Abstract: In a world that is more digitally connected than ever before faces an inevitable problem of securing our most integrated data and message. Currently, Voice over Internet Protocol (VoIP) becomes one of the most dominant and attracting technologies in the world of telecommunications. The chief problem is to protect our data in a unique way that could only be worked upon by the sender and the recipient. Using biometric we can generate an exclusive key that will be unique for each and every individual. Here we propose to make a mutual contribution of the participants (sender and receiver) to share their biometrics to have very secured VoIP communication. After generating the keys from the irises of the two participants, this will be combined with the pseudo random numbers, to produce a strong encryption keys. And the resulting key can be used for encrypting our message. This method is proposed because even if one the iris biometric is stolen, the attacker cant access the data unless the data encrypted with multimodal biometric key. And for more security Therefore billions of unique keys can be generated, making VoIP technology hard for an attacker to guess the key. This key act as a symmetric key for both encryption and decryption. This proposed system is composed of two modules 1) Feature extraction of Iris 2) Cryptographic key generation. 3) Fusion of iris 4) Fusion of PNRG with Fused iris key.
