Abstract |
|
Hand geometry is a biometric trait which identifies and recognizes an individual based on the shape of their hand. Cryptography involves the scrambling the message to provide security. Combining the hand geometry biometric trait and cryptographic system provides more security. The proposed system generates cryptographic key from the hand geometric biometric trait. So that the user does not need to remember the key, password etc. The proposed system makes the use of extracted biometric trait of hand geometry for generating the key. The acquired hand image is pre-processed and represented as 12 nodes undirected completely connected graph and 64 bit key is generated from the spectral properties of the adjacency matrix of the graph. Key generation module generates 64 bit key which is used for encryption and decryption of message using the DES algorithm. |
