Finger vein recognition

Abstract

Vein based biometrics are gaining importance due to their greater accuracy and security. Finger vein based biometric systems elegantly address problems present in fingerprint systems. The vein based authentication system is a promising biometric pattern for personal identification in terms of its security and convenience. The vein patterns can only be taken from a live body. Hence it is a natural and convincing proof that the subject whose veins are successfully captured is alive. Finger vein recognition technique is enhanced using neighborhood elimination technique to reduce the repeated feature set in the extracted finger vein minutiae image. Neighborhood elimination technique is employed for the purpose of removing the redundant information while keeping the effective source information for subsequent processing.
