Firstly, you have just the air of hiding something, and two, you will still be recognized, given the sophistication of intelligent systems of facial recognition.

Reasons cubist

In cities like Moscow where there are around 100,000 cameras, such as London and several major us cities, it is easy to identify and catalog the people.

First, all of the information that we leave on the Internet available for the intelligent systems are used to put names on the photos. Social networks such as Facebook or Instagram alone provide amount of identification material.

Each time you take a égoportrait on Facebook or Google Photos, this image can be used to identify you on other pictures, such as those that are saved when you wander into a city arrest.

To confound recognition systems, researchers, such as Adam Harvey have developed techniques based on drawings inspired the cubists.

Easy to test with a phone

The agency AP, a london artist who applies the principles of Adam Harvey states “that it is necessary to scramble the decoding by applying colors and patterns random. The most important thing is to have colors of light and dark, such as black and white, high contrast colour, to confuse the systems with areas of shade and light on the face”.

The face recognition software to measure the key points of the face, such as eyes, nose and mouth, as well as the place where they meet and the distance that separates them.

To test the result of the patterns on his face, it is enough to perform a simple unlocking by facial detection of his phone.

The activists are familiar with the technique and use it in demonstrations pro-democracy such as Hong Kong or as in Russia to protest against privacy violations.

Russia and China are also the two largest exporters of surveillance systems of mass in the world. And in the United States, one adult in two is recorded in the data banks of the facial recognition of the police, according to a study by the law Center, Georgetown on technology and privacy, published in 2016.

Designers have designed eyeglasses that reflect the infrared light to blind the cameras. Other jewelry like this.
