It is one of the news that has attracted the most attention in the last hours in the technological world, the appearance of the Pixel 4 and its improved facial recognition system. How has Google achieved that most effective result?
The internet giant has acknowledged to the publication The Verge that he has dedicated himself to collecting the faces of passers-by from certain cities in the United States, to which he offered five dollars if they agreed to cede their image with a selfie.
This gallery of faces each unique has served Google to nourish its artificial intelligence system. These programs, like humans, need practice and example to learn why companies use large amounts of faces all different to make facial recognition the most effective.
The variety helps to avoid racial and gender prejudices that on other occasions the developers included in their intelligent systems. Apple allegedly used a billion images to develop the neural networks that manage its facial recognition system, one of the best in the market.

It is also appreciated that Google searches for these faces on the street and pays for those images and does not get them from the internet without the permission of their owners as others have done. To do this, participants have offered discount coupons for Starbucks and Amazon for $ 5.
Is it a fair price for voluntarily transferring our image to a large multinational? It depends on each one and our concept of privacy if we take into account that most of us already have photographs of us online that we have put up for free.
However, Google has ensured that these photographs will only remain stored in your system for 18 months, despite the fact that the forms that the participants had to sign indicated that they could be up to 5 years, as indicated in Gizmodo.
They also promise that the registration made by the system of our face when we use the facial recognition of the Pixel 4 will remain on the mobile and will not reach the cloud to preserve our privacy a bit.
Of all these faces, infrared, color and depth data would have been recorded. In addition to improving the facial recognition system so that we can unlock the phone or pay with it, Google also accompanies this system with the Motion Sense function.
In the video we can see how the model unlocks the phone with its face and then passes the songs with a simple gesture with the hand in the air and without needing to touch the phone. This novelty has been a rumor since the Google Soli Project was known that uses radar sensors to detect the movements of our hands, allowing us more freedom to navigate the mobile interface.
The Pixel 4 will be presented in the fall although there is still no official date, it will be then when we can test the effectiveness of these two novelties.
