<P>PROBLEM TO BE SOLVED: To provide a mechanism in the field of process monitor control systems which can improve security by preventing impersonation at the time of user authentication but does not burden a user. <P>SOLUTION: An operation monitor console 10 has a mechanism 16 for acquiring location information of the operation monitor console 10 and portable terminals 36, 38, and the portable terminal 38 has mechanisms 40, 42 for acquiring biometrics information. The process monitor control system transmits the biometrics information to the operation monitor console 10, verifies biometrics, determines whether the difference between the location information of the operation monitor console 10 and that of the portable terminal 38 is within tolerance or not, permits login only if the biometrics match each other and the location information is within the tolerance, acquires location information of the portable terminals at a fixed interval after the login, and performs automatic logout when the location information of the operation monitor console and the portable terminals is out of the tolerance a fixed number of times or more in succession. <P>COPYRIGHT: (C)2013,JPO&INPIT |
