本発明はコンピュータシステムにおけるプログラム保護
方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program protection method in a computer system.
従来、プログラムの保護は、有償プログラムを使用する

ックしてプログラムの使用の可否をチェックすることに
よって行っている。Traditionally, program protection has been done by storing the program in the library of the contracted system when signing a contract to use a paid program, setting a flag on the stored program to indicate that the contract has been signed, and checking the flag when using the program. This is done by checking whether the program can be used.
また、外部記憶媒体上にシステム固有の識別詞（以下シ
ステム識別詞と記す）を設け、有償プログラムの契約時

ることにより使用の可否をチェックする方式もある。In addition, a system identifier unique to the system (hereinafter referred to as system identifier) is provided on the external storage medium, and the system identifier is set in the program when contracting for a paid program, and the system identifier is set on the external storage medium when the program is used. There is also a method of checking whether the program can be used by checking the identifier and the system identifier set in the program.

。In the conventional program protection method described above, if you copy a contracted program or copy a paid program for each external storage medium (for example, each system disk) that has a system identifier set, and take it to another system, you will not be charged a fee. The drawback was that it could be used illegally without a contract.

ク手段とを含む事を特徴とする。The program protection method of the present invention is a protection method for paid programs provided by manufacturers of computer systems, in which an identifier unique to the computer system is stored in an internal storage section installed in the computer whose contents are retained by a battery or the like even when the power is turned off. system identifier setting means for setting the identifier in advance in a program with which a usage contract has been made; and a paid identifier setting means for setting the identifier in the program with which the program has been contracted for use; The present invention is characterized in that it includes a paid program usability checking means that checks whether the identifiers set in the program match, and if they match, the paid program is usable, and if they do not match, it is disabled.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の構成を表す図であり、本実施例はシス
テム識別詞設定手段１．有償識別詞設定手段２及び有償
プログラム使用可否チェック手段３より構成される。FIG. 1 is a diagram showing the configuration of the present invention, and the present embodiment shows system identifier setting means 1. It is composed of a paid identifier setting means 2 and a paid program usability checking means 3.

別詞を設定する。When the computer 100 is installed by the manufacturer at the user, the manufacturer's operator operates the keyboard display 10 and uses the system identifier setting means 1 to ensure that the memory contents are retained by the battery even if the power inside the computer 100 is turned off. A system identifier for system identification unique to the user is set in the storage unit 101.

を有償識別詞２０１として設定する。When the user requests the manufacturer to purchase a paid program because he wants to use it, the manufacturer's operator displays the requested program 2 from the keyboard display 20.
00, the user's identifier is set as the paid identifier 201 by the paid identifier setting means 2.

、プログラム２００を保護する。When the program 200 to which this paid identifier is set is attempted to be used in response to an instruction from the user, the paid program usability check means 3 operates, and the program 200 is used with the identifier 101 of the computer 100 that is about to be used. Paid identifier 2 of program 200
01 are compared, and if they match, use of the program 200 is permitted, and if they do not match, use is denied, thereby protecting the program 200.
