is information collected about the software and hardware of a remote computing device for the purpose of identifying individual devices even when persistent cookies (and also zombie cookies) can't be read or stored in the browser, the client IP address is hidden, and even if one switches to another browser on the same device. This may allow a service provider to detect and prevent identity theft and credit card fraud, but also to compile long-term records of individuals' browsing histories even when they're attempting to avoid tracking, raising a major concern for internet privacy advocates.
Third Party Requests
Third Party Requests are HTTP data connections from client devices to addresses in the web which are different than the website the user is currently surfing on. Many alternative tracking technologies to cookies are based on third party requests. Their importance has increased during the last years and even accelerated after Mozilla (2019), Apple (2020), and google (2022) have announced to block third party cookies by default. Third requests may be used for embedding external content (e.g. advertisements) or for loading external resources and functions (e.g. images, icons, fonts, captchas, JQuery resources and many others). Dependent on the type of resource loaded, such requests may enable third parties to execute a device fingerprint or place any other kind of marketing tag. Irrespective of the intention, such requests do often disclose information that may be sensitive, and they can be used for tracking either directly or in combination with other personally identifiable information . Most of the requests disclose referrer details that reveal the full URL of the actually visited website. In addition to the referrer URL further information may be transmitted by the use of other request methods such as HTTP POST. Since 2018 Mozilla partially mitigates the risk of third party requests by cutting the referrer information when using the private browsing mode. However, personal information may still be revealed to the requested address in other areas of the HTTP-header.
Photographs on the Internet
Today many people have digital cameras and post their photographs online, for example street photography practitioners do so for artistic purposes and social documentary photography practitioners do so to document people in everyday life. The people depicted in these photos might not want them to appear on the Internet. Police arrest photos, considered public record in many jurisdictions, are often posted on the Internet by online mug shot publishing sites.
Some organizations attempt to respond to this privacy-related concern. For example, the 2005 Wikimania conference required that photographers have the prior permission of the people in their pictures, albeit this made it impossible for photographers to practice candid photography and doing the same in a public place would violate the photographers' free speech rights. Some people wore a "no photos" tag to indicate they would prefer not to have their photo taken .
Face recognition technology can be used to gain access to a person's private data, according to a new study. Researchers at Carnegie Mellon University combined image scanning, cloud computing and public profiles from social network sites to identify individuals in the offline world. Data captured even included a user's social security number. Experts have warned of the privacy risks faced by the increased merging of online and offline identities. The researchers have also developed an 'augmented reality' mobile app that can display personal data over a person's image captured on a smartphone screen. Since these technologies are widely available, users' future identities may become exposed to anyone with a smartphone and an internet connection. Researchers believe this could force a reconsideration of future attitudes to privacy.
Google Street View
Google Street View, released in the U.S. in 2007, is currently the subject of an ongoing debate about possible infringement on individual privacy. In an article entitled "Privacy, Reconsidered: New Representations, Data Practices, and the Geoweb", Sarah Elwood and Agnieszka Leszczynski (2011) argue that Google Street View "facilitate[s] identification and disclosure with more immediacy and less abstraction." The medium through which Street View disseminates information, the photograph, is very immediate in the sense that it can potentially provide direct information and evidence about a person's whereabouts, activities, and private property. Moreover, the technology's disclosure of information about a person is less abstract in the sense that, if photographed, a person is represented on Street View in a virtual replication of his or her own real-life appearance. In other words, the technology removes abstractions of a person's appearance or that of his or her personal belongings – there is an immediate disclosure of the person and object, as they visually exist in real life. Although Street View began to blur license plates and people's faces in 2008, the technology is faulty and does not entirely ensure against accidental disclosure of identity and private property.
Elwood and Leszczynski note that "many of the concerns leveled at Street View stem from situations where its photograph-like images were treated as definitive evidence of an individual's involvement in particular activities." In one instance, Ruedi Noser, a Swiss politician, barely avoided public scandal when he was photographed in 2009 on Google Street View walking with a woman who was not his wife – the woman was actually his secretary. Similar situations occur when Street View provides high-resolution photographs – and photographs hypothetically offer compelling objective evidence. But as the case of the Swiss politician illustrates, even supposedly compelling photographic evidence is sometimes subject to gross misinterpretation. This example further suggests that Google Street View may provide opportunities for privacy infringement and harassment through public dissemination of the photographs. Google Street View does, however, blur or remove photographs of individuals and private property from image frames if the individuals request further blurring and/or removal of the images. This request can be submitted, for review, through the "report a problem" button that is located on the bottom left-hand side of every image window on Google Street View, however, Google has made attempts to report a problem difficult by disabling the "Why are you reporting the street view" icon.
