<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of an electric lock control device 1 according to the first embodiment. The electric lock control device 1 is an information processing device that controls an electric lock wirelessly connected to a wireless relay device (not shown). Further, the electric lock control device 1 is connected to the wireless relay device via a network (not shown). Therefore, the electric lock control device 1 controls the locking and unlocking of the electric lock via the wireless relay device. Further, the electric lock control device 1 is connected to a user terminal (not shown) via a network. The user terminal is an information terminal possessed by a user who desires to unlock the electric lock. The user terminal can be wirelessly connected to the wireless relay device.

The electric lock control device 1 includes a storage unit 11, a terminal communication unit 12, an acquisition unit 13, and an unlocking unit 14. The storage unit 11 is a storage device that stores the electric lock ID 111, the relay device ID 112, and the user ID 113 in association with each other. The electric lock ID 111 is identification information of the electric lock connected to the wireless relay device. The relay device ID 112 is identification information of the wireless relay device. The user ID 113 is identification information of a user who is permitted to unlock the electric lock corresponding to the electric lock ID 111.

The terminal communication unit 12 acquires the relay device ID of the wireless relay device to which the user terminal is connected from the predetermined user terminal. Then, the terminal communication unit 12 refers to the storage unit 11 and gives a predetermined notification according to the acquired relay device ID to the user terminal. "According to the relay device ID" may be, for example, a case where the acquired relay device ID and the relay device ID 112 stored in the storage unit 11 match. Further, the "predetermined notification" may be, for example, permission to acquire the biometric information of the user on the user terminal.

The acquisition unit 13 acquires the biometric authentication result based on the biometric information of the user acquired by the user terminal based on the notification. That is, when the user terminal receives the notification from the terminal communication unit 12, the user terminal acquires the biometric information from the user based on the notification. Here, the user terminal may control biometric authentication based on biometric information and transmit the biometric authentication result to the electric lock control device 1. Alternatively, the user terminal may transmit biometric information to the electric lock control device 1, and the electric lock control device 1 may control biometric authentication based on the biometric information and acquire the biometric authentication result. At this time, the electric lock control device 1 may transmit biometric information to a predetermined authentication server (not shown) and acquire the biometric authentication result from the authentication server.

When the user ID specified when the biometric authentication result indicates success and the user ID associated with the relay device ID acquired by the terminal communication unit 12, the unlocking unit 14 matches the relay device ID and the relay device ID. The electric lock ID associated with the set of user IDs is specified. Then, the unlocking unit 14 instructs the electric lock corresponding to the specified electric lock ID to be unlocked.

FIG. 2 is a flowchart showing the flow of the electric lock control method according to the first embodiment. As a premise, it is assumed that the predetermined electric lock and the wireless relay device are already wirelessly connected. Further, it is assumed that the user terminal is also wirelessly connected to the wireless relay device.

First, the terminal communication unit 12 acquires the relay device ID of the wireless relay device to which the user terminal is connected from the user terminal (S11). Next, the terminal communication unit 12 refers to the storage unit 11 and gives a predetermined notification according to the acquired relay device ID to the user terminal (S12). Then, the acquisition unit 13 acquires the biometric authentication result based on the biometric information of the user acquired by the user terminal based on the notification (S13). Here, it is assumed that the biometric authentication result indicates success.

Then, the unlocking unit 14 determines whether or not the user ID specified when the biometric authentication result indicates success and the user ID associated with the relay device ID acquired in step S11 match. S14). When it is determined that the user IDs match, the unlocking unit 14 refers to the storage unit 11 and identifies the electric lock ID associated with the set of the relay device ID and the user ID (S15). Then, the unlocking unit 14 instructs the electric lock corresponding to the specified electric lock ID to be unlocked (S16). That is, the unlocking unit 14 instructs the electric lock to be unlocked via the wireless relay device. On the other hand, if it is determined in step S14 that the user IDs do not match, the process ends.

As described above, in the present embodiment, the correspondence between the electric lock ID 111, the relay device ID 112, and the user ID 113 is registered in advance in the storage unit 11. Here, the relay device ID 112 is identification information of the wireless relay device to which the electric lock corresponding to the electric lock ID 111 is wirelessly connected. In this state, when a predetermined user terminal is wirelessly connected to the wireless relay device, the relay device ID is acquired. Therefore, when the electric lock control device 1 acquires the relay device ID from the user terminal and collates with the relay device ID 112 in the storage unit 11 and matches, the user terminal is connected to the same wireless relay device as the electric lock. That is, it can be confirmed that it is located near the electric lock. Then, on that condition, the user terminal is instructed to perform biometric authentication. By succeeding in biometric authentication of the user who possesses the user terminal, the electric lock control device 1 can acquire the user ID of the user. The electric lock control device 1 is a person who is authorized to unlock the electric lock by the user who owns the user terminal by matching the acquired user ID with the user ID 113 stored in the storage unit 11. Can be confirmed. Therefore, the electric lock control device 1 instructs the electric lock to unlock. As described above, in this embodiment, high security can be ensured. Further, the electric lock may have a wireless connection function with a wireless relay device and an unlocking processing function according to an unlocking instruction. That is, since the electric lock does not require a communication unit having a short-range wireless communication means as in Patent Document 1, the introduction burden can be reduced.

The electric lock control device 1 includes a processor, a memory, and a storage device as a configuration (not shown). Further, the storage device (or the storage unit 11) stores a computer program in which the processing of the electric lock control method according to the present embodiment is implemented. Then, the processor reads the computer program from the storage device into the memory and executes the computer program. As a result, the processor realizes the functions of the terminal communication unit 12, the acquisition unit 13, and the unlocking unit 14.

Alternatively, the terminal communication unit 12, the acquisition unit 13, and the unlocking unit 14 may each be realized by dedicated hardware. Further, a part or all of each component of each device may be realized by a general-purpose or dedicated circuitry, a processor, or a combination thereof. These may be composed of a single chip or may be composed of a plurality of chips connected via a bus. A part or all of each component of each device may be realized by the combination of the circuit or the like and the program described above. Further, as the processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (Field-Programmable Gate Array), a quantum processor (quantum computer control chip) and the like can be used.

