　まず、利用者情報の登録の機能を説明する。利用者情報は、例えば認証システム１の管理者によって登録される。 First, the function of registering user information will be explained. The user information is registered by the administrator of the authentication system 1, for example.
　管理者は、登録する利用者情報を利用者情報処理部１０に入力する。利用者情報処理部１０は、利用者情報データベースに入力された利用者情報を登録する。入力された利用者情報が既に登録されている利用者３を表す場合に、利用者情報処理部１０は、利用者情報データベースに入力された利用者情報を更新してもよい。例えば登録された利用者情報が表す利用者３が制限区域に入域できる利用者３である場合に、利用者情報処理部１０は、認証情報を認証情報処理部２２に送信する。送信される認証情報は、例えば当該利用者３が所持するスマートデバイス４の識別情報と、制限区域を識別する情報との組である。 The administrator inputs the user information to be registered in the user information processing unit 10. The user information processing unit 10 registers the user information input to the user information database. When the input user information represents the already registered user 3, the user information processing unit 10 may update the user information input to the user information database.

When the acquired authentication information is information for changing the already registered authentication information, the authentication information processing unit 22 may update the authentication information.
　次に、利用者３の認証の機能を説明する。 Next, the authentication function of user 3 will be explained.
　通信制御部２０は、送信部１８にトリガー信号の送信を指示する信号を出力する。送信部１８は、トリガー信号をＢＬＥ規格の信号により送信する。トリガー信号は、スマートデバイス４の認証アプリケーションの動作のトリガーとなる信号である。 The communication control unit 20 outputs a signal instructing the transmission unit 18 to transmit a trigger signal. The transmitter 18 transmits the trigger signal as a BLE standard signal. The trigger signal is a signal that triggers the operation of the authentication application of the smart device 4.
　通信制御部２０は、形成部１７に変動磁界の形成を指示する信号を出力する。形成部１７は、例えば次のように変動磁界を形成する。形成部１７は、例えば２つの形成方法を交互に切り替えて変動磁界を形成する。 The communication control unit 20 outputs a signal instructing the formation unit 17 to form a fluctuating magnetic field. The forming unit 17 forms the variable magnetic field as follows, for example. The forming unit 17 forms a fluctuating magnetic field by alternately switching, for example, two forming methods.
　形成部１７は、２つの形成方法の一方として、放射部２４から長波を放射することによって変動磁界を形成する。放射部２４が放射する長波の周波数は、例えば１００ｋＨｚである。放射部２４は、照合エリア７の内部全体において磁界成分の振幅が閾値以上となる出力で長波を放射する。 The forming unit 17 forms a fluctuating magnetic field by emitting a long wave from the emitting unit 24 as one of two forming methods. The frequency of the long wave radiated by the radiator 24 is, for example, 100 kHz. The radiating unit 24 radiates a long wave with an output in which the amplitude of the magnetic field component is equal to or larger than a threshold value in the entire inside of the matching area 7.
　形成部１７は、２つの形成方法の他方として、放射部２４が放射する長波を変調部２５に変調させることによって変動磁界を形成する。変調部２５は、例えば振幅変調によって放射部２４が放射する長波を変調させる。スマートデバイス４に搭載される磁気センサー１３として複数の種類の磁気センサー１３が想定される場合に、変調部２５は、想定される磁気センサー１３の上限周波数のうち、最も低い周波数より低い周波数に長波を変調させる。変調部２５は、例えば１０Ｈｚ以下の周波数に長波を変調させる。 As the other of the two forming methods, the forming unit 17 forms a fluctuating magnetic field by modulating the long wave emitted by the emitting unit 24 by the modulating unit 25. The modulator 25 modulates the long wave emitted by the radiator 24 by amplitude modulation, for example. When a plurality of types of magnetic sensors 13 are assumed as the magnetic sensor 13 mounted on the smart device 4, the modulation unit 25 sets the long wave to a frequency lower than the lowest frequency among the upper limit frequencies of the assumed magnetic sensor 13. To modulate. The modulator 25 modulates a long wave to a frequency of 10 Hz or less, for example.
　スマートデバイス４は、インストールされている認証アプリケーションによって認証システム１の認証についての動作をする。 The smart device 4 operates for authentication of the authentication system 1 according to the installed authentication application.
　受信部１２がトリガー信号を受信する場合に、通信制御部１４は、磁気センサー１３が検出する変動磁界の強さが閾値以上であるかを判定する。通信制御部１４は、例えば磁気センサー１３が検出する磁界を時間的に定常な成分と時間に対して変動する成分とに分離する。通信制御部１４は、定常な成分を地磁気によるものと判定する。通信制御部１４は、変動する成分を変動磁界によるものと判定する。通信制御部１４は、変動磁界の例えば振幅の大きさによって、変動磁界の強さが閾値以上であるかを判定する。 When the receiving unit 12 receives the trigger signal, the communication control unit 14 determines whether the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is equal to or more than a threshold value. The communication control unit 14 separates the magnetic field detected by the magnetic sensor 13, for example, into a temporally stationary component and a temporally varying component. The communication control unit 14 determines that the stationary component is due to geomagnetism. The communication control unit 14 determines that the varying component is due to the varying magnetic field. The communication control unit 14 determines whether the strength of the fluctuating magnetic field is equal to or greater than a threshold value, for example, based on the magnitude of the fluctuating magnetic field.