Search engines have the ability to track a user's searches. Personal information can be revealed through searches by the user's computer, account, or IP address being linked to the search terms used. Search engines have claimed a necessity to retain such information in order to provide better services, protect against security pressure, and protect against fraud. A search engine takes all of its users and assigns each one a specific ID number. Those in control of the database often keep records of where on the internet each member has traveled to. AOL's system is one example. AOL has a database 21 million members deep, each with their own specific ID number. The way that AOLSearch is set up, however, allows for AOL to keep records of all the websites visited by any given member. Even though the true identity of the user isn't known, a full profile of a member can be made just by using the information stored by AOLSearch. By keeping records of what people query through AOLSearch, the company is able to learn a great deal about them without knowing their names.
Search engines also are able to retain user information, such as location and time spent using the search engine, for up to ninety days. Most search engine operators use the data to get a sense of which needs must be met in certain areas of their field. People working in the legal field are also allowed to use information collected from these search engine websites. The Google search engine is given as an example of a search engine that retains the information entered for a period of three-fourths of a year before it becomes obsolete for public usage. Yahoo! follows in the footsteps of Google in the sense that it also deletes user information after a period of ninety days. Other search engines such as Ask! search engine has promoted a tool of "AskEraser" which essentially takes away personal information when requested. Some changes made to internet search engines included that of Google's search engine. Beginning in 2009, Google began to run a new system where the Google search became personalized. The item that is searched and the results that are shown remembers previous information that pertains to the individual. Google search engine not only seeks what is searched but also strives to allow the user to feel like the search engine recognizes their interests. This is achieved by using online advertising. A system that Google uses to filter advertisements and search results that might interest the user is by having a ranking system that tests relevancy that include observation of the behavior users exude while searching on Google. Another function of search engines is the predictability of location. Search engines are able to predict where one's location is currently by locating IP Addresses and geographical locations.
Some solutions to being able to protect user privacy on the internet can include programs such as "Rapleaf" which is a website that has a search engine that allows users to make all of one's search information and personal information private. Other websites that also give this option to their users are Facebook and Amazon.
Privacy focused search engines/browsers
- Brave Browser: Brave browser is free software that reports to be privacy-first website browsing services, blocking online trackers and ads, and not tracking users' browsing data.
- DuckDuckGo: DuckDuckGo is a meta-search engine that combines the search results from various search engines (excluding Google) and providing some unique services like using search boxes on various websites and providing instant answers out of the box.
- Qwant: is an EU-based web-search engine that is focusing on privacy. It has its own index and has servers hosted in the European Union.
- Searx: a free and open source privacy-oriented meta-search engine which is based on a number of decentralized instances. There are a number of existing public instances, but any user can create their own if they desire.
- Fireball: Fireball is Germany's first search engine and obtains web results from various sources (mainly Bing). Fireball is not collecting any user information. All servers are stationed in Germany, a plus considering the German legislation tends to respect privacy rights better than many other European countries.
- MetaGer: MetaGer is a meta-search engine (obtains results from various sources) and in Germany by far the most popular safe search engine. MetaGer uses similar safety features as Fireball.
- Ixquick: IxQuick is a Dutch-based meta-search engine (obtains results from various sources). It commits also to the protection of the privacy of its users. Ixquick uses similar safety features as Fireball.
- Yacy: Yacy is a decentralized-search engine developed on the basis of a community project, which started in 2005. The search engine follows a slightly different approach to the two previous ones, using a peer-to-peer principle that does not require any stationary and centralized servers. This has its disadvantages but also the simple advantage of greater privacy when surfing due to basically no possibility of hacking.
- Search Encrypt: Search Encrypt is an internet search engine that prioritizes maintaining user privacy and avoiding the filter bubble of personalized search results. It differentiates itself from other search engines by using local encryption on searches and delayed history expiration.