Further, when a part or all of each component of the electric lock control device 1 is realized by a plurality of information processing devices and circuits, the plurality of information processing devices and circuits may be centrally arranged. , May be distributed. For example, the information processing device, the circuit, and the like may be realized as a form in which each is connected via a communication network, such as a client-server system and a cloud computing system. Further, the function of the electric lock control device 1 may be provided in the SAAS (Software as a Service) format.

Further, the server is connected to the user terminal 2 via a network. The user terminal 2 is an information terminal possessed by a user who desires to unlock the electric lock. The user terminal 2 can be wirelessly connected to the wireless relay device.

The user terminal 2 includes an acquisition unit 21, a transmission unit 22, a reception unit 23, a determination unit 24, an authentication control unit 25, and a request unit 26. The acquisition unit 21 acquires the relay device ID of the wireless relay device to which the user terminal 2 is wirelessly connected.

The transmission unit 22 transmits the acquired relay device ID to the server including the database. The receiving unit 23 receives a predetermined notification according to the transmitted relay device ID from the server based on the database. “According to the relay device ID” and “predetermined notification” are the same as those in the first embodiment described above.

The determination unit 24 determines whether or not to perform biometric authentication in response to the notification. When it is determined that the biometric authentication is performed, the authentication control unit 25 acquires the biometric authentication result based on the biometric information acquired from the user. Here, the user terminal 2 may acquire the biometric authentication result by controlling the biometric authentication based on the biometric information. Alternatively, the user terminal 2 may transmit biometric information to a predetermined authentication server (not shown) and acquire the biometric authentication result from the authentication server.

The requesting unit 26 transmits the user ID specified when the biometric authentication result indicates success to the server. That is, the requesting unit 26 requests the unlocking of the electric lock corresponding to the electric lock ID associated with the set of the user ID and the transmitted relay device ID in the database by the transmission.

FIG. 4 is a flowchart showing the flow of the electric lock control method according to the second embodiment. As a premise, it is assumed that the predetermined electric lock and the wireless relay device are already wirelessly connected. Further, it is assumed that the user terminal 2 is also wirelessly connected to the wireless relay device.

First, the acquisition unit 21 acquires the relay device ID of the wirelessly connected wireless relay device (S21). Next, the transmission unit 22 transmits the relay device ID acquired in step S21 to the server including the database (S22). Then, the receiving unit 23 receives a predetermined notification according to the transmitted relay device ID from the server based on the database (S23).

After that, the determination unit 24 determines whether or not to perform biometric authentication in response to the notification (S24). For example, when the "notification" indicates the permission of biometric authentication, the determination unit 24 determines that biometric authentication is performed. When it is determined in step S24 that the biometric authentication is performed, the authentication control unit 25 acquires the biometric authentication result based on the biometric information acquired from the user (S25). Then, the requesting unit 26 transmits the user ID specified when the biometric authentication result indicates success to the server. That is, the requesting unit 26 requests the unlocking of the electric lock corresponding to the electric lock ID associated with the set of the user ID and the transmitted relay device ID in the database by the transmission. S26).

As described above, in the present embodiment, the user terminal 2 transmits the relay device ID of the wireless relay device to which the user terminal 2 is wirelessly connected to the server having the same database (storage unit 11) as in the above-described first embodiment. .. From this, the server can confirm that the user terminal 2 is connected to the same wireless relay device as the electric lock, that is, it is located in the vicinity of the electric lock. In response to this, the user terminal 2 is permitted to perform biometric authentication of the user, and transmits the user ID included in the biometric authentication result to the server. As a result, as in the first embodiment described above, the server is authorized to unlock the electric lock by the user who owns the user terminal 2 by matching the acquired user ID with the user ID stored in the database.

<Embodiment 3>
FIG. 5 is a block diagram showing the overall configuration of the electric lock control system 1000 according to the third embodiment. The electric lock control system 1000 unlocks the electric lock 100 wirelessly connected to the wireless router 300 when the user terminal 200 possessed by the user U1 who is authorized to unlock is within the predetermined range of the electric lock 100. It is an information system. The electric lock control system 1000 includes a door 10, a user terminal 200, a wireless router 300, a management terminal 400, an electric lock control server 500, and an authentication server 600. The wireless router 300, the management terminal 400, the electric lock control server 500, and the authentication server 600 are connected via the network N. The network N is a wired or wireless communication line.

An electric lock 100 is installed on the door 10. The electric lock 100 includes a locking / unlocking control unit 101 and a wireless communication unit 102. The lock / unlock control unit 101 is a device that controls the lock / unlock of the key of the door 10. The locking / unlocking control unit 101 locks and unlocks according to a control signal from the outside. The wireless communication unit 102 is a device that wirelessly connects to the wireless router 300 and performs wireless communication. That is, the wireless communication unit 102 receives the control signal from the electric lock control server 500 via the network N and the wireless router 300, and outputs the control signal to the lock / unlock control unit 101. Then, the lock / unlock control unit 101 locks and unlocks the door 10 in response to a control signal from the wireless communication unit 102.

The user terminal 200 is an example of the user terminal 2 described above, and is an information terminal possessed by the user U1. The user terminal 200 is, for example, a portable information terminal such as a smartphone or a tablet terminal. Here, the user terminal 200 shows a state of being wirelessly connected to the wireless router 300. The internal configuration of the user terminal 200 will be described later. Further, the user terminal 200 may directly perform wireless communication with the network N using a mobile phone line (without going through the wireless router 300). Therefore, in the following description, when the user terminal 200 communicates with the electric lock control server 500 or the authentication server 600, it suffices to go through at least the network N. The communication via the network N of the user terminal 200 includes both the case of passing through the wireless router 300 and the case of passing through the mobile phone line.

The wireless router 300 is an example of the above-mentioned wireless relay device. The wireless router 300 is also called a wireless LAN (Local Area Network) access point. The wireless router 300 is connected to the network N, and can also be wirelessly connected to the electric lock 100 and the user terminal 200. Since the wireless router 300 can be realized by using a known technique, detailed description thereof will be omitted.

