A secure cryptosystem from palm vein biometrics

This paper proposes a novel technique to generate an irrevocable cryptographic key from the biometric template. The biometric trait considered here is the palm vein. The technique proposed here utilises the minutiae features extracted from the pattern generated. The features include bifurcation points and ending points. Since other cryptographic keys are probable to theft or guess, keys generated from the biometric entity are more preferable as these biometric keys are attached with the user. Minutiae patterns generated from the palm vein are converted to cancelable templates which in turn are used for irrevocable key generation.
