Subsequently, the function of the authentication system 1 will be described with reference to FIG.

First, the function of registering user information will be described. The user information is registered, for example, by the administrator of the authentication system 1.

The administrator inputs the user information to be registered into the user information processing unit 10. The user information processing unit 10 registers the user information entered in 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 in the user information database. For example, when the user 3 represented by the registered user information is a user 3 who can enter the restricted area, the user information processing unit 10 transmits the authentication information to the authentication information processing unit 22. The authentication information to be transmitted is, for example, a set of the identification information of the smart device 4 possessed by the user 3 and the information for identifying the restricted area.

The authentication information processing unit 22 registers the authentication information acquired from the user information processing unit 10 in the authentication 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.

Next, the authentication function of the user 3 will be described.

The communication control unit 20 outputs a signal instructing the transmission unit 18 to transmit the trigger signal. The transmission unit 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.

The communication control unit 20 outputs a signal instructing the forming unit 17 to form a fluctuating magnetic field. The forming unit 17 forms a fluctuating magnetic field as follows, for example. For example, the forming unit 17 alternately switches between the two forming methods to form a fluctuating magnetic field.

The forming unit 17 forms a fluctuating magnetic field by radiating a long wave from the radiating unit 24 as one of the two forming methods. The frequency of the long wave emitted by the radiating unit 24 is, for example, 100 kHz. The radiating unit 24 radiates a long wave at an output in which the amplitude of the magnetic field component is equal to or greater than the threshold value in the entire inside of the collation area 7.

The forming unit 17 forms a fluctuating magnetic field by modulating the modulation unit 25 with a long wave radiated by the radiating unit 24 as the other of the two forming methods. The modulation unit 25 modulates the long wave emitted by the radiation unit 24 by, for example, amplitude modulation. When a plurality of types of magnetic sensors 13 are assumed as the magnetic sensors 13 mounted on the smart device 4, the modulation unit 25 makes a long wave at a frequency lower than the lowest frequency among the upper limit frequencies of the assumed magnetic sensors 13. To modulate. The modulation unit 25 modulates a long wave to a frequency of, for example, 10 Hz or less.

The smart device 4 operates for the authentication of the authentication system 1 by the installed authentication application.

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 greater than the threshold value. The communication control unit 14 separates, for example, the magnetic field detected by the magnetic sensor 13 into a time-steady component and a time-varying component. The communication control unit 14 determines that the stationary component is due to the geomagnetism. The communication control unit 14 determines that the fluctuating component is due to the fluctuating magnetic field. The communication control unit 14 determines whether the strength of the fluctuating magnetic field is equal to or greater than the threshold value based on, for example, the magnitude of the amplitude of the fluctuating magnetic field.

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 collation area 7, the strength of the fluctuating magnetic field detected by the magnetic sensor 13 becomes less than the threshold value.

On the other hand, when the smart device 4 is inside the collation area 7, the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is equal to or greater than the threshold value. At this time, the communication control unit 14 outputs a signal instructing the transmission unit 11 to transmit the collation information. The transmitting unit 11 establishes a connection with the receiving unit 19 according to the BLE standard. At this time, the transmitting unit 11 and the receiving 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, for example, in the BLE standard, communication with a security level that does not require a pairing authentication operation. After that, the transmitting unit 11 transmits the collation information to the receiving unit 19.

The communication control unit 20 acquires the collation information when the receiving unit 19 receives the radio signal representing the collation information. The communication control unit 20 performs a decryption process when the acquired collation 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.

The authentication unit 23 acquires the authentication information from the authentication information database. Based on the acquired authentication information and identification information, the authentication unit 23 determines whether the user 3 who possesses 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.

The electric lock 6 unlocks the door 2 when the authentication signal is input. The user 3 can enter the restricted area through the door 2. The electric lock 6 locks the door 2 when, for example, a predetermined time has elapsed after unlocking the door 2. Alternatively, the electric lock 6 may lock the unlocked door 2 when the authentication signal is input.

