Bio-key generation for integrity checking using elliptic curves in fingerprint verification system

Abstract

This paper proposes a Bio-key generation method for integrity checking in fingerprint verification system. A major drawback in traditional cryptography is random key generation and those keys need to be remembered by the user. To overcome such drawback the crypto-Bio-key generation system is introduced. In this system, there are three process to follow. Initially, a revocable transformation of the compressed fingerprint feature data using transformation key for security enhancement. Secondly, the key exchange technique using Elliptic curve cryptography (ECC) to generate secret key. Finally SHA256 hash function generates the Bio-key for high level integrity checking.
