Title: Method for preventing unauthorized use of software
Inventor: ONODERA NOBUYUKI
IPC: G06F21/62
Filed: 1988-04-13
Abstract: PURPOSE:To prevent an unfairly copied software from being used with other device by comparing a central processing unit inherent identification number recorded at the central processing unit and an executable central processing unit inherent identification number held at a software. CONSTITUTION:When the execution request of a software 2 to protect a copyright is received, an operating system 5 fetches an executable central processing unit inherent identification number out of execution permitting information 1 of the software 2.
