(Overview of the authentication device 1)
Hereinafter, an example of the authentication device 1 according to the first embodiment will be described with reference to the drawings. In FIGS. 1A, 1B, and 3, the flow of main information is indicated by arrows.

The authentication device 1 includes, for example, as illustrated in FIG. 1A, a frequency information generation unit 12 and a control unit 14 as an authentication unit. The control unit 14 performs authentication using biometric information or authentication using something other than biometric information. The authentication device 1 of the present embodiment, for example, performs reading and authentication of the biometric information 11, and thus further includes a biometric information sensor 10.
認証装置１の制御部１４は、他の認証装置によって認証された第１の登録者を認証順位の一番目とし、二番目以降をそれまで認証された登録者の頻度に基づいて定め、定めた認証順位に基づいて認証を行うように構成されている。 The control unit 14 of the authentication device 1 determines the first registrant authenticated by another authentication device as the first in the authentication order, and determines the second and subsequent registrants based on the frequency of the registrants authenticated so far. It is configured to perform authentication based on the authentication order.
この他の認証装置とは、一例として、図１Ｂに示す第１の認証装置２３である。この第１の認証装置２３は、一例として、主に車両の外において携帯機２２の認証を行うものである。車両の登録者は、例えば、携帯機２２を携帯して車両に近づくと、携帯機２２と第１の認証装置２３とが通信して認証を行う。第１の認証装置２３は、認証が成立する、つまり携帯機２２に登録された登録者、又は携帯機２２のＩＤが車両に登録された登録者である、又は登録されたＩＤであると認証すると、車両のドアの施錠を解除し、降車した後にはドアの施錠を行う。 The other authentication device is, for example, the first authentication device 23 shown in FIG. 1B. As an example, the first authentication device 23 mainly authenticates the portable device 22 outside the vehicle. For example, when the registrant of the vehicle carries the portable device 22 and approaches the vehicle, the portable device 22 and the first authentication device 23 communicate to perform authentication. The first authentication device 23 authenticates, that is, authenticates that the registrant registered in the portable device 22 or the ID of the portable device 22 is a registrant registered in the vehicle or a registered ID. Then, the door of the vehicle is unlocked, and after getting off, the door is locked.

In the present embodiment, it is assumed that a plurality of portable devices 22 can be registered in a vehicle. Then, it is assumed that the portable device 22 has its own ID and the registrant associated with each other.
携帯機２２は、一例として、第１の認証装置２３と無線通信を行い、ＩＤ情報Ｓ１を送信する。第１の認証装置２３は、受信したＩＤ情報Ｓ１と記憶する登録情報２３０とを比較して携帯機２２が車両に登録された携帯機であるか否かを判定する。このＩＤ情報Ｓ１は、例えば、携帯機２２の登録者ＩＤの情報である。また登録情報２３０は、例えば、登録された登録者ＩＤの情報を含んでいる。 The portable device 22, as an example, performs a first authentication apparatus 23 radio communication, transmits the ID information S 1. The first authentication apparatus 23 compares the registration information 230 and stores the received ID information S 1 and the portable device 22 determines whether the portable device registered in the vehicle. The ID information S 1 is, for example, information of a registrant ID of the portable device 22. The registration information 230 includes, for example, information on a registered registrant ID.
認証装置１は、例えば、図１Ｂに示すように、認証システム２の一部を構成している。具体的には、認証システム２は、認証を行う第１の認証装置２３と、第１の認証装置２３によって認証された第１の登録者を認証順位の一番目とし、二番目以降をそれまで認証された登録者の頻度に基づいて定め、定めた認証順位に基づいて認証を行う制御部１４を有する認証装置１と、を有する。 The authentication device 1 forms a part of an authentication system 2 as shown in FIG. 1B, for example. Specifically, the authentication system 2 sets the first authentication device 23 that performs authentication and the first registrant authenticated by the first authentication device 23 as the first in the authentication order, and sets the second and subsequent ones up to that time. And an authentication device 1 having a control unit 14 that determines based on the frequency of authenticated registrants and performs authentication based on the determined authentication order.
また認証システム２は、例えば、さらに生体情報以外を用いた認証を行う第２の認証装置２４を備えている。なお認証システム２は、複数の認証装置１及び複数の第２の認証装置２４を備えて構成されても良い。 The authentication system 2 further includes, for example, a second authentication device 24 that performs authentication using information other than biometric information. The authentication system 2 may include a plurality of authentication devices 1 and a plurality of second authentication devices 24.
認証システム２は、例えば、またさらに車両制御部２０と、車両ＬＡＮ（Local Area Network）２１と、を備えている。 The authentication system 2 further includes, for example, a vehicle control unit 20 and a vehicle LAN (Local Area Network) 21.
