Biometric Based User Authentication Using Smart Card

Remote user authentication is one of the major issues in the rapid growing internet era. In this paper we propose a biometric based remote user authentication scheme using smart cards. The existing methods failed to be safe in remote user authentication as the secret values in either end of the communication could be guessed by the intruder. In our scheme we introduce an addition security at the user side as an extra once by which the intruders will be unable to guess the users secret data. Hence our proposed scheme proves to provide a strong authentication and non-repudiation even in an insecure communication by sending and receiving messages with timestamps.