In the following description, biometric authentication is referred to as face authentication and biometric information is referred to as facial feature information, but other techniques using captured images can be applied to biometric authentication and biometric information. For example, as the biological information, data (feature amount) calculated from physical characteristics peculiar to an individual such as fingerprints, voice prints, veins, retinas, and iris patterns (patterns) of the pupil may be used.

The authentication server 600 is an information processing device that stores facial feature information of a plurality of persons. Further, the authentication server 600 collates the face image or face feature information included in the request with the face feature information of each user in response to the face recognition request received from the outside, and requests the collation result (authentication result). Reply to the original. If the face authentication is successful, the authentication result includes the user ID for which the face authentication is successful. On the other hand, if the face authentication fails, the user ID becomes null as the authentication result.

FIG. 6 is a block diagram showing the configuration of the authentication server 600 according to the third embodiment. The authentication server 600 includes a face information DB (DataBase) 610, a face detection unit 620, a feature point extraction unit 630, a registration unit 640, and an authentication unit 650. The face information DB 610 stores the user ID 611 and the face feature information 612 of the user ID in association with each other. Instead of the face feature information 612, the face image itself may be stored. The face feature information 612 is a set of feature points extracted from the face image. The authentication server 600 may delete the face feature information 612 in the face feature DB 610 in response to a request from the key manager U2 who is a registered user of the face feature information 612. Alternatively, the authentication server 600 may be deleted after a certain period of time has elapsed from the registration of the face feature information 612.

The face detection unit 620 detects a face area included in the registered image for registering face information, and outputs the face region to the feature point extraction unit 630. The feature point extraction unit 630 extracts feature points from the face region detected by the face detection unit 620, and outputs face feature information to the registration unit 640. Further, the feature point extraction unit 630 extracts the feature points included in the face image received from the user terminal 200 or the management terminal 400, and outputs the face feature information to the authentication unit 650.

The registration unit 640 newly issues the user ID 611 when registering the facial feature information. The registration unit 640 registers the issued user ID 611 and the face feature information 612 extracted from the registered image in the face information DB 610 in association with each other. The authentication unit 650 performs face authentication using the face feature information 612. Specifically, the authentication unit 650 collates the face feature information extracted from the face image with the face feature information 612 in the face information DB 610. The authentication unit 650 returns the presence / absence of matching of the face feature information to the requester for face authentication. The presence or absence of matching of facial feature information corresponds to the success or failure of authentication. In addition, the fact that the facial feature information matches (with matching) means that the degree of matching is equal to or higher than a predetermined value.

FIG. 7 is a block diagram showing the configuration of the electric lock control server 500 according to the third embodiment. The electric lock control server 500 is an example of the above-mentioned electric lock control device 1. The electric lock control server 500 includes a storage unit 510, a memory 520, an IF (InterFace) unit 530, and a control unit 540. The storage unit 510 is a storage device such as a hard disk and a flash memory. The storage unit 510 stores the program 511 and the key management information 512. The program 511 is a computer program in which the processing in the electric lock control server 500 of the electric lock control method according to the third embodiment is implemented.

The key management information 512 is information in which the SSID (Service Set Identifier) 5121, the terminal ID 5122, the user ID 5123, and the electronic lock ID 5124 are associated with each other. SSID5121 is an example of the above-mentioned relay device ID112. Here, the SSID 5121 is the identification information of the wireless router 300. The terminal ID 5122 is identification information of the user terminal 200. User ID 5123 is an example of the above-mentioned user ID 113. Here, it is assumed that the user ID 5123 is the identification information of the user U1 and is the same as the information registered as the user ID 611 in the face information DB 610 of the authentication server 600. The electronic lock ID 5124 is an example of the electric lock ID 111 described above. Here, the electronic lock ID 5124 is the identification information of the electric lock 100. The key management information 512 may include a plurality of sets of SSID 5121, terminal ID 5122, user ID 5123, and electronic lock ID 5124. Further, each set may have a partial overlap of SSID5121 and the like.

The memory 520 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information when the control unit 540 operates. The IF unit 530 is a communication interface with the network N.

The control unit 540 is a processor, that is, a control device that controls each configuration of the electric lock control server 500. The control unit 540 reads the program 511 from the storage unit 510 into the memory 520 and executes the program 511. As a result, the control unit 540 realizes the functions of the registration unit 541, the terminal communication unit 542, the acquisition unit 543, and the unlocking unit 544.

The registration unit 541 registers the information received from the management terminal 400 or the like via the network N in the storage unit 510. For example, the registration unit 541 receives the SSID 5121, the terminal ID 5122, the user ID 5123, and the electronic lock ID 5124 by the pre-registration process described later, and stores them in the storage unit 510 as key management information 512 in association with each other.

The terminal communication unit 542 is an example of the terminal communication unit 12 described above. The terminal communication unit 542 performs processing including transmission / reception of data to / from the user terminal 200 via the network N. For example, the terminal communication unit 542 receives the SSID from the user terminal 200, acquires the terminal ID 5122 associated with the SSID 5121 received in the key management information 512, and returns the terminal ID 5122 to the user terminal 200. That is, the terminal communication unit 542 notifies when the SSID 5121 stored in the storage unit 510 and the SSID acquired from the user terminal 200 match. Here, it is assumed that the terminal ID associated with the SSID is transmitted as a notification. Further, the verification of the SSID in the terminal communication unit 542 can be said to be one of the determination processes for determining whether the user terminal 200 is qualified to unlock the electric lock. Therefore, the notification can also be called a permission signal in a broad sense for the user terminal 200.

Further, the terminal communication unit 542 transmits the electric lock ID specified by the unlocking unit 544, which will be described later, to the user terminal 200. Specifically, the terminal communication unit 542 transmits an unlock message indicating that the electric lock 100 has been unlocked to the user terminal 200. As a result, the user terminal 200 can be explicitly notified of the doors that can be entered (the electric lock is unlocked).

The acquisition unit 543 is an example of the acquisition unit 13 described above. The acquisition unit 543 acquires information including the face authentication result from the user terminal 200 via the network N. For example, the acquisition unit 543 receives from the user terminal 200 the user ID included in the face recognition result, the SSID of the wireless router 300 to which the user terminal 200 is wirelessly connected, the terminal ID of the user terminal 200, and the like.

