現在、機密データへのアクセスや、工作機械や、建設機械など特定の人間しか操作が許可されていない装置を操作する際、パスワードやＩＣカード、あるいは生体認証による本人確認が行われている。
一方、これらの本人確認は操作開始時、例えば、個人情報や未発表情報などの機密データにアクセスに先立って一度だけ行なわれるものが多い。そのため、本人認証を行った環境においてはその後の操作は本人でなくても操作できてしまうという問題があった。例えば、パーソナルコンピュータの起動時に本人確認が必要な場合は、起動時に本人認証を行い、成功すると、本人以外でもそのパーソナルコンピュータが管理・共有している機密データを閲覧・変更することができるようになるという問題があった。 Currently, access to confidential data, and operation of devices that are permitted to be operated only by a specific person such as a machine tool or construction machine, identity verification is performed using a password, an IC card, or biometric authentication.
On the other hand, such identity verification is often performed once at the start of the operation, for example, prior to accessing confidential data such as personal information and unpublished information. For this reason, there is a problem that in the environment where the personal authentication is performed, the subsequent operation can be performed even by a non-person. For example, if personal identification is required at startup of a personal computer, authentication of the user is performed at startup, and if successful, the confidential data managed and shared by the personal computer can be viewed and changed by others. There was a problem of becoming.

本発明の目的は、生体認証を使用し、機密情報へのアクセスや工作機械の操作の全期間に渡って本人認証を行なうことにより、操作途中で本人以外の者の操作を抑止すること、利用者が機密データを含むファイルの閲覧、編集作業を行なう際に本人確認を利用者が意識することなくリアルタイムに行なえるようにした生体認証搭装置を提供することにある。   The purpose of the present invention is to use biometric authentication to suppress the operation of a person other than the user during the operation by performing personal authentication over the entire period of access to confidential information and operation of the machine tool. It is an object of the present invention to provide a biometric tower device that enables a user to perform identity verification in real time without a user's awareness when browsing or editing a file containing confidential data.

上記目的を達成するために、本発明の生体認証装置は、操作対象を操作しようとする利用者の生体情報を撮影する撮影手段と、撮影された生体情報とデータベースに予め登録されている利用者本人の生体情報とを照合し、利用者本人であるかを判定する判定手段と、前記撮影手段および判定手段を制御し、生体情報を定期的または常時撮影し、その撮影した撮影情報に基づき利用者本人であるか否かを定期的または常時判定し、操作対象を操作しようとする利用者が利用者本人であることを継続的に認証し、その結果に応じて操作対象の継続操作を許可または抑止する制御手段とを有することを特徴とする。
そして、前記撮影手段は、操作対象を操作する操作子に取り付けられていること特徴とする。 In order to achieve the above object, a biometric authentication apparatus according to the present invention includes a photographing unit that photographs biometric information of a user who intends to operate an operation target, and a user registered in advance in the captured biometric information and database. A determination unit that compares the biometric information of the user and determines whether the user is the user, and controls the imaging unit and the determination unit, and periodically or constantly captures the biometric information and uses it based on the captured imaging information. Periodically or constantly determining whether the user is the user himself / herself, continuously authenticating that the user who wants to operate the operation target is the user himself / herself, and allowing continuous operation of the operation target according to the result Or a control means for inhibiting.
And the said imaging | photography means is attached to the operation element which operates an operation target.

本発明によれば、操作対象を操作しようとする利用者が本人であるか否かを継続的に認証するため、最初は利用者本人であることが認証されたとしても途中で操作する人が別人に変わった場合には、継続的な認証が否定されることになり、直ちに操作対象を操作することが不可能になる。
従って、本認証装置を自動車のハンドル操作者を認証するための装置として取り付けた場合、予め登録しておいた利用者以外の者が運転しようとしたときには、本人認証が否定され、継続的な運転できなくなり、盗難予防に役立てることが可能になる。
また、パーソナルコンピュータのマウスに適用した場合、予め登録しておいた利用者以外の者が機密情報などにアクセスしようとしても抑止され、機密情報の漏洩を防止することが可能になる。
また、工作機械の操作ハンドルの操作者を認証するための装置として取り付けた場合、予め登録しておいた操作者以外の者が操作しようとしたときには、本人認証が否定され、操作がすることが抑止され、事故の発生が未然に防止される。 According to the present invention, in order to continuously authenticate whether or not the user who intends to operate the operation target is the person himself / herself, even if the user is initially authenticated as the user himself / herself, In the case of changing to another person, continuous authentication is denied, and it becomes impossible to immediately operate the operation target.
Therefore, when this authentication device is installed as a device for authenticating the steering wheel operator of a car, when a person other than a pre-registered user tries to drive, the user authentication is denied and continuous driving is performed. It becomes impossible to use it for theft prevention.
In addition, when applied to a mouse of a personal computer, even if a user other than a registered user tries to access confidential information or the like, the confidential information is prevented from being leaked.
In addition, when it is installed as a device for authenticating the operator of the operation handle of the machine tool, when a person other than the operator registered in advance tries to operate it, the personal authentication is denied and the operator can operate. Deterred and accidents are prevented.
