Abstract
In this paper a high degree of accuracy coupled with enhanced security 128 bit hybrid cryptographic key is generated. This key is generated by considering more than one biometric template. Then to increase the security further, it is fused with an binding key, using the fuzzy commitment scheme. Brute force attack is applied to steal the key which is used for encryption by the hackers. The hybrid key that is generated from the multimodal biometric and further fused with the binding key has high randomness than other generated keys and so it has less possibility of cracking by the brute force attack. The proposed hybrid key is more random when compared to other keys in the frequency test by 5.21%, and the frequency test for blocks by 0.2% and in the overlapping and non overlapping tests by 30%.
