Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a computer system in which system security is enhanced by preventing an unauthorized access by others and making it difficult to steal an activation code. SOLUTION: The system is constituted of a main sensing unit with a display device 1 and a sensing board surface to move when contacted by an object to be sensed 7; a sensing part 5 to sense the object to be sensed 7 moved when contacted on the sensing board surface; an image generation part 11 to generate a locus image to follow a moving locus of the object to be sensed 7 sensed by the sensing part 5; an image encryption storing part 17 to store a designated image encryption; and a control part to allow the computer system to be activated on condition that a designated image screen is displayed on the display device 1 when activated, the locus image generated by the image generation part 11 is compared with the image encryption and they turn out to be identical each other.