The unlocking unit 544 is an example of the unlocking unit 14 described above. The unlocking unit 544 identifies the electronic lock ID 5124 from the key management information 512 based on various IDs acquired by the acquisition unit 543, and instructs the electric lock corresponding to the electronic lock ID 5124 to unlock. That is, the unlocking unit 544 succeeds in collating the terminal ID returned from the electric lock control server 500 in the user terminal 200, the current position information is within the predetermined range of the electric lock 100, and the user U1 succeeds in face authentication. Allow unlocking on condition that you have done so. Specifically, the unlocking unit 544 transmits an unlocking signal to the electric lock 100 via the network N and the wireless router 300.

FIG. 8 is a block diagram showing the configuration of the user terminal 200 according to the third embodiment. The user terminal 200 includes a storage unit 210, a camera 220, a touch panel 230, a position information acquisition unit 240, a memory 250, a wireless communication unit 260, and a control unit 270. The storage unit 210 is a storage device such as a flash memory. The storage unit 210 stores the program 211, the terminal ID 212, and the area information 213. The program 211 is a computer program in which the processing in the user terminal 200 of the electric lock control method according to the third embodiment is implemented.

The terminal ID 212 is identification information of the user terminal 200.
The area information 213 is information indicating the existence position of the user terminal 200 that permits the unlocking of the electric lock 100. The area information 213 is defined by, for example, the latitude / longitude and the radius of the electric lock 100. That is, the area information 213 is information indicating a range (region) of the radius centered on the latitude and longitude of the electric lock 100.

The camera 220 is a photographing device that photographs according to the control of the control unit 270. The touch panel 230 includes a display device (display unit) such as a screen and an input device. The position information acquisition unit 240 acquires the current position information of the user terminal 200 periodically or in response to an instruction from the control unit 270. The position information acquisition unit 240 communicates with, for example, a GPS (Global Positioning System) satellite and acquires GPS information as position information.

The memory 250 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information when the control unit 270 is operated. The wireless communication unit 260 processes the wireless communication with the wireless router 300 after establishing and establishing the wireless connection with the wireless router 300.

The control unit 270 is a processor, that is, a control device that controls each configuration of the user terminal 200. The control unit 270 reads the program 211 from the storage unit 210 into the memory 250, and executes the program 211. As a result, the control unit 270 realizes the functions of the registration unit 271, the server communication unit 272, the determination unit 273, the input / output control unit 274, and the authentication control unit 275.

The registration unit 271 registers the information received from the management terminal 400 or the like via the network N in the storage unit 210. For example, the registration unit 271 receives the area information 213 and stores it in the storage unit 210 by the pre-registration process described later.

The server communication unit 272 is an example of the acquisition unit 21, the transmission unit 22, the reception unit 23, and the request unit 26 described above. That is, the server communication unit 272 acquires the SSID of the wireless router 300 when the user terminal 200 is wirelessly connected to the wireless router 300. Then, the server communication unit 272 transmits the acquired SSID to the electric lock control server 500 via the network N. The server communication unit 272 receives the terminal ID as a predetermined notification according to the SSID transmitted from the electric lock control server 500 via the network N.

Further, when the face authentication is successful, the server communication unit 272 transmits the user ID included in the face authentication result, the acquired SSID, and the terminal ID 212 to the electric lock control server 500 via the network N. That is, the server communication unit 272 requests the electric lock control server 500 to unlock the electric lock 100 by transmitting these.

Further, the server communication unit 272 receives the electric lock ID from the electric lock control server 500 via the network N. Specifically, the server communication unit 272 receives the unlock message from the electric lock control server 500.

The determination unit 273 is an example of the determination unit 24 described above. The determination unit 273 determines whether or not to perform face recognition in response to the notification from the electric lock control server 500. Specifically, when the following conditions 1 and 2 are satisfied, the determination unit 273 determines that face recognition is performed. First, the determination unit 273 collates the terminal ID received from the electric lock control server 500 with the terminal ID 212 stored in the storage unit 210, and determines whether or not they match (condition 1). If the terminal IDs match, condition 1 is satisfied. Further, the determination unit 273 determines whether or not the position information acquired by the position information acquisition unit 240 is within the range of the area information 213 (condition 2). When the position information is within the range of the area information 213, the condition 2 is satisfied. When the determination unit 273 satisfies the conditions 1 and 2, the determination unit 273 notifies the input / output control unit 274 to that effect. Specifically, the determination unit 273 outputs a signal for activating the entrance button to the input / output control unit 274.

The determination unit 273 may determine only one of the condition 1 and the condition 2. That is, the determination unit 273 may determine that face recognition is performed when the acquired position information is included in the range of the area information 213. Alternatively, the determination unit 273 may determine that face authentication is performed when the received terminal ID and the terminal ID 212 stored in the storage unit 210 match.

The input / output control unit 274 controls the camera 220 and the touch panel 230. When the input / output control unit 274 receives a signal for activating the entrance button from the determination unit 273, the input / output control unit 274 activates the "entrance button" displayed on the touch panel 230. That is, the user U1 cannot tap the "entrance button" until the conditions 1 and 2 are satisfied. Then, when the input / output control unit 274 receives the tap of the "entrance button" from the user U1, it controls the camera 220 and takes a picture of the area including the face of the user U1. Then, the input / output control unit 274 notifies the authentication control unit 275 of the captured face image (of the user U1).

The authentication control unit 275 is an example of the above-mentioned authentication control unit 25. The authentication control unit 275 transmits a face authentication request including a face image notified from the input / output control unit 274 to the authentication server 600 via the network N. Then, the authentication control unit 275 receives (acquires) the face authentication result from the authentication server 600 via the network N. The authentication control unit 275 notifies the server communication unit 272 of the face authentication result.

Returning to FIG. 5, the explanation will be continued. The management terminal 400 is an information processing device operated by the key manager U2. The management terminal 400 may be a smartphone, a tablet terminal, a personal computer, or the like. The management terminal 400 performs a pre-registration process described later according to the operation of the key manager U2. Specifically, the management terminal 400 transmits the input-accepted information to the electric lock control server 500 and the authentication server 600 via the network N, and requests registration.

