Description

情報機器装置、情報機器装置用プログラム及び情報機器装置への不正アクセス防止方法Information equipment equipment, information equipment equipment programs, and methods for preventing unauthorized access to information equipment equipment
　本発明は、情報機器装置、情報機器装置用プログラム、及び情報機器装置への不正アクセス防止方法に関する。 The present invention relates to an information device, a program for the information device, and a method for preventing unauthorized access to the information device.
　近年、インターネット等の通信環境が整備され、それを基礎とした電子メールの送受信、広告配信、電子商取引、電子申請等が盛んに行われるようになっている。このような通信環境の発達に伴い、例えば、スマートフォンやタブレット端末をはじめとする携帯端末装置、或いはパーソナルコンピュータ（以下、これらを総称して「情報機器装置」という。）には、その情報機器装置の使用者の個人情報、第三者とのメールのやり取り、さらには取引先の情報など重要な秘匿性の高い情報が保存されることが多くなっている。 In recent years, communication environments such as the Internet have been improved, and e-mail transmission / reception, advertisement distribution, electronic commerce, electronic application, etc. based on the communication environment have been actively carried out. With the development of such a communication environment, for example, a portable terminal devices such as smartphones and the tablet terminal, or a personal computer (hereinafter collectively. As "information device system"), the information equipment Important and highly confidential information such as personal information of device users, exchange of emails with third parties, and information of business partners is often stored.
　そして、第三者がこれらの情報機器装置に保存された情報に容易にアクセスできないようにするセキュリティー確保の重要性が高まり、その情報機器装置を所有（使用）する者を認証（個人認証）する認証技術が普及しつつある。一般的に、情報機器装置へのアクセスに際しての個人認証の手段としては、例えばＩＤやパスワード等を用いたりするものが―般的であるが、その他にも指紋情報や顔情報などといった生体情報を用いて個人を特定する認証方法が知られている（例えば特許文献１や特許文献２)。そして、これらの認証方法に基づいて、その情報機器装置にログイン（使用）できるにユーザーが限定される。 Then, it is becoming more important to ensure security so that a third party cannot easily access the information stored in these information devices, and the person who owns (uses) the information devices is authenticated (individual authentication). Authentication technology is becoming widespread. Generally, as a means of personal authentication when accessing an information device, for example, an ID or a password is generally used-but other biometric information such as fingerprint information and face information is also used. An authentication method for identifying an individual by using it is known (for example, Patent Document 1 and Patent Document 2). Then, based on these authentication methods, the user is limited to be able to log in (use) the information device.
また、特許文献３には、第三者が他人の情報機器装置に不正にアクセスしようとする行為を検知した場合に警報音等により報知する警報装置が開示されている。具体的には、警報装置は外部からの力に反応するセンサを備えており、他人に見られたくない情報機器装置や手帳に警報装置を設置しておき、他人が情報機器装置等を拾い上げたり、傾けたりしたときにセンサが反応して、警報音が自動的に発生されるというものである。 Further, Patent Document 3 discloses an alarm device that notifies by an alarm sound or the like when a third party detects an act of illegally accessing another person's information device device. Specifically, the alarm device is equipped with a sensor that responds to external forces, and the alarm device is installed in an information device device or notebook that you do not want others to see, and others pick up the information device device, etc. , The sensor reacts when tilted, and an alarm sound is automatically generated.

　しかしながら、情報機器装置にＩＤやパスワードを設定したとしても、近年の情報犯罪の高度化により、それらＩＤやパスワードを不正に取得される機会が増えている。また、特許文献１や特許文献２に開示の技術のように、指紋情報とかいった生体情報を情報機器装置に登録した場合であっても、本人の睡眠中に第三者により指紋認証されることで容易に情報機器装置へのアクセスを許可してしまうおそれがある。 However, even if an ID or password is set in an information device, the chances of illegally obtaining the ID or password are increasing due to the sophistication of information crimes in recent years. Also, as the technique disclosed in Patent Documents 1 and 2, even when the registered fingerprint information Toka said biometric information in the information equipment device is fingerprint authentication by a third party during his or her sleep As a result, access to information equipment may be easily permitted.