The elevator control panel 28 registers the elevator call when the authentication signal is input. The call is registered, for example, as a landing call from the floor where the authentication device 5 is installed. The elevator control panel 28 drives the elevator car to the floor where the authentication device 5 is provided according to the registered call.

When the authentication signal is input, the calibration device 29 calibrates the position information of the authenticated user 3 according to the position of the authentication device 5. The calibration device 29 calibrates the position information of the user 3 to, for example, a position inside the collation area 7. The calibration device 29 transmits the position information after calibration 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.

Subsequently, an example of modulation by the modulation unit 25 will be described with reference to FIG.
FIG. 3 is a diagram showing an example of modulation in the authentication system according to the first embodiment.

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 modulation unit 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 illustration purposes.

The carrier wave is a long wave emitted by the radiation unit 24. The modulation unit 25 changes the output of the long wave radiated by the radiation unit 24 in two stages of strength and weakness. The modulation unit 25 causes the radiation unit 24 to output a long wave with a strong output for 65 ms. After that, the modulation unit 25 causes the radiation unit 24 to output a long wave with a weak output for 85 ms. The modulation unit 25 repeats this in 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 unit 24 is a 6.6 Hz square wave.

Subsequently, an example of the operation of the authentication system 1 will be described with reference to FIGS. 4 and 5.

In step S23, the forming unit 17 forms a fluctuating magnetic field. After that, the operation of the authentication device 5 proceeds to step S24. The forming unit 17 may continue to form the fluctuating magnetic field until, for example, the communication control unit 20 instructs to end the formation of the fluctuating magnetic field.

In step S24, the communication control unit 20 determines whether the receiving unit 19 has received the collation information. 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.

In step S32, the communication control unit 14 determines whether the strength of the fluctuating magnetic field detected by the magnetic sensor 13 is equal to or greater than the 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.

In step S33, the communication control unit 14 instructs the transmission unit 11 to transmit the collation information. After that, the operation of the smart device 4 proceeds to step S34.

In step S34, the transmission unit 11 transmits the collation information. After that, the operation of the smart device 4 proceeds to step S31.

As described above, the authentication device 5 according to the first embodiment includes a forming unit 17, a receiving unit 19, and an authentication 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 collation area 7. The collation area 7 is a spatial area in which the user 3 can enter. The collation 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 collation information transmitted by wireless communication from the smart device 4. The smart device 4 is possessed by the user 3. The smart device 4 is equipped with a magnetic sensor 13. The collation information is transmitted when the magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a threshold value. When the receiving unit 19 receives the collation information, the authentication unit 23 authenticates the user 3 based on the collation information.

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 possessed by the user 3. The smart device 4 is equipped with 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 collation area 7. The collation area 7 is a spatial area in which the user 3 can enter. The collation area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. When the authentication device 5 receives the verification information from the smart device 4, the authentication device 5 authenticates the user 3 based on the verification information.

Further, the smart device 4 according to the first embodiment includes a magnetic sensor 13 and a 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 collation area 7. The collation area 7 is a spatial area in which the user 3 can enter. The collation 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 the threshold value, the transmission unit 11 transmits the verification information to the authentication device 5 by wireless communication. The authentication device 5 authenticates the user 3 based on the collation information when the collation information is received by wireless communication.

The magnetic sensor 13 detects a fluctuating magnetic field having a strength equal to or higher than a threshold value in the entire collation 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 collation area 7 is set as an area where the authentication of the user 3 who possesses the smart device 4 is stably performed.

Electromagnetic waves with long wavelengths such as long waves are not easily affected by multipath. On the other hand, wireless communication using a long wave or the like requires hardware such as an antenna for a long wave and software corresponding to a communication protocol. On the other hand, in the authentication system 1, the smart device 4 detects that it has entered the collation area 7 by the strength of the fluctuating 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. As the smart device 4, for example, a sensor mounted as a sensor for measuring the geomagnetism for an electronic compass can be used as the magnetic sensor 13. The sensor is widely installed in a popular general-purpose smart device 4. Therefore, the authentication system 1 can be constructed using the popular smart device 4.

