Design and implementation of identity authentication system based on fingerprint recognition and cryptography

A new scheme based on fingerprint recognition and cryptography technology is proposed. The scheme verifies the user's identity using the unique, reliable and stable fingerprint information, and realizes identity authentication to “person”. It provides the design and implementation of user register and authentication, encrypts some important information using MD5, and realizes the double authentication, which includes username/password and fingerprint recognition. The testing results show it is more available, reliable and secure.