　磁気センサー１３が検出する変動磁界の強さが閾値未満であるときに、通信制御部１４は、送信部１１に照合情報を送信させない。例えばスマートデバイス４が照合エリア７の外側にある場合に、磁気センサー１３が検出する変動磁界の強さが閾値未満になる。 When the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is less than the threshold value, the communication control unit 14 does not cause the transmission unit 11 to transmit the collation information. For example, when the smart device 4 is outside the verification area 7, the strength of the fluctuating magnetic field detected by the magnetic sensor 13 becomes less than the threshold value.
　一方、スマートデバイス４が照合エリア７の内側にある場合に、磁気センサー１３が検出する変動磁界の強さは閾値以上である。このときに、通信制御部１４は、送信部１１に照合情報の送信を指示する信号を出力する。送信部１１は、ＢＬＥ規格によって受信部１９との接続を確立する。このとき、送信部１１および受信部１９は、利用者３の操作を必要としない方法により通信する。利用者３の操作を必要としない方法は、例えばＢＬＥ規格において、ペアリングの認証操作を必要としないセキュリティレベルによる通信である。その後、送信部１１は、受信部１９に照合情報を送信する。 On the other hand, when the smart device 4 is inside the matching area 7, the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is equal to or higher than the threshold value. At this time, the communication control unit 14 outputs a signal instructing the transmission unit 11 to transmit the matching information. The transmitter 11 establishes a connection with the receiver 19 according to the BLE standard. At this time, the transmission unit 11 and the reception unit 19 communicate by a method that does not require the operation of the user 3. A method that does not require the operation of the user 3 is communication with a security level that does not require a pairing authentication operation in the BLE standard, for example. After that, the transmission unit 11 transmits the matching information to the reception unit 19.
　通信制御部２０は、受信部１９が照合情報を表す無線信号を受信したときに、照合情報を取得する。通信制御部２０は、取得した照合情報が例えば暗号化されている場合に、復号化の処理を行う。通信制御部２０は、照合情報からスマートデバイス４の識別情報を抽出する。通信制御部２０は、抽出した識別情報を認証部２３に出力する。 The communication control unit 20 acquires the matching information when the receiving unit 19 receives the wireless signal representing the matching information. The communication control unit 20 performs a decryption process when the acquired matching information is encrypted, for example. The communication control unit 20 extracts the identification information of the smart device 4 from the collation information. The communication control unit 20 outputs the extracted identification information to the authentication unit 23.
　認証部２３は、認証情報を認証情報データベースから取得する。認証部２３は、取得した認証情報および識別情報に基づいて、当該識別情報に識別されるスマートデバイス４を所持する利用者３が認証の条件を満たすかを判定する。当該利用者３が認証の条件を満たすと認証部２３が判定する場合に、認証部２３は、認証信号を電気錠６、エレベーター制御盤２８、および校正装置２９に出力する。一方、当該利用者３が認証の条件を満たさないと認証部２３が判定する場合に、認証部２３は、認証信号を出力しない。 The authentication unit 23 acquires the authentication information from the authentication information database. The authentication unit 23 determines, based on the acquired authentication information and identification information, whether the user 3 having the smart device 4 identified by the identification information satisfies the authentication condition. When the authentication unit 23 determines that the user 3 satisfies the authentication condition, the authentication unit 23 outputs the authentication signal to the electric lock 6, the elevator control panel 28, and the calibration device 29. On the other hand, when the authentication unit 23 determines that the user 3 does not satisfy the authentication condition, the authentication unit 23 does not output the authentication signal.
　電気錠６は、認証信号が入力されたときに、扉２を解錠する。利用者３は、扉２を通行して制限区域に入域できるようになる。電気錠６は、例えば扉２を解錠したあと予め定められた時間が経過したときに、扉２を施錠する。あるいは、電気錠６は、認証信号が入力されたときに、解錠されている扉２を施錠してもよい。 The electric lock 6 unlocks the door 2 when an authentication signal is input. The user 3 can pass through the door 2 and enter the restricted area. The electric lock 6 locks the door 2 when a predetermined time elapses after unlocking the door 2, for example. Alternatively, the electric lock 6 may lock the unlocked door 2 when the authentication signal is input.
　エレベーター制御盤２８は、認証信号が入力されたときに、エレベーターの呼びを登録する。当該呼びは、例えば認証装置５が設けられる階からの乗場呼びとして登録される。エレベーター制御盤２８は、登録された呼びに従ってエレベーターのかごを認証装置５が設けられる階に走行させる。 The elevator control panel 28 registers the elevator call when the authentication signal is input. The call is registered as a landing call from the floor where the authentication device 5 is installed, for example. The elevator control panel 28 causes the elevator car to travel to the floor where the authentication device 5 is installed according to the registered call.
　校正装置２９は、認証信号が入力されたときに、認証された利用者３の位置情報を認証装置５の位置によって校正する。校正装置２９は、当該利用者３の位置情報を、例えば照合エリア７の内部の位置に校正する。校正装置２９は、校正した後の位置情報をスマートデバイス４に送信する。スマートデバイス４は、校正装置２９から受信した位置情報によって現在の利用者３の位置情報を更新する。 The calibrating device 29 calibrates the position information of the authenticated user 3 with the position of the authentication device 5 when the authentication signal is input. The calibration device 29 calibrates the position information of the user 3 to a position inside the matching area 7, for example. The calibrating device 29 transmits the calibrated position information to the smart device 4. The smart device 4 updates the current position information of the user 3 with the position information received from the calibration device 29.
