Abstract

[Problem] A hashing-type illicit access prevention policy that uses a hashing-type cloud server can be used with a type of cloud server handling data for which data is already known, but such a policy cannot be used with a cloud server of a type wherein new data is written. [Solution] When new data has been written, the present invention: creates a unique ID for said data; stores the data and the ID in an intranet data storage device on an intranet; and deletes the data from a data storage device on the Internet, leaving only the ID. Thus, the present invention provides a data structure that can be handled by a hashing-type cloud server.

Description

入力されるデータをイントラに格納してしまう安全なクラウドサーバーA secure cloud server that stores incoming data in the intra
　本発明は、クラウドサーバーを使ったシステムに関するもので、クラウドサーバーに入力されるデータを不正アクセスから保護するための方法である。 The present invention relates to a system using a cloud server, and is a method for protecting data input to the cloud server from unauthorized access.
　業務の効率化など社会の変化に伴い、社内と社外との間の連絡・ドキュメント送付・申請・届け・報告等の手段として、Ｗebを使ったファイヤーウォール越しの外部コミュニケーションツールの利用が注目されている。 Due to social changes such as operational efficiency, the use of external communication tools over the firewall using Web is attracting attention as a means of communication, document sending, application, delivery, reporting, etc. between inside and outside the company. Yes.
　しかし、外部コミュニケーションツールでは、外部からアクセスできるようにインターネット上のサーバーを使用するが、この外部コミュニケーションツールに入力されるデータもインターネット上に格納されるので、不正アクセスに対するセキュリティが弱いと言う欠点がある。 However, the external communication tool uses a server on the Internet so that it can be accessed from the outside. However, since the data input to the external communication tool is also stored on the Internet, there is a drawback that security against unauthorized access is weak. is there.
　これまで多くの研究者や開発者が不正アクセスからインターネット上のデータを保護する方法として、暗号化や分割化又は分散化などデータそのものを加工する方式や、パスワードや電子証明書などデータへのアクセス権限をコントロールする方式等の方法を考案してきた。 Many researchers and developers have been able to protect data on the Internet from unauthorized access by processing data itself such as encryption, partitioning, or decentralization, and access to data such as passwords and electronic certificates. I have devised a method of controlling authority.
　しかし、これらの従来型不正アクセス防止策は、技術が日進月歩する中、不正アクセスを行おうとする者との知恵比べになっており、データがインターネットにある以上は、データの不正アクセス防止策が何時破られるか分からず、不正アクセスの不安が払拭できない。一方、データそれ自体をインターネットには置かずに、安全なイントラネットに置く方式の、サーバーとデータをファイヤーウォールを介してハッシュで連携させるハッシュ型クラウドサーバーを使った特許文献３の様なハッシュ型不正アクセス防止策もあるが、この方式はデータをイントラに格納する必要がある為、予め手元にあるデータかイントラ内で発生したデータでしか使えない。 However, these conventional unauthorized access prevention measures are compared with the wisdom of those who try to gain unauthorized access as technology advances, and as long as the data is on the Internet, what measures are being taken to prevent unauthorized access to data? I don't know if it will be broken, and I can't get rid of the fear of unauthorized access. On the other hand, a hash type fraud as disclosed in Patent Document 3 using a hash type cloud server in which data is placed on a secure intranet without using it on the Internet, and the server and the data are linked with each other through a hash. Although there is an access prevention measure, since this method needs to store data in the intra, it can be used only with data in hand or data generated in the intra.

    解決しようとする問題は、ハッシュ型クラウドサーバーではデータが予めイントラネットに格納されている必要があるが、外部コミュニケーションツールは入力データの内容が予測できない為、予めイントラネットに格納しておくことが出来ず、外部コミュニケーションツールではハッシュ型クラウドサーバーが使えないと言う課題がある。 The problem to be solved is that the hash type cloud server needs to store the data in the intranet in advance, but the external communication tool cannot predict the contents of the input data, so it cannot be stored in the intranet in advance. The external communication tool has a problem that the hash cloud server cannot be used.
　本発明は、インターネット上で予測出来ないデータが入力されるクラウドサーバーにハッシュ型クラウドサーバーが使える様にする為に、その入力されたデータのＩＤを生成し、そのＩＤのコピーとそのデータ自体を関連付けて、安全なイントラネットのデータ格納装置に移動することを主な特徴とする。 The present invention generates an ID of the input data so that the cloud server to which data that cannot be predicted on the Internet is input can be used, and copies the ID and the data itself. The main feature is to move to a secure intranet data storage device in association.
　本発明は、ハッシュ型不正アクセス防止策が外部コミュニケーションツールで使える利点がある。 The present invention has an advantage that a hash type unauthorized access prevention measure can be used with an external communication tool.

　インターネット上で新たに入力されるデータは、そのデータのＩＤを作成し、そのＩＤのコピーとそのデータを関連付けた状態でイントラネットのイントラデータ格納装置に格納し、インターネット上のそのデータ自体は削除する。その後インターネット上ではそのＩＤで処理し、必要に応じてそのＩＤをイントラネットにダウンロードしイントラデータ格納装置に格納したデータに置き替えることにより、外部コミュニケーションツールでハッシュ型クラウドサーバーが使用できる様になる。 For newly input data on the Internet, an ID of the data is created, a copy of the ID is associated with the data, stored in an intranet storage device of the intranet, and the data itself on the Internet is deleted. . Thereafter, processing on the Internet is performed with the ID, and if necessary, the ID is downloaded to the intranet and replaced with the data stored in the intra data storage device, so that the hash type cloud server can be used with an external communication tool.

