CONSTITUTION: A computer security device with a built-in/out keyboard including a RF-card, which has a certain ID within, a RF-card recognition device and a security control part, consists of memories. At first, the security controller registers the ID of a user. When the device executes the security action, any input value, which is done by the keyboard or the mouse, cannot be accepted. By removing the RF card from the RF recognition device, the security action can be started, but if the user has the RF card on his body, only by leaving from his desk more than the fixed distance, the security action can be started.