　続いて、図３を用いて変調部２５による変調の例を説明する。
　図３は、実施の形態１に係る認証システムにおける変調の例を示す図である。 Subsequently, an example of modulation by the modulator 25 will be described with reference to FIG.

　図３において、変調部２５の振幅変調によって１００ｋＨｚから６．６Ｈｚに変調された電磁波による磁界の時間変化が示される。図３の横軸は、時間を表す。図３の縦軸は、磁界の強さを表す。なお、図３において、１００ｋＨｚの搬送波は、図示のために１００ｋＨｚより低い周波数で描かれている。 In FIG. 3, the time change of the magnetic field due to the electromagnetic wave modulated from 100 kHz to 6.6 Hz by the amplitude modulation of the modulator 25 is shown. The horizontal axis of FIG. 3 represents time. The vertical axis of FIG. 3 represents the strength of the magnetic field. In FIG. 3, the carrier wave of 100 kHz is drawn at a frequency lower than 100 kHz for the sake of illustration.
　搬送波は、放射部２４が放射する長波である。変調部２５は、放射部２４が放射する長波の出力を強弱の２段階で変化させる。変調部２５は、６５ｍｓの間、強い出力で放射部２４に長波を出力させる。変調部２５は、その後、８５ｍｓの間、弱い出力で放射部２４に長波を出力させる。変調部２５は、１５０ｍｓの周期でこれを繰り返す。１５０ｍｓの周期は、６．６Ｈｚの周波数に対応する。このため、放射部２４が放射する長波の出力の包絡線は、６．６Ｈｚの矩形波となる。 The carrier wave is a long wave radiated by the radiation unit 24. The modulation unit 25 changes the output of the long wave radiated by the radiation unit 24 in two levels of strength. The modulator 25 causes the radiator 24 to output a long wave with a strong output for 65 ms. The modulator 25 then causes the radiator 24 to output a long wave with a weak output for 85 ms. The modulator 25 repeats this at a cycle of 150 ms. A period of 150 ms corresponds to a frequency of 6.6 Hz. Therefore, the envelope of the output of the long wave radiated by the radiating section 24 becomes a rectangular wave of 6.6 Hz.

Then, the user information processing unit 10 transmits the authentication information to the authentication information processing unit 22 of the authentication device 5. After that, the operation of the authentication system 1 proceeds to step S13.

Further, the communication control unit 20 instructs the forming unit 17 to form the fluctuating magnetic field. After that, the operation of the authentication device 5 proceeds to step S22.
　ステップＳ２２において、送信部１８は、トリガー信号を送信する。その後、認証装置５の動作は、ステップＳ２３に進む。 In step S22, the transmission unit 18 transmits a trigger signal. After that, the operation of the authentication device 5 proceeds to step S23.
　ステップＳ２３において、形成部１７は、変動磁界を形成する。その後、認証装置５の動作は、ステップＳ２４に進む。形成部１７は、例えば通信制御部２０から変動磁界の形成を終了する指示があるまで、変動磁界の形成を継続してもよい。 In step S23, the forming unit 17 forms a fluctuating magnetic field. Then, the operation of the authentication device 5 proceeds to step S24.

If the determination result is NO, the operation of the authentication device 5 proceeds to step S21. If the determination result is YES, the operation of the authentication device 5 proceeds to step S25.
　ステップＳ２５において、通信制御部２０は、受信部１９が受信した照合情報から識別情報を抽出する。その後、認証装置５の動作は、ステップＳ２６に進む。 In step S25, the communication control unit 20 extracts the identification information from the matching information received by the receiving unit 19. Then, the operation of the authentication device 5 proceeds to step S26.
　ステップＳ２６において、認証部２３は、認証情報および通信制御部２０が抽出した識別情報に基づいて、認証の条件が満たされるかを判定する。判定結果がＮＯである場合に、認証装置５の動作は、ステップＳ２１に進む。判定結果がＹＥＳである場合に、認証装置５の動作は、ステップＳ２７に進む。 In step S26, the authentication unit 23 determines whether the authentication condition is satisfied, based on the authentication information and the identification information extracted by the communication control unit 20. If the determination result is NO, the operation of the authentication device 5 proceeds to step S21. If the determination result is YES, the operation of the authentication device 5 proceeds to step S27.
　ステップＳ２７において、認証部２３は、認証信号を出力する。その後、認証装置５の動作は、ステップＳ２１に進む。 In step S27, the authentication unit 23 outputs an authentication signal. After that, the operation of the authentication device 5 proceeds to step S21.
　図５の右側において、認証アプリケーションによるスマートデバイス４の動作が示される。 On the right side of FIG. 5, the operation of the smart device 4 by the authentication application is shown.
　ステップＳ３１において、受信部１２は、トリガー信号を受信する。その後、スマートデバイス４の動作は、ステップＳ３２に進む。 In step S31, the receiver 12 receives the trigger signal. Then, the operation of the smart device 4 proceeds to step S32.