　また、特許文献３に開示の警報装置においては、不正アクセスがあったことを周囲に知らせることができるが、外出時には警報装置を常時持参する必要があるとともに、本人の誤操作により警報音が発信される場合がある等、必ずしも実用的なものとはなっていなかった。 Further, in the alarm device disclosed in Patent Document 3, it is possible to notify the surroundings that there has been an unauthorized access, but it is necessary to always bring the alarm device when going out, and an alarm sound is transmitted due to an erroneous operation by the person himself / herself. It was not always practical, such as in some cases.
　さらに、特許文献1乃至特許文献３に係る技術においては、情報機器装置へ不正アクセスを試みようとする第三者を特定する技術については何ら開示がされていない。 Further, in the technique in the Patent Document 1 to Patent Document 3, not been no disclosure about a technology for identifying a third party to attempt to gain unauthorized access to the information equipment device.
　本発明は、以上の点に鑑みて創案されたものであって、携帯端末装置等の情報機器装置へ不正にアクセスをして情報収集を行おうとする第三者を監視し、特定することができる情報機器装置、情報機器装置用プログラム、及び情報機器装置への不正アクセス防止方法を提供することを目的とするものである。 The present invention was devised in view of the above points, and can monitor and identify a third party who attempts to illegally access an information device such as a mobile terminal device to collect information. It is an object of the present invention to provide an information device device, a program for the information device device, and a method for preventing unauthorized access to the information device device.
　前記の目的を達成するために、本発明に係る情報機器装置は、電源がオン状態により所定の情報が表示される表示部と、第１のユーザーに関する第１の生体情報が記憶された第１の生体情報記憶部と、第２のユーザーからの操作信号を受信する受信部と、前記表示部の表示方向にレンズが向けられ、前記受信部により前記操作信号を受信した際に第２のユーザーを撮像するカメラ部と、前記カメラ部により撮像された第２のユーザーに関する第２の生体情報を記憶する第２の生体情報記憶部と、前記第１の生体情報と前記第２の生体情報を照合する生体認証部と、を備える。 In order to achieve the above object, the information device according to the present invention has a display unit in which predetermined information is displayed when the power is on, and a first biometric information about a first user is stored. When the lens is pointed in the display direction of the biometric information storage unit, the receiving unit that receives the operation signal from the second user, and the display unit, and the receiving unit receives the operation signal, the second user A camera unit that captures images, a second biological information storage unit that stores a second biological information regarding a second user imaged by the camera unit, the first biological information, and the second biological information. It is provided with a biometric authentication unit for collation.
　ここで、電源がオン状態により所定の情報が表示される表示部を備えることにより、表示部を通じてインターネット等の通信回線を通じて取得した電子メール、ウェブサイト等の様々な情報を閲覧することができる。 Here, by providing a display unit that displays predetermined information when the power is on, various information such as e-mails and websites acquired through a communication line such as the Internet can be browsed through the display unit.
　また、第１のユーザーに関する第１の生体情報が記憶された第１の生体情報記憶部を備えることにより、情報機器装置の真のユーザーである第１のユーザーに関する生体情報（顔、指紋、綱膜、掌形等）を記憶させることができる。これにより、生体情報が照合した場合にのみ情報機器装置へのアクセスを許可することができるため、第三者からの不正アクセスの機会を低減することができる。 Further, by providing the first biometric information storage unit in which the first biometric information regarding the first user is stored, the biometric information (face, fingerprint, rope) regarding the first user who is the true user of the information device device is provided. Membrane, palm shape, etc.) can be memorized. As a result, access to the information device can be permitted only when the biometric information is collated, so that the chance of unauthorized access from a third party can be reduced.
　また、表示部の表示方向にレンズが向けられたカメラ部を備えることにより、情報機器装置を操作するユーザーの顔部分を焦点として撮像することができる。 Further, by providing a camera unit in which the lens is pointed in the display direction of the display unit, it is possible to take an image by focusing on the face portion of the user who operates the information device.
　また、カメラ部は、受信部により操作信号を受信すると、第２のユーザーの撮像を開始することにより、第２のユーザーによる操作に基づく操作信号をトリガーとして、カメラ部を起動して、情報機器装置を操作する第２のユーザーの顔を含めて撮像できる確率が高まる。即ち、不正アクセスを試みる第２のユーザーを特定できる可能性が高まる。 Further, when the camera unit receives the operation signal by the receiving unit, the camera unit starts imaging of the second user, triggers the operation signal based on the operation by the second user, and activates the camera unit to activate the information device. The probability that an image can be taken including the face of a second user who operates the device is increased. That is, the possibility of identifying a second user who attempts unauthorized access increases.
