Introduction of other unlocking methods

1, fingerprint identification

Low cost, simple and quick use, and relatively guaranteed safety. Fingerprint identification is naturally reserved in most thousand yuan machines and some flagship models.

In addition to the classic front fingerprint identification (the disadvantage is that it will compress the screen ratio), the popular back fingerprint identification, side fingerprint identification and off-screen fingerprint identification technologies in recent years are also relatively simple and convenient fingerprint unlocking methods.

2. Face recognition

At present, facial recognition technology is divided into 2D and 3D structured light. At present, the schemes used by mainstream flagship machine usually belong to the relatively safe 3D structured light recognition technology.

This way of unlocking is very safe. According to research statistics, the false recognition rate of face unlocking method based on 3D structured light recognition technology is only 1: 1000000, which is much safer than the traditional fingerprint recognition method of 1:50000.

3. Iris recognition

Compared with fingerprint recognition and facial recognition, iris recognition is more difficult and costly. The cool scenes such as unlocking through eye recognition, which are common in science fiction films, are all based on iris recognition technology.