　ステップＳ３２において、通信制御部１４は、磁気センサー１３が検出する変動磁界の強さが閾値以上であるかを判定する。判定結果がＮＯである場合に、スマートデバイス４の動作は、再びステップＳ３２に進む。判定結果がＹＥＳである場合に、スマートデバイス４の動作は、ステップＳ３３に進む。 In step S32, the communication control unit 14 determines whether or not the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is equal to or more than a threshold value. If the determination result is NO, the operation of the smart device 4 proceeds to step S32 again. If the determination result is YES, the operation of the smart device 4 proceeds to step S33.
　ステップＳ３３において、通信制御部１４は、送信部１１に照合情報の送信を指示する。その後、スマートデバイス４の動作は、ステップＳ３４に進む。 In step S33, the communication control unit 14 instructs the transmission unit 11 to transmit the verification information. After that, the operation of the smart device 4 proceeds to step S34.

　以上に説明したように、実施の形態１に係る認証装置５は、形成部１７と、受信部１９と、認証部２３と、を備える。形成部１７は、照合エリア７の内部全体において強さが予め定められた閾値以上である変動磁界を形成する。照合エリア７は、利用者３が入域可能な空間領域である。照合エリア７は、基準点Ｐおよび基準点Ｐから内部の任意の点までを結ぶ線分を含む。受信部１９は、スマートデバイス４から無線通信により送信される照合情報を受信する。スマートデバイス４は、利用者３に所持される。スマートデバイス４は、磁気センサー１３を搭載する。照合情報は、磁気センサー１３が閾値以上の強さの変動磁界を検出するときに送信される。認証部２３は、受信部１９が照合情報を受信したときに照合情報に基づいて利用者３を認証する。 As described above, the authentication device 5 according to the first embodiment includes the forming unit 17, the receiving unit 19, and the authenticating unit 23. The forming unit 17 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire inside of the matching area 7. The matching area 7 is a spatial area in which the user 3 can enter. The matching area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. The receiving unit 19 receives the matching information transmitted from the smart device 4 by wireless communication. The smart device 4 is owned by the user 3. The smart device 4 has a magnetic sensor 13. The verification information is transmitted when the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than the threshold value. The authentication unit 23 authenticates the user 3 based on the matching information when the receiving unit 19 receives the matching information.
　また、実施の形態１に係る認証システム１は、スマートデバイス４と、認証装置５と、を備える。スマートデバイス４は、利用者３に所持される。スマートデバイス４は、磁気センサー１３を搭載する。スマートデバイス４は、磁気センサー１３が予め定められた閾値以上の強さの変動磁界を検出するときに無線通信によって照合情報を送信する。認証装置５は、照合エリア７の内部全体において強さが予め定められた閾値以上である変動磁界を形成する。照合エリア７は、利用者３が入域可能な空間領域である。照合エリア７は、基準点Ｐおよび基準点Ｐから内部の任意の点までを結ぶ線分を含む。認証装置５は、スマートデバイス４から照合情報を受信したときに照合情報に基づいて利用者３を認証する。 Further, the authentication system 1 according to the first embodiment includes a smart device 4 and an authentication device 5. The smart device 4 is owned by the user 3. The smart device 4 has a magnetic sensor 13. The smart device 4 transmits collation information by wireless communication when the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a predetermined threshold value. The authentication device 5 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire inside of the matching area 7. The matching area 7 is a spatial area in which the user 3 can enter. The matching area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. The authentication device 5 authenticates the user 3 based on the matching information when receiving the matching information from the smart device 4.
　また、実施の形態１に係るスマートデバイス４は、磁気センサー１３と、送信部１１と、を備える。磁気センサー１３は、照合エリア７の内部全体において強さが予め定められた閾値以上に形成された変動磁界を検出する。照合エリア７は、利用者３が入域可能な空間領域である。照合エリア７は、基準点Ｐおよび基準点Ｐから内部の任意の点までを結ぶ線分を含む。送信部１１は、磁気センサー１３が閾値以上の強さの変動磁界を検出するときに、認証装置５に照合情報を無線通信によって送信する。認証装置５は、無線通信によって照合情報を受信したときに照合情報に基づいて利用者３を認証する。 Moreover, the smart device 4 according to the first embodiment includes the magnetic sensor 13 and the transmission unit 11. The magnetic sensor 13 detects a fluctuating magnetic field whose strength is formed above a predetermined threshold value in the entire inside of the matching area 7. The matching area 7 is a spatial area in which the user 3 can enter. The matching area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. When the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a threshold, the transmitter 11 transmits collation information to the authentication device 5 by wireless communication. The authentication device 5 authenticates the user 3 based on the matching information when receiving the matching information by wireless communication.
　磁気センサー１３は、照合エリア７の内部全体において、閾値以上の強さの変動磁界を検出する。磁気センサー１３が当該磁界を検出するときに、認証装置５は、照合情報に基づいて利用者３を認証する。すなわち、形成部１７が形成する変動磁界によって、照合エリア７の内部全体がスマートデバイス４を所持している利用者３の認証が安定して行われる領域として設定される。 The magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a threshold value in the entire inside of the matching area 7. When the magnetic sensor 13 detects the magnetic field, the authentication device 5 authenticates the user 3 based on the collation information. That is, due to the fluctuating magnetic field formed by the forming unit 17, the entire inside of the verification area 7 is set as an area in which the authentication of the user 3 having the smart device 4 is stably performed.
