Secure voice over internet protocol(VoIP) network with biometric key

In a world that is more digitally connected than ever before, keeping your personal data safe is essential. Currently, Voice over Internet Protocol (VoIP) becomes one of the most dominant and attracting technologies in the world of telecommunications. The two major issues in VoIP is to be consider are that, the confidential data falling in the hands of network attackers and remembering of long cryptographic keys. Here we propose to generate a biometric key using iris, which is the combination of the iris code and the pseudo random numbers as a key for VoIP Communication. This iris key act as a symmetric key for both encryption and decryption. Unfortunately if the iris biometric is stolen, this makes the attacker to access the data if the data encrypted with biometric key alone. To overcome this problem we propose to use pseudo random numbers, which is fused with iris biometric. Therefore billions of unique keys can be generated, making VoIP technology hard for an attacker to guess the key. This proposed system is composed of two modules 1)Feature extraction of Iris 2)Cryptographic key generation.