なお本実施の形態の認証システム２は、例えば、図１Ｂに示すように、車両制御部２０が登録者を識別する識別情報Ｓ４を生成して出力するように構成されているがこれに限定されない。変形例としての認証システム２は、認証を行う他の認証装置と、他の認証装置において認証が成立した登録者を識別する識別情報Ｓ４を出力する識別装置と、上述の制御部１４を備えた認証装置１と、を有する構成であっても良い。この識別装置は、例えば、第１の認証装置２３から出力される認証情報Ｓ２を取得して登録者を識別する識別情報Ｓ４を生成するように構成されている。 Incidentally authentication system 2 of this embodiment, for example, as shown in FIG. 1B, limited to this, but the vehicle controller 20 is configured to generate and output the identification information S 4 identifies the registrant Not done. Authentication system 2 as a modified example is provided with other authentication device for performing authentication, and identification device for outputting identification information identifying S 4 the registrant the authentication is successful in the other authentication devices, the control unit 14 of the above Authentication device 1. The identification device, for example, is configured to generate identification information identifying S 4 registrant acquires authentication information S 2 output from the first authentication device 23.
（生体情報センサ１０の構成）
認証装置１の生体情報センサ１０は、例えば、登録者の生体情報１１を読み取って制御部１４に出力するように構成されている。この生体情報センサ１０は、一例として、車両の駆動装置を始動、停止させるスタートスイッチ装置の操作ボタンに搭載されている。なお生体情報センサ１０は、一例として、スタートスイッチ装置以外に搭載されて顔画像、虹彩などの生体情報１１を用いた認証を行うように構成されても良い。 (Configuration of biological information sensor 10)
The biometric information sensor 10 of the authentication device 1 is configured to read, for example, biometric information 11 of a registrant and output it to the control unit 14. The biological information sensor 10 is mounted on, for example, an operation button of a start switch device that starts and stops a driving device of a vehicle. The biometric information sensor 10 may be configured to perform authentication using biometric information 11 such as a face image and an iris by being mounted on a device other than the start switch device, for example.
制御部１４は、例えば、生体情報センサ１０が読み取った操作ボタンを操作する操作指の指紋と、指紋の認証に用いるテンプレートと、を比較してユーザが登録者であるか否かを判定する。 The control unit 14 determines, for example, whether the user is a registrant by comparing the fingerprint of the operation finger that operates the operation button read by the biometric information sensor 10 with the template used for fingerprint authentication.
制御部１４は、例えば、指紋、静脈、顔画像、虹彩などの登録者の生体情報１１のテンプレートと登録者名とを関連付けてテンプレート情報１５として記憶している。 The control unit 14 stores a template of the registrant's biometric information 11 such as a fingerprint, a vein, a face image, and an iris and the registrant's name as template information 15, for example.
指紋を読み取る場合は、例えば、光学式、静電容量式、電界強度測定式、感圧式及び感熱式などの指紋パターンを読み取るように構成されたセンサを用いて行われる。 When a fingerprint is read, for example, a sensor configured to read a fingerprint pattern such as an optical type, a capacitance type, an electric field intensity measurement type, a pressure-sensitive type, and a heat-sensitive type is used.
操作指や手の平の静脈を読み取る場合は、例えば、照射した近赤外線の反射に基づいて静脈パターンを読み取るように構成されたセンサを用いて行われる。 Reading a vein of the operating finger or the palm is performed, for example, using a sensor configured to read a vein pattern based on the reflection of irradiated near infrared rays.
顔画像を取得する場合は、例えば、撮像された対象に複数の計測点を設け、この計測点の深度に基づいて対象の凹凸形状を読み取るように構成されたセンサを用いて行われる。 When acquiring a face image, for example, a plurality of measurement points are provided on the imaged target, and a sensor configured to read the uneven shape of the target based on the depth of the measurement point is used.
虹彩を読み取る場合は、例えば、赤外線を照射して撮像した画像を画像処理して虹彩を読み取るように構成されたセンサを用いて行われる。 Reading the iris is performed, for example, using a sensor configured to read the iris by performing image processing on an image captured by irradiating infrared rays.
（頻度情報生成部１２の構成）
頻度情報生成部１２は、例えば、図１Ａ及び図２Ａに示すように、識別情報Ｓ４に基づいて頻度情報１３を生成するように構成されている。この頻度情報１３は、例えば、生体認証された登録者ごとの認証回数（認証が成立した回数）の情報である。 (Configuration of Frequency Information Generation Unit 12)
Frequency information generating unit 12, for example, as shown in FIGS. 1A and 2A, and is configured to generate frequency information 13 based on the identification information S 4. The frequency information 13 is, for example, information on the number of times of authentication (the number of times of successful authentication) for each biometrically-registered registrant.
図２Ａに示す頻度情報１３は、一例として、登録者Ａ～登録者Ｅ、つまり５人のユーザのテンプレートが車両に登録されており、登録者Ａの認証回数が３回、登録者Ｂの認証回数が１回、登録者Ｃの認証回数が２回、登録者Ｄの認証回数が５回、登録者Ｅの認証回数が０回となっている。つまり頻度情報１３は、認証された頻度、言い換えるなら車両を利用した頻度を示している。 As an example, the frequency information 13 shown in FIG. 2A indicates that registrants A to E, that is, templates of five users are registered in the vehicle, the number of authentications of registrant A is three, and the number of authentications of registrant B is three. The number of times is one, the number of authentications of registrant C is two, the number of authentications of registrant D is five, and the number of authentications of registrant E is zero. That is, the frequency information 13 indicates the frequency of authentication, in other words, the frequency of using the vehicle.