The authentication system 1 does not require the operation of the user 3 from the time when the user 3 enters the verification area 7 to the authentication of the user 3. Therefore, the authentication system 1 does not induce the smart device 4 to operate while walking. As a result, the safety of the user 3 is improved.

Further, the forming portion 17 includes a radiating portion 24. The radiating unit 24 radiates a long wave. The forming unit 17 forms a fluctuating magnetic field having a strength equal to or higher than a threshold value in the entire inside of the collation area 7 by a long-wave magnetic field component which is an electromagnetic wave emitted by the radiating unit 24.

Electromagnetic waves with long wavelengths such as long waves are not easily affected by multipath. Electromagnetic waves have a component of a fluctuating magnetic field. A long wave as a fluctuating magnetic field is less likely to cause spatial variation due to interference or the like in the distribution of the strength of the fluctuating magnetic field. Therefore, the forming portion 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 collation area 7. The radiating unit 24 may radiate an electromagnetic wave having a wavelength longer than that of a long wave.

Further, the forming unit 17 includes a modulation unit 25. The modulation unit 25 modulates the electromagnetic wave emitted by the radiation unit 24 to a frequency that can be detected by the magnetic sensor 13 by amplitude modulation. The forming unit 17 forms a fluctuating magnetic field having a strength equal to or higher than a threshold value in the entire inside of the collation area 7 by the magnetic field component of the electromagnetic wave modulated by the modulation unit 25. The modulation unit 25 may convert the frequency of the electromagnetic wave radiated by the radiation unit 24 into a frequency that can be detected by the magnetic sensor 13. At this time, the modulation unit 25 may include, for example, a local oscillator and a mixer. A local oscillator is a device that oscillates a signal of 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 emitted by the radiation unit 24.

As a result, it is possible to construct an authentication system 1 using a smart device 4 equipped with a magnetic sensor 13 that limits the frequency of fluctuations in the magnetic field so that it can be stably detected.

The authentication device 5 may perform long-wave communication with, for example, a dedicated tag device. At this time, the radiating portion 24 of the forming portion 17 may be, for example, a long wave antenna that communicates by a long wave. The communication control unit 20 may cause the long wave antenna to perform communication by a long wave and formation of a fluctuating magnetic field by radiation of a long wave alternately in time.

Further, the forming portion 17 may include an electromagnet that generates a fluctuating magnetic field having a strength equal to or higher than a threshold value in the entire inside of the collation area 7. Alternatively, the forming unit 17 may include a rotating magnet that generates a fluctuating magnetic field whose strength is equal to or greater than the threshold value in the entire inside of the collation area 7. The forming portion 17 may include an electromagnet or a rotating magnet together with the radiating portion 24. The forming portion 17 may include an electromagnet or a rotating magnet in place of the radiating portion 24.

As a result, 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.

Further, the entry / 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 possessed by the user 3. The smart device 4 is equipped with 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 collation area 7. The collation area 7 is a spatial area in which the user 3 can enter. The collation area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. When the authentication device 5 receives the verification information from the smart device 4, the authentication device 5 authenticates the user 3 based on the verification information. When the authentication device 5 authenticates the user 3, the electric lock 6 locks or unlocks the door 2.

The authentication device 5 does not authenticate the user 3 when the user 3 is far from the reference point P in the verification area 7. Therefore, the electric lock 6 does not perform unnecessary unlocking by authenticating the distant user 3. This enhances the security of the building. Further, the authentication device 5 authenticates the user 3 when the user 3 enters the inside of the verification area 7. Therefore, the delay in unlocking the electric lock 6 can be prevented. As a result, it is possible to prevent the user 3 from stopping in front of the door 2 waiting for unlocking. Therefore, the convenience of the user 3 is enhanced.

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 possessed by the user 3. The smart device 4 is equipped with a magnetic sensor 13.