- Tor Browser (The Onion Router): Tor Browser is free software that provides access to anonymised network that enables anonymous communication. It directs the internet traffic through multiple relays. This encryption method prevents others from tracking a certain user, thus allowing user's IP address and other personal information to be concealed.
The advent of the Web 2.0 has caused social profiling and is a growing concern for internet privacy. Web 2.0 is the system that facilitates participatory information sharing and collaboration on the internet, in social networking media websites like Facebook, Instagram, Twitter, and MySpace. These social networking sites have seen a boom in their popularity starting from the late 2000s. Through these websites, many people are giving their personal information out on the internet.
It has been a topic of discussion of who is held accountable for the collection and distribution of personal information. Some blame social networks, because they are responsible for storing the information and data, while others blame the users who put their information on these sites. This relates to the ever-present issue of how society regards social media sites. There is a growing number of people that are discovering the risks of putting their personal information online and trusting a website to keep it private. Yet in a recent study, researchers found that young people are taking measures to keep their posted information on Facebook private to some degree. Examples of such actions include managing their privacy settings so that certain content can be visible to "Only Friends" and ignoring Facebook friend requests from strangers.
In 2013 a class action lawsuit was filed against Facebook alleging the company scanned user messages for web links, translating them to “likes” on the user's Facebook profile. Data lifted from the private messages was then used for targeted advertising, the plaintiffs claimed. "Facebook's practice of scanning the content of these messages violates the federal Electronic Communications Privacy Act (ECPA also referred to as the Wiretap Act), as well as California's Invasion of Privacy Act (CIPA), and section 17200 of California's Business and Professions Code," the plaintiffs said. This shows that once information is online it is no longer completely private. It is an increasing risk because younger people are having easier internet access than ever before, therefore they put themselves in a position where it is all too easy for them to upload information, but they may not have the caution to consider how difficult it can be to take that information down once it is out in the open. This is becoming a bigger issue now that so much of society interacts online which was not the case fifteen years ago. In addition, because of the quickly evolving digital media arena, people's interpretation of privacy is evolving as well, and it is important to consider that when interacting online. New forms of social networking and digital media such as Instagram and Snapchat may call for new guidelines regarding privacy. What makes this difficult is the wide range of opinions surrounding the topic, so it is left mainly up to individual judgement to respect other people's online privacy in some circumstances.
Privacy issues of medical applications
With the rise of technology focused applications, there has been a rise of medical apps available to users on smart devices. In a survey of 29 migraine management specific applications, researcher Mia T. Minen (et al) discovered 76% had clear privacy policies, with 55% of the apps stated using the user data from these giving data to third parties for the use of advertising. The concerns raised discusses the applications without accessible privacy policies, and even more so - applications that aren't properly adhering to the Health Insurance Portability and Accountability Act (HIPAA) are in need of proper regulation, as these apps store medical data with identifiable information on a user.
Internet service providers
Internet users obtain internet access through an internet service provider (ISP). All data transmitted to and from users must pass through the ISP. Thus, an ISP has the potential to observe users' activities on the internet. ISPs can breach personal information such as transaction history, search history, and social media profiles of users. Hackers could use this opportunity to hack ISP and obtain sensitive information of victims.
However, ISPs are usually prohibited from participating in such activities due to legal, ethical, business, or technical reasons.
Normally ISPs do collect at least some information about the consumers using their services. From a privacy standpoint, ISPs would ideally collect only as much information as they require in order to provide internet connectivity (IP address, billing information if applicable, etc.).
Which information an ISP collects, what it does with that information, and whether it informs its consumers, pose significant privacy issues. Beyond the usage of collected information typical of third parties, ISPs sometimes state that they will make their information available to government authorities upon request. In the US and other countries, such a request does not necessarily require a warrant.
An ISP cannot know the contents of properly-encrypted data passing between its consumers and the internet. For encrypting web traffic, https has become the most popular and best-supported standard. Even if users encrypt the data, the ISP still knows the IP addresses of the sender and of the recipient. (However, see the IP addresses section for workarounds.)
An Anonymizer such as I2P – The Anonymous Network or Tor can be used for accessing web services without them knowing one's IP address and without one's ISP knowing what the services are that one accesses. Additional software has been developed that may provide more secure and anonymous alternatives to other applications. For example, Bitmessage can be used as an alternative for email and Cryptocat as an alternative for online chat. On the other hand, in addition to End-to-End encryption software, there are web services such as Qlink which provide privacy through a novel security protocol which does not require installing any software.
