IMAGE PROCESSING APPARATUS AUTHENTICATION SYSTEM AND IMAGE PROCESSING APPARATUS

摘要

An image processing apparatus serving as a master device and a plurality of local image processing apparatus serving as local devices are connected to one another via a network, and each of the devices includes an authentication information storage unit and an authentication unit. The master device stores, as master authentication information, authentication information necessary for an authentication on each of users who are able to use each of the devices, for each of the devices, and allows editing of the master authentication information. When the authentication information on the local device in the master authentication information is edited, the edited authentication information is transmitted to the local device, and the authentication information stored in local device is updated. When a user login operation is performed on the local device, an authentication is performed by using the authentication information in the local device.

主权项

1. An image processing apparatus authentication system comprising:
a plurality of image processing apparatuses connected to one another via a network, each of the image processing apparatuses including: a user identification information input unit that receives user identification information; an authentication information storage unit that stores therein authentication information necessary for authentication on the user identification information; and an authentication unit that performs the authentication on the user identification information received by the user identification information input unit, based on the authentication information stored in the authentication information storage unit, wherein one of the image processing apparatuses serves as a master device and the other image processing apparatuses serve as local devices, the master device and all of the local devices are able to communicate with one another, the authentication information storage unit of the master device stores, as master authentication information, authentication information necessary for the authentication on the user identification information on each of users who are able to use the image processing apparatuses, for each of the image processing apparatuses, the master device includes:
an authentication information editing unit that edits the master authentication information; andan authentication information transmitting unit that, when the authentication information editing unit edits authentication information on the local device in the master authentication information, transmits the edited authentication information to the local device, and each of the local devices includes:
an authentication information receiving unit that receives the authentication information from the master device; andan authentication information updating unit that performs an update of the authentication information stored in the authentication information storage unit of the local device with the authentication information received by the authentication information receiving unit.