FIG. 9 is a flowchart showing the flow of the pre-registration process according to the third embodiment. Here, a case is shown in which pre-registration is performed to allow the user U1 possessing the user terminal 200 to unlock the electric lock 100.

First, the key manager U2 wirelessly connects the electric lock 100 to the (predesignated) wireless router 300 installed near the door 10 (S31). That is, by the operation of the key manager U2, the electric lock 100 wirelessly connects to the wireless router 300. Specifically, the wireless communication unit 102 of the electric lock 100 and the wireless router 300 establish a wireless connection.

Next, the key manager U2 associates the SSID of the wireless router 300 with the electric lock ID of the electric lock 100 and registers them in the electric lock control server 500 (S32). For example, the management terminal 400 receives the input of the SSID and the electric lock ID from the key manager U2, and transmits the registration request of the SSID and the electric lock ID to the electric lock control server 500 via the network N. In response to this, the registration unit 541 of the electric lock control server 500 stores the SSID 5121 included in the received registration request and the electric lock ID 5124 in the storage unit 510 as key management information 512 in association with each other.

Subsequently, the key manager U2 wirelessly connects the user terminal 200 to the wireless router 300 (S33). That is, the user terminal 200 wirelessly connects to the wireless router 300 by the operation of the key manager U2. Specifically, the user terminal 200 and the wireless router 300 establish a wireless connection.

Then, the key manager U2 associates the terminal ID of the user terminal 200 with the SSID and registers it in the electric lock control server 500 (S34). For example, the management terminal 400 receives the input of the SSID and the terminal ID from the key manager U2, and transmits the registration request of the SSID and the terminal ID to the electric lock control server 500 via the network N. In response to this, the registration unit 541 of the electric lock control server 500 stores the SSID 5121 and the terminal ID 5122 included in the received registration request in the storage unit 510 as key management information 512 in association with each other. As a result, the SSID 5121, the electronic lock ID 5124, and the terminal ID 5122 are associated with each other.

Then, the key manager U2 registers the facial feature information of the user U1 in the authentication server 600 (S35). For example, it is assumed that the key manager U2 has obtained the face image of the user U1 from the user U1. At this time, the management terminal 400 accepts the input of the face image of the user U1 from the key manager U2, and transmits the face information registration request including the face image to the authentication server 600 via the network N. In response to this, the authentication server 600 extracts face feature information from the face image included in the received face information registration request by the face detection unit 620 and the feature point extraction unit 630, and issues the user ID 611 and the face feature information 612. Is associated and registered in the face information DB 610. Further, the authentication server 600 returns the issued user ID 611 to the management terminal 400.

Subsequently, the key manager U2 associates the received user ID with the electric lock ID and registers it in the electric lock control server 500 (S36). For example, the management terminal 400 accepts the input of the user ID and the electric lock ID from the key manager U2, and transmits the registration request of the user ID and the electric lock ID to the electric lock control server 500 via the network N. In response to this, the registration unit 541 of the electric lock control server 500 stores the user ID 5123 and the electronic lock ID 5124 included in the received registration request in the storage unit 510 as key management information 512 in association with each other. As a result, the SSID 5121, the electronic lock ID 5124, the terminal ID 5122, and the user ID 5123 are associated with each other. Further, the user ID 5123 corresponds to the user ID 611 of the face information DB 610.

After that, the key manager U2 registers the area information for permitting the unlocking of the electric lock 100 in the user terminal 200 (S37). Here, the area information includes the latitude and longitude of the electric lock 100 and the radius when the latitude and longitude are centered. For example, the management terminal 400 receives the input of the area information from the key manager U2 and transmits the registration request of the area information to the user terminal 200 via the network N. In response to this, the registration unit 271 of the user terminal 200 stores the area information 213 included in the received registration request in the storage unit 210.

FIG. 10 is a sequence diagram showing the flow of the electric lock unlocking process according to the third embodiment. As a premise, it is assumed that the above-mentioned pre-registration process has been completed. For example, it is assumed that the electric lock 100 and the wireless router 300 are wirelessly connected.

First, it is assumed that the user U1 enters the front of the electric lock 100, that is, within the range of the wireless router 300 while possessing the user terminal 200. At this time, the user terminal 200 makes a wireless connection with the wireless router 300 and acquires the SSID of the wireless router 300 (S301). Then, the server communication unit 272 of the user terminal 200 transmits the acquired SSID to the electric lock control server 500 via the network N (S302). In response to this, the terminal communication unit 542 of the electric lock control server 500 receives the SSID from the user terminal 200, and acquires the terminal ID 5122 associated with the received SSID 5121 in the key management information 512. Then, the terminal communication unit 542 returns the acquired terminal ID 5122 to the user terminal 200 via the network N (S303).

The server communication unit 272 of the user terminal 200 notifies the determination unit 273 of the terminal ID received from the electric lock control server 500. Then, the determination unit 273 collates the notified terminal ID with the terminal ID 212 stored in the storage unit 210, and determines whether or not they match (S304). Here, it is assumed that they match.

Subsequently, the determination unit 273 determines whether or not the position information acquired by the position information acquisition unit 240 is within the range of the area information 213 (S305). Here, too, it is assumed that the current position information of the user terminal 200 is within the range of the area information 213.

Therefore, the determination unit 273 outputs a signal for activating the entrance button to the input / output control unit 274. Then, the input / output control unit 274 activates the "entrance button" displayed on the touch panel 230 in response to the signal (S306). After that, the input / output control unit 274 accepts the tap of the "entrance button" from the user U1 (S307). In response to this, the camera 220 captures a region (face image) including the face of the user U1 under the control of the input / output control unit 274 (S308). The input / output control unit 274 notifies the authentication control unit 275 of the captured face image.

The authentication control unit 275 transmits a face authentication request including the notified face image to the authentication server 600 via the network N (S309). The authentication server 600 performs face authentication processing based on the face image included in the face authentication request received from the user terminal 200 (S310). Specifically, the authentication unit 650 collates the face feature information extracted from the face image by the feature point extraction unit 630 with the face feature information 612, and if the degree of matching is equal to or higher than a predetermined value, the face authentication is successful. The determination is made, and the user ID 611 associated with the face feature information 612 is read from the face information DB 610. Then, the authentication unit 650 transmits the face authentication result including the read user ID 611 to the user terminal 200 via the network N (S311).