　また、前記カメラ部により撮像された第２のユーザーに関する第２の生体情報を取得して記憶する第２の生体情報記憶部を備えることにより、情報機器装置にアクセスを試みた第２のユーザーに関する生体情報（顔、指紋、網膜、掌形等）を記憶部に記憶させることができる。 Further, the second user who has attempted to access the information device device is provided with the second biometric information storage unit that acquires and stores the second biometric information regarding the second user imaged by the camera unit. Biological information (face, fingerprint, retina, palm shape, etc.) can be stored in the storage unit.
　また、第１の生体情報と第２の生体情報とを照合する生体認証部を備えることにより、情報機器装置へのアクセスを試みた第２のユーザーが真のユーザー（第１のユーザー）であるか否かを生体情報の照合に基づいて判定することができる。 Further, by providing a biometric authentication unit that collates the first biometric information with the second biometric information, the second user who tries to access the information device is a true user (first user). Whether or not it can be determined based on the collation of biometric information.
　また、受信部で受信する操作信号は、電源がオフ状態、又は省電力状態にある情報機器装置の電源起動直後の第２ユーザーによる操作に基づく操作信号である場合には、操作信号の受信状態に基づいて、第２のユ－ザーによる情報機器装置へのアクセスの有無を判別することができる。 If the operation signal received by the receiving unit is an operation signal based on an operation by a second user immediately after the power of the information device in the power-off state or the power saving state is turned on, the operation signal reception state.

Will be done. At this time, when a second user inputs some character string as a series of operations, the collation by the biometric authentication unit can be reliably started based on the operation signal. The purpose of the temporary password here is to receive an operation signal as a trigger for collation by the biometric authentication unit, and it is not necessary to determine whether or not the temporary password is collated.
　また、第１の生体情報は、第１のユーザーの顔を含む第１の画像データであり、第２の生体情報は、第２のユーザーの顔を含む第２の画像データである場合には、生体情報として人物判定が可能な顔の特徴に基づいて、第１のユーザーと第２のユーザーが同一人物であるか否かを判定することができる。 Further, when the first biometric information is the first image data including the face of the first user, and the second biometric information is the second image data including the face of the second user.

Will be done. At this time, when a second user inputs some character string as a series of operations, the collation by the biometric authentication unit can be reliably started based on the operation signal.

本発明の実施形態に係る情報機器装置の全体外観図である。It is an overall external view of the information equipment apparatus which concerns on embodiment of this invention. 本発明の実施形態に係る情報機器装置のブロック図を示す図である。It is a figure which shows the block diagram of the information equipment apparatus which concerns on embodiment of this invention. 本発明の実施形態に係る制御部における演算（処理）フロー図である。It is a calculation (processing) flow diagram in the control part which concerns on embodiment of this invention.
　以下、本発明の実施の形態について、図面を参酌しながら説明し、本発明の理解に供する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings to help understand the present invention.
　本発明の実施形態に係る情報機器装置１は、同一のユーザーが持ち歩くことを想定した携帯端末装置であり、例えばスマートフォン、タブレット端末、ノート型ＰＣ、ウェアラブル端末等である。なお、以下では説明の便宜上、スマートフォンを想定して説明するが、ネットワークを通じて外部機器と双方向に通信が可能な情報機器装置の全てが対象となる。 The information device device 1 according to the embodiment of the present invention is a mobile terminal device that is assumed to be carried by the same user, and is, for example, a smartphone, a tablet terminal, a notebook PC, a wearable terminal, or the like. In the following, for convenience of explanation, a smartphone will be described, but all information equipment devices capable of bidirectional communication with an external device via a network are targeted.
