In terms of security and applicability, each technology has its own advantages and disadvantages.
The most common fingerprint unlocking methods are divided into optical fingerprint unlocking and semiconductor fingerprint unlocking. Optical fingerprint heads use optical reactions to image fingerprints, while semiconductors use potential differences to image fingerprints. The latter is for living body recognition, and fingerprints are not easy to be detected. Copy, so more security
The basic principle of face recognition technology is based on the complexity of facial features, such as the relative positions of eyes, nose, mouth and other parts, scanning and learning the multi-point parameters of the face, and then converting them into digital templates.
Finger vein recognition technology is one of the relatively high security recognition technologies at present. Its basic principle is to use the structure of vein blood vessels for identification. Because there are many dense blood vessels at the end of the fingertips, there is almost no duplication between people. , will not be unrecognizable due to abnormal skin on the surface of the finger.
