Abstract: Multi-biometric system provides very important and secured methodology for enhancing the security level of information technology. The uniqueness of biometrics for any specific human being makes the identification system more secure.The traditional cryptosystem suffers from several problems such as key management, key privacy. Combining cryptography with biometrics removes such kind of problems and used for key generation. Here key may be generated by using two or more biometric factors.
