<p>There is provided a security system for creating a usable/unusable condition of a personal computer by a more simple method. A computer includes an input device (1), a storage device (2), a processing device (3), and an output device (4). The storage device (2) contains data indicating a unique numeric value assigned to a mobile telephone KT to be connected to the computer. When the telephone KT is connected to the computer, a calculation device (3b) of the processing device checks whether the unique numeric value data is satisfied by the AND with the unique numeric value of the storage device (2). If the condition is satisfied, a control device (3a) of the processing device (3) maintains the input device (4) or the output device in the operation state and when the connection of the telephone KT is cut off and the AND condition is not satisfied, at least the input device (1) or the output device (4) is switched to the non-operation state.</p> |
