Sousveillance (// soo-VAY-ləns; French pronunciation: [suvɛjɑ̃s]) is most commonly defined as the recording of an activity by a participant in the activity typically by way of small wearable or portable personal technologies.
Alternative definitions of both sur- and sous- veillance (the act of watching), in addition to the definition above, include:
- Surveillance is defined as cameras (or other sensors) affixed to property (real-estate, e.g. land, by way of posts or poles, or buildings), whereas sousveillance is defined as cameras (or other sensors) borne by people.
- Surveillance is the veillance of the authority (i.e. the veillance that has the capacity to prohibit other veillances), whereas sousveillance is the veillance of plurality (i.e. "crowd veillance" or watching, sensing, or the like, done by non authorities).
- Sousveillance has also been described as "inverse surveillance", based on the word surveillance (from the French sur, "from above", and veiller, "to watch"), and substituting the prefix sous, "from below".
While surveillance and sousveillance both generally refer to visual monitoring, the terms also denote other forms of monitoring such as audio surveillance or sousveillance. In the audio sense (e.g. recording of phone conversations) sousveillance is referred to as "one party consent".
Inverse surveillance is a subset of sousveillance with a particular emphasis on the "watchful vigilance from underneath" and a form of surveillance inquiry or legal protection involving the recording, monitoring, study, or analysis of surveillance systems, proponents of surveillance, and possibly also recordings of authority figures and their actions. Inverse surveillance is typically an activity undertaken by those who are generally the subject of surveillance, and may thus be thought of as a form of ethnography or ethnomethodology study (i.e. an analysis of the surveilled from the perspective of a participant in a society under surveillance).
Sousveillance typically involves community-based recording from first person perspectives, without necessarily involving any specific political agenda, whereas inverse-surveillance is a form of sousveillance that is typically directed at, or used to collect data to analyze or study, surveillance or its proponents (e.g., the actions of police or protestors at a protest rally).
The term "sousveillance", coined by Steve Mann, stems from the contrasting French words sur, meaning "above", and sous, meaning "below", i.e. "surveillance" denotes the "eye-in-the-sky" watching from above, whereas "sousveillance" denotes bringing the camera or other means of observation down to human level, either physically (mounting cameras on people rather than on buildings), or hierarchically (ordinary people doing the watching, rather than higher authorities or architectures doing the watching).
Inverse surveillance is a type of sousveillance. The more general concept of sousveillance goes beyond just inverse surveillance and the associated twentieth century political "us versus them" framework for citizens to photograph police, shoppers to photograph shopkeepers, or passengers to photograph taxicab drivers. Howard Rheingold commented on the site for his book Smart Mobs that this is similar to the pedestrian-driver concept, i.e. these are roles that many of us take both sides of, from time to time.
One of the things that brought inverse surveillance to light was the reactions of security guards to electric seeing aids and similar sousveillance practices. It seemed, early on, that the more cameras that were in an establishment, the more the guards disliked the use of an electric seeing aid, such as the EyeTap eyeglasses. It was through simply wearing electric seeing aids, as a passive observer, that it was discovered that surveillance and sousveillance can cause conflict and sometimes confrontation. This led some researchers to explore why the perpetuators of surveillance are suspicious of sousveillance, and thus defined the notion of inverse surveillance as a new and interesting facet of studies in sousveillance.
Since the year 2001, December 24 has been World Sousveillance Day with groups of participants in New York, Toronto, Boston, Florida, Vancouver, Japan, Spain and the United Kingdom. However, this designated day focuses only on hierarchical sousveillance, whereas there are a number of groups around the world working on combining the two forms of sousveillance.
An essay from Wired magazine predicts that sousveillance is an important development that will be on the rise in 2014.
Sousveillance of a state by its citizens has been credited with addressing many problems such as election fraud or electoral misdeeds, as well as providing good governance. For example, mobile phones were used in Sierra Leone and Ghana in 2007 for checking malpractices and intimidation during elections.
A recent area of research further developed at IWIS was the equilibrium between surveillance and sousveillance. Current "equiveillance theory" holds that sousveillance, to some extent, often reduces or eliminates the need for surveillance. In this sense it is possible to replace the Panoptic God's eye view of surveillance with a more community-building ubiquitous personal experience capture. Crimes, for example, might then be solved by way of collaboration among the citizenry rather than through the watching over the citizenry from above. But it is not so black-and-white as this dichotomy suggests. In particular, citizens watching over their neighbors is not necessarily "better" than the alternative: an increase in community self-reliance might be offset by an uncomfortable "nosy neighbor" effect. "Personal sousveillance" has been referred to as "coveillance" by Mann, Nolan and Wellman.
Copwatch is a network of US and Canadian volunteer organizations that "police the police." Copwatch groups usually engage in monitoring of the police, videotaping police activity, and educating the public about police misconduct. Fitwatch is a group who photograph Forward Intelligence Teams (police photographers) in the UK.
Personal sousveillance is the art, science, and technology of personal experience capture, processing, storage, retrieval, and transmission, such as lifelong audiovisual recording by way of cybernetic prosthetics, such as seeing-aids, visual memory aids, and the like. Even today's personal sousveillance technologies like camera phones and weblogs tend to build a sense of community, in contrast to surveillance that some have said is corrosive to community.
