Intypedia - Portada.png

Intypedia is an educational non-profit project developed by the Technical University of Madrid. It’s a visual encyclopedia on information security. The aim of this Project is to spread knowledge of this topic through a series of videos created by renowned experts, while using a language that is accessible to a broad audience. The encyclopedia covers subjects like cryptography, network security, malware, Internet security, information security management systems (ISMS), risk management, etc.

History of the Project[edit]

The development of the so-called Information Society has changed the way people interact with each other and the way they see the reality that surrounds them. Multimedia technologies have become a great medium not only for entertainment and leisure, but also for developing and spreading knowledge and culture.

However, it wasn’t easy to find quality multimedia information created by experts on subjects related to information security. Furthermore, the little videos that could be found online in 2009 on channels such as YouTube, for example, didn’t meet the philosophy of a continuous project following a teaching method. There were only videos of conferences or presentations on information security by different speakers, without a storyline that would allow the correct online education on information security.

The Intypedia project emerges in 2010 to fulfil this need in the new era of non-profit online teaching.

The name Intypedia was chosen because it is a portmanteau of Information Security Encyclopedia and because in 2010 there weren’t any results for Intypedia in any of the popular search engines (Google, Yahoo! and Bing). This would allow the correct tracking of the project’s online circulation.

In order for Intypedia to reach a broader audience, it uses the YouTube video channel of the Technical University of Madrid, social networks and the Thematic Network on Cryptography and Information Security: CRIPTORED. Since 1999, this network has been offering thousands of free distribution documents about security. In fact, Intypedia is a project within this thematic network.

Intypedia was made public in late September 2010, with the collaboration of important Spanish blogs and websites on security. It received a great response and the first videos were among the most seen on the Spanish EDU channel on YouTube. During the first three months, it was played 25000 times, which is a high amount amongst educational videos.


In 2009, Jorge Ramió Aguirre, professor at the Technical University of Madrid and director of the Intypedia Project, along with Professor Ángeles Mahillo García, realise the need to create educational videos for the subject they teach at the university: Basics of Information Security. This is a core subject in today’s technological society and there wasn’t an adequate offer in multimedia information.

For this reason, they decide to create a visual encyclopedia containing lessons in the format of 12 minute videos. The content of these educational videos would be elaborated by prestigious experts in information security.

The video scripts are written so that the lessons can be understood not only by security experts, but also by university students and general Internet users. In this way, the quality and clarity of the contents are an added value to the project.

Two animated characters, Alice and Bob -named after the placeholder names used for archetypal characters in fields such as cryptography and physics- are in charge of presenting the lesson in each video. Along with the video, each lesson will come with three extra documents available for downloading from the project’s website: the script of the video, a slideshow with additional information on the subject and a document with exercises or questions to use for self-assessment. Both characters have a fluid conversation in each video, giving basic information to one other and answering each other’s questions regarding the topic that is being presented. All of this takes place in the virtual space of the Intypedia library.

Production Team[edit]

At the beginning of 2010, Professor Jorge Ramió asks Alfonso Muñoz, PhD in Telecommunications, to plan and design the technical aspects of this educational project. After several months of work the final team is decided:

Director of the project: Dr. Jorge Ramió Aguirre (Technical University of Madrid)

Technical Director: Dr. Alfonso Muñoz Muñoz (Technical University of Madrid)

Web design and Programming: Miguel Luis González, Telecommunications Technical Engineer

Graphic Design and Infographics: Ángel Castillo. r3b0rn Video&Design Studio.

Translation: Dalia Puertas, B.A. in Translation and Interpreting.

This team produces an educational video each month, in English and in Spanish. After six months of work, Intypedia was launched on the 27th of September 2010 with the presentation video and the first lesson.

Video Creation Process[edit]

Each video takes about a month to create and the costs are covered thanks to the sponsorship of the company GMV and others like ESET. The creation process of each video is as follows:

Intypedia - Alicia.png

1. An expert is asked to elaborate a script on a certain subject related to information security. Response time: indefinite – parallel work. The author sends the proposed script along with the slideshow and exercises.

2. Once the script is received, it is adapted for the Intypedia video format. Editors: Jorge Ramió and Alfonso Muñoz.

3. Feedback is sent to the author so they can accept the technical changes to the script.

4. The script is recorded in Spanish by broadcasters from CIFP José Luis Garci.

5. The wav audio files are adapted and sent to Infographics. Production: Alfonso Muñoz.

6. The script is animated and the video is created. Time: 2 to 3 weeks. Infographics: Ángel Castillo.

7. The script, slideshow and exercises are translated into English. Translator: Dalia Puertas.

8. The English audio is created in wav. Software: Natural Reader 9.0. Production: Alfonso Muñoz.

9. The Spanish video is received, viewed and edited. Time: from a couple of days to one week. Editors: Jorge Ramió and Alfonso Muñoz.

10. The script, slideshow and exercises are adapted to the Intypedia format to create the pdf documents available for downloading from the web. Jorge Ramió and Alfonso Muñoz.

11. The Spanish video is published on the Intypedia website. Total estimated time: 1 month.

12. The website is updated in Spanish. Programmer: Alfonso Muñoz.

13. The Spanish video is adapted to the English audio. Time: 1 week. Infographics: Ángel Castillo.

14. The English script, slideshow and exercises are adapted to the Intypedia format to create the pdf documents available for downloading from the web. Jorge Ramió and Alfonso Muñoz.

15. The English video is published on the Intypedia website. Total estimated time: two weeks after the Spanish video.

16. The website is updated in English. Programmer: Alfonso Muñoz.
