User Authentication System using Base Password and Member Registration Information

Abstract

The password rules to be applied for the user account creation are often different by websites. Thus we often forget the password to sign in website and it creates waste of time for frequent password reset. In order to solve this problem we propose a new authentication method in this paper. When user forget the password to sign in, the existing methods require a password reset step but our proposed method provides new sign in scheme through the additional authentication step with base password and personal information registered at the member sign up stage. From the result of performance comparison the proposed method is considered to be more efficient than others because it provides not only an equivalent level of security with others but also requires only a half of the number of transactions and the time required for password reset step.