The authentication control unit 275 of the user terminal 200 receives the face authentication result from the authentication server 600, and recognizes that the face authentication was successful from the face authentication result. Therefore, the authentication control unit 275 notifies the server communication unit 272 of the face authentication result. Then, the server communication unit 272 transmits the user ID included in the face authentication result, the acquired SSID, and the terminal ID 212 to the electric lock control server 500 via the network N (S312).

The acquisition unit 543 of the electric lock control server 500 receives the user ID, the SSID, and the terminal ID from the user terminal 200. Then, the unlocking unit 544 collates the received set of the SSID, the terminal ID, and the user ID with the set of the SSID 5121, the terminal ID 5122, and the user ID 5123 in the key management information 512 (S313). Here, it is assumed that the collation is successful. Therefore, the unlocking unit 544 identifies the electronic lock ID 5124 associated with the set of the collated SSID 5121, the terminal ID 5122, and the user ID 5123 (S314).

The unlocking unit 544 transmits an unlocking signal to the electric lock 100 corresponding to the specified electronic lock ID 5124 via the network N and the wireless router 300 (S315). The wireless communication unit 102 of the electric lock 100 receives the unlock signal from the electric lock control server 500 and notifies the lock / unlock control unit 101 of the unlock signal. The lock / unlock control unit 101 unlocks the key (electric lock 100) of the door 10 in response to the notified unlock signal (S316).

Further, the terminal communication unit 542 transmits an unlock message indicating that the electric lock 100 corresponding to the electric lock ID specified in step S314 has been unlocked to the user terminal 200 via the network N (S317). ). The input / output control unit 274 of the user terminal 200 displays the received unlocking message on the touch panel 230 (S318).

In this way, in the present embodiment, the electric lock 100 is unlocked when the above-mentioned conditions 1 and 2 are satisfied. That is, the user U1 and the user terminal 200 that are permitted to unlock the electric lock 100 are registered in advance, and the user terminal 200 is located in a region defined by the position information of the electric lock 100 and the radius centered on the position information. Is a condition for unlocking. Therefore, the lock cannot be unlocked from a place away from the electric lock 100. Therefore, security can be maintained.

Further, for example, in Patent Document 1, in order to unlock an electric lock using a user terminal, it is necessary to connect the user terminal and the electric lock via short-range wireless communication such as Bluetooth (registered trademark). Therefore, the purchase cost of a device such as a communication device for short-range wireless communication is incurred. In addition, construction work was required to bury the purchased communication equipment, etc. on the door side. Besides that, a tablet terminal for notifying the user that the door was unlocked and a camera were required to realize face recognition. In order to prevent theft of tablet terminals and cameras, it was also necessary to bury them in doors, walls, and the like. In the present embodiment, it is not necessary to purchase or construct these devices, and the introduction burden can be reduced. Further, since the unlock message can be displayed on the user terminal 200, the user U1 can easily grasp that the lock has been unlocked.

<Embodiment 4>
The fourth embodiment is a modification of the third embodiment described above. In the fourth embodiment, the electric lock control server performs the determination processing of the condition 1 and the condition 2, and also controls (relays) the face authentication processing. Since the configuration of the electric lock control system 1000 according to the fourth embodiment is the same as that of FIG. 5 described above, the illustration is omitted. However, the user terminal 200 of FIG. 5 is referred to as a user terminal 200a in the fourth embodiment, and the electric lock control server 500 of FIG. 5 is referred to as an electric lock control server 500a in the fourth embodiment. Further, in the following, the differences from the above-described third embodiment will be mainly described, and the description of overlapping configurations will be omitted as appropriate.

FIG. 11 is a block diagram showing a configuration of the electric lock control server 500a according to the fourth embodiment. The storage unit 510 of the electric lock control server 500a stores the program 511a, the key management information 512, and the set of the electronic lock ID 5131 and the area information 5132. The program 511a is a computer program in which the processing in the electric lock control server 500a of the electric lock control method according to the fourth embodiment is implemented. Further, the electronic lock ID 5131 and the area information 5132 are associated with each other. That is, it is shown that the area information 5132 is defined for each electronic lock ID 5131. The area information 5132 is the same information as the above-mentioned area information 213.

The control unit 540 of the electric lock control server 500a includes a registration unit 541a, a terminal communication unit 542a, an authentication control unit 543a, an unlocking unit 544, and a determination unit 545. In addition to the function of the registration unit 541 described above, the registration unit 541a receives the area information for each electronic lock ID, and stores the received electronic lock ID 5131 and the area information 5132 in the storage unit 510 in association with each other.

The terminal communication unit 542a performs processing including transmission / reception of data to / from the user terminal 200a via the network N. For example, the terminal communication unit 542a receives the SSID, the terminal ID, and the location information from the user terminal 200a.

The determination unit 545 determines whether or not the set of the SSID and the terminal ID received by the terminal communication unit 542a is included in the key management information 512. This determination can be said to be a modification of condition 1. Further, the determination unit 545 determines whether or not the position information received by the terminal communication unit 542a is within the range of the area information 5132. This determination can be said to be a modification of condition 2.

Further, when the determination unit 545 determines that the modification of the condition 1 and the condition 2 is satisfied, the terminal communication unit 542a transmits a face authentication permission signal to the user terminal 200a via the network N. Here, the permission signal may be a signal that activates the "entrance button". The permission signal is an example of notification.

Therefore, it can be said that the terminal communication unit 542a gives a notification when the determination unit 545 determines that the SSID 5121 stored in the storage unit 510 and the acquired SSID match. Further, the terminal communication unit 542a refers to the storage unit 510 and notifies when the determination unit 545 determines that the terminal ID associated with the acquired SSID matches the acquired terminal ID. It can be said that. Further, when the terminal communication unit 542a refers to the storage unit 510, the acquired position information is included in the range of the area information 5132 corresponding to the electric lock ID 5124 (5131) associated with the acquired SSID. When the determination is made by the determination unit 545, it can be said that the notification is given.

