[0007]

In a conventional security protection device using a portable security input device, the operation of the portable security input device requires only pressing one button. Therefore, in the event that the portable security input device is stolen, there is a problem that the portable security input device can be operated by anyone other than the correct user. That is, since the portable security input device has only one button, it is not possible to enhance security by operating the portable security input device and take measures against theft.

Further, since the infrared light is emitted only in one direction from the portable security input device to the main unit, the source of the infrared light cannot be confirmed. Therefore, if the infrared light is analyzed and the infrared light is transmitted by any method without using the portable security input device, the main unit will determine that the portable security input device is correct. There was a problem of misrecognition. The present invention has been made in order to solve the above problems, and when the portable security input device is stolen,
Alternatively, it is another object of the present invention to provide an information processing system capable of ensuring security of use of the information processing system even if the ID of the portable security input device is known.