制御部１４は、例えば、頻度情報１３のみに基づいて生体認証を行う場合、読み取った生体情報１１と頻度が高い登録者のテンプレートとを用いて生体認証を行う。つまり制御部１４は、例えば、頻度情報１３のみに基づいて生体認証を行う場合、読み取った生体情報１１と、登録者Ｄのテンプレート、登録者Ａのテンプレート、登録者Ｃのテンプレート、登録者Ｂのテンプレート、登録者Ｅのテンプレートの順に生体認証を行う。 For example, when performing biometric authentication based only on the frequency information 13, the control unit 14 performs biometric authentication using the read biometric information 11 and a template of a registrant who has high frequency. That is, for example, when performing biometric authentication based only on the frequency information 13, the control unit 14 reads the biometric information 11 and the template of the registrant D, the template of the registrant A, the template of the registrant C, and the Biometric authentication is performed in the order of the template and the template of the registrant E.
（制御部１４の構成）
制御部１４は、例えば、記憶されたプログラムに従って、取得したデータに演算、加工などを行うＣＰＵ（Central Processing Unit）、半導体メモリであるＲＡＭ（Random Access Memory）及びＲＯＭ（Read Only Memory）などから構成されるマイクロコンピュータである。このＲＯＭには、例えば、制御部１４が動作するためのプログラムが格納されている。ＲＡＭは、例えば、テンプレート情報１５、認証しきい値１６及び認証順位情報１７を格納すると共に、一時的に演算結果などを格納する記憶領域として用いられる。また制御部１４は、その内部にクロック信号を生成する手段を有し、このクロック信号に基づいて動作を行う。後述する認証方法は、このマイクロコンピュータが実行するプログラムとして提供されても良い。 (Configuration of the control unit 14)
The control unit 14 includes, for example, a CPU (Central Processing Unit) that performs calculations, processing, and the like on acquired data according to stored programs, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. Microcomputer. In the ROM, for example, a program for operating the control unit 14 is stored. The RAM is used, for example, as a storage area for storing the template information 15, the authentication threshold value 16, and the authentication order information 17, and for temporarily storing the calculation result and the like. Further, the control unit 14 has a means for generating a clock signal therein, and operates based on the clock signal. The authentication method described later may be provided as a program executed by the microcomputer.
テンプレート情報１５は、上述のように、生体情報１１の認証に用いる登録者ごとのテンプレートの情報である。 As described above, the template information 15 is template information for each registrant used for authentication of the biometric information 11.
制御部１４は、例えば、読み取られたユーザの生体情報１１の特徴点と、テンプレート情報１５のテンプレートと、を比較し、特徴点の位置、特徴点間の距離などに基づいて類似度を算出する。そして制御部１４は、類似度が認証しきい値１６以上であった場合、ユーザが登録者である、つまり生体認証が成立したことを示す認証情報Ｓ３を出力する。 The control unit 14 compares, for example, the read feature points of the biometric information 11 of the user with the template of the template information 15, and calculates the similarity based on the positions of the feature points, the distance between the feature points, and the like. . Then, the control unit 14, if the degree of similarity is not authenticated threshold 16 or more, the user is a registered person, that biometrics outputs the authentication information S 3 indicating that satisfied.
この認証しきい値１６は、一例として、特徴点の位置、特徴点間の距離などの比較対象の類似度の８０％として定義される。つまり制御部１４は、例えば、生体認証に使用する比較対象の数が８０個である場合、６４個以上の比較対象が一致すれば、ユーザが登録者であると判定する。 The authentication threshold value 16 is defined as, for example, 80% of the similarity of the comparison target such as the position of the feature point and the distance between the feature points. That is, for example, when the number of comparison targets used for biometric authentication is 80, and when 64 or more comparison targets match, the control unit 14 determines that the user is a registrant.
制御部１４は、例えば、認証が成立した場合、認証が成立したことを示す認証情報Ｓ３を車両制御部２０に出力する。車両制御部２０は、車両ＬＡＮ２１を介して認証情報Ｓ３が入力すると、認証成立に応じた制御を対象の電子機器に行う。本実施の形態では、一例として、認証情報Ｓ３に基づいて駆動装置の始動や電源の遷移を行う。 Control unit 14, for example, if the authentication is successful, and outputs the authentication information S 3 indicating that the authentication is successful to the vehicle control unit 20. The vehicle control unit 20, when via the vehicle LAN21 authentication information S 3 is inputted, performs control according to the authentication establishment to the target electronic equipment. In this embodiment, as an example, performs transition starting and power supply of the drive unit based on the authentication information S 3.
認証順位情報１７は、例えば、図２Ｂに示すように、認証の順位に関する情報である。制御部１４は、頻度情報１３のみに基づいて認証順位を定めるのではなく、車両に乗り込む前の段階で認証された登録者を認証順位の上位にする。 The authentication order information 17 is, for example, information on the order of authentication, as shown in FIG. 2B. The control unit 14 does not determine the authentication order based on only the frequency information 13 but sets the registrant who has been authenticated at the stage before getting into the vehicle in the higher order of the authentication order.