　情報機器装置１は、図１に示すような外観からなり、情報機器装置１に対する操作を行うための操作ボタン、或いはインターネット通信回線を通じて取得した情報や情報機器装置１内に記憶された情報を表示するためのディスプレイ画面からなる表示部２、表示部２の表示方向（インカメラ）、及び表示方向とは反対方向（アウトカメラ）の双方向に向けられたレンズを有するカメラ部３を備えている。 The information device device 1 has an appearance as shown in FIG. 1, and displays operation buttons for operating the information device device 1, information acquired through an Internet communication line, and information stored in the information device device 1. A camera unit 3 having a display unit 2 composed of a display screen, a display direction of the display unit 2 (in-camera), and a lens oriented in both directions opposite to the display direction (out-camera) is provided. ..
　ここで、必ずしも、操作ボタンは表示部２に表示される、所謂タッチパネル式である必要はない。例えば表示部２と操作ボタンが分離して配置される形態のものや、情報機器装置１と有線または無線で接続されるキーパッドを使用する形態のものであってもよい。 Here, the operation buttons do not necessarily have to be the so-called touch panel type displayed on the display unit 2. For example, the display unit 2 and the operation buttons may be arranged separately, or a keypad connected to the information device 1 by wire or wirelessly may be used.
　また、必ずしも、カメラ部３はインカメラ、及びアウトカメラの両方を備えている必要はない。本発明の実施形態においては、少なくとも情報機器装置１を操作中のユーザーを撮像可能なインカメラを備えていればよい。なお、以下説明におけるカメラ部３とはインカメラを意味する。 Also, the camera unit 3 does not necessarily have to have both an in-camera and an out-camera. In the embodiment of the present invention, at least an in-camera capable of capturing an image of a user who is operating the information device 1 may be provided. The camera unit 3 in the following description means an in-camera.
　情報機器装置１の内部構成は、図２に示すブロック図のように、データの送受信やデータの記憶、及び演算処理を行うための制御部４、第１の生体情報記憶部５、第２の生体情報記憶部６、受信部７、仮パスワード（ダミーパスワード）生成部８、生体認証部９、及び送信部１０から構成されている。 As shown in the block diagram shown in FIG. 2, the internal configuration of the information device device 1 includes a control unit 4 for transmitting / receiving data, storing data, and performing arithmetic processing, a first biometric information storage unit 5, and a second. It is composed of a biometric information storage unit 6, a receiving unit 7, a temporary password (dummy password) generating unit 8, a biometric authentication unit 9, and a transmitting unit 10.
　制御部４は、情報機器装置１に係る演算処理、及び制御処理を行う装置である。制御部４は、例えばＣＰＵ、ＲＡＭ、ＲＯＭ等の内部メモリを備える。係る制御部４による処理動作の詳細は後記する。 The control unit 4 is a device that performs arithmetic processing and control processing related to the information device device 1. The control unit 4 includes internal memories such as a CPU, RAM, and ROM. Details of the processing operation by the control unit 4 will be described later.
　第１の生体情報記憶部５は、情報機器装置１の真のユーザー（第１のユーザー）の生体情報を記憶しておくための記憶媒体である。生体情報としては、例えば顔画像、指紋、網膜、掌形等、あらゆる生体情報を記憶させることができる。これら第１の生体情報記憶部５に記憶された生体情報は、例えば、情報機器装置１の電源起動時にログインを試みるユーザー（第２のユーザー）の生体情報との照合に使用される。 The first biometric information storage unit 5 is a storage medium for storing the biometric information of the true user (first user) of the information device device 1. As the biological information, all kinds of biological information such as a face image, a fingerprint, a retina, and a palm shape can be stored. The biometric information stored in the first biometric information storage unit 5 is used, for example, for collation with the biometric information of a user (second user) who attempts to log in when the power of the information device device 1 is turned on.
　なお、本発明の実施形態においては、第１の生体情報記憶部５に記憶された生体情報としては、第１のユーザーの顔を含む画像データである（第１の画像データ）。この第１の画像データは、情報機器装置１に備えるカメラ部３で撮像された画像データであってもよく、或いは他の撮像装置で撮像された画像データであってもよい。 In the embodiment of the present invention, the biometric information stored in the first biometric information storage unit 5 is image data including the face of the first user (first image data). The first image data may be image data captured by the camera unit 3 provided in the information device device 1, or may be image data captured by another imaging device.
