Independently both biometrics and cryptography play a vital role in the field of security. A blend of these two technologies can produce a high level security system, known as crypto biometric system that assists the cryptography system to encrypt and decrypt the messages using bio templates. Digital signatures require crisp keys, but due to noise bio templates produce only fuzzy data. Also biometric data are not secret. This gap can be easily filled up by iris textures as bio metric templates. They are less prone to noise when compared to other bio templates and also their unique texture give rise to high level security. Biometric keys are prone to random noises. Cryptographic systems accept some fuzziness regarding witness i.e., it must be decrypted by a key that is nearer to encryption key. The advantages of cryptography and iris based authentication can be utilized in this biometric systems.
