Abstract

PURPOSE:To protect a right of a program, by checking a general-purpose program which is used for other device than that which has a device number designated in advance, and generating an available code in case of coincidence of the device number. CONSTITUTION:A device number ID of a medium to which a program operation is to be recognized is inputted from a keyboard 11, a program is read by a module 14, its program is edited to a 1 byte unit, and the contents are changed. Subsequently, when decoding, an encoded program 21 is read at 22 from a device medium, also a device number ID23 in a device is read by a reader 24, and the program is reedited to a 1 byte unit in accordance with said ID. Validity of a program or data, decoded in this way is checked by a check module 28, and an available code is generated by recognizing a specific device, by the information processing device. Also, in case when it has been recognized to be other device, use of a program or data on said device is made unavailable.
