Description

本発明は、生体情報を使用して、プリペイド式携帯端末を持つ利用者に対して、本人確認を確実で簡単に行うことのできる認証技術に関する。   The present invention relates to an authentication technique capable of reliably and easily performing identity verification for a user having a prepaid portable terminal using biometric information.

端末販売店舗のみならず、コンビニエンスストア等でも購入でき、契約時の手続きが容易なことから、プリペイド式携帯電話が普及しつつある。このようなプリペイド式携帯電話サービスを今後も維持していくためには、不正利用をできるだけ抑止することが可能な方法を導入することが必須となってきている。   Prepaid mobile phones are becoming popular because they can be purchased not only at terminal sales stores but also at convenience stores and the like, and the procedures at the time of contract are easy. In order to maintain such a prepaid mobile phone service in the future, it has become essential to introduce a method capable of suppressing unauthorized use as much as possible.

ところで、現在、提供されているプリペイド携帯電話サービスにおいて、本人確認を行うには、運転免許証、パスポート、外国人登録証明書など写真入の公的書類の提示が必要になっている。そのため、利用者は、本人確認のため、定期的に店舗等に出向き、写真入公的書類との照会をする必要がある。また、各利用者の登録状態を一人ずつ手入力にて管理する必要がある。   By the way, in the prepaid mobile phone service currently provided, in order to verify the identity, it is necessary to present public documents with photographs such as a driver's license, passport, and alien registration certificate. For this reason, the user needs to go to a store or the like on a regular basis to confirm the identity of the user and make an inquiry with the official photo document. Moreover, it is necessary to manage the registration status of each user manually by one person.

また、個々の携帯端末の操作制限を実現する方法として、生体情報を利用する方法が一部メーカより提供されている携帯端末で採用されている。この方法は、携帯端末内部に登録された生体情報と携帯端末に装備されている読取装置から入力された生体情報とを照合することにより、操作制限あるいは解除の設定を行うというものである。   In addition, as a method for realizing the operation restriction of individual mobile terminals, a method using biometric information is adopted in some mobile terminals provided by manufacturers. In this method, operation restriction or cancellation is set by collating biometric information registered in the mobile terminal with biometric information input from a reading device installed in the mobile terminal.

携帯端末利用サービスにおいて、生体情報を利用した適用例として、例えば特開２００４−１３７５３号公報（従来技術１）に記載の技術が知られている。この従来技術１は、管理制限区域への入隊室管理に応用している。あらかじめ生体情報を記録したＩＣカードを用意しておき、カードリーダが装備されている携帯端末に挿入し、携帯端末からドアの開錠要求を行う。送られた情報は、管理制限区域入口にあるドアコントローラに送信される。ドアコントローラには、生体情報の読取装置があり、ここから生体情報を入力し、先に送った生体情報との照合により、ドア開錠・施錠を制御するものである。   As an application example using biological information in a mobile terminal use service, for example, a technique described in Japanese Patent Application Laid-Open No. 2004-13753 (Prior Art 1) is known. This prior art 1 is applied to enrollment room management in a restricted management area. An IC card in which biometric information is recorded in advance is prepared, inserted into a mobile terminal equipped with a card reader, and a door unlock request is made from the mobile terminal. The sent information is sent to the door controller at the entrance of the restricted area. The door controller includes a biometric information reader. The biometric information is input from the door controller, and door unlocking / locking is controlled by collating with the biometric information sent earlier.

また、従来技術１に類似する技術としては、例えば特開２００１−１１７８７８号公報（従来技術２）がある。この従来技術２は、携帯電話から入力された生体情報を、サービスプロバイダへ送信し、さらに認証サーバへ送信される。そして、認証サーバには、あらかじめ登録してある利用者の生体情報が保存されており、このデータとサービスプロバイダから送られてきた生体情報と照合し、結果をサービスプロバイダに返信する、といった適用例である。   Moreover, as a technique similar to the prior art 1, there exists Unexamined-Japanese-Patent No. 2001-117878 (prior art 2), for example. This prior art 2 transmits biometric information input from a mobile phone to a service provider and further to an authentication server. The authentication server stores biometric information of a user registered in advance, and compares the data with the biometric information sent from the service provider and returns the result to the service provider. It is.

