The company Amazon received a patent for identification of users on the auricles. The shape of each person’s ears, according to specialists in physiognomy, and Amazon’s engineers agree with them, is unique. It is for this reason that the company suggests using them to authenticate the user and unlock the smartphone.
According to the idea of Amazon engineers, unlocking the smartphone will happen automatically. To do this, just bring it to your ear, for example, during a phone call. The new technology will use the front camera and accelerometer, which are equipped with all modern smartphones. However, when the new method of authentication according to the shape of the auricle becomes available to ordinary users, it is not specified.