While signing up for internet services, each computer contains a unique IP, Internet Protocol address. This particular address will not give away private or personal information, however, a weak link could potentially reveal information from one's ISP.
General concerns regarding internet user privacy have become enough of a concern for a UN agency to issue a report on the dangers of identity fraud. In 2007, the Council of Europe held its first annual Data Protection Day on January 28, which has since evolved into the annual Data Privacy Day.
T-Mobile USA doesn't store any information on web browsing. Verizon Wireless keeps a record of the websites a subscriber visits for up to a year. Virgin Mobile keeps text messages for three months. Verizon keeps text messages for three to five days. None of the other carriers keep texts of messages at all, but they keep a record of who texted who for over a year. AT&T Mobility keeps for five to seven years a record of who text messages who and the date and time, but not the content of the messages. Virgin Mobile keeps that data for two to three months.[needs update]
HTML5 is the latest version of Hypertext Markup Language specification. HTML defines how user agents, such as web browsers, are to present websites based upon their underlying code. This new web standard changes the way that users are affected by the internet and their privacy on the internet. HTML5 expands the number of methods given to a website to store information locally on a client as well as the amount of data that can be stored. As such, privacy risks are increased. For instance, merely erasing cookies may not be enough to remove potential tracking methods since data could be mirrored in web storage, another means of keeping information in a user's web browser. There are so many sources of data storage that it is challenging for web browsers to present sensible privacy settings. As the power of web standards increases, so do potential misuses.
HTML5 also expands access to user media, potentially granting access to a computer's microphone or webcam, a capability previously only possible through the use of plug-ins like Flash. It is also possible to find a user's geographical location using the geolocation API. With this expanded access comes increased potential for abuse as well as more vectors for attackers. If a malicious site was able to gain access to a user's media, it could potentially use recordings to uncover sensitive information thought to be unexposed. However, the World Wide Web Consortium, responsible for many web standards, feels that the increased capabilities of the web platform outweigh potential privacy concerns. They state that by documenting new capabilities in an open standardization process, rather than through closed source plug-ins made by companies, it is easier to spot flaws in specifications and cultivate expert advice.
Big data is generally defined as the rapid accumulation and compiling of massive amounts of information that is being exchanged over digital communication systems. The data is large (often exceeding exabytes) and cannot be handled by conventional computer processors, and are instead stored on large server-system databases. This information is assessed by analytic scientists using software programs; which paraphrase this information into multi-layered user trends and demographics. This information is collected from all around the internet, such as by popular services like Facebook, Google, Apple, Spotify or GPS systems. Big data provides companies with the ability to:
- Infer detailed psycho-demographic profiles of internet users, even if they were not directly expressed or indicated by users.
- Inspect product availability and optimize prices for maximum profit while clearing inventory.
- Swiftly reconfigure risk portfolios in minutes and understand future opportunities to mitigate risk.
- Mine customer data for insight, and create advertising strategies for customer acquisition and retention.
- Identify customers who matter the most.

Other potential Internet privacy risks
- Cross-device tracking identifies users' activity across multiple devices.
- Massive personal data extraction through mobile device apps that receive carte-blanche-permissions for data access upon installation.
- Malware is a term short for "malicious software" and is used to describe software to cause damage to a single computer, server, or computer network whether that is through the use of a virus, trojan horse, spyware, etc.
- Spyware is a piece of software that obtains information from a user's computer without that user's consent.
- A web bug is an object embedded into a web page or email and is usually invisible to the user of the website or reader of the email. It allows checking to see if a person has looked at a particular website or read a specific email message.
- Phishing is a criminally fraudulent process of trying to obtain sensitive information such as user names, passwords, credit card or bank information. Phishing is an internet crime in which someone masquerades as a trustworthy entity in some form of electronic communication.
- Pharming is a hacker's attempt to redirect traffic from a legitimate website to a completely different internet address. Pharming can be conducted by changing the hosts file on a victim's computer or by exploiting a vulnerability on the DNS server.
- Social engineering where people are manipulated or tricked into performing actions or divulging confidential information.
- Malicious proxy server (or other "anonymity" services).
