Facial recognition, risk or security?

in STEMGeeks2 months ago
Greetings dear friends.

Earlier I told you about the risks of easy manipulation by AI software, which can alter the appearance of a person or place his image in a scene where it was not originally. But really facial recognition has become an everyday tool, providing security aspects in our day to day life, being used, for example, to unlock our cell phone or access the bank's mobile application.

Facial recognition is gradually bursting into different aspects, becoming a priority for many technology companies, either for use in their products, as in the case of Apple, which has implemented it as an entry key to various functions in their mobile devices; or as services provided to third parties, as in the case of airports that are nurturing their security and control with facial recognition programs.

But these tools require the image of citizens to be stored in the cloud and there is growing concern among many people about the use of this image and identification through artificial intelligence. They assume that, although this technology can provide us with great advances in security, it also implies that some people's rights could be violated.

For example, the London police have been using surveillance cameras with facial recognition and biometric tracking in the streets since last year, they have assured that it is not a normal recording process but rather a process where AI-based software scans the face of citizens and crosses it in real time with a database of suspects.

But this is a big dilemma, giving up privacy in exchange for security, and it seems that in this digital era we are entering the world of hypervigilance, like something out of science fiction. This situation raises questions such as where will the images come from to train the algorithm, who can have access to the images of citizens recorded in the street, and how long will this information be available on the Internet? And how long will this information be available on the network?

Another risk is the production of erroneous arrests due to false positives. One of the first cases of an erroneous arrest occurred in a neighborhood of Detroit, in the United States, in January 2020, a subject was arrested when he arrived at his home, he was only told he had an arrest warrant and was taken away, he spent 18 hours in detention without knowing the reason, after being released he learned that a facial recognition algorithm had confused him with another subject, now he has initiated legal action against this system in Detroit.

According to the London Metropolitan Police the system has been accurate 70% of the time, that is, there is a possibility of being treated as a suspect if you meet the facial features that the algorithm is looking for, and the problem is not that after a few hours and several uncomfortable situations the person caught by mistake is released, but we must remember that if someone who is arrested for any reason, and is proven innocent, the arrest remains registered in the police database.

On the side of the violation of people's privacy, activists and civil organizations are taking action to stop this form of surveillance, which they consider oppressive and an attack on human rights, as it gives the state the power to monitor and closely follow the movements of every citizen. China, the most advanced country in the implementation of this system, has installed an army of cameras in cities such as Shanghai, and its DragonFly eye system is capable of finding a person in just seven minutes.

As we can see, the use of Artificial Intelligence for facial recognition is closer to us than we think, although in many cases it offers us security, the system is so controversial that it deserves to be addressed in more detail and should be better regulated, since people have the right to know the use given to the biometric data collected in the streets and air terminals.
