<p>PROBLEM TO BE SOLVED: To provide a program equipped with original decision function, pro gram having alteration factor and system for storing program that has decision function capable of protecting from being copied data, by deciding as if hard ware has accorded with recording medium by using identifying data of both hardware and recording medium. SOLUTION: When program saves data, specific identifying data for saving are made by combining specific hard ware identifying data that was set up in advance into a hardware practicing the program and specific memory identifying data that was set up in advance into a transportable recording medium which records the data. The data that was obtained by the program is saved into the recording medium with the identifying data for saving. When the program read data, identifying data for saving that is recorded into recording medium for reading in is decided if it will accord with combination of the identifying data for memory in the recording medium and hardware identifying data of the hardware that is used at reading in. In the case that these are not accord with, the program is limited to practice.</p> |