When the authentication control unit 543a receives the face recognition request from the user terminal 200a via the network N, the authentication control unit 543a transmits the face recognition request to the authentication server 600 via the network N. Then, the authentication control unit 543a receives (acquires) the face authentication result from the authentication server 600 via the network N. The authentication control unit 543a notifies the unlocking unit 544 of the face authentication result.

When the face authentication result shows success, the unlocking unit 544 uses the set of the user ID included in the face authentication result and the SSID and the terminal ID received by the terminal communication unit 542a as the SSID 5121 and the terminal ID 5122 of the key management information 512. And collate with the set of user ID 5123. If they match, the unlocking unit 544 identifies the associated electronic lock ID 5124 and transmits a release signal to the electric lock 100 as described above.

FIG. 12 is a block diagram showing the configuration of the user terminal 200a according to the fourth embodiment. The storage unit 210 of the user terminal 200a stores the program 211a and the terminal ID 212. The program 211a is a computer program in which the processing in the user terminal 200a of the electric lock control method according to the fourth embodiment is implemented.

The control unit 270 of the user terminal 200a includes a server communication unit 272a, an input / output control unit 274, and an authentication control unit 275a. The server communication unit 272a transmits the SSID acquired from the wireless router 300, the terminal ID 212, and the position information acquired by the position information acquisition unit 240 to the electric lock control server 500a via the network N. Further, the server communication unit 272a receives the permission signal from the electric lock control server 500a via the network N and notifies the input / output control unit 274. When the input / output control unit 274 receives the permission signal from the server communication unit 272a, the input / output control unit 274 activates the "entrance button" displayed on the touch panel 230. The authentication control unit 275a transmits a face authentication request including a face image notified from the input / output control unit 274 to the electric lock control server 500a via the network N.

FIG. 13 is a flowchart showing the flow of the pre-registration process according to the fourth embodiment. Since steps S31 to S36 are the same as those in FIG. 9 described above, the description thereof will be omitted. In step S37a, the key manager U2 registers the area information for permitting the unlocking of the electric lock 100 in the electric lock control server 500a. For example, the management terminal 400 receives the input of the area information and the electric lock ID from the key manager U2, and transmits the registration request of the area information and the electric lock ID to the electric lock control server 500a via the network N. In response to this, the registration unit 541a of the electric lock control server 500a stores the area information 5132 and the electric lock ID 5131 included in the received registration request in the storage unit 510.

FIG. 14 is a sequence diagram showing the flow of the electric lock unlocking process according to the fourth embodiment. First, the user terminal 200a wirelessly connects to the wireless router 300 and acquires the SSID of the wireless router 300 (S301). Then, the server communication unit 272a of the user terminal 200a transmits the acquired SSID, the terminal ID 212, and the location information acquired by the location information acquisition unit 240 to the electric lock control server 500a via the network N (S302a). In response to this, the terminal communication unit 542a of the electric lock control server 500a receives the SSID, the terminal ID and the position information from the user terminal 200a.

The determination unit 545 collates the set of the SSID and the terminal ID received by the terminal communication unit 542a with the set of the SSID 5121 and the terminal ID 5122 included in the key management information 512, and determines whether or not they match (S303a). Here, it is assumed that they match. Further, at this time, the determination unit 545 may specify the electronic lock ID 5124 associated with the matching set of SSID 5121 and terminal ID 5122.

Subsequently, the determination unit 545 determines whether or not the position information received by the terminal communication unit 542a is within the range of the area information 5132 associated with the specified electronic lock ID 5124 (5131) (S304a). Here, too, it is assumed that the current position information of the user terminal 200a is within the range of the area information 5132. Therefore, the terminal communication unit 542a transmits a permission signal for activating the "entrance button" to the user terminal 200a via the network N (S305a).

The server communication unit 272a of the user terminal 200a notifies the input / output control unit 274 of the permission signal received from the electric lock control server 500a. When the input / output control unit 274 receives the permission signal from the server communication unit 272a, the input / output control unit 274 activates the "entrance button" displayed on the touch panel 230 (S306). After that, the input / output control unit 274 accepts the tap of the "entrance button" from the user U1 (S307). In response to this, the camera 220 captures a region (face image) including the face of the user U1 under the control of the input / output control unit 274 (S308). The input / output control unit 274 notifies the authentication control unit 275a of the captured face image. The authentication control unit 275a transmits a face authentication request including a face image notified from the input / output control unit 274 to the electric lock control server 500a via the network N (S309a).

The authentication control unit 543a of the electric lock control server 500a transmits the face authentication request received from the user terminal 200a to the authentication server 600 via the network N (S309b). The authentication server 600 performs face authentication processing in the same manner as described above based on the face image included in the face authentication request received from the electric lock control server 500a (S310). The authentication control unit 543a receives (acquires) the face recognition result from the authentication server 600 via the network N (S311a), and notifies the face recognition result to the unlocking unit 544.

When the face authentication result shows success, the unlocking unit 544 uses the set of the user ID included in the face authentication result and the SSID and the terminal ID received by the terminal communication unit 542a as the SSID 5121 and the terminal ID 5122 of the key management information 512. And collate with the set of user ID 5123 (S313a). Here, it is assumed that they match, and thereafter, it is the same as steps S314 to S318 in FIG.

As described above, the same effect as that of the above-described third embodiment can be obtained in this embodiment as well.

<Embodiment 5>
The fifth embodiment is a modification of the third or fourth embodiment described above. In the fifth embodiment, the electronic lock control server enumerates the electric locks (doors) that are candidates for unlocking based on the position information of the user terminal, and then the electric lock according to the wireless router to which the user terminal is wirelessly connected. It narrows down. In the following description, the above-described fourth embodiment will be described as an improvement, but the present invention can also be applied to the third embodiment.

FIG. 15 is a block diagram showing the overall configuration of the electric lock control system 2000 according to the fifth embodiment. The electric lock control system 2000 targets a plurality of doors 10a to 10c as control targets. Each of the plurality of doors 10a to 10c is provided with an electric lock 100a to 100c. Here, each of the electric locks 100a to 100c has the same configuration as the electric lock 100 described above. Further, it is assumed that each of the electric locks 100a to 100c is wirelessly connected to different wireless routers 300a to 300c. Specifically, the electric lock 100a is wirelessly connected to the wireless router 300a, the electric lock 100b is wirelessly connected to the wireless router 300b, and the electric lock 100c is wirelessly connected to the wireless router 300c.

