<P>PROBLEM TO BE SOLVED: To provide a security system capable of accurately detecting a suspicious person for whom it was once erroneously determined as a person having a proper authorization in a monitoring area. <P>SOLUTION: The security system includes: detection means 21 for detecting a position of a person existing in a monitoring area; identification information acquisition means 22 for acquiring identification information of the person; authorization identification means 273 for determining an authorization, checking whether the person is a preregistered authorized person or an unauthorized person for each person detected; position tracking means for tracking a person through recording a history of positions for each person; and determination means for detecting a specific behavior of an unauthorized person and determining the unauthorized person as a suspicious person. When a result of an authorization determination is changed form an authorized person to an unauthorized person even once he/she was determined as an authorized person and his/her specific behavior was accepted, the determination means retroactively determines whether a history of positions stored for the person includes a specific behavior and determines the person as a suspicious person if the specific behavior is included. <P>COPYRIGHT: (C)2013,JPO&INPIT |
