USER AUTHENTICATION SYSTEM AND METHOD USING PERSONAL IDENTIFICATION NUMBER
First Claim
1. A user authentication system using a personal identification number, comprising:
- a user terminal device for requesting issuance of a personal identification number from an authentication server, storing and displaying a personal identification number issued by the authentication server, and registering reference information used to permit verification of validity of the personal identification number on the authentication server;
an inquiry device for requesting verification of validity of the personal identification number from the authentication server and thereafter receiving and displaying results of the verification; and
an authentication server for storing issuance information while issuing the personal identification number in response to a request of the user terminal device, determining whether to permit the verification of the validity of the personal identification number, based on results of a comparison between the information received from the inquiry device and the reference information if the inquiry device requests the verification of the validity, and replying with results of the verification based on the results of a comparison between the personal identification number received from the inquiry device and the issuance information if it is determined that the verification of the validity is to be permitted.
