A User Authentication System Using Back-Propagation Network

Information security is a critical issue with all information systems. One of the key points in information security is user authentication. Password is widely used to authenticate a legitimate user. In conventional password authentication schemes, a server must maintain a password table that stores each user's ID and password. In order to ensure the system's security, the system has to protect the password table from being tampered with by an intruder. The method is very dangerous. In this paper, we use the technique of Back-Propagation Network to design a user authentication scheme. The proposed scheme does not store or maintain a password table and the users can freely choose their username and password. Furthermore, if any user wants to change his/her password, the system can retrain the BPN efficiently
