Abstract:
1. A user authentication control device, which controls an authentication effective period for a user authentication device of a data processing device connected with a sever device through a network, the user authentication control device used for user authentication comprising: a control unit including a central processing unit (CPU); a bandwidth acquiring unit, executed by the control unit, that acquires a communication speed of the network; and an effective period determining unit that: determines an authentication effective period based on the communication speed and on the significance of one of the server device and the data stored in the server device; and changes a coefficient based on the significance of one of the server device and the data stored in the server device, wherein the coefficient is set to small to make the upper limit of a transferable data amount in one authentication, when one of the server device and the data stored in the server device is important, and the coefficient is set to large to make an authentication interval longer, when the significance of one of the server device and the data stored in the server device is low.
