In recent times, generating cryptographic key from biometrics has gained huge attractiveness in research community due to its superior performance in security system. Objective of this research work is to generate tough and non- repeating cryptographic keys. In this paper, we have proposed non –repeating and irrevocable cryptographic key from biometric images. The proposed cryptographic method enhances security in Multibiometric authentication system with greater exactness and is more dependable way to recognize the person. In this system, ECC is used as the cryptosystem. The Elliptic curve generation expressly generated by using Genetic Algorithm. Genetic algorithm is a class of optimization algorithm. Many tribulations can be solved using genetic algorithm through genetic process of crossover and mutation. The objective of the GA is to enhance security through non repeating key and Digital signature. The proposed cryptography system leads to protect the multibiometric template and also provide authentication from irrevocable and nonrepeating key.
