Abstract

<P>PROBLEM TO BE SOLVED: To provide a system for issuing a license key which prevents the unauthorized use of software or makes the unauthorized use difficult. <P>SOLUTION: The available period of software installation is given to the license key. Information peculiar to a PC or a device is added to the license key and is held as an internal key. Software performs collation of the internal key to permit execution. Thus damage is prevented even when the license key flows out. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

この発明は、ソフトウエアの不正利用防止を目的とするライセンスキー発行システムに関するものである。  The present invention relates to a license key issuing system for the purpose of preventing unauthorized use of software.

従来、ソフトウエアの不正利用を防止するためにライセンスキーを入力させ、チェックを行う方法が一般的に行われている。またＰＣの固有情報をサーバで取得し管理・認証する方法もある。  Conventionally, in order to prevent unauthorized use of software, a method of inputting and checking a license key is generally performed. There is also a method of acquiring, managing, and authenticating PC-specific information with a server.

しかしながら、以上の技術によれば、ライセンスキーを違法にコピーし利用された場合にその妥当性を判断するのは困難である。しかもインターネット上に流出した場合にはその被害は甚大になる。またＰＣ固有の情報をサーバで管理・認証する方法はコストと個人情報保護の観点から好ましいとはいえない。そこで、この発明は、ソフトウエアの不正利用を防止もしくは不正利用をやりにくくするライセンスキーの発行システムを提供することを課題とする。However, according to the above technique, it is difficult to determine the validity of a license key that is illegally copied and used. And if it leaks on the Internet, the damage will be enormous. Also, a method for managing and authenticating information unique to a PC by a server is not preferable from the viewpoint of cost and personal information protection. SUMMARY OF THE INVENTION An object of the present invention is to provide a license key issuing system that prevents unauthorized use of software or makes it difficult to perform unauthorized use.

以上の課題を解決するために、この発明は、
１）ソフトウエア利用許可者は仮ライセンスキーから正規ライセンスキーを発行する。
２）正規ライセンスキーにソフトウエアを特定する情報とインストールの有効期間（開始と終了）を設ける。
３）正規ライセンスキーとＰＣを特定する情報からソフトウエアは内部ライセンスキーを自動生成しＰＣ内部に保持する。
４）ソフトウエアは内部キーを照合し実行を許可する。
ことを特徴とするライセンスキー発行システムである。In order to solve the above problems, the present invention provides:
1) The software use authorized person issues a regular license key from the temporary license key.
2) Information for identifying software and an effective period (start and end) of installation are provided in the regular license key.
3) The software automatically generates an internal license key from the information for specifying the regular license key and the PC, and holds it inside the PC.
4) The software verifies the internal key and permits execution.
A license key issuing system characterized by the above.

１）インストール有効期間により正規ライセンスキーがコピーされ流失しても、有効期限外の可能性が高く不正利用を防止または困難にできる。
また、有効な開始日時もライセンスキーに含まれるので、不正にＰＣまたは機器の時刻を戻しての利用も防止できる。
２）内部ライセンスキーにより、他のＰＣまたは機器にコピーしての不正利用を防止できる。
３）仮ライセンスキーから正規ライセンスキーの発行はソフトウエアの利用許可者が行うため不正かどうかのチェック手段を講じることが可能。1) Even if the regular license key is copied and lost due to the installation valid period, it is highly possible that the valid period has expired, and unauthorized use can be prevented or difficult.
Further, since the valid start date and time is also included in the license key, it is possible to prevent use by returning the time of the PC or device illegally.
2) The internal license key can prevent unauthorized use by copying to another PC or device.
3) Since the authorized license is issued from the temporary license key by the authorized user of the software, it is possible to take measures to check whether it is fraudulent.

この発明の一実施形態を、図１に示す。
インターネット上にライセンスキー発行サーバを設け、ソフトウエア利用者が仮ライセンスキーから正規ライセンスキーを取得する。
ソフトウエア利用者はソフトウエアインストール時、もしくは初回利用時に、ＰＣに正規ライセンスキーを入力する。 ソフトウエアは正規ライセンスキーとＰＣの固有情報から内部ライセンスキーを自動生成し、内部に保持する。
ソフトウエアは毎回起動時に内部ライセンスキーを照合する。One embodiment of the present invention is shown in FIG.
A license key issuance server is provided on the Internet, and a software user acquires a regular license key from a temporary license key.
The software user inputs a regular license key to the PC at the time of software installation or first time use. The software automatically generates an internal license key from the regular license key and the unique information of the PC and holds it inside.
The software verifies the internal license key at each startup.

「実施形態の効果」
ライセンスキー発行サーバにより管理コストを最小限にすることができる。また利用者の記録を残すことで、ライセンスキー不正発行要求をモニターできる。"Effect of the embodiment"
The management cost can be minimized by the license key issuing server. In addition, by keeping a record of the user, it is possible to monitor a license key unauthorized issue request.

「他の実施形態」
