Mutual authentication system between user and system
First Claim
1. A multi-step mutual authentication system between a user and a system in which an electronic apparatus at a system management side and a terminal device at the user side are connected via a communication path and mutually authenticate a user and the electronic apparatus at the system management side as a target of access by using the system authentication information from a recording medium that is incorporated in the electronic apparatus at the system side and the personal authentication information from a personal input operation of the terminal device operated by the user,wherein two sets of a plurality of data for authentication are registered on the server, said two sets of a plurality of data consist of images, one of the sets being plural images for personal authentication indicating personal authentication information of the user, and the other set being plural images for server authentication indicating system authentication information, andthe authentication at the server side using the plural images for the server authentication is performed one by one of said plural images for server authentication and then the authentication at the user side using the plural images for the personal authentication of the user is performed one by one of said plural images for personal authentication after each one of said plural images for server authentication is performed.

Abstract
An effective means for system authentication by a user.
A system is characterized by connecting an electronic apparatus on the system management side to a terminal on the user side via a communication line including the internet and, using system authentication information recorded on a recording medium included in the electronic apparatus on the system side and personal authentication information entered through a personal input operation on a user-operated terminal, for mutual authentication between the user and the electronic apparatus on the system management side that is accessed.
In the mutual authentication system between the user and the system, two sets of authentication data are registered: one set is personal authentication data indicating the personal authentication information on the user and other set is server authentication date indicating the system authentication information.
The system is characterized in that server side authentication using the server authentication date and user side authentication using authentication data of the user are performed alternatively.