The legal, ethical, and policy issues surrounding personal sousveillance are largely yet to be explored, but there are close parallels to the social and legal norms surrounding recording of telephone conversations. When one or more parties to the conversation record it, we call that sousveillance, whereas when the conversation is recorded by a person who is not a party to the conversation (such as a prison guard violating a client-lawyer relationship), we call the recording "surveillance".
"Targeted sousveillance" refers to sousveillance of a specific individual by one or more other individuals. Usually the targeted individual is a representative or proponent of surveillance, so targeted sousveillance is often inverse surveillance or hierarchical sousveillance. "Hierarchical sousveillance" refers, for example, to citizens photographing police, shoppers photographing shopkeepers, or taxicab passengers photographing cab drivers. So, for example, targeting former White House security official Admiral John Poindexter with sousveillance follows this more political narrative.
Classy's Kitchen describes sousveillance as "another way to add further introspection to the commons that keeps society open but still makes the world smaller and safer". In this way sousveillance may be regarded as a possible replacement for surveillance. In this sur/sousveillance replacement, one can consider an operative social norm that would require cameras to be attached to a human operator. Under such a scenario, any objections to the camera could be raised by another human more easily than it would be to interact with a lamp post upon which is mounted a surveillance camera. Thus, the argument is that cameras attached to people ought to be less offensive than cameras attached to inanimate objects, because there is at least one responsible party present to operate the camera. This responsible-party argument is analogous to that used for operation of a motor vehicle, where a responsible driver is present, in contrast to remote or automated operation of a motor vehicle.
Beyond the political or breaching of hierarchical structure explored in academia, the more rapidly emerging discourse on sousveillance within industry is "personal sousveillance", namely the recording of an activity by a participant in the activity.
As the technologies get smaller and easier to use, the capture, recording, and playback of everyday life gets that much easier to initiate spontaneously in unexpected situations. For example, David Ollila, a manufacturer of video camera equipment, was trapped for four hours aboard a Comair plane at JFK Airport in New York City. When he recorded an interview with the pilot about the situation, the pilot called the police who then removed Ollila for questioning and removed everyone from the plane.
Recording a situation is only part of the sousveillance process. Communicating is also important. Video-sharing sites such as YouTube and photo-sharing sites such as Flickr play a vital role. For example, police agents provocateur were quickly revealed on YouTube when they infiltrated a demonstration in Montebello, Quebec, against the leaders of Canada, Mexico and the United States (August 2007). When the head of the Quebec police publicly stated that there was no police presence, a sousveillance video showed him to be wrong. When he revised his statement to say that the police provocateurs were peaceful observers, the same video showed them to be masked, wearing police boots, and in one case holding a rock.
There are many similar examples, such as the widely-viewed YouTube video of UCLA campus policemen tasering a student. In Russia, onboard cameras are so ubiquitous that thousands of videos of automobile accidents and close-call incidents have been uploaded. The unanticipated 2013 Russian meteor event was well documented from a dozen angles via the use of these devices.
Examples of alibi sousveillance
Many radio operators keep a complete recording of everything they transmit, so that they can use it to defend against allegations that they may have said or shown something on-air that is inappropriate.
More recently, Hasan Elahi, a University of Maryland professor, has produced a sousveillance for his entire life, after being detained at an airport because he shares the same name as a person on the US terrorist watchlist. Some of his sousveillance activities include using his cell phone as a tracking device, and publicly posting debit card and other transactions that document his actions.
Use of wearable cameras by police officers combined with video streaming and recording in an archive results in a record of the interactions of the officer with the public and with criminal suspects. The small cameras are made by Taser International, Looxcie, and probably other firms. Experiments with police use in Rialto, California in 2012 to 2013 resulted in a reduction of both complaints against officers and reduction in use of violence by officers. The public is shielded from police misconduct and the police officer from bogus complaints.
In the Neanderthal Parallax trilogy, the Homo neanderthalensis occupying a parallel universe have what are called companion implants. These are comprehensive recording and transmission devices, mounted in the forearm of each person. Their entire life is constantly monitored and sent to their alibi archive, a repository of recordings that are only accessible by their owner, or by the proper authorities when investigating an infraction, and in the latter case only in circumstances relevant to the investigation. Recordings are maintained after death; it is not made clear what the reasoning is for this and under what circumstances and or by whom a deceased person's archive can be accessed.
The plot of the 1995 movie Strange Days is based on a future where sousveillance recordings are made and sold as entertainment. The plot of the movie revolves around the murder of a celebrity by police officers that is recorded by a person secretly wearing one of the devices. In the movie, the recordings are made by a flat array of sensors that pick up signals from the brain stem. The sensors are usually hidden under a wig, and they record everything the person wearing them sees and hears. Recordings made while the person making them dies are called "blackjack" tapes.
The 2007 novel Halting State by Charles Stross and its sequel Rule 34 depict a 2020s Scotland in which wearable computing has a level of ubiquity similar to that of 2013's cell phones. The implications of a society in which anyone might be recording anything at any time are explored at length, particularly with respect to policing.