　長波などの波長の長い電磁波は、マルチパスによる影響を受けにくい。一方、長波などを用いた無線通信は、長波用のアンテナなどのハードウェアおよび通信プロトコルに対応したソフトウェアなどを必要とする。一方、認証システム１において、スマートデバイス４は、物理的な量としての変動磁界の強さによって照合エリア７に入域したことを検知する。このため、磁気センサー１３を搭載しているスマートデバイス４であれば、認証システム１に適用できる。スマートデバイス４は、例えば電子コンパス用に地磁気を計測するセンサーとして搭載されているセンサーなどを磁気センサー１３として利用できる。当該センサーは、普及品の汎用のスマートデバイス４に広く搭載されている。このため、普及品のスマートデバイス４を用いた認証システム１の構築ができる。 Electromagnetic waves with long wavelengths such as long waves are not easily affected by multipath. On the other hand, wireless communication using long waves requires hardware such as antennas for long waves and software compatible with communication protocols. On the other hand, in the authentication system 1, the smart device 4 detects that the smart device 4 has entered the verification area 7 based on the strength of the varying magnetic field as a physical quantity. Therefore, any smart device 4 equipped with the magnetic sensor 13 can be applied to the authentication system 1. The smart device 4 can use, for example, a sensor mounted as a sensor for measuring geomagnetism for an electronic compass as the magnetic sensor 13. The sensor is widely mounted on a general-purpose smart device 4 that is a popular product. Therefore, the authentication system 1 using the popular smart device 4 can be constructed.
　認証システム１は、利用者３が照合エリア７に入域してから当該利用者３の認証まで、利用者３の操作を必要としない。このため、認証システム１は、スマートデバイス４の歩きながらの操作を誘発しない。これにより、利用者３の安全性が向上する。 The authentication system 1 does not require the operation of the user 3 from the time the user 3 enters the verification area 7 to the authentication of the user 3. Therefore, the authentication system 1 does not induce the operation of the smart device 4 while walking. This improves the safety of the user 3.
　また、形成部１７は、放射部２４を備える。放射部２４は、長波を放射する。形成部１７は、放射部２４が放射する電磁波である長波の磁界成分によって、照合エリア７の内部全体において強さが閾値以上の変動磁界を形成する。 The forming unit 17 also includes a radiating unit 24. The radiating part 24 radiates a long wave. The forming unit 17 forms a fluctuating magnetic field whose strength is equal to or more than a threshold value in the entire inside of the matching area 7 by the magnetic field component of the long wave which is the electromagnetic wave emitted by the emitting unit 24.
　長波などの波長の長い電磁波は、マルチパスによる影響を受けにくい。電磁波は、変動磁界の成分を有する。変動磁界としての長波は、変動磁界の強さの分布に干渉などによる空間的なばらつきが生じにくい。このため、形成部１７は、基準点Ｐからの距離に応じて減衰する変動磁界を形成できる。これにより、形成部１７は、照合エリア７の内部全体において閾値以上の強さの変動磁界を形成できる。なお、放射部２４は、長波より波長の長い電磁波を放射してもよい。 Electromagnetic waves with long wavelengths such as long waves are not easily affected by multipath. Electromagnetic waves have a varying magnetic field component. The long wave as the fluctuating magnetic field is unlikely to cause spatial variation in the strength distribution of the fluctuating magnetic field due to interference or the like. Therefore, the forming unit 17 can form a fluctuating magnetic field that attenuates according to the distance from the reference point P. As a result, the forming unit 17 can form a fluctuating magnetic field having a strength equal to or higher than the threshold value in the entire inside of the matching area 7. The radiating section 24 may radiate an electromagnetic wave having a wavelength longer than that of a long wave.
　また、形成部１７は、変調部２５を備える。変調部２５は、放射部２４が放射する電磁波を磁気センサー１３が検出可能な周波数に振幅変調により変調する。形成部１７は、変調部２５によって変調された電磁波の磁界成分によって、照合エリア７の内部全体において強さが閾値以上の変動磁界を形成する。なお、変調部２５は、放射部２４が放射する電磁波の周波数を磁気センサー１３が検出可能な周波数に変換してもよい。このとき、変調部２５は、例えば局部発振器および混合器などを備えてもよい。局部発振器は、周波数変換のための予め定められた周波数の信号を発振する機器である。混合器は、局部発振器の信号と放射部２４が放射する電磁波を表す信号とを混合する機器である。 The forming unit 17 also includes a modulating unit 25. The modulator 25 modulates the electromagnetic wave emitted by the radiator 24 into a frequency that can be detected by the magnetic sensor 13 by amplitude modulation. The forming unit 17 forms a fluctuating magnetic field whose strength is equal to or more than a threshold value in the entire inside of the matching area 7 by the magnetic field component of the electromagnetic wave modulated by the modulating unit 25. The modulator 25 may convert the frequency of the electromagnetic wave emitted by the radiator 24 into a frequency that can be detected by the magnetic sensor 13. At this time, the modulator 25 may include, for example, a local oscillator and a mixer. The local oscillator is a device that oscillates a signal having a predetermined frequency for frequency conversion. The mixer is a device that mixes the signal of the local oscillator and the signal representing the electromagnetic wave radiated by the radiation unit 24.
