The principle of finger vein recognition is a kind of vein recognition. First, the personal finger vein distribution map is obtained through the finger vein recognition instrument. Based on the finger vein distribution map, A special comparison algorithm extracts feature values, obtains an image of the finger vein through an infrared D camera, stores the digital image of the finger vein in the computer system, and stores the feature value.
Finger vein recognition technology uses near-infrared rays to penetrate the vein pattern image of the finger for personal identification. It is a biometric identification technology with high precision and speed in the world. Among various biometric technologies, because it is a technology that uses the internal characteristics of living things that cannot be seen from the outside, it is attracting attention as a second-generation biometric technology with high anti-counterfeiting properties.
A typical case of the application of finger vein recognition technology abroad is that Japan has widely applied this technology to more than % of the country's M self-service withdrawal services, effectively avoiding the occurrence of financial crimes. In addition, finger vein technology has also begun large-scale commercial use in overseas markets such as the Middle East and Latin America. Most domestic security product manufacturers, such as electronic lock factories, access control factories, integrators, etc., have begun secondary development of finger vein technology and related product upgrades. , Financial institutions also apply finger vein recognition technology to banking services with relatively high security requirements, such as vault access control, quota authorization, deposits and withdrawals, etc.
At the same time, since finger vein recognition technology uses the internal characteristics of the body to identify and can only be used if the body is alive, it is a big step forward in comparison with recognition technologies such as fingerprints. (For example, fingerprints can be easily copied, imitated, and can be identified even by cutting off the finger, but the finger vein must be a living body with flowing blood, so that tragedies like the Hohhot jailbreak case will not happen.
