Abstract:
PURPOSE: To suppress the unauthorized use of software without impairing spatial convenience when the software is used.
CONSTITUTION: The storage medium parts 2, 3 for management on which various kinds of regulation information(requirement limit quantity I for software, the number L of next hierarchy generation limit the number of hierarchy step K representing to what hierarchy backup version for its own can be generated, and software identification information PID, etc.) are written and a software storage medium part 1 in which the software is stored are set in one pair, and the use of the software can be permitted under the restriction of such regulation information. Also, the software storage part 1 may be set same as the storage medium parts 2, 3 for management, which enables them to be set as separate storage medium parts. When a separation managing system as in the latter case is employed, the execution of the software is prohibited until the software identification information PID written on the medium respectively coincides with each other.
