PURPOSE:To prevent an onerous program from being incorrectly used by a third person other than its purchaser by adding an inherent code to an onerous program storing medium and recording the inherent code in an information processor. CONSTITUTION:To load and execute an onerous program 1-2 to/by the information processor at first, an inherent code alpha and a history number beta added to the onerous program storing medium 1-1 are registered in a code area 5-1 by a code registering mechanism 2-1. The mechanism 2-1 registers the history number beta of the storing medium 1-1 on the position of the code area 5-1 corresponding to the inherent number alpha of the storing medium 1-1, and after registration, the inherent number alpha of the medium 1-1 and the history code beta are erased. Consequently, the storing medium 1-1 can not register the code in another information processor and the onerous program 1-2 can not be loaded by another information processor. |