- Use of weak passwords that are short, consist of all numbers, all lowercase or all uppercase letters, or that can be easily guessed such as single words, common phrases, a person's name, a pet's name, the name of a place, an address, a phone number, a social security number, or a birth date.
- Use of recycled passwords or the same password across multiple platforms which have become exposed from a data breach.
- Using the same login name and/or password for multiple accounts where one compromised account leads to other accounts being compromised.
- Allowing unused or little used accounts, where unauthorized use is likely to go unnoticed, to remain active.
- Using out-of-date software that may contain vulnerabilities that have been fixed in newer, more up-to-date versions.
- WebRTC is a protocol which suffers from a serious security flaw that compromises the privacy of VPN tunnels, by allowing the true IP address of the user to be read. It is enabled by default in major browsers such as Firefox and Google Chrome.
Reduction of risks to Internet privacy
Inc. magazine reports that the Internet's biggest corporations have hoarded Internet users' personal data and sold it for large financial profits. The magazine reports on a band of startup companies that are demanding privacy and aiming to overhaul the social-media business. Popular privacy-focused mobile messaging apps include Wickr, Wire, and Signal, which provide peer-to-peer encryption and give the user the capacity to control what message information is retained on the other end; Ansa, an ephemeral chat application, also described as employing peer-to-peer encryption; and Omlet, an open mobile social network, described as giving the user control over their data so that if a user does not want their data saved, they are able to delete it from the data repository.
Noise society – protection through information overflow
According to Nicklas Lundblad, another perspective on privacy protection is the assumption that the quickly growing amount of information produced will be beneficial. The reasons for this are that the costs for the surveillance will raise and that there is more noise, noise being understood as anything that interferes the process of a receiver trying to extract private data from a sender.
In this noise society, the collective expectation of privacy will increase, but the individual expectation of privacy will decrease. In other words, not everyone can be analyzed in detail, but one individual can be. Also, in order to stay unobserved, it can hence be better to blend in with the others than trying to use for example encryption technologies and similar methods. Technologies for this can be called Jante-technologies after the Law of Jante, which states that you are nobody special. This view offers new challenges and perspectives for the privacy discussion.
While internet privacy is widely acknowledged as the top consideration in any online interaction, as evinced by the public outcry over SOPA/CISPA, public understanding of online privacy policies is actually being negatively affected by the current trends regarding online privacy statements. Users have a tendency to skim internet privacy policies for information regarding the distribution of personal information only, and the more legalistic the policies appear, the less likely users are to even read the information. Coupling this with the increasingly exhaustive license agreements companies require consumers to agree to before using their product, consumers are reading less about their rights.
Furthermore, if the user has already done business with a company, or is previously familiar with a product, they have a tendency to not read the privacy policies that the company has posted. As internet companies become more established, their policies may change, but their clients will be less likely to inform themselves of the change. This tendency is interesting because as consumers become more acquainted with the internet they are also more likely to be interested in online privacy. Finally, consumers have been found to avoid reading the privacy policies if the policies are not in a simple format, and even perceive these policies to be irrelevant. The less readily available terms and conditions are, the less likely the public is to inform themselves of their rights regarding the service they are using.
Concerns of internet privacy and real life implications
While dealing with the issue of internet privacy, one must first be concerned with not only the technological implications such as damaged property, corrupted files, and the like, but also with the potential for implications on their real lives. One such implication, which is rather commonly viewed as being one of the most daunting fears risks of the internet, is the potential for identity theft. Although it is a typical belief that larger companies and enterprises are the usual focus of identity thefts, rather than individuals, recent reports seem to show a trend opposing this belief. Specifically, it was found in a 2007 "Internet Security Threat Report" that roughly ninety-three percent of "gateway" attacks were targeted at unprepared home users. The term "gateway attack" was used to refer to an attack which aimed not at stealing data immediately, but rather at gaining access for future attacks.
According to Symantec's "Internet Security Threat Report", this continues despite the increasing emphasis on internet security due to the expanding "underground economy". With more than fifty percent of the supporting servers located in the United States, this underground economy has become a haven for internet thieves, who use the system in order to sell stolen information. These pieces of information can range from generic things such as a user account or email to something as personal as a bank account number and PIN.