　ここで、必ずしも、情報機器装置１へのログイン方法としては、登録した生体情報による生体認証方法である必要はない。例えば、ＩＤやパスワードといった文字列を入力する方式のものや、生体情報と文字列を入力する方式のものを併用するものであってもよい。即ち、真のユーザーである第１のユーザーのみが知るＩＤやパスワードを入力することで情報機器装置１へのログインを許可することもできる。 Here, the login method to the information device device 1 does not necessarily have to be the biometric authentication method using the registered biometric information. For example, a method of inputting a character string such as an ID or a password, or a method of inputting biometric information and a character string may be used in combination. That is, it is possible to allow login to the information device device 1 by inputting an ID and a password known only to the first user who is a true user.
　第２の生体情報記憶部６は、情報機器装置の電源起動時にログインを試みる第２のユーザーの生体情報を記憶するための記憶媒体である。即ち、後記する通り、第２のユーザーによる情報機器装置１へのアクセスがあった場合に、ログインを試みる第２のユーザーの生体情報（第２の生体情報）を取得し、第１の生体情報記憶部５に記憶されている第１のユーザーの生体情報（第1の生体情報）と照合される。この時、第１の生体情報と第２の生体情報が照合する場合には、第１のユーザーと第２のユーザーは同一人物であるとして情報機器装置１へのログインを許可し、そうでない場合は不正アクセスとしてログインを制限する。 The second biometric information storage unit 6 is a storage medium for storing the biometric information of the second user who tries to log in when the power of the information device device is turned on. That is, as described later, when the information device device 1 is accessed by the second user, the biometric information (second biometric information) of the second user who tries to log in is acquired, and the first biometric information is obtained. It is collated with the biometric information (first biometric information) of the first user stored in the storage unit 5. At this time, when the first biometric information and the second biometric information are collated, it is assumed that the first user and the second user are the same person, and login to the information device device 1 is permitted, otherwise. Restricts login as unauthorized access.
　なお、本発明の実施形態においては、第２の生体情報記憶部６に記憶される生体情報としては、カメラ部３で撮像された第２のユーザーの顔を含む画像データである（第２の画像データ）が、これに限定されるものではない。例えば、第１の生体情報が指紋情報である場合には、第２の生体情報は第２のユーザーの指紋情報が記憶されることになる。即ち、第１の生体情報と第２の生体情報は同種の情報である必要がある。 In the embodiment of the present invention, the biometric information stored in the second biometric information storage unit 6 is image data including the face of the second user captured by the camera unit 3 (second). Image data) is not limited to this. For example, when the first biometric information is fingerprint information, the second biometric information stores the fingerprint information of the second user. That is, the first biometric information and the second biometric information need to be the same kind of information.
　受信部７は、ユーザーによる情報機器装置１の操作ボタンを操作した場合の操作信号を受信する装置である。なお、受信部７は操作ボタンの操作信号だけでなく、情報機器装置１の電源のオンオフ信号も受信することが可能である。 The receiving unit 7 is a device that receives an operation signal when the user operates the operation button of the information device device 1. The receiving unit 7 can receive not only the operation signal of the operation button but also the on / off signal of the power supply of the information device device 1.
　受信部７と前記した制御部４は有線、又は無線により接続されており、受信部７が操作信号を受信すると、その信号が制御部４にも送信され、操作信号を受けた制御部４はカメラ部３を起動させ、撮像制御を開始する構成となっている。 The receiving unit 7 and the control unit 4 described above are connected by wire or wirelessly, and when the receiving unit 7 receives an operation signal, the signal is also transmitted to the control unit 4, and the control unit 4 that receives the operation signal The camera unit 3 is activated to start imaging control.
　ここで、必ずしも、操作信号は受信部７を介して制御部４に送信される必要はない。例えば、操作信号が受信部７を介することなく、制御部４に直接送信される構成としてもよい。この場合制御部４が受信部７としての機能を有することになる。 Here, the operation signal does not necessarily have to be transmitted to the control unit 4 via the reception unit 7. For example, the operation signal may be directly transmitted to the control unit 4 without going through the reception unit 7. In this case, the control unit 4 has a function as a reception unit 7.
　仮パスワード生成部８は、ランダムの文字列からなる仮パスワードを生成する装置である。仮パスワードは、情報機器装置１の電源投入の信号を受信部７で受信すると生成され、前記したログイン用のパスワードとは異なり、第２のユーザーに対して操作ボタンによる操作を誘導するためのダミーパスワードとして使用されるものである。 The temporary password generation unit 8 is a device that generates a temporary password composed of a random character string. The temporary password is generated when the power-on signal of the information device device 1 is received by the receiving unit 7, and is different from the login password described above, and is a dummy for inducing the second user to operate with the operation buttons. It is used as a password.