　これにより、磁界の変動の周波数について安定に検出できる上限をする磁気センサー１３を搭載するスマートデバイス４を用いた認証システム１の構築ができる。 With this, it is possible to construct the authentication system 1 using the smart device 4 equipped with the magnetic sensor 13 that has an upper limit that can stably detect the frequency of the fluctuation of the magnetic field.
　認証装置５は、例えば専用のタグ装置などとの間で、長波による通信を行ってもよい。このとき、形成部１７の放射部２４は、例えば長波による通信を行う長波アンテナであってもよい。通信制御部２０は、時間的に交互に、長波による通信および長波の放射による変動磁界の形成を当該長波アンテナにさせてもよい。 The authentication device 5 may perform long-wave communication with, for example, a dedicated tag device. At this time, the radiation unit 24 of the forming unit 17 may be, for example, a long-wave antenna that performs long-wave communication. The communication control unit 20 may cause the long-wave antenna to alternately perform communication by long waves and form a fluctuating magnetic field by radiation of long waves.
　また、形成部１７は、照合エリア７の内部全体において強さが閾値以上の変動磁界を発生させる電磁石を備えてもよい。あるいは、形成部１７は、照合エリア７の内部全体において強さが前記閾値以上の変動磁界を発生させる回転磁石を備えてもよい。形成部１７は、放射部２４とともに電磁石または回転磁石を備えてもよい。形成部１７は、放射部２４に替えて電磁石または回転磁石を備えてもよい。 Further, the forming unit 17 may include an electromagnet that generates a fluctuating magnetic field whose strength is equal to or higher than a threshold value in the entire inside of the matching area 7. Alternatively, the forming unit 17 may include a rotating magnet that generates a fluctuating magnetic field whose strength is equal to or higher than the threshold value in the entire inside of the matching area 7. The forming unit 17 may include an electromagnet or a rotating magnet together with the radiating unit 24. The forming unit 17 may include an electromagnet or a rotating magnet instead of the radiating unit 24.
　これにより、形成部１７は、磁気センサー１３が検出可能な周波数で変動する変動磁界を直接的に形成できる。 With this, the forming unit 17 can directly form a fluctuating magnetic field that fluctuates at a frequency that can be detected by the magnetic sensor 13.
　また、実施の形態１に係る入退室管理システムは、スマートデバイス４と、認証装置５と、電気錠６と、を備える。スマートデバイス４は、利用者３に所持される。スマートデバイス４は、磁気センサー１３を搭載する。スマートデバイス４は、磁気センサー１３が予め定められた閾値以上の強さの変動磁界を検出するときに無線通信によって照合情報を送信する。認証装置５は、照合エリア７の内部全体において強さが予め定められた閾値以上である変動磁界を形成する。照合エリア７は、利用者３が入域可能な空間領域である。照合エリア７は、基準点Ｐおよび基準点Ｐから内部の任意の点までを結ぶ線分を含む。認証装置５は、スマートデバイス４から照合情報を受信したときに照合情報に基づいて利用者３を認証する。認証装置５が利用者３を認証したときに、電気錠６は、扉２の施錠または解錠を行う。 Further, the room entrance / exit management system according to the first embodiment includes a smart device 4, an authentication device 5, and an electric lock 6. The smart device 4 is owned by the user 3. The smart device 4 has a magnetic sensor 13. The smart device 4 transmits collation information by wireless communication when the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a predetermined threshold value. The authentication device 5 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire inside of the matching area 7. The matching area 7 is a spatial area in which the user 3 can enter. The matching area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. The authentication device 5 authenticates the user 3 based on the matching information when receiving the matching information from the smart device 4. When the authentication device 5 authenticates the user 3, the electric lock 6 locks or unlocks the door 2.
　認証装置５は、利用者３が照合エリア７の基準点Ｐから遠方にいるときに、当該利用者３を認証しない。このため、電気錠６は、遠くの利用者３を認証することなどによる不要な解錠を行わない。これにより、建築物のセキュリティ性が高まる。また、認証装置５は、利用者３が照合エリア７の内部に入域したときに当該利用者３を認証する。このため、電気錠６の解錠の遅れが防がれる。これにより、利用者３が扉２の前で解錠を待って立ち止まることなどが防がれる。したがって、利用者３の利便性が高まる。 The authentication device 5 does not authenticate the user 3 when the user 3 is far from the reference point P in the matching area 7. Therefore, the electric lock 6 does not perform unnecessary unlocking by authenticating the distant user 3. This increases the security of the building. Further, the authentication device 5 authenticates the user 3 when the user 3 enters the collation area 7. Therefore, delay in unlocking the electric lock 6 can be prevented. This prevents the user 3 from standing in front of the door 2 waiting for unlocking and stopping. Therefore, the convenience of the user 3 is enhanced.
