However, when he logged into the Internet bank via Face ID, it turned out that his account was hacked and 4,000 euros were withdrawn.

The bank reportedly informed him of this. Then the businessman logged into his account again via Face ID to see what was happening, but everything was confirmed – the money was gone. The businessman sued all the perpetrators, the matter came to the Volosskaya prosecutor’s office, which demanded a preliminary check. The incident is being investigated.

Reference. What is Apple Face ID and True Depth Camera
In a nutshell, Apple Face ID is a system that uses facial recognition to unlock your smartphone and confirm payments. It compares the user’s face with the picture stored in the iPhone’s memory. And makes these pictures Phone X using a special camera True Depth Camera.

At the top of the front of the iPhone X there is a small island, not covered by a huge display and stuffed to capacity with various electronics and sensors. In addition to the usual set (front camera, microphone, speaker, proximity and light sensors), there is an infrared camera, a backlight system (flood illuminator) and a dot projector (dot projector).
In fact, True Depth Camera consists of them. It creates a 3D snapshot of your face, and when you log in, it matches your face with the snapshot. Here’s how it works.

The backlight system is needed so that the camera can take better photos in low light conditions. The dot projector projects 30,000 invisible infrared dots onto your face, and the infrared camera takes pictures of you along with these dots. They are needed to highlight the characteristic features of your face, and together they form a kind of 3D map. When you first set up Face ID, you’ll be asked to move your head slightly so that iPhone X remembers what your face looks like from different angles.

After that, every time you try to use Face ID, the True Depth camera will take a picture. If your facial features match the 3D map stored in your phone’s memory enough, you’ll be considered a legitimate user, meaning you’ll be allowed to sign in or confirm your Apple Pay payment. If the match level is insufficient, you will be prompted to try again. The sequence and logic of work here are exactly the same as in the case of a fingerprint scanner, however, with one important difference.

Apple has built a special coprocessor into the smartphone, optimized for machine learning algorithms. With its help, the system will get to know you better over time – that is, firstly, the farther, the faster it will recognize you, and secondly, changes in hairstyles, facial expressions or accessories will not confuse it. Apple says the system will recognize you even if you wear a scarf or grow a beard.