　なお、仮パスワード生成部８で生成される仮パスワードは、情報機器装置１の電源がオンされる都度、ランダムの文字列が生成されるとともに、表示部２に入力画面が表示される。このとき、図１に示すように、例えば仮パスワードが４文字の文字列からなる場合に、その一部である３文字までをヒントとして表示し、残りの非表示の１文字が推測しやすい表示形態として表示される。なお、この入力画面において第１のユーザーのみが知る真のパスワードを入力すると、前記した通り情報機器装置１へのログインが許可される。 For the temporary password generated by the temporary password generation unit 8, a random character string is generated each time the power of the information device device 1 is turned on, and an input screen is displayed on the display unit 2. At this time, as shown in FIG. 1, for example, when the temporary password consists of a character string of 4 characters, up to 3 characters which are a part of the temporary password are displayed as hints, and the remaining hidden 1 character is easy to guess. Displayed as a form. If a true password known only to the first user is entered on this input screen, login to the information device 1 is permitted as described above.
　ここで、必ずしも、仮パスワードは情報機器装置１の電源がオンされる都度、ランダムの文字列が生成される必要はない。例えば、固定の仮パスワードを仮パスワード生成部８に記憶させておき、係る固定の仮パスワードを電源がオンされる都度、ヒントとして表示部２に表示させるようにしてもよい。 Here, the temporary password does not necessarily have to generate a random character string each time the power of the information device device 1 is turned on. For example, the fixed temporary password may be stored in the temporary password generation unit 8, and the fixed temporary password may be displayed on the display unit 2 as a hint each time the power is turned on.
　また、表示部２への表示形態として、仮パスワードを構成する文字列の一部を表示する表示形態である必要はない。但し、仮パスワードの一部をヒントとして表示することで、第２のユーザーにとってはパスワードを構成する文字列を推測し易くなり、入力操作の動機付けとすることができる。即ち、第２のユーザーによる操作信号を受信部７で受信することにより第１のユーザーと第２ユーザーの照合を実施する場合には、仮パスワード（ダミーパスワード）が入力の動機付けを与えることができるため、第１のユーザーと第２のユーザーを照合する機会を増やすことができる。 Further, as the display form on the display unit 2, it is not necessary to display a part of the character string constituting the temporary password. However, by displaying a part of the temporary password as a hint, it becomes easier for the second user to guess the character string constituting the password, which can be used as a motivation for the input operation. That is, when the first user and the second user are collated by receiving the operation signal by the second user on the receiving unit 7, the temporary password (dummy password) may motivate the input. Therefore, it is possible to increase the chances of matching the first user with the second user.
　生体認証部９は、第1の生体情報記憶部５に記憶されている第１の画像データと、第２の生体情報記憶部６に記憶されている第２の画像データを照合するための装置である。なお、生体認証データとして、顔画像以外のデータ、例えば指紋を用いる場合には、第１のユーザーの指紋データと第２の指紋データの照合が行われる。 The biometric authentication unit 9 is a device for collating the first image data stored in the first biometric information storage unit 5 with the second image data stored in the second biometric information storage unit 6. Is. When data other than the face image, for example, a fingerprint is used as the biometric authentication data, the fingerprint data of the first user and the second fingerprint data are collated.
　ここで、必ずしも、制御部４は受信部７からの操作信号に基づいて力メラ部３の撮像制御を開始する必要はない。例えば、第２のユーザーの操作に基づく操作信号が直接制御部４に送信されるようにしてもよい。 Here, the control unit 4 does not necessarily have to start the imaging control of the force melody unit 3 based on the operation signal from the reception unit 7. For example, an operation signal based on the operation of the second user may be directly transmitted to the control unit 4.
