A novel and efficient technique to generate secured biometric key using cryptography

This paper proposes a novel methodology to generate efficient and secured key by using cryptographic techniques for the shared data to be secure. Conventional techniques depend on biometric features like face, fingerprint, iris, signature, hand geometry, keystroke, voice and the like for the extraction of key information. If a Biometric Key is lost or stolen, it is lost forever and perhaps for every application where the biometric is used, because a biometric is enduringly linked with a user and cannot be changed. In this paper we propose a technique to produce secured and efficient key from fingerprint so as to surmount these problems. The exibility and dependability of cryptography is enhanced with the utilization of cancellable biometric features. There are several biometric systems in existence that deal with cryptography. We propose a new approach which uses the features of finger print and RSA-2 algorithm to generate Cryptographic Key.
