Biometric Database Protection using Public Key Cryptography


M.ManiRoja, Sudhir Sawarkar


Vol. 13  No. 5  pp. 20-28


With the increasing need for stringent security measures in recent times, biometric systems have assumed greater importance for information security systems. For biometric systems to offer reliable security, they themselves have to satisfy high security requirements to ensure invulnerability. This paper proposes two different approaches based on RSA and Elliptic curve cryptography for database protection of biometric authentication systems. Use of K-means algorithm is also proposed for the generation of encryption and decryption keys from the biometric templates. In this paper, implementation of public key algorithms has been realized for experimental purposes and the results thus obtained have been critically verified
