Abstract

PURPOSE:To prevent illegal use of a copied program or data or the like by providing a specific code to identify other information processor to an information processor, storing the specific code in an external storage medium and operating a specific program by the relevant information processor only to the specific code. CONSTITUTION:A means 21 enabling to write prescribed information is provided to an external storage medium 1 to provide specific information to an information processor 2 and the write means 21 writes specific information onto the external storage medium 1. When the specific information read from the external storage medium 1 and the specific information set to the information processing unit 2 are coincident, the information processor 2 applies processing. Thus, should all cylinder areas of a floppy disk 1 be copied by the 3rd party, since other specific code is provided to other information processor although the information processor of the same specific code can make processing, no processing is applied, resulting in preventing illegal use.