　送信部１０は、第１のユーザーが予め登録した電子メールアドレス、或いは第１のユーザーが指定したネットワーク上に存在するフォルダに第２の画像データを送信するための装置である。後記する通り、第２のユーザーによるログインが制限された場合に、送信部１０を介して、第１のユーザーが登録した電子メールアドレス、或いはネットワーク上のフォルダに第２の画像デーダが送信されることで、第１のユーザーが外出先においても、情報機器装置１への不正ログインの有無を確認することが可能となる。 The transmission unit 10 is a device for transmitting the second image data to an e-mail address registered in advance by the first user or a folder existing on the network designated by the first user. As will be described later, when login by the second user is restricted, the second image data is transmitted to the e-mail address registered by the first user or a folder on the network via the transmission unit 10. As a result, the first user can confirm whether or not there is an unauthorized login to the information device device 1 even when he / she is away from home.
　以上が、本発明の実施形態に係る情報機器装置１の構成である。次に、情報機器装置１の制御部４における処理フローについて図３に基づいて説明する。 The above is the configuration of the information device 1 according to the embodiment of the present invention. Next, the processing flow in the control unit 4 of the information equipment device 1 will be described with reference to FIG.
　＜第1の生体情報の登録状況の確認＞
まず、第１のユーザーの生体情報が、第１の生体情報として第１の生体情報記憶部５に登録されているか否かが確認される(Ｓ１）。第１の生体情報が登録されていない場合には、情報機器装置1へのログイン方法としてＩＤまたはパスワードのみによるものであるとして、処理を終了する。一方、第１の生体情報が登録されている場合には、制御部４による処理を続行する。 <Confirmation of registration status of the first biometric information>
First, it is confirmed whether or not the biometric information of the first user is registered in the first biometric information storage unit 5 as the first biometric information (S1). If the first biometric information is not registered, it is assumed that the login method to the information device device 1 is only by the ID or password, and the process is terminated. On the other hand, when the first biometric information is registered, the process by the control unit 4 is continued.
　＜情報機器装置の電源状態の確認＞
情報機器装置１の電源がオフ状態、又は省電力状態からオン状態に移行したか否かが判定される（Ｓ２）。電源がオン状態の場合には、既に真のユーザーである第１のユーザーによる正式なログイン操作が行われて情報機器装置１が起動しているものと判断して、処理を終了する。一方、電源がオフ状態からオン状態となったと判定された場合には、第２のユーザーによるログイン操作が行われるものとして、処理を続行する。 <Checking the power status of information equipment>
It is determined whether or not the power supply of the information device device 1 has changed from the off state or the power saving state to the on state (S2). When the power is on, it is determined that the information device device 1 has already been activated by a formal login operation by the first user who is a true user, and the process ends. On the other hand, when it is determined that the power is changed from the off state to the on state, the process is continued assuming that the login operation by the second user is performed.
　＜パスワード入力画面の表示＞
Ｓ２において、電源オフ状態からオン状態に移行したと判定されると、パスワードの入力画面が表示部２に表示される(Ｓ３)。このとき、前記した通り、仮パスワード生成部８で生成された仮パスワードの文字列の一部がヒントとして表示され、隠された文字がある程度推測できる表示形態で表示される。 <Display of password input screen>
When it is determined in S2 that the power has changed from the off state to the on state, the password input screen is displayed on the display unit 2 (S3). At this time, as described above, a part of the temporary password character string generated by the temporary password generation unit 8 is displayed as a hint, and the hidden characters are displayed in a display form in which the hidden characters can be guessed to some extent.
　＜操作信号の受信確認＞
パスワードの入力画面において、第２のユーザーによる入力操作の有無が判定される（Ｓ４）。第２のユーザーによるパスワードの入力操作が行われない場合、即ち受信部７にて操作信号の受信が確認されない場合には、ログイン操作が中断されたものとして処理を終了する。一方、受信部７で操作信号を受信した場合には、ログイン操作が行われたものと判断する。 <Confirmation of reception of operation signal>
On the password input screen, it is determined whether or not there is an input operation by the second user (S4). If the password input operation by the second user is not performed, that is, if the reception unit 7 does not confirm the reception of the operation signal, the process is terminated as if the login operation was interrupted. On the other hand, when the receiving unit 7 receives the operation signal, it is determined that the login operation has been performed.
