BIOMETRIC AUTHENTICATION USING PARTIAL HIERARCHICAL VISU A L CRYPTOGR A PHY

The importance of a strong authentication is very crucial in almost all applications now. User authentication is a method in which the identity of the individual is verifie d for accessing certain information .Using biometric information for authentication will be a better proposal as biometric information will be unique for each individuals. The project proposes to implement a signature based authentication using partial hie rarchical visual cryptography. Visual cryptography encrypts secret information into different portions known as shares. Hierarchical visual cryptography encrypts the signature in different levels.