The authentication device 5 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire collation area 7. The collation area 7 is a spatial area in which the user 3 can enter. The collation area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. When the authentication device 5 receives the verification information from the smart device 4, the authentication device 5 authenticates the user 3 based on the verification information. When the authentication device 5 authenticates the user 3, the elevator control panel 28 registers the elevator call.

The authentication device 5 does not authenticate the user 3 when the user 3 is far from the reference point P in the verification area 7. Therefore, the elevator control panel 28 does not allow the car to wait at the landing for an unnecessarily long time until the user 3 arrives at the landing. This increases the efficiency of using the elevator. The authentication device 5 authenticates the user 3 when the user 3 enters the collation area 7. Therefore, the delay in the registration of the elevator call can be prevented. As a result, the time for the user 3 to wait for the car to arrive at the elevator landing is reduced. Therefore, the convenience of the user 3 is enhanced.

Further, the positioning system according to the first embodiment includes a smart device 4, an authentication device 5, and a calibration device 29. The smart device 4 is possessed by the user 3. The smart device 4 is equipped with a magnetic sensor 13.

The authentication device 5 forms a fluctuating magnetic field whose strength is equal to or higher than a predetermined threshold value in the entire collation area 7. The collation area 7 is a spatial area in which the user 3 can enter. The collation area 7 includes a reference point P and a line segment connecting the reference point P to an arbitrary point inside. When the authentication device 5 receives the verification information from the smart device 4, the authentication device 5 authenticates the user 3 based on the verification information. When the authentication device 5 authenticates the user 3, the calibration device 29 calibrates the position information of the user 3 according to the position where the authentication device 5 is provided.

The authentication device 5 authenticates the user 3 when the user 3 enters the collation area 7. Therefore, the positioning system can identify the position of the user 3 from the calibration device 29 to the position in the collation 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. As a result, the accuracy of the position information of the user 3 is improved in the positioning system.

When the positioning system is an indoor positioning system that acquires indoor position information, it is difficult to calibrate the position information by a satellite navigation system or the like. Also in the positioning system in this case, the accuracy of the position information of the user 3 is improved.

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.

The authentication system 1 may include a plurality of authentication devices 5. For each of the plurality of authentication devices 5, a device for transmitting authentication information may be selected for the electric lock 6, the elevator control panel 28, the calibration device 29, and other devices.

The forming unit 17 forms a fluctuating magnetic field by modulating or converting the electromagnetic wave radiated by the transmitting antenna 26 into the modulation unit 25. The modulation unit 25 modulates the electromagnetic wave emitted by the radiation unit 24 by, for example, amplitude modulation. Alternatively, the modulation unit 25 converts the frequency of the electromagnetic wave emitted by the radiation unit 24. When a plurality of types of magnetic sensors 13 are assumed as the magnetic sensors 13 mounted on the smart device 4, the modulation unit 25 makes a long wave at a frequency lower than the lowest frequency among the upper limit frequencies of the assumed magnetic sensors 13. To modulate or convert. The modulation unit 25 modulates or converts a long wave to a frequency of, for example, 10 Hz or less.

As described above, the authentication device 5 according to the third embodiment includes a transmission unit 11. The transmission unit 11 transmits a wireless communication signal to the smart device 4 by radiating electromagnetic waves. The signal transmitted by the transmission unit 11 is, for example, a trigger signal. The forming unit 17 of the authentication device 5 includes a modulation unit 25. The modulation unit 25 modulates or converts the electromagnetic wave radiated by the transmission unit 11 to a frequency that can be detected by the magnetic sensor 13. The forming unit 17 forms a fluctuating magnetic field having a strength equal to or higher than a threshold value in the entire inside of the collation area 7 by the magnetic field component of the electromagnetic wave modulated or converted by the modulation unit 25.

As a result, the authentication device 5 does not require hardware that emits electromagnetic waves in addition to the transmission unit 18. Therefore, the hardware configuration of the authentication device 5 is simplified.