上記従来技術１及び２は、いずれも認証をその都度行う必要があり、現行のプリペイド携帯電話サービスの本人確認の方法としては、手続きが煩雑で使い勝手がよくない。   Both the prior arts 1 and 2 require authentication each time, and the current prepaid mobile phone service identification method is cumbersome and unusable.

また、一度の本人確認を行うことにより、有効期限内であれば何度でもサービス提供を受けることが可能となるシステムの公知例としては、特開２００１−２９８７７９号公報（従来技術３）が知られている。この従来技術３においては、指紋データおよび有効期限情報は、携帯端末側で管理することになっている。   Japanese Patent Laid-Open No. 2001-29879 (Prior Art 3) is known as a well-known example of a system that allows a user to receive a service as many times as possible within the expiration date by performing identity verification once. It has been. In this prior art 3, fingerprint data and expiration date information are managed on the mobile terminal side.

特開２００４−１３７５３号公報JP 2004-137553 A 特開２００１−１１７８７８号公報JP 2001-117878 A 特開２００１−２９８７７９号公報JP 2001-298777 A

上記従来技術１及び２では、サービスの利用が必要になるたびに、その都度認証が必要であるという課題がある。プリペイド携帯端末のサービスを考えると、一度認証されたら、ある一定期間は認証することなく、サービス提供されることが望ましい。さらに、なりすまし等の不正利用問題を回避しつつ、店舗等まで出向く手間を省くことが可能な認証方法が要求される。   The prior arts 1 and 2 have a problem that authentication is required every time use of a service is required. Considering a service of a prepaid mobile terminal, it is desirable to provide a service without authentication for a certain period once authenticated. Furthermore, there is a need for an authentication method that can avoid the trouble of illegal use such as impersonation and the like and save the trouble of going to a store or the like.

また、従来技術３においては、生体情報および有効期限管理を携帯端末側で行うため、第３世代携帯端末で一般的になってきているＵＳＩＭカード等の差し替えにより携帯端末を切り替えるたびに、各携帯端末に対して再設定を行う必要があるという課題を有していた。   Moreover, in the prior art 3, since biometric information and expiration date management are performed on the mobile terminal side, each time the mobile terminal is switched by replacing a USIM card or the like that has become common in third-generation mobile terminals, There was a problem that it was necessary to reconfigure the terminal.

本発明の目的は、上記課題を解決すべく、携帯端末の切り替えに対しても特別な手続き等を行うことなく、プリペイド携帯端末等の本人確認を、簡単で確実に行うことができるようにした携帯端末本人確認システムを提供することにある。   The object of the present invention is to solve the above-mentioned problems, and can easily and surely confirm the identity of a prepaid mobile terminal, etc. without performing a special procedure for switching a mobile terminal.

