Abstract

PURPOSE:To attain the complete protection of copies by securing such a constitution where a specific number of an information processor stored in a ROM of this processor into a program and the program is carried out only by the information processor that has the coincidence between said specific number and a registered one. CONSTITUTION:The product number of an information processor is previously stored in a product number storing part 4 of a ROM 3 as a specific number of the processor. At the same time, the specific number, i.e., the product number of the information processor is registered at the program supplier side for a program supplied for storage into the processor. When the program supplied to a main memory 1 is loaded, a CPU 2 reads the product number out of the part 4 and collates this number with the product number registered into the program loaded to the memory 1. Then the program processing is continued when the coincidence is obtained between both product numbers. While the execution of the program is rejected when no coincidence is obtained between both product numbers. As a result, the execution is impossible for a program if copied illegally through the processors except the registered one.
