PROBLEM TO BE SOLVED: To provide a low cost security system which can decide whether a photographed moving object is an intruder accurately and actuate a notifying means, only if the object is an intruder. SOLUTION: The security system is composed of a monitoring camera 51 takes photographs of a moving object and outputs it as animation data; a frame stripping off means 54 inputs the animation data and divide it into frame images with a certain time interval; a conversion means 58 decides whether two frame images separated in turn have any change on the image by pixel and transforms the frame image into numerical string data, on the basis of determined results; a code-generating means 59 generates geometrical codes, corresponding to a shape profile of the moving object, on the basis of the numerical string data, a deciding means 63 decides whether the moving object is a human being, on the basis of the geometrical codes; and an notification control means. The notification control means actuates a notifying means, when the moving object is decided as being a human being. COPYRIGHT: (C)2005,JPO&NCIPI