制御部１４は、例えば、図２Ａ及び図２Ｂに示すように、頻度情報１３に基づく車両使用の頻度が登録者Ｄ、登録者Ａ、登録者Ｃ、登録者Ｂ、登録者Ｅであり、第１の認証装置２３から出力された認証情報Ｓ２に基づいて識別された携帯機２２の登録者が登録者Ｂであった場合、頻度情報１３の順番ではなく、最上位を登録者Ｂとして登録者Ｂ、登録者Ｄ、登録者Ａ、登録者Ｃ、登録者Ｅの順で認証を行う。 For example, as shown in FIGS. 2A and 2B, the control unit 14 determines that the frequency of vehicle use based on the frequency information 13 is registrant D, registrant A, registrant C, registrant B, and registrant E. If the registrant of 1 of the authentication device 23 output from the authentication information S 2 the portable device 22 is identified based on were registrant B, rather than the order of the frequency information 13, registers the uppermost as registrant B Authentication is performed in the order of the registrant B, the registrant D, the registrant A, the registrant C, and the registrant E.
認証順位が登録順である場合、登録者Ａ～登録者Ｅの順に認証が行われるので、認証が成立する可能性が高い登録者Ｂ及び登録者Ｄの認証が行われるまで時間が掛かる。また認証順位が頻度順である場合、登録者Ｂの頻度が低いので、認証が成立する可能性が高い登録者Ｂ及び登録者Ｄの認証が行われるまで時間が掛かる。 When the authentication order is the registration order, the authentication is performed in the order of the registrants A to E. Therefore, it takes time until the authentication of the registrants B and D, which are highly likely to be successfully authenticated, is performed. In the case where the authentication order is in the order of frequency, since the frequency of the registrant B is low, it takes time until the registrants B and D, which are highly likely to be authenticated, are authenticated.
本実施の形態の認証順位は、携帯機２２の登録者Ｂ、及び車両を使用する頻度が高い登録者Ｄが一番目と二番目であるので、上述の場合と比べて、短い時間で認証が成立する可能性が高くなる。 In the authentication order of the present embodiment, the registrant B of the portable device 22 and the registrant D who frequently uses the vehicle are the first and second, so that the authentication is performed in a shorter time than in the above-described case. It is more likely to hold.
（認証システム２の構成）
認証システム２の車両制御部２０は、例えば、ＣＰＵ、ＲＡＭ及びＲＯＭなどから構成されるマイクロコンピュータである。このＲＯＭには、例えば、認証システム２が動作するためのプログラムが格納されている。またＲＡＭには、登録者を識別する登録者設定情報２００が記憶されている。 (Configuration of the authentication system 2)
The vehicle control unit 20 of the authentication system 2 is, for example, a microcomputer including a CPU, a RAM, a ROM, and the like. In the ROM, for example, a program for operating the authentication system 2 is stored. Also, registrant setting information 200 for identifying a registrant is stored in the RAM.
車両制御部２０は、例えば、車両に搭載された電子機器や車両ＬＡＮ２１を介した通信などを制御する。この車両ＬＡＮ２１は、一例として、ＣＡＮ（Controller Area Network）及びＬＩＮ（Local Interconnect Network）などの規格を用いた相互の通信を可能とするものである。 The vehicle control unit 20 controls, for example, electronic devices mounted on the vehicle and communication via the vehicle LAN 21. The vehicle LAN 21 enables, for example, mutual communication using standards such as CAN (Controller Area Network) and LIN (Local Interconnect Network).
この車両ＬＡＮ２１には、例えば、認証装置１、第１の認証装置２３、第２の認証装置２４、及び車載装置２５が電磁気的に接続されている。なお車両ＬＡＮ２１には、さらに複数の認証装置や複数の車載装置が接続されても良い。 For example, an authentication device 1, a first authentication device 23, a second authentication device 24, and a vehicle-mounted device 25 are electromagnetically connected to the vehicle LAN 21. Note that a plurality of authentication devices and a plurality of in-vehicle devices may be further connected to the vehicle LAN 21.
第１の認証装置２３は、上述のように、無線によって携帯機２２の登録者ＩＤを認証するように構成されている。第１の認証装置２３は、認証が成立すると、携帯機２２の登録者ＩＤの情報を含む認証情報Ｓ２を生成して車両ＬＡＮ２１を介して車両制御部２０に出力する。車両制御部２０は、車両ＬＡＮ２１を介して認証情報Ｓ２が入力すると、認証成立に応じた制御を対象の電子機器に行う。 As described above, the first authentication device 23 is configured to authenticate the registrant ID of the portable device 22 wirelessly. The first authentication apparatus 23, when the authentication is established, and generates the authentication information S 2 including information of a registrant ID of the portable device 22 outputs to the vehicle control unit 20 via the vehicle LAN 21. The vehicle control unit 20, when via the vehicle LAN21 authentication information S 2 is inputted, performs control according to the authentication establishment to the target electronic equipment.
第２の認証装置２４は、例えば、ＣＰＵ、ＲＡＭ及びＲＯＭなどから構成されるマイクロコンピュータである制御部を備えている。後述する認証方法は、このマイクロコンピュータが実行するプログラムとして提供されても良い。 The second authentication device 24 includes a control unit which is a microcomputer including, for example, a CPU, a RAM, a ROM, and the like. The authentication method described later may be provided as a program executed by the microcomputer.
