Multi-Modal Crypto-Biometric System Based On Session Key Navigation for Secure Transaction

Cryptography is the science of keeping secrets. It is mainly related to data security when transmitting data over networks. During data transmission intruders may possible to acquire information without the knowledge of sender and receiver. So it needs some mechanism to prevent unauthorized access. The security system deals with Multi-Modal biometric features namely Finger-Knuckle-Print and Finger Print for recognition and verification. This approach proves to be more secure. For every transaction, random key will be generates from the user’s samples and it could be highly distinct. Random Triangle Hashing method is used for random key generation [15]. Shuffling process is used for key management and reliable transaction. This system keeping secret the content of information from unauthorized parties, detecting the alteration of data, identifying data origin and preventing an entity from denying previous actions.
