<p><P>PROBLEM TO BE SOLVED: To provide a system performing authentication from a past action history of an authenticated person. <P>SOLUTION: An authentication server displays a period of action history information used as authentication information, and randomly displays each position information of an action history pattern list. The authenticated person reads the period of the action history information displayed on a screen interface, and selects an action history pattern corresponding to each the randomly displayed position information in action order according to a time series. The screen interface is displayed with an address corresponding to the position information such that the authenticated person can perform easy understanding instead of displaying the position information inside the action history information. Therefor, conversion processing from the position information to the address is performed before displaying it on the screen interface. The address corresponding to the information about a position not visited by the authenticated person within a designated period can be also displayed on the screen interface, for example, so as to prevent an accidental hit of false recognition even when another person slapdash performs input. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
