1. The principle of the security expert vein authentication system is to match the vein pattern of the internal vein of the finger. Because the venous blood vessels are hidden inside the fingers, it is extremely difficult to copy and steal, and this method is safer than other technologies that use human body's in vitro features for authentication. At the same time, venous authentication can sense the blood flow and blood pressure in the finger and can perform the biometric detection at the same time during the identification process.
2. The high accuracy sampling sample is inside the human body, so the external interference during the matching process is very small. The accuracy of finger vein authentication is very high. According to strict medical certification and mathematical statistics, the FRR (false positive rate) is less than 0.01%, the FAR (false recognition rate) is less than 0.0001%, and the FTE (login failure) is 0%.
3. Uniqueness According to medical evidence, the distribution of finger veins between different people is completely different. The distribution of veins in the left and right hands is also different. Even if it is the same finger of a twin, the distribution of veins is also different. Moreover, the distribution of finger veins does not change in adulthood. For minors, when their finger veins change with age, it only takes 30 seconds to complete the re-registration.
4. Non-contact Relative to certain biometric technologies, finger vein recognition technology is non-contact and will be more hygienic in public places.
5. Small sample files Because the venous blood vessels of the fingers are relatively stable and easy to photograph, it is possible to achieve sampling requirements using a low-resolution camera. The venous template file thus generated is small and the matching speed is fast.
