The security of bio-metric information is method of identifying a person or verifying the identity of a person based on biological characteristics. In recent years, biometric systems have assumed greater importance for information security systems. It offer reliable security, they themselves have to satisfy high security requirements to ensure authentication. Many public key algorithms such as RSA, DES and Tripple DES are concerning to construct an effective biometric security and encryption system as well. In this paper, we propose new efficient and effective mechanism for confidentiality and authentication for biometric information transmitted by using new block cipher Public key algorithm. It is an equivalent of RSA public key algorithm. It enhances the speed of encryption, decryption and authentication process. We applied this algorithm in digital signature, e-commerce and e-voting system. We bidding here, new algorithm with biometric security.
