Secured crypto-biometric system based on session key navigation

Cryptography is mainly used in security systems to protect information. It is possible to access the information by the unauthorized persons for different purpose during data transmission over networks. So, it needs to apply preventive and or corrective actions for the enterprise computer network from the intruders for improving the security. The proposed system combines biometrie and cryptography is to gain much attention [1]. Finger-knuckle-print is a unique feature to every individual i.e., bending surface of the knuckle portion is highly unique in progress. It proves to be more secure. In such system, a constant key is generated from user´s biometric sample and a link has been established between the user identification and the cryptographic systems [1]. This system takes Multi-Instance user´s samples for identification purpose. For each instance, this system generates a session key randomly. The session keys are generated by using Random Triangle Hashing method (sender´s biometric) [15]. Those generated keys are being protected by Shuffling process, which is used to hide the messages by using the concepts of symmetric cryptography.