Connected to the Internet 4 are a data input device 10, a data processing device 1 that generates a unique ID of data, and a data storage device 2 that stores data and ID. The intranet 5 connected via the firewall 6 polls if there is new data in the data storage device 2 and stores the downloaded data and ID if the data download device 8 downloads the new data. The intra data storage device 9 is connected.
　図４は本発明の動作説明図である。データ入力装置１０の表１１にデータ(BBBB)が入力されると、前記データ(BBBB)は動作１４の様にデータ格納装置２の表１２のデータ列にコピーされる。次に前記データ(BBBB)に関連付けられたＩＤ(id12)が動作１５の様に生成され表１２のＩＤ列に格納される。同時に前記ＩＤ(id12)はデータ入力装置１０の表１１にもコピーされ前記データ(BBBB)を上書きするので、前記データ(BBBB)は削除され、代わりに前記ＩＤ(id12)が格納されている状態になる。一方、データダウンロード装置８は常にデータ格納装置２の表１２に新たなデータが格納されたかをポーリングしており、前記データ(BBBB)が格納されると、動作１７の様に前記データ(BBBB)をダウンロードし、イントラデータ格納装置９の表１３に移動し表１２の前記データ(BBBB)は削除され、前記ＩＤ(id12)も動作１６の様にイントラデータ格納装置９の表１３に前記データ(BBBB)と関連付けられて格納される。表１２の前記ＩＤ(id12)は削除しないで、そのまま残す。 FIG. 4 is a diagram for explaining the operation of the present invention. When data (BBBB) is input to the table 11 of the data input device 10, the data (BBBB) is copied to the data string of the table 12 of the data storage device 2 as in the operation 14. Next, an ID (id12) associated with the data (BBBB) is generated as in operation 15 and stored in the ID column of Table 12. At the same time, the ID (id12) is copied to the table 11 of the data input device 10 and overwrites the data (BBBB). Therefore, the data (BBBB) is deleted and the ID (id12) is stored instead. become. On the other hand, the data download device 8 always polls whether new data is stored in the table 12 of the data storage device 2. When the data (BBBB) is stored, the data (BBBB) is stored as in operation 17. Is moved to the table 13 of the intra data storage device 9, the data (BBBB) in the table 12 is deleted, and the ID (id12) is also stored in the table 13 of the intra data storage device 9 as in operation 16. BBBB) and stored. The ID (id12) in Table 12 is not deleted and remains as it is.
　図５は本発明を実装したハッシュ型クラウドサーバーの配置図例である。図３の本発明の配置図に対し、イントラネット５にデータ連携装置７とクライアント端末３を追加接続する。 FIG. 5 is an example of an arrangement diagram of a hash type cloud server in which the present invention is implemented. The data link device 7 and the client terminal 3 are additionally connected to the intranet 5 with respect to the layout diagram of the present invention shown in FIG.
　　図６は本発明を実装したハッシュ型クラウドサーバーの動作説明図である。図４で説明した様にデータ入力装置１０に入力されたデータ（BBBB）がイントラデータ格納装置９の表１３に格納されているので、その前記データ（BBBB）がハッシュ型クラウドサーバーのクライアント端末３に表示される動作を説明する。クライアント端末３がハッシュ型クラウドサーバーにアクセスすると、データ連携装置７がデータ格納装置２の表１２から動作２１の様にＩＤ(id12)を表１９にコピーし、その前記ＩＤ(id12)をイントラデータ格納装置９に動作２２の様に送ると、その前記ＩＤ(id12)に関係付けられた前記データ(BBBB)が動作２３の様にデータ連携装置７の表１９にコピーされ、前記ＩＤ(id12)を上書きする。次にデータ連携装置７は表１９の内容をクライアント端末３の表２０にコピーし、前記データ(BBBB)が表示される。 FIG. 6 is an operation explanatory diagram of a hash type cloud server in which the present invention is implemented. Since the data (BBBB) input to the data input device 10 is stored in the table 13 of the intra data storage device 9 as described in FIG. 4, the data (BBBB) is stored in the client terminal 3 of the hash type cloud server. The operation displayed on the screen will be described. When the client terminal 3 accesses the hash type cloud server, the data linkage device 7 copies the ID (id12) from the table 12 of the data storage device 2 to the table 19 as shown in the operation 21, and the ID (id12) is used as the intra data. When sent to the storage device 9 as in operation 22, the data (BBBB) related to the ID (id12) is copied to the table 19 of the data linkage device 7 as in operation 23, and the ID (id12) Is overwritten. Next, the data linkage apparatus 7 copies the contents of Table 19 to the Table 20 of the client terminal 3, and the data (BBBB) is displayed.
　本発明は、外部コミュニケーションツールに限らず、新たに追加されるデータを扱うタイプの幅広い用途のクラウドサーバーで、ハッシュ型不正アクセス防止策が使える可能性がある。 The present invention is not limited to an external communication tool, and there is a possibility that a hash-type unauthorized access prevention measure can be used in a wide range of cloud servers that handle newly added data.
