Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described based on the drawings. As the device with authentication function of the present invention, a digital multifunction machine having multiple functions is taken as an example for explanation, but the present invention is not limited to a multifunction machine for digital image processing, or a printer, copier, scanner, and facsimile machine (FAX). It is also applicable to various image processing devices such as single-function computers such as computers, information processing devices represented by computers, etc., as long as it has an authentication function and a communication function with an external device.

[0030] FIG. 1 is a diagram showing an example of a system configuration including a digital multifunction peripheral according to an embodiment of the present invention and external connection devices connected to the digital multifunction peripheral via a network.

[0031] In FIG. 1, 1 is a ...

Abstract

The place where a user performs personal authentication includes a room into which entry is authenticated, and an apparatus for use of which authentication input (login and logout) is performed. In such situation, it will take at least a moving time for a user to perform authentication input at a certain location and thereafter to perform authentication input at another apparatus of a different location. Therefore, the present invention provides an authentication-capable apparatus whereby the authentication input by the aforementioned user (the same user) at a different place is inhibited within the aforementioned moving time, thereby preventing 'spoofing' by an unauthorized user.

Description

technical field [0001] The present invention relates to a device with an authentication function capable of authenticating a user. Background technique [0002] As such a device with an authentication function, Japanese Unexamined Patent Application Publication No. 11-174920 discloses a digital copying machine, which judges that when a predetermined reference time has elapsed after a key card (key card) has been installed. The set key fob is left in place for an extended period of time, rendering the key fob invalid and temporarily disabling its use. [0003] In this Japanese Patent Application Laid-Open No. 11-174920, not only the authenticated user but also other people can use it within the reference time, so there is a possibility of illegal use by others. [0004] In order to prevent such illegal use, Japanese Patent Application Laid-Open No. 2006-71684 discloses a device with an authentication function in which an ID input or a key fob is installed, and when the authe...
