Abstract
A computer providing a trace image booting password to control access to the computer. The computer includes a sensing plane; a sensor unit sensing a moving sensed unit contacting the sensing plane; an image generator generating a trace image along the movement of the sensed unit as sensed by the sensor unit; and an image storage storing a predetermined image password based upon a predetermined image. The computer further comprises a controller displaying the predetermined image on a display screen at a booting time of the computer to allow a user to move the sensed unit in contact with the sensing plane over the displayed predetermined image, comparing a trace image generated by the image generator along the moving trace of the sensed unit by the user with the stored image password, and booting the computer if the generated trace image corresponds to the stored image password.
