PROPOSEDSYSTEM. The proposed system is aims at designing a challenging anonymous two-factor (2f) authentication scheme. The 2f authentication is the most effective password authentication system in distributed systems. A general smart card-based authentication involves a single remote server with a set of users. 2f authentication which does not store any sensitive information on the server than the common password is the key advantage which stores information to the password table on the server. The entire system will get collapsed when the tab le gets leaked. Since no password is stored on the server it prevents security breach of millions of user’s identities stored in the server. A new set of design goals is developed for fairevaluation of this type scheme. 2f authentication addresses the threats in security and opens another interesting problem that password-based authentication protocol sexist on secure smart cards and the communication with server is not required for the password change mechanism. The users may have some changes in the prominent phases like password change, registration, authentication and revocation and eviction as supplementary phases. In the registration phase, a smart card will be issued to the user after submitting some sensitive information to the server that will be used later for the authentication purpose. This process will be repeated only when the user wishes to register again. During the smart card login process the user identity and sensitive information’s will be secured.