第２の認証装置２４は、例えば、生体情報以外の情報２４０を用いた認証を行う。この生体情報以外の情報２４０とは、例えば、図２Ｃに示すように、筆圧、認証パターン、住所、パスワード、鍵、スマートフォンなどである。この生体情報以外の情報２４０は、例えば、認識パターンＡ及び認識パターンＢなどのように同種類の情報が複数登録されても良い。第２の認証装置２４は、認証が成立したことを示す認証情報Ｓ５を車両制御部２０に出力する。車両制御部２０は、車両ＬＡＮ２１を介して認証情報Ｓ５が入力すると、認証成立に応じた制御を対象の電子機器に行う。 The second authentication device 24 performs authentication using information 240 other than the biological information, for example. The information 240 other than the biometric information is, for example, a pen pressure, an authentication pattern, an address, a password, a key, a smartphone, and the like as shown in FIG. 2C. As the information 240 other than the biological information, a plurality of information of the same type such as a recognition pattern A and a recognition pattern B may be registered. The second authentication device 24 outputs the authentication information S 5 indicating that the authentication is successful to the vehicle control unit 20. The vehicle control unit 20, the authentication information S 5 via the vehicle LAN21 inputs, performs control according to the authentication establishment to the target electronic equipment.
第２の認証装置２４は、これらの生体情報以外の情報２４０を登録者ごとに有している。また第２の認証装置２４は、例えば、車両ＬＡＮ２１を介して車両制御部２０から識別情報Ｓ４を取得すると、第１の認証装置２３によって認証された登録者を認証順位の一番目とし、この認証順位の二番目以降を自身が認証した登録者の認証の頻度に基づいて定める。 The second authentication device 24 has information 240 other than the biometric information for each registrant. The second authentication apparatus 24, for example, when through the vehicle LAN21 acquires identification information S 4 from the vehicle control unit 20, an authenticated registrant as one th authentication rank by the first authentication apparatus 23, the The second and subsequent authentication orders are determined based on the authentication frequency of the registrant who has authenticated themselves.
つまり認証システム２は、第１の認証装置２３の認証結果に基づいて、接続された生体情報を用いて認証する認証装置（例えば認証装置１）、及び生体情報以外を用いて認証する認証装置（例えば第２の認証装置２４）の認証順位を、第１の認証装置２３が認証した登録者が一番目となるように変更する。 That is, based on the authentication result of the first authentication device 23, the authentication system 2 authenticates using the connected biometric information (for example, the authentication device 1), and an authentication device that authenticates using something other than the biometric information ( For example, the authentication order of the second authentication device 24) is changed so that the registrant authenticated by the first authentication device 23 becomes the first.
車載装置２５は、例えば、この識別情報Ｓ４に基づいて識別された登録者が設定した設定を実行する。車載装置２５がシート装置である場合、例えば、識別情報Ｓ４により識別された登録者が設定したシートの位置、角度などになるように調整する。また車載装置２５が空調装置である場合、例えば、登録者が設定した設定温度や風量などになるように調整する。 Vehicle device 25 executes, for example, set the identified registrant based on the identification information S 4 is set. If vehicle device 25 is a seat apparatus, for example, the position of the sheet registrant identified by the identification information S 4 are set, adjusted to be such an angle. When the in-vehicle device 25 is an air conditioner, for example, the adjustment is performed so that the temperature or the air volume is set by the registrant.
以下に本実施の形態の認証装置１及び認証システム２の認証順位の更新に関する動作の一例を図３のタイミングチャートに従って説明する。 Hereinafter, an example of an operation related to updating the authentication order of the authentication device 1 and the authentication system 2 according to the present embodiment will be described with reference to the timing chart of FIG.
（動作）
ユーザが車両に乗り込むため、携帯機２２を携帯して車両に近づくと、第１の認証装置２３と携帯機２２との通信が行われ、認証が開始される（Ｓｔｅｐ１）。 (motion)
When the user gets into the vehicle and carries the portable device 22 and approaches the vehicle, communication between the first authentication device 23 and the portable device 22 is performed, and authentication is started (Step 1).
具体的には、第１の認証装置２３は、車両に近づいた、つまり通信圏内に入った携帯機２２と無線通信を行い、携帯機２２から取得したＩＤ情報Ｓ１と登録情報２３０とに基づいて携帯機２２が登録されているか確認する。第１の認証装置２３は、認証が成立すると（Ｓｔｅｐ２）、認証された登録者の情報（認証情報Ｓ２）を、車両ＬＡＮ２１を介して車両制御部２０に送信する。 Specifically, the first authentication device 23 performs wireless communication with the portable device 22 approaching the vehicle, that is, within the communication range, and based on the ID information S 1 and the registration information 230 acquired from the portable device 22. To check whether the portable device 22 is registered. When the authentication is established (Step 2), the first authentication device 23 transmits the information of the authenticated registrant (authentication information S 2 ) to the vehicle control unit 20 via the vehicle LAN 21.
次に車両制御部２０は、車両のドアをアンロックすると共に、入力した認証情報Ｓ２に基づいて登録者を識別して識別情報Ｓ４を生成し、認証装置１、第２の認証装置２４などに出力する（Ｓｔｅｐ３）。 Then the vehicle control unit 20 is configured to unlock the doors of the vehicle, to identify the registrant generates identification information S 4 based on the authentication information S 2 inputted, the authentication device 1, the second authentication apparatus 24 And the like (Step 3).
