In the process of working on the next generation of smartphones Pixel, Google collects data for improvement of face detection. The Corporation employees go on the public major American cities and offer to do a selfie on their phone some people. Those who agreed, in return, receive a coupon for a discount of five dollars when buying in Amazon or Starbucks.

Face photos are on an unknown smartphone, hidden in a heavy case that hides the design of the device. Take in a kind of promotion, people say that they were asked to take some pictures of the face from different angles. The portal Zdnet told one of these stories: a friend of the editor, George, was engaged in relaxation practices in one of the parks of new York when he was approached by Google employees. He watched the passers-by and noticed a couple of people who looked like volunteers conducting a social survey, or as Scientologists. They addressed him with the words, “hi, we collect information to improve the function of facial recognition in future devices Google”.

Inquiring how a real engineer, George agreed. Before the actual shooting process, the data collectors asked him for his written consent to the processing of data. According to him, the mere fact of their biometrics, the IT giant does not bother him, after all, Google knows a lot of details. Face recognition for user authentication requires quick and accurate operation of complex artificial intelligence algorithms. The neural network underlying them, should be initially “trained” on a large amount of input data. Apparently, this is Google, however, it is unclear what the scale of the campaign. For effective training of recognition systems, even fairly simple images, usually require tens of thousands of images.

Previously, some companies have been caught using large databases of human faces to improve their neural networks. Despite the fact that most often it was done absolutely legally, the American public reacted to the fact that in a rather negative way. Authentication system “in the face” became the most popular method of unlocking smartphones in recent years. There are two basic approaches, differing in the complexity of implementation and level of provided security. The first and most common is a simple face recognition using a normal front-facing camera. It’s cheap, moderately demanding chipset of the smartphone, but it can be deceiving correctly made picture. The second involves the construction of maps of the user’s face, which is illuminated by infrared led. A special camera measures the distance to a few tens of key points and, in fact, know not the face, and its three-dimensional model. The reliability of this option allows Apple’s customers to use it to authorize financial transactions on smartphones.

What kind of facial recognition system will be installed in the next generation of Google Pixel is still unknown. On the one hand, according to some leaks, biometric user authentication “in the face” to have a reliable iPhone. It follows from the analysis of the beta version of Android Q, which is expected to debut together with the new smartphone from Google. In its settings discovered a number of items characteristic of a full biometric authentication, identical to that found in Apple devices. On the other hand, a well-known design concepts Pixel 4 do not imply on the front panel of any additional sensors, besides the usual camera.