While the processes these internet thieves use are abundant and unique, one popular trap unsuspecting people fall into is that of online purchasing. This is not to allude to the idea that every purchase one makes online will leave them susceptible to identity theft, but rather that it increases the chances. In fact, in a 2001 article titled "Consumer Watch", the popular online site PC World went as far as calling secure e-shopping a myth. Though unlike the gateway attacks mentioned above, these incidents of information being stolen through online purchases generally are more prevalent in medium to large e-commerce sites, rather than smaller individualized sites. This is assumed to be a result of the larger consumer population and purchases, which allow for more potential leeway with information.
Ultimately, however, the potential for a violation of one's privacy is typically out of their hands after purchasing from an online "e-tailer" or store. One of the most common forms in which hackers receive private information from online e-tailers actually comes from an attack placed upon the site's servers responsible for maintaining information about previous transactions. For as experts explain, these e-tailers are not doing nearly enough to maintain or improve their security measures. Even those sites that clearly present a privacy or security policy can be subject to hackers’ havoc as most policies only rely upon encryption technology which only applies to the actual transfer of a customer's data. However, with this being said, most e-tailers have been making improvements, going as far as covering some of the credit card fees if the information's abuse can be traced back to the site's servers.
As one of the largest growing concerns American adults have of current internet privacy policies, identity and credit theft remain a constant figure in the debate surrounding privacy online. A 1997 study by the Boston Consulting Group showed that participants of the study were most concerned about their privacy on the internet compared to any other media. However, it is important to recall that these issues are not the only prevalent concerns society has. Another prevalent issue remains members of society sending disconcerting emails to one another. It is for this reason in 2001 that for one of the first times the public expressed approval of government intervention in their private lives.
With the overall public anxiety regarding the constantly expanding trend of online crimes, in 2001 roughly fifty-four percent of Americans polled showed a general approval for the FBI monitoring those emails deemed suspicious. Thus, it was born the idea for the FBI program: "Carnivore", which was going to be used as a searching method, allowing the FBI to hopefully home in on potential criminals. Unlike the overall approval of the FBI's intervention, Carnivore was not met with as much of a majority's approval. Rather, the public seemed to be divided with forty-five percent siding in its favor, forty-five percent opposed to the idea for its ability to potentially interfere with ordinary citizen's messages, and ten percent claiming indifference. While this may seem slightly tangent to the topic of internet privacy, it is important to consider that at the time of this poll, the general population's approval on government actions was declining, reaching thirty-one percent versus the forty-one percent it held a decade prior. This figure in collaboration with the majority's approval of FBI intervention demonstrates an emerging emphasis on the issue of internet privacy in society and more importantly, the potential implications it may hold on citizens’ lives.
Online users must seek to protect the information they share with online websites, specifically social media. In today's Web 2.0 individuals have become the public producers of personal information. Users create their own digital trails that hackers and companies alike capture and utilize for a variety of marketing and advertisement targeting. A recent paper from the Rand Corporation claims "privacy is not the opposite of sharing – rather, it is control over sharing." Internet privacy concerns arise from the surrender of personal information to engage in a variety of acts, from transactions to commenting in online forums. Protection against invasions of online privacy will require individuals to make an effort informing and protecting themselves via existing software solutions, to pay premiums for such protections or require individuals to place greater pressure on governing institutions to enforce privacy laws and regulations regarding consumer and personal information.
Laws and regulations
Global privacy policies
European General Data protection regulation
As per June 2020, typical cookie implementations are not compliant to this regulation, and other practices such as device fingerprinting, cross-website-logins  or 3rd party-requests are typically not disclosed, even though many opinions consider such methods in scope of the GDPR. The reason for this controversary is the ePrivacy-Directive 2009/136/EC which is still unchanged in force. An updated version of this directive, formulated as ePrivacy Regulation, shall enlarge the scope from cookies only to any type of tracking method. It shall furthermore cover any kind of electronic communication channels such as Skype or WhatsApp. The new ePrivacy-Regulation was planned to come in force together with the GDPR, but as per July 2020 it was still under review. Some people assume that lobbying is the reason for this massive delay.
Irrespective of the pending ePrivacy-Regulation, the European High Court has decided in October 2019 (case C-673/17) that the current law is not fulfilled if the disclosed information in the cookie disclaimer is imprecise, or if the consent checkbox is pre-checked. Consequently, many cookie disclaimers that were in use at that time were confirmed to be incompliant to the current data protection laws. However, even this high court judgement only refers to cookies and not to other tracking methods.