認証装置１の制御部１４は、入力した識別情報Ｓ４に基づいて頻度情報１３を更新する（Ｓｔｅｐ４）と共に、更新した頻度情報１３において識別された登録者（第１の登録者）の認証順位を一番目とし、二番目以降を頻度の順番として認証順位を更新する（Ｓｔｅｐ５）。そして制御部１４は、認証順位を更新した認証順位情報１７に基づいて生体認証を行う。 The control unit 14 of the authentication device 1 updates the frequency information 13 based on the input identification information S4 (Step 4 ), and authenticates the registrant (first registrant) identified in the updated frequency information 13. Is the first, and the second and the subsequent are set as the order of the frequency, and the authentication order is updated (Step 5). Then, the control unit 14 performs biometric authentication based on the authentication order information 17 whose authentication order is updated.
また第２の認証装置２４は、入力した識別情報Ｓ４に基づいて頻度情報１３を更新する（Ｓｔｅｐ６）と共に、更新した頻度情報１３において識別された登録者（第１の登録者）の認証順位を一番目とし、二番目以降を頻度の順番として認証順位を更新する（Ｓｔｅｐ７）。そして第２の認証装置２４は、更新した認証順位に基づいて生体認証を行う。 The second authentication apparatus 24, the authentication ranking based on the identification information S 4 inputted to update the frequency information 13 with (Step6), identified registrant in the frequency information 13 has been updated (the first subscriber) Is the first, and the second and subsequent frequencies are set in the order of frequency, and the authentication order is updated (Step 7). Then, the second authentication device 24 performs biometric authentication based on the updated authentication order.
（第１の実施の形態の効果）
本実施の形態に係る認証装置１は、認証に掛かる時間を抑制することができる。具体的には、認証装置１は、携帯機２２を使用した者が携帯機２２の登録者でない場合であっても、二番目以降は頻度に応じて生体認証がなされるので、この構成を採用しない場合と比べて、認証順位の一番目と二番目において認証が成立する確率が高く、認証時間の増加を抑制することができる。この認証装置１は、認証に時間が掛かる生体認証を行うので、効果的に認証に掛かる時間を抑制することができる。 (Effects of the First Embodiment)
The authentication device 1 according to the present embodiment can reduce the time required for authentication. Specifically, even if the person who uses the portable device 22 is not a registrant of the portable device 22, the authentication device 1 performs the biometric authentication according to the frequency after the second device. Compared with the case where no authentication is performed, the probability of authentication being established in the first and second authentication orders is higher, and an increase in authentication time can be suppressed. Since the authentication device 1 performs biometric authentication requiring a long time for authentication, the time required for the authentication can be effectively suppressed.
認証装置１は、携帯機２２の登録者と携帯機２２を使用する者が異なった場合であっても良く車両を利用する、つまり頻度が高い登録者の認証に掛かる時間を抑制することができる。 The authentication device 1 may use a vehicle even if the registrant of the portable device 22 and the person using the portable device 22 are different, that is, it is possible to suppress the time required to authenticate a registrant with high frequency. .
認証システム２は、複数の認証装置の認証順位を上述のように設定させることができるので、第１の認証装置２３による認証後に複数回認証が必要な場合などに効果的に認証時間の短縮を行うことができる。 Since the authentication system 2 can set the authentication order of a plurality of authentication devices as described above, it is possible to effectively reduce the authentication time when the authentication by the first authentication device 23 requires authentication a plurality of times. It can be carried out.
認証装置１及び認証システム２は、第１の認証装置２３による認証が、携帯機２２が車両の外にある間に行われ、車両に乗り込んで次の認証を行うまでに認証順位を設定することができるので、この構成を採用しない場合と比べて、効果的に認証時間の短縮を行うことができる。 The authentication device 1 and the authentication system 2 set the authentication order by the time the authentication by the first authentication device 23 is performed while the portable device 22 is outside the vehicle and the user gets into the vehicle and performs the next authentication. Therefore, the authentication time can be effectively reduced as compared with the case where this configuration is not adopted.
[第２の実施の形態]
第２の実施の形態は、前回認証した登録者を認証順位の上位にする点で第１の実施の形態と異なっている。 [Second embodiment]
The second embodiment is different from the first embodiment in that the registrant who has been authenticated last time is ranked higher in the authentication order.
以下に第２の実施の形態に係る認証装置１の一例について各図を参照しながら説明する。なお以下に記載する実施の形態において、第１の実施の形態と同じ機能及び構成を有する部分は、第１の実施の形態と同じ符号を付し、その説明は省略するものとする。 Hereinafter, an example of the authentication device 1 according to the second embodiment will be described with reference to the drawings. In the embodiments described below, portions having the same functions and configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.
