<P>PROBLEM TO BE SOLVED: To provide a device with authentication function and a security system, capable of preventing "spoofing" by an unauthorized user. <P>SOLUTION: Individual authentication by a user includes entrance authentication to a room, authentication input (log-in, log-out) for use of equipment, and the like. Since at least a moving time is needed until the user performs authentication input through a device at another point after authentication input at a certain point, authentication input by the user (the same user) in another place is prohibited within the moving time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