　また、実施の形態１に係るエレベーター配車管理システムは、スマートデバイス４と、認証装置５と、エレベーター制御盤２８と、を備える。スマートデバイス４は、利用者３に所持される。スマートデバイス４は、磁気センサー１３を搭載する。スマートデバイス４は、磁気センサー１３が予め定められた閾値以上の強さの変動磁界を検出するときに無線通信によって照合情報を送信する。認証装置５は、照合エリア７の内部全体において強さが予め定められた閾値以上である変動磁界を形成する。照合エリア７は、利用者３が入域可能な空間領域である。照合エリア７は、基準点Ｐおよび基準点Ｐから内部の任意の点までを結ぶ線分を含む。認証装置５は、スマートデバイス４から照合情報を受信したときに照合情報に基づいて利用者３を認証する。認証装置５が利用者３を認証したときに、エレベーター制御盤２８は、エレベーターの呼びを登録する。 Further, the elevator vehicle allocation management system according to the first embodiment includes a smart device 4, an authentication device 5, and an elevator control panel 28. The smart device 4 is owned by the user 3. The smart device 4 has a magnetic sensor 13. The smart device 4 transmits collation information by wireless communication when the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a predetermined threshold value. The authentication device 5 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire inside of the matching area 7. The matching area 7 is a spatial area in which the user 3 can enter. The matching area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. The authentication device 5 authenticates the user 3 based on the matching information when receiving the matching information from the smart device 4. When the authentication device 5 authenticates the user 3, the elevator control panel 28 registers the elevator call.
　認証装置５は、利用者３が照合エリア７の基準点Ｐから遠方にいるときに、当該利用者３を認証しない。このため、エレベーター制御盤２８は、利用者３が乗場に到着するまで不必要に長くかごを乗場に待機させない。これにより、エレベーターの利用の効率が高くなる。認証装置５は、利用者３が照合エリア７の内部に入域したときに当該利用者３を認証する。このため、エレベーターの呼びの登録の遅れが防がれる。これにより、利用者３がエレベーターの乗場においてかごの到着を待つ時間が低減される。したがって、利用者３の利便性が高まる。 The authentication device 5 does not authenticate the user 3 when the user 3 is far from the reference point P in the matching area 7. Therefore, the elevator control panel 28 does not unnecessarily wait the car at the hall until the user 3 arrives at the hall. This increases the efficiency of elevator usage. The authentication device 5 authenticates the user 3 when the user 3 enters the collation area 7. Therefore, delay in registration of elevator calls can be prevented. This reduces the time for the user 3 to wait for the arrival of the car at the elevator hall. Therefore, the convenience of the user 3 is enhanced.
　また、実施の形態１に係る測位システムは、スマートデバイス４と、認証装置５と、校正装置２９と、を備える。スマートデバイス４は、利用者３に所持される。スマートデバイス４は、磁気センサー１３を搭載する。スマートデバイス４は、磁気センサー１３が予め定められた閾値以上の強さの変動磁界を検出するときに無線通信によって照合情報を送信する。認証装置５は、照合エリア７の内部全体において強さが予め定められた閾値以上である変動磁界を形成する。照合エリア７は、利用者３が入域可能な空間領域である。照合エリア７は、基準点Ｐおよび基準点Ｐから内部の任意の点までを結ぶ線分を含む。認証装置５は、スマートデバイス４から照合情報を受信したときに照合情報に基づいて利用者３を認証する。認証装置５が利用者３を認証したときに、校正装置２９は、利用者３の位置情報を認証装置５が設けられる位置によって校正する。 Further, the positioning system according to the first embodiment includes the smart device 4, the authentication device 5, and the calibration device 29. The smart device 4 is owned by the user 3. The smart device 4 has a magnetic sensor 13. The smart device 4 transmits collation information by wireless communication when the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a predetermined threshold value. The authentication device 5 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire inside of the matching area 7. The matching area 7 is a spatial area in which the user 3 can enter. The matching area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. The authentication device 5 authenticates the user 3 based on the matching information when receiving the matching information from the smart device 4. When the authentication device 5 authenticates the user 3, the calibration device 29 calibrates the position information of the user 3 by the position where the authentication device 5 is provided.
　認証装置５は、利用者３が照合エリア７の内部に入域したときに当該利用者３を認証する。このため、測位システムは、利用者３の位置を校正装置２９から照合エリア７内の位置に特定できる。ＰＤＲアプリケーションにおいて利用者３の位置情報に誤差が蓄積する場合においても、測位システムは、利用者３の位置情報を校正できる。これにより、測位システムにおいて、利用者３の位置情報の精度が向上する。 The authentication device 5 authenticates the user 3 when the user 3 enters the collation area 7. Therefore, the positioning system can specify the position of the user 3 from the calibration device 29 to the position in the matching area 7. Even when an error is accumulated in the position information of the user 3 in the PDR application, the positioning system can calibrate the position information of the user 3. This improves the accuracy of the position information of the user 3 in the positioning system.
　測位システムが屋内の位置情報を取得する屋内測位システムである場合に、衛星航法システムなどによる位置情報の校正は難しい。この場合の測位システムにおいても、利用者３の位置情報の精度が向上する。 If the positioning system is an indoor positioning system that acquires indoor position information, it is difficult to calibrate the position information using a satellite navigation system. Also in the positioning system in this case, the accuracy of the position information of the user 3 is improved.
