Abstract

PURPOSE:To prevent the surreptitious use of a program effectively by providing a key device, which outputs a characteristic key signal expressed by the function of a serial key operation signal, to the main part of the program performing key processing operation. CONSTITUTION:As a key operation signal from a key operation signal means 1a is inputted, a key device 6 reads out information from a specific address (key address) to output a signal (key signal) prescribed by a specific function using a previously received key operation signal as a variable. Then, this key signal is processed by the key signal processing means of a CPU1 and when a prescribed key signal that a program generating person knowns is not obtained, the principal operation of the program is placed in an abnormal state. The key device 6 is equipped by utilizing the auxiliary socket of an ROM or RAM to prevent the surreptitious use of the program without modifying hardware.
