An information processing apparatus and an authentication method performed using the information processing apparatus are provided. An information processing apparatus receives, as authentication information, identification information of a user of an information processing system including the information processing apparatus and an authentication apparatus, converts the authentication information, and controls to execute an authentication process based on the authentication information. The information processing apparatus converts the authentication information to form a readable authentication information by converting a character that cannot be interpreted by the information processing apparatus into a character that can be interpreted by the information processing apparatus. The information processing apparatus executes the authentication process to enable use of the information processing apparatus based on the readable authentication information, when the authentication process to enable use of the information processing system is executed by the authentication apparatus.

Information processing apparatus and authentication method using the information processing apparatus

An operating apparatus stores user information including authentication information of users permitted to use a process-carrying-out apparatus; acquires authentication information of a user of the process-carrying-out apparatus; in response, returns a state of the process-carrying-out apparatus from a power saving state into a normal state to carry out a process; carries out authentication of the user based on the authentication information of the user and the stored user information; if the authentication is not successful, requests the process-carrying-out apparatus to carry out authentication the user; if any authentication is successful, permits the use of the process-carrying-out apparatus; and, if the use of the process-carrying-out apparatus is permitted, stores the authentication information of the permitted user.

Authentication system, operating apparatus, and authentication method

An authentication system includes an apparatus and an authentication apparatus configured to perform authentication of a user of the apparatus. The apparatus includes an identification information obtaining unit configured to obtain identification information of the user and an authentication requesting unit configured to send the obtained identification information and group information indicating a group to which the user belongs to the authentication apparatus to request authentication of the user. The authentication apparatus includes an authentication unit configured to search records of identification information associated with the group information to find matching identification information matching the obtained identification information of the user.
