This paper proposed a Biometric-Crypto system which generates a cryptographic key from the fingerprints for Encrypting and decrypting the voice data packets for VoIP Security. If VoIP packets traverse the Internet to reach a destination, a number of attackers have a shot at voice data. The calls are also vulnerable to hijacking or a man in the middle attack. In such a scenario, an attacker would intercept a connection and modify call parameters. This is an especially scary attack, since the participants likely wouldn't notice a change. The ramifications include spoofing or identity theft and call redirection, making data integrity a major risk.