次に、本発明に係る携帯端末本人確認システムにおける新規登録処理の一実施例について図４を用いて説明する。図４は、新規登録処理の一実施例を示す流れ図である。新規登録時においては、まだ本発明に係る携帯端末１０１は使用できないので、この部分は、上記ディスプレイ部１０２、音声処理部１０３、通信部１０４、生体情報入力部１０５の機能を含む登録装置１０１に置き換わる。このとき、登録装置１０１がＵＳＩＭカード等（記憶部）１０８の差し替え可能に構成される場合にはＵＳＩＭカード固有の電話番号に関する情報が設定されることになる。ステップ６０１で、利用者は登録装置１０１に対して、新規登録要求送信を行う。新規登録要求を受信した認証サーバ２０１は、ステップ６０２でデータベース３０１を検索し、ステップ６０３で、これから登録しようとしている上記電話番号に対応した利用者のデータがすでにデータベース３０１に登録されていないかどうか確認する。すでに登録されていると判断された場合、認証サーバ２０１は登録装置１０１に対し、ステップ６０４で、新規登録の拒否通知を行う。ステップ６０３で、未登録データと判断された場合、認証サーバ２０１は登録装置１０１に対し、ステップ６０５で上記電話番号に対応した利用者の生体情報の入力要求を行う。生体情報の入力要求を受けた登録装置１０１は、ステップ６０６で登録装置１０１上に生体情報の入力を促すメッセージを出す。これに対し、利用者はステップ６０７で、登録装置１０１より上記電話番号に対応した生体情報信号を入力・送信する。登録装置１０１より送信された上記電話番号に関する情報に対応した生体情報信号を認証サーバ２０１が受信すると、認証サーバ２０１はステップ６０８でデータベース３０１に対し、ステップ６０９で上記電話番号に関する情報対応した生体情報の登録および上記携帯端末使用の有効期限設定を行うと同時に、ゲートウエイ装置４０１に対し、上記電話番号による携帯端末の使用許可設定を行う。使用許可設定が完了すると、ゲートウエイ装置４０１は、認証サーバ２０１に対して、ステップ６１０で使用許可応答を行う。使用許可応答を受信した認証サーバ２０１は、ステップ６１１で登録装置１０１に対して使用許可応答信号を送信し、該使用許可応答信号を受信した登録装置１０１は、ステップ６１２で使用が許可されたことをディスプレイ部１０２又は／及び音声処理部１０３を用いて利用者に通知する。なお、登録装置１０１と認証サーバ２０１との信号の送受信はゲートウエイ装置４０１を介して行われる。以上が新規登録時の流れとなり、認証サーバ２０１は定期的にデータベース３０１にアクセスを行い、有効期限が近づくまではゲートウエイ装置４０１に対して上記電話番号による携帯端末の使用を許可したままとなる。利用者も有効期限内であれば、利用の都度本人確認を行うことなく、上記電話番号による携帯端末を利用することができる。   Next, an example of a new registration process in the portable terminal identification system according to the present invention will be described with reference to FIG. FIG. 4 is a flowchart showing an embodiment of the new registration process. At the time of new registration, since the portable terminal 101 according to the present invention cannot be used yet, this portion is added to the registration device 101 including the functions of the display unit 102, the voice processing unit 103, the communication unit 104, and the biometric information input unit 105. Replace. At this time, when the registration apparatus 101 is configured to be able to replace the USIM card or the like (storage unit) 108, information related to the telephone number unique to the USIM card is set. In step 601, the user transmits a new registration request to the registration apparatus 101. Upon receiving the new registration request, the authentication server 201 searches the database 301 in step 602, and in step 603, whether or not the user data corresponding to the telephone number to be registered is already registered in the database 301. Check. If it is determined that it has already been registered, the authentication server 201 sends a new registration rejection notification to the registration apparatus 101 in step 604. If it is determined in step 603 that the data is unregistered data, the authentication server 201 requests the registration apparatus 101 to input biometric information of the user corresponding to the telephone number in step 605. Upon receiving the biometric information input request, the registration device 101 issues a message prompting the registration device 101 to input biometric information in step 606. On the other hand, in step 607, the user inputs / transmits a biometric information signal corresponding to the telephone number from the registration device 101. When the authentication server 201 receives the biometric information signal corresponding to the information related to the telephone number transmitted from the registration device 101, the authentication server 201 sends the biometric information corresponding to the information related to the telephone number in step 609 to the database 301 in step 608. Registration and the expiration date setting of the mobile terminal use are performed, and at the same time, the use permission setting of the mobile terminal by the telephone number is performed for the gateway device 401. When the use permission setting is completed, the gateway device 401 sends a use permission response to the authentication server 201 in step 610. The authentication server 201 that has received the use permission response transmits a use permission response signal to the registration apparatus 101 in step 611, and the registration apparatus 101 that has received the use permission response signal has been permitted to use in step 612.
