Cryptographic Protocol Depending on Biometric Authentication
In modern age, security is the most challenging issue for using the secure data used by computer. This cryptographic protocol on biometric authentication is nothing but the combination of cryptography and biometric authentication. Here, the same idea of cryptography is working (i.e. using key, conversion of plain text into cipher text called encryption and the reverse, means cipher text to plain text called decryption). Here, the most promising method fingerprint geometry of biometric authentication is used as the key for encryption and decryption.