まず制御部１４は、例えば、図４Ａ～図４Ｃに示すように、他の認証装置（第１の認証装置２３）によって認証された第１の登録者（登録者Ｂ）を認証順位の一番目とし、二番目以降をそれまで認証された登録者の頻度に基づいて定める。そして制御部１４は、例えば、図４Ａ～図４Ｃに示すように、さらに他の認証装置による認証の直前に自ら行った認証が成立した第２の登録者（登録者Ｅ）を、認証順位の一番目又は二番目とし、三番目以降をそれまでの頻度に基づいて定めるように構成されている。 First, for example, as shown in FIGS. 4A to 4C, the control unit 14 assigns the first registrant (registrant B) authenticated by another authentication device (first authentication device 23) to the first authentication order. And the second and subsequent ones are determined based on the frequency of registrants who have been authenticated so far. Then, as shown in FIG. 4A to FIG. 4C, for example, the control unit 14 assigns the second registrant (registrant E) for which the authentication performed by himself / herself immediately before the authentication by another authentication device has been established to the authentication order. It is configured to be the first or second, and to determine the third or later based on the frequency up to that.
図４Ｂは、一番目を第１の登録者（登録者Ｂ）、二番目を第２の登録者（登録者Ｅ）、三番目以降をそれまでの頻度に基づいて定められた認証順位を示している。 FIG. 4B shows the authentication order determined based on the first registrant (registrant B), the second registrant (registrant E), the third registrant based on the frequency up to then. ing.
図４Ｃは、一番目を第２の登録者（登録者Ｅ）、二番目を第１の登録者（登録者Ｂ）、三番目以降をそれまでの頻度に基づいて定められた認証順位を示している。 FIG. 4C shows an authentication order determined based on the first registrant (registrant E), the second registrant (registrant B), the third registrant based on the frequency up to the second registrant (registrant B). ing.
なお認証順位の更新は、第１の登録者、第２の登録者の順番で更新しても良いし、第２の登録者、第１の登録者の順番で更新しても良い。本実施の形態では、制御部１４は、他の認証装置による認証の直前に自ら行った認証が成立した第２の登録者を、認証順位の二番目とし、三番目以降をそれまでの頻度に基づいて定める場合について説明する。 The authentication order may be updated in the order of the first registrant and the second registrant, or may be updated in the order of the second registrant and the first registrant. In the present embodiment, the control unit 14 sets the second registrant whose authentication performed immediately before authentication by another authentication device has been established as the second in the authentication order, and sets the second and subsequent registrants to the frequency up to that. A description will be given of a case determined based on the above.
以下に本実施の形態の認証装置１及び認証システム２の動作の一例を図５のタイミングチャートに従って説明する。 Hereinafter, an example of the operation of the authentication device 1 and the authentication system 2 of the present embodiment will be described with reference to the timing chart of FIG.
（動作）
認証装置１の制御部１４は、前回の認証、つまり最後に行われた認証が成立した登録者を記憶する（Ｓｔｅｐ１０）。同様に、第２の認証装置２４は、前回の認証、つまり最後に行われた認証が成立した登録者を記憶する（Ｓｔｅｐ１６）。 (motion)
The control unit 14 of the authentication device 1 stores the registrant for whom the previous authentication, that is, the authentication performed last is established (Step 10). Similarly, the second authentication device 24 stores the registrant for whom the previous authentication, that is, the authentication performed last is established (Step 16).
その後、ユーザが車両に乗り込むため、携帯機２２を携帯して車両に近づくと、第１の認証装置２３と携帯機２２との通信が行われ、認証が開始される（Ｓｔｅｐ１２）。 Thereafter, when the user gets into the vehicle and carries the portable device 22 and approaches the vehicle, communication between the first authentication device 23 and the portable device 22 is performed, and authentication is started (Step 12).
次に第１の認証装置２３は、認証が成立すると（Ｓｔｅｐ１３）、認証された登録者の情報（認証情報Ｓ２）を、車両ＬＡＮ２１を介して車両制御部２０に送信する。 Next, when the authentication is established (Step 13), the first authentication device 23 transmits information of the authenticated registrant (authentication information S 2 ) to the vehicle control unit 20 via the vehicle LAN 21.
次に車両制御部２０は、車両のドアをアンロックすると共に、入力した認証情報Ｓ２に基づいて登録者を識別して識別情報Ｓ４を生成し、認証装置１、第２の認証装置２４などに出力する（Ｓｔｅｐ１４）。 Then the vehicle control unit 20 is configured to unlock the doors of the vehicle, to identify the registrant generates identification information S 4 based on the authentication information S 2 inputted, the authentication device 1, the second authentication apparatus 24 And the like (Step 14).
認証装置１の制御部１４は、入力した識別情報Ｓ４に基づいて頻度情報１３を更新する（Ｓｔｅｐ１５）。そして制御部１４は、例えば、図４Ａ及び図４Ｂに示すように、第１の認証装置２３によって認証された第１の登録者（登録者Ｂ）を認証順位の一番目とすると共に、ステップ１０において記憶していた第１の認証装置２３による認証の直前に自ら行った認証が成立した第２の登録者（登録者Ｅ）を、認証順位の二番目とし、三番目以降をそれまでの頻度に基づいて定め、認証順位を更新する（Ｓｔｅｐ１６）。そして制御部１４は、認証順位を更新した認証順位情報１７に基づいて生体認証を行う。 Control unit 14 of the authentication apparatus 1 updates the frequency information 13 based on the identification information S 4 inputted (Step 15). Then, the control unit 14 sets the first registrant (registrant B) authenticated by the first authentication device 23 as the first in the authentication order, as shown in FIG. 4A and FIG. The second registrant (registrant E) whose authentication performed immediately before the authentication by the first authentication device 23, stored in the above, has been established as the second in the order of authentication, and the third and subsequent ones have the same frequency. And the authentication order is updated (Step 16). Then, the control unit 14 performs biometric authentication based on the authentication order information 17 whose authentication order is updated.