Internet privacy in China
This section needs additional citations for verification. (June 2014) (Learn how and when to remove this template message)
One of the most popular topics of discussion in regards to internet privacy is China. Although China is known for its remarkable reputation on maintaining internet privacy among many online users, it could potentially be a major jeopardy to the lives of many online users who have their information exchanged on the web on a regular basis. For instance, in China, there is a new software that will enable the concept of surveillance among the majority of online users and present a risk to their privacy. The main concern with privacy of internet users in China is the lack thereof. China has a well known policy of censorship when it comes to the spread of information through public media channels. Censorship has been prominent in Mainland China since the communist party gained power in China over 60 years ago. With the development of the internet, however, privacy became more of a problem for the government. The Chinese Government has been accused of actively limiting and editing the information that flows into the country via various media. The internet poses a particular set of issues for this type of censorship, especially when search engines are involved. Yahoo! for example, encountered a problem after entering China in the mid-2000s. A Chinese journalist, who was also a Yahoo! user, sent private emails using the Yahoo! server regarding the Chinese government. Yahoo! provided information to the Chinese government officials track down journalist, Shi Tao. Shi Tao allegedly posted state secrets to a New York based website. Yahoo provided incriminating records of the journalist's account logins to the Chinese government and thus, Shi Tao was sentenced to ten years in prison. These types of occurrences have been reported numerous times and have been criticized by foreign entities such as the creators of the Tor anonymity network, which was designed to circumvent network surveillance in multiple countries.
User privacy in China is not as cut-and-dry as it is in other parts of the world. China, reportedly[according to whom?], has a much more invasive policy when internet activity involves the Chinese government. For this reason, search engines are under constant pressure to conform to Chinese rules and regulations on censorship while still attempting to keep their integrity. Therefore, most search engines operate differently in China than in other countries, such as the US or Britain, if they operate in China at all. There are two types of intrusions that occur in China regarding the internet: the alleged intrusion of the company providing users with internet service, and the alleged intrusion of the Chinese government. The intrusion allegations made against companies providing users with internet service are based upon reports that companies, such as Yahoo! in the previous example, are using their access to the internet users' private information to track and monitor users' internet activity. Additionally, there have been reports that personal information has been sold. For example, students preparing for exams would receive calls from unknown numbers selling school supplies. The claims made against the Chinese government lie in the fact that the government is forcing internet-based companies to track users private online data without the user knowing that they are being monitored. Both alleged intrusions are relatively harsh and possibly force foreign internet service providers to decide if they value the Chinese market over internet privacy. Also, many websites are blocked in China such as Facebook and Twitter. However many Chinese internet users use special methods like a VPN to unblock websites that are blocked.
Internet privacy in Sweden
This section's tone or style may not reflect the encyclopedic tone used on Wikipedia. (April 2021) (Learn how and when to remove this template message)
Sweden is often considered to be at the forefront of internet use and regulations. On 11 May 1973 Sweden enacted the Data Act − the world's first national data protection law. They are constantly innovating the way that the internet is used and how it impacts their people. In 2012, Sweden received a Web Index Score of 100, a score that measures how the internet significantly influences political, social, and economic impact, placing them first among 61 other nations. Sweden received this score while in the process of exceeding new mandatory implementations from the European Union. Sweden placed more restrictive guidelines on the directive on intellectual property rights enforcement (IPRED) and passed the FRA-law in 2009 that allowed for the legal sanctioning of surveillance of internet traffic by state authorities. The FRA has a history of intercepting radio signals and has stood as the main intelligence agency in Sweden since 1942. Sweden has a mixture of government's strong push towards implementing policy and citizens' continued perception of a free and neutral internet. Both of the previously mentioned additions created controversy by critics but they did not change the public perception even though the new FRA-law was brought in front of the European Court of Human Rights for human rights violations. The law was established by the National Defense Radio Establishment (Forsvarets Radio Anstalt - FRA) to eliminate outside threats. However, the law also allowed for authorities to monitor all cross-border communication without a warrant. Sweden's recent emergence into internet dominance may be explained by their recent climb in users. Only 2% of all Swedes were connected to the internet in 1995 but at last count in 2012, 89% had broadband access. This was due in large part once again to the active Swedish government introducing regulatory provisions to promote competition among internet service providers. These regulations helped grow web infrastructure and forced prices below the European average. To add to the intrigue around Sweden's laws and regulations, one must also mention how copyright laws evolved in Sweden. Sweden was the birthplace of the Pirate Bay, an infamous file-sharing website. File sharing has been illegal in Sweden since it was developed, however, there was never any real fear of being persecuted for the crime until 2009 when the Swedish Parliament was the first in the European Union to pass the intellectual property rights directive. This directive persuaded internet service providers to announce the identity of suspected violators. A final piece of legislation worth mentioning when discussing Sweden's regulations is the infamous centralized block list. The list is generated by authorities and was originally crafted to eliminate sites hosting child pornography. However, there is no legal way to appeal a site that ends up on the list and as a result, many non-child pornography sites have been blacklisted. It is important to consider that Sweden's government enjoys a high level of trust from their citizens. Without this trust, many of these regulations would not be possible and thus many of these regulations may only be feasible in the Swedish context.
