Finger vein authentication is a technique that uses images of finger vein patterns captured by penetrating the finger with near infra-red rays to verify an individual’s identity. Delivering groundbreaking levels of accuracy and speed of authentication, this technology is one of the world’s most advanced authentication technologies.
Finger vein authentication is the only biometric identification system to use an in_vivo body characteristic that is invisible externally. It is therefore attracting attention as an next-generation biometric authentication system that is highly impervious to falsification and impersonation.
How Finger Vein Works
Finger vein authentication uses leading-edge light transmission technology to undergo pattern-matching and authentication. Near-infrared light is transmitted through the finger and partially absorbed by hemoglobin in the veins to capture a unique finger vein pattern profile, which is then matched with a pre-registered profile to verify individual identity.
Rates for acceptance of false users or rejection of true users are among the lowest for biometric technologies, making finger vein authentication a reliable security solution. Unique vein patterns plus leading-edge technology means high accuracy rates (very low FTE, FRR and FAR). Small amount of data is required (400 bytes), allowing fast authentication (< 1 second) and increased portability.
Vein pattern matching is completed within the blink of an eye, affording users a speedy authentication experience without the hassle and without the wait.
As finger vein patterns are found internally within the body, forgery is extremely difficult. Dryness or roughness on the surface of the skin also has no effect on the accuracy of vein pattern authentication.
Finger vein authentication devices are compact and therefore applicable as embedded devices in a variety of applications.
Veins are inside the body, invisible to the eye, and not accessible. Therefore, it is extremely difficult to forge and impossible to manipulate. The use of light transmission to gather biometric data means that the condition of the skin surface does not affect accurate processing.
The vein patterns of each finger are unique, so each individual can register multiple fingers as “back-up” for authentication purposes. Registration is possible even for sweaty, oily or dirty fingers