また第２の認証装置２４は、入力した識別情報Ｓ４に基づいて頻度情報１３を更新する（Ｓｔｅｐ１７）。そして第２の認証装置２４は、第１の認証装置２３によって認証された第１の登録者を認証順位の一番目とすると共に、ステップ１１において記憶していた第１の認証装置２３による認証の直前に自ら行った認証が成立した第２の登録者を、認証順位の二番目とし、三番目以降をそれまでの頻度に基づいて定め、認証順位を更新する（Ｓｔｅｐ１８）。そして第２の認証装置２４は、更新した認証順位に基づいて生体認証を行う。 The second authentication apparatus 24 updates the frequency information 13 based on the identification information S 4 inputted (Step 17). Then, the second authentication device 24 sets the first registrant authenticated by the first authentication device 23 as the first in the authentication order, and performs the authentication of the first authentication device 23 stored in step 11 by the first authentication device 23. The second registrant whose authentication performed immediately before himself has been established is determined as the second in the authentication order, the third and subsequent registrants are determined based on the frequency up to that time, and the authentication order is updated (Step 18). Then, the second authentication device 24 performs biometric authentication based on the updated authentication order.
（第２の実施の形態の効果）
認証装置１は、携帯機２２を使用した者が携帯機２２の登録者でない場合であっても、一番目から二番目までが第１の認証装置２３によって認証された登録者であり、認証装置１によって前回認証された登録者であり、さらに三番目以降は頻度に応じて生体認証がなされるので、この構成を採用しない場合と比べて、認証順位の一番目から三番目までに認証が成立する確率が高く、認証時間の増加を抑制することができる。この認証装置１は、認証に時間が掛かる生体認証を行うので、効果的に認証に掛かる時間を抑制することができる。 (Effect of Second Embodiment)
Even if the person who uses the portable device 22 is not a registrant of the portable device 22, the first to second registrants are the registrants who have been authenticated by the first authentication device 23. 1 is the registrant who was authenticated last time, and the third and subsequent biometrics are performed according to the frequency. Therefore, compared to the case where this configuration is not adopted, the authentication is established from the first to the third in the authentication order. The probability of performing authentication is high, and an increase in authentication time can be suppressed. Since the authentication device 1 performs biometric authentication requiring a long time for authentication, the time required for the authentication can be effectively suppressed.
認証システム２は、複数の認証装置の認証順位を上述のように設定させることができるので、第１の認証装置２３による認証後に複数回認証が必要な場合などに効果的に認証時間の短縮を行うことができる。 Since the authentication system 2 can set the authentication order of a plurality of authentication devices as described above, it is possible to effectively reduce the authentication time when the authentication by the first authentication device 23 requires authentication a plurality of times. It can be carried out.
なお他の実施の形態としての認証方法は、他の認証装置によって認証された第１の登録者を認証順位の一番目とし、二番目以降をそれまで認証された登録者の頻度に基づいて定め、定めた認証順位に基づいて認証を行う、ことを含んでいる。 In an authentication method according to another embodiment, a first registrant authenticated by another authentication device is set as the first authentication order, and the second and subsequent registrants are determined based on the frequency of registrants authenticated so far.

May be.
そして認証方法は、上記の自ら行った認証が生体情報を用いた認証、又は生体情報以外を用いた認証である。 In the authentication method, the authentication performed by the user is authentication using biometric information or authentication using something other than biometric information.
この認証方法は、例えば、コンピュータが実行するプログラム、ＡＳＩＣ（Application Specific Integrated Circuit）及びＦＰＧＡ（Field Programmable Gate Array）などによって実現されても良い。 This authentication method may be realized by, for example, a program executed by a computer, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.
またさらに他の実施の形態として、制御部１４は、頻度が最も高い登録者、第１の認証装置２３によって認証成立した登録者を組み合わせて一番目と二番目に配置して認証順位を更新しても良い。さらに制御部１４は、頻度が最も高い登録者、第１の認証装置２３によって認証成立した登録者、第１の認証装置２３による認証の直前に自ら行った認証が成立した登録者を組み合わせて一番目～三番目に配置して認証順位を更新しても良い。 As still another embodiment, the control unit 14 updates the authentication order by arranging the registrant with the highest frequency and the registrant who has been authenticated by the first authentication device 23 in the first and second positions in combination. May be. Further, the control unit 14 combines the registrant with the highest frequency, the registrant who has been authenticated by the first authentication device 23, and the registrant who has performed authentication immediately before the authentication by the first authentication device 23. The authentication order may be updated by arranging the authentication order in the third to third places.
以上述べた少なくとも１つの実施の形態によれば、認証に掛かる時間を抑制することが可能となる。 According to at least one embodiment described above, it is possible to reduce the time required for authentication.
