  • Patent number: 8572703
    Abstract: A system and method for authenticating a user of an image processing system. User credentials are received at an authentication device corresponding to an image processing device, and transmitted to a first server remote from the authentication device. The validity of the user credentials are judged by comparing the received user credentials to authentication information stored at the first server, and a result of the judging is transmitted to the image processing device. The image processing device then requests access to a second server remote from the image processing device, and the second server transmits a request for the user credentials to the first server. After receiving the user credentials from the first server, the second server performs user authentication.
