Cryptosystem Based On Finger Vein Patterns Using Vas Algorithm

Cryptosystems based on biometrics authentication is developing areas in the field of modernize security schemes. Elastic distortion of fingerprints is one of the major causes for false non-match. While this problem affects all fingerprint identification function it is especially dangerous in opposite identification function such as note list and reduplication function. In such function malicious possessors may purposely distort their fingerprints to evade identification. Distortion rectification or equivalently distortion field estimation is viewed as a regression problem where the input is a distorted fingerprint and the output is the distortion field. The current document deals with the application of finger veins pattern as an approach for possessor confirmation and encryption key generation. The design of the optical imprison scheme by near infrared is described. We propose a step for the location of the vein crossing points and the quantification of the angles between the vein-branches this information is used to generate a personal key that allows the possessor to encrypt information after the confirmation is approved. In order to demonstrate the potential of the suggested approach and model of figure encryption is developed. All action biometric imprison figure presetting key generation and figure encryption are performed on the identical hidden platform adding an important portability and diminishing the execution time.