　＜撮像制御＞
Ｓ４において、第２のユーザーからの操作信号が受信部７で受信されると、制御部４によりカメラ部３が起動される。カメラ部３は表示部２を操作する第２のユーザーの顔部分を焦点として撮像を開始する（Ｓ５）。撮像された第２のユーザーの顔画像（第２の生体情報）は、第２の生体情報記憶部６に記憶される。 <Image control>
In S4, when the operation signal from the second user is received by the receiving unit 7, the camera unit 3 is activated by the control unit 4. The camera unit 3 starts imaging with the face portion of the second user who operates the display unit 2 as the focal point (S5). The captured second user's face image (second biometric information) is stored in the second biometric information storage unit 6.
　ここで、必ずしも、第２のユーザーからの操作信号として、第２のユーザーによるパスワードの入力に基づく操作信号である必要はない。例えば情報機器装置１の電源をオンする操作に基づく操作信号に基づいて撮像制御を開始するようにしてもよい。 Here, the operation signal from the second user does not necessarily have to be an operation signal based on the input of the password by the second user. For example, the imaging control may be started based on the operation signal based on the operation of turning on the power of the information device 1.
　Ｓ５において、第２の生体情報が取得されると、第１の生体情報との照合が行われる（Ｓ６）。このとき、第１の生体情報と第２の生体情報が照合すると判定された場合には、第１のユーザーと第２のユーザーは同一人物であるため、情報機器装置１へのログインが許可される（Ｓ７）。 When the second biometric information is acquired in S5, it is collated with the first biometric information (S6). At this time, if it is determined that the first biometric information and the second biometric information are collated, since the first user and the second user are the same person, login to the information device device 1 is permitted. (S7).
　一方、第１の生体情報と第２の生体情報が照合しないと判定された場合には、第１のユーザーと第２のユーザーは異なる人物であるため、情報機器装置１に対する不正アクセスがあったものとして、情報機器装１へのログインが制限され、情報機器装置１の操作をロックして処理を終了する。 On the other hand, when it is determined that the first biometric information and the second biometric information do not collate, since the first user and the second user are different persons, there is an unauthorized access to the information device device 1. As a result, login to the information device 1 is restricted, the operation of the information device 1 is locked, and the process ends.
　情報機器装置１へのログインが制限された場合、第２の生体情報記憶部６には第２のユーザーの顔画像が記憶されている。従って、第１のユーザーは第２の生体情報記憶部６に記憶された顔画像を確認することで、情報機器装置１への不正アクセスを行おうとした第２のユーザーを特定することができる。 When login to the information device device 1 is restricted, the face image of the second user is stored in the second biometric information storage unit 6. Therefore, the first user can identify the second user who tried to gain unauthorized access to the information device device 1 by checking the face image stored in the second biometric information storage unit 6.
　このとき、第１のユーザーが予め登録された電子メールアドレス、或いはネットワーク上のフォルダに第２の生体情報（第２の画像データ）が送信されるように設定することもできる。このように、情報機器装置１へのログインが制限された場合に、それに連動して第２の画像データが、登録した電子メールアドレスやネットワーク上のフォルダに送信されることで、第１のユーザーが外出先においても、情報機器装置１への不正ログインがあったことを認識することができる。 At this time, it is also possible to set the first user to send the second biometric information (second image data) to the pre-registered e-mail address or the folder on the network. In this way, when login to the information device device 1 is restricted, the second image data is transmitted to the registered e-mail address or the folder on the network in conjunction with it, so that the first user However, it is possible to recognize that there was an unauthorized login to the information device 1 even when the user is away from home.
　ここで、生体情報として指紋情報を使用する場合には、例えば表示部２に指紋センサを備えておき、表示部２を操作する第２のユーザーの指紋情報を取得し、該指紋情報を第２の生体情報記憶部６に記憶するようにしてもよい。 Here, when using fingerprint information as biometric information, for example contact can comprise a fingerprint sensor on the display unit 2, it acquires the fingerprint information of the second user operating the display unit 2, first the fingerprint information It may be stored in the biological information storage unit 6 of 2.
　なお、生体情報として指紋情報を使用する場合でも、制御部４によりカメラ部３の撮像は行われる。これにより、第２のユーザーの顔画像を撮像することができるため、不正アクセスを行おうとした第２のユーザーを特定することができる。 Even when fingerprint information is used as biometric information, the control unit 4 takes an image of the camera unit 3. As a result, the face image of the second user can be captured, so that the second user who tried to perform unauthorized access can be identified.
