Digital diary published an interesting article about the more developed facial recognition technology, revealing that Governments do not yet have the tools to protect the privacy of its citizens.

Detection and face recognition technology is becoming cheaper, faster and much more common. The question is whether people will be able to remain anonymous in the near future.

The signals digital and sensors that detect and recognize them expensive already not are a matter of science fiction. They are real and they are popping up everywhere, from shopping malls, bars and smart phones.

Then, what is what you protects from that the great brother follow your movements and invade your privacy? Starting from now, the technology is the only barrier significant.

Today, the technology not is so solid as to take you a photo to someone in the street and immediately know who is. Them processors of the computer not are it sufficiently fast as for scan through thousands of million of images in time real to find a coincidence between a face that not is in line with a photography in line. But that will come soon.

"Find a match between two pictures of people in the United States in real time would take four hours," said Alessandro Acquisti, Professor of technologies of the information and policies public of the Heinz College of Carnegie Mellon University. "That's too long to do so in real time. "But assuming (that is to produce) an improves constant in the time in the computer in cloud, soon could be more near that reality of what many of us thought".

Acquisti and his team of research at Carnegie Mellon have already developed an application for proof of concept for iPhone that can take a photo of a person in a matter of seconds display and your name, date of birth and social security number.

Currently, reference photos have to be charged to a database, but Acquisti said that processing speed will soon be fast enough to make the process online in an instant.

Since 1993, the rate of false positives for the identification of faces has been reduced by half every two years, reaching 0.003% at the end of last year, according to the National Institute of standards and technology of the United States.

Although computers still have difficulties to identify faces in low light or poor photographic quality, programs can now capture the profile of a face, build a 3D model of it, rotate the photo and identify the person to which the face belongs.

If a future that always you be identified really is around the corner, what will prevent that advertisers or even the Government put names to previously anonymous faces that come to a store, walking down the street or protest against a Convention? That's what the Federal Trade Commission (FTC) tried to find out in a facial recognition in Washington Policy Conference last month.

The answer for now is the self-regulation of the sector. It Digital Signage Federation, a consortium of companies that operate them signals digital that detect or recognize them faces, developed guidelines of privacy that require that those consumers authorize be detected or recognized. But this 'authorization' can be granted in a way as simple as entering a shop that announces in its window that detects faces.

The defenders of privacy and lawyers representing companies of facial recognition support that he is needed to remove the imperfections of the system. By now, no law or regulation avoids that your face is detected or recognized without your consent.

"Is list the law of privacy of United States for the recognition facial?" Even is close to be it,"said Daniel Solove, Professor of the George Washington University School of law.

However, the solution is not easy. Warn people that a place is notably equipped with face detection technology means that the only way that people that are not detected would be to avoid that place. But what if you are a pharmacy and someone has to get a recipe?

¿Es posible un sistema de ‘No Rastrear’ (‘Do Not Track’) rostros? Incluso si esta tecnología pudiera ser desarrollada, no es posible pedir a todos que envíen una foto, y sería desagradable para muchos decidir no formar parte de un sistema que la mayoría cree que debería estar bajo autorización.

Algunos sugirieron la existencia de una línea roja que indicara un área de reconocimiento de rostros, o incluso entradas separadas. Pero ¿qué pasaría con las señales digitales en la acera?

“Usa una máscara”, dijo John Verdi, asesor del Electronic Privacy Information Center. Ésa es una idea.