Internet privacy in the United States
It has been suggested that this section be checked to ensure a neutral point of view. (April 2021) (Learn how and when to remove this template message)
With the Republicans in control of all three branches of the U.S. government, lobbyists for internet service providers (ISPs) and tech firms persuaded lawmakers to dismantle regulations to protect privacy which had been made during the Obama administration. These FCC rules had required ISPs to get "explicit consent" before gathering and selling their private internet information, such as the consumers' browsing histories, locations of businesses visited and applications used. Trade groups wanted to be able to sell this information for profit. Lobbyists persuaded Republican senator Jeff Flake and Republican representative Marsha Blackburn to sponsor legislation to dismantle internet privacy rules; Flake received $22,700 in donations and Blackburn received $20,500 in donations from these trade groups. On March 23, 2017, abolition of these privacy protections passed on a narrow party-line vote. In June 2018, California passed the law restricting companies from sharing user data without permission. Also, users would be informed to whom the data is being sold and why. On refusal to sell the data, companies are allowed to charge a little higher to these consumers. Mitt Romney, despite approving a Twitter comment of Mark Cuban during a conversation with Glenn Greenwald about anonymity in January 2018, was revealed as the owner of the Pierre Delecto lurker account in October 2019.
Used by government agencies are array of technologies designed to track and gather internet users' information are the topic of much debate between privacy advocates, civil liberties advocates and those who believe such measures are necessary for law enforcement to keep pace with rapidly changing communications technology.
- Following a decision by the European Union's council of ministers in Brussels, in January 2009, the UK's Home Office adopted a plan to allow police to access the contents of individuals' computers without a warrant. The process, called "remote searching", allows one party, at a remote location, to examine another's hard drive and internet traffic, including email, browsing history and websites visited. Police across the EU are now permitted to request that the British police conduct a remote search on their behalf. The search can be granted, and the material gleaned turned over and used as evidence, on the basis of a senior officer believing it necessary to prevent a serious crime. Opposition MPs and civil liberties advocates are concerned about this move toward widening surveillance and its possible impact on personal privacy. Says Shami Chakrabarti, director of the human rights group Liberty, "The public will want this to be controlled by new legislation and judicial authorisation. Without those safeguards it's a devastating blow to any notion of personal privacy."
- The FBI's Magic Lantern software program was the topic of much debate when it was publicized in November 2001. Magic Lantern is a Trojan Horse program that logs users' keystrokes, rendering encryption useless to those infected.
Children and internet privacy
Internet privacy is a growing concern with children and the content they are able to view. Aside from that, many concerns for the privacy of email, the vulnerability of internet users to have their internet usage tracked, and the collection of personal information also exist. These concerns have begun to bring the issues of internet privacy before the courts and judges.

T-Mobile USA doesn't keep any information on Web browsing activity. Verizon, on the other hand, keeps some information for up to a year that can be used to ascertain if a particular phone visited a particular Web site. According to the sheet, Sprint Nextel Corp.'s Virgin Mobile brand keeps the text content of text messages for three months. Verizon keeps it for three to five days. None of the other carriers keep texts at all, but they keep records of who texted who for more than a year. The document says AT&T keeps for five to seven years a record of who text messages who—and when, but not the content of the messages. Virgin Mobile only keeps that data for two to three months.