　なお、スマートデバイス４の送信部１１および受信部１２は、単一のアンテナを送信アンテナ１５および受信アンテナ１６として共用してもよい。認証装置５の送信部１８および受信部１９は、単一のアンテナを送信アンテナ２６および受信アンテナ２７として共用してもよい。 Note that the transmitting unit 11 and the receiving unit 12 of the smart device 4 may share a single antenna as the transmitting antenna 15 and the receiving antenna 16. The transmitting unit 18 and the receiving unit 19 of the authentication device 5 may share a single antenna as the transmitting antenna 26 and the receiving antenna 27.
　スマートデバイス４および認証装置５は、Ｗｉ－Ｆｉ規格またはその他の規格によって無線通信を行ってもよい。 The smart device 4 and the authentication device 5 may perform wireless communication according to the Wi-Fi standard or other standards.
　認証システム１は、複数の認証装置５を備えてもよい。複数の認証装置５の各々は、電気錠６、エレベーター制御盤２８、校正装置２９およびその他の装置について、認証情報を送信する装置が選択されてもよい。複数の認証装置５の各々は、認証の要件が異なっていてもよい。 The authentication system 1 may include a plurality of authentication devices 5. For each of the plurality of authentication devices 5, a device that transmits authentication information may be selected for the electric lock 6, the elevator control panel 28, the calibration device 29, and other devices. Each of the plurality of authentication devices 5 may have different authentication requirements.

The authentication system 1 may include an authentication server. The authentication server may include an authentication unit 23, an authentication information storage unit 21, and an authentication information processing unit 22.
　続いて、図６を用いて認証システム１のハードウェア構成の例について説明する。
　図６は、実施の形態１に係る認証システムの主要部のハードウェア構成を示す図である。 Subsequently, an example of the hardware configuration of the authentication system 1 will be described with reference to FIG.

The processing circuit may include at least one dedicated hardware 1a together with the processor 1b and the memory 1c, or as a substitute for them.
　処理回路がプロセッサ１ｂとメモリ１ｃとを備える場合、認証システム１の各機能は、ソフトウェア、ファームウェア、またはソフトウェアとファームウェアとの組み合わせで実現される。ソフトウェアおよびファームウェアの少なくとも一方は、プログラムとして記述される。そのプログラムはメモリ１ｃに格納される。プロセッサ１ｂは、メモリ１ｃに記憶されたプログラムを読み出して実行することにより、認証システム１の各機能を実現する。 When the processing circuit includes the processor 1b and the memory 1c, each function of the authentication system 1 is realized by software, firmware, or a combination of software and firmware.

　受信部１２がトリガー信号を受信する場合に、通信制御部１４は、磁気センサー１３が検出する変動磁界の強さに関わらず、送信部１１に照合情報を送信させる。 When the reception unit 12 receives the trigger signal, the communication control unit 14 causes the transmission unit 11 to transmit the matching information regardless of the strength of the fluctuating magnetic field detected by the magnetic sensor 13.
　通信制御部２０は、受信部１９が照合情報の信号を受信したときに、照合情報を取得する。通信制御部２０は、取得した照合情報が例えば暗号化されている場合に、復号化の処理を行う。通信制御部２０は、照合情報からスマートデバイス４の識別情報を抽出する。通信制御部２０は、抽出した識別情報を認証部２３に出力する。 The communication control unit 20 acquires the matching information when the receiving unit 19 receives the signal of the matching information. The communication control unit 20 performs a decryption process when the acquired matching information is encrypted, for example. The communication control unit 20 extracts the identification information of the smart device 4 from the collation information. The communication control unit 20 outputs the extracted identification information to the authentication unit 23.
　認証部２３は、認証情報を認証情報データベースから取得する。認証部２３は、取得した認証情報および識別情報に基づいて、当該識別情報に識別されるスマートデバイス４を所持する利用者３が認証の条件を満たすかを判定する。当該利用者３が認証の条件を満たすと判定する場合に、認証部２３は、入域信号の入力を待機する。当該利用者３が認証の条件を満たすと判定しない場合に、認証部２３は、入域信号の入力を待機せずに、取得した識別情報を破棄する。 The authentication unit 23 acquires the authentication information from the authentication information database. The authentication unit 23 determines, based on the acquired authentication information and identification information, whether the user 3 having the smart device 4 identified by the identification information satisfies the authentication condition. When the user 3 determines that the authentication condition is satisfied, the authentication unit 23 waits for the entry signal.

When the smart device 4 is inside the matching area 7, the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is equal to or higher than the threshold value. At this time, the communication control unit 14 outputs a signal instructing the transmission unit 11 to transmit the arrival signal. The transmitter 11 transmits the incoming signal to the receiver 19.
　通信制御部２０は、受信部１９が入域信号の信号を受信したときに、入域信号を認証部２３に出力する。 The communication control unit 20 outputs the incoming signal to the authentication unit 23 when the receiving unit 19 receives the signal of the incoming signal.
　認証部２３は、入域信号の入力を待機しているときに、入域信号が入力された場合に、利用者３を認証する。認証部２３は、認証信号を電気錠６、エレベーター制御盤２８、および校正装置２９に出力する。 The authentication unit 23 authenticates the user 3 when an incoming signal is input while waiting for the incoming signal.

The forming unit 17 forms a fluctuating magnetic field whose strength is equal to or more than a threshold value in the entire inside of the matching area 7 by the magnetic field component of the electromagnetic wave modulated or converted by the modulating unit 25.