The user terminal 200b is an improvement of the above-mentioned user terminal 200a. Here, it is shown that the user terminal 200b is wirelessly connected to the wireless router 300b, but it may not be connected or may be wirelessly connected to another wireless router.

Further, the electric lock control server 500b is an improvement of the above-mentioned electric lock control server 500a.

FIG. 16 is a sequence diagram showing the flow of the electric lock unlocking process according to the fifth embodiment. As a premise, it is assumed that the user terminal 200b is not connected to any of the wireless routers 300a to 300c. Further, it is assumed that the electric lock control server 500b stores the area information in each of the electric locks 100a to 100c. In addition, the range of each area information shall overlap.

At this time, the user terminal 200b acquires the current position information by the position information acquisition unit 240 (S501). Then, the user terminal 200b transmits the acquired position information to the electric lock control server 500b via the network N (S502).

The electric lock control server 500b receives the position information from the user terminal 200b. Then, the electric lock control server 500b identifies a plurality of electric lock IDs in the vicinity based on the received position information (S503). For example, it is assumed that the electric lock control server 500b identifies a plurality of electronic lock IDs 5131 whose position information is within the range of the area information 5132. Therefore, the electric lock control server 500b transmits a list of the specified plurality of electronic lock IDs 5131 to the user terminal 200b via the network N (S504).

The user terminal 200b receives a list of electronic locks from the electric lock control server 500b, and displays door information (door candidates) corresponding to each electronic lock on the touch panel 230 (S505). For example, the touch panel 230 assumes that the doors 10a to 10c are displayed as door candidates. As a result, the user U1 can recognize that the plurality of doors can be unlocked.

Here, for example, it is assumed that the user U1 possessing the user terminal 200b has moved near the door 10b. At this time, the user terminal 200b is wirelessly connected to the wireless router 300b and acquires the SSID of the wireless router 300b (S301a). Hereinafter, the processing is performed in the same manner as in steps S302a to S304a of FIG. 14 described above. Then, the determination unit 545 of the electric lock control server 500b identifies the electronic lock ID 5124 associated with the pair of the matching SSID 5121 and the terminal ID 5122 (S304b). Here, it is assumed that the electronic lock ID corresponding to the electric lock 100b is specified. Therefore, the terminal communication unit 542a of the electric lock control server 500b transmits a permission signal for activating the "entrance button" to the user terminal 200b via the network N (S305b). At this time, the terminal communication unit 542a includes the electronic lock ID specified in step S304b in the permission signal.

The server communication unit 272a of the user terminal 200b notifies the input / output control unit 274 of the permission signal received from the electric lock control server 500b. When the input / output control unit 274 receives the permission signal from the server communication unit 272a, the input / output control unit 274 selects a door candidate (door 10b) corresponding to the electronic lock ID included in the permission signal, and "entrance" corresponding to the selected door candidate. Activate the "button" (S306b). Therefore, the input / output control unit 274 accepts the tap of the "entrance button" from the user U1 (S307). That is, the user U1 taps the "entrance button" of the door 10b. After that, the processing after step S308 in FIG. 14 described above is performed on the electric lock 100b.

As described above, in the present embodiment, the door candidates that can be automatically unlocked by the electric lock control system 2000 are narrowed down from the plurality of door candidates according to the movement of the user terminal 200b. Therefore, the user U1 can unlock the electronic lock and enter the venue without feeling uncomfortable.

It should be noted that steps S504 and S505 do not necessarily have to be executed. In that case, when the permission signal is notified by step S305b, the user terminal 200b shall tremble due to the vibration function. This makes it easier for the user U1 to recognize the automatically selected door candidate.

<Embodiment 6>
The sixth embodiment is a modification of the fifth embodiment described above. In the sixth embodiment, when a plurality of electronic locks are wirelessly connected to one wireless router, the electronic lock to be unlocked is specified by the user's selection. In the following description, the above-described fourth embodiment will be described as an improvement, but the present invention can also be applied to the third embodiment.

FIG. 17 is a block diagram showing the overall configuration of the electric lock control system 2000a according to the sixth embodiment. The electric lock control system 2000a targets a plurality of doors 10a to 10c similar to the above-described fifth embodiment. However, it is assumed that each of the electric locks 100a to 100c is wirelessly connected to the same wireless router 300.

The user terminal 200c is an improvement of the above-mentioned user terminal 200a. Here, it is shown that the user terminal 200c is wirelessly connected to the wireless router 300, but it may not be connected.

Further, the electric lock control server 500c is an improvement of the above-mentioned electric lock control server 500a. That is, when a plurality of electric lock IDs are associated with the acquired SSID, the terminal communication unit 542a of the electric lock control server 500c transmits the plurality of electric lock IDs to the user terminal 200c. Then, after receiving the selection of one of the plurality of electric lock IDs from the user terminal 200c, the terminal communication unit 542a performs the above notification when the acquired position information is included in the range of the area information.

FIG. 18 is a sequence diagram showing the flow of the electric lock unlocking process according to the sixth embodiment. As a premise, it is assumed that the electric lock control server 500c is associated with the electric lock ID corresponding to each of the electric locks 100a to 100c and the SSID of the wireless router 300.

At this time, the user terminal 200c makes a wireless connection with the wireless router 300 and acquires the SSID of the wireless router 300 (S601). Then, the server communication unit 272a of the user terminal 200c transmits the acquired SSID to the electric lock control server 500c via the network N (S602). In response to this, the terminal communication unit 542a of the electric lock control server 500c receives the SSID from the user terminal 200c.

Here, the terminal communication unit 542a identifies a plurality of electric lock IDs based on the received SSID (S603). For example, it is assumed that the electric lock control server 500c identifies a plurality of electronic lock IDs 5123 associated with the received SSID. Therefore, the electric lock control server 500c transmits a list of the specified plurality of electronic lock IDs 5131 to the user terminal 200c via the network N (S604).

The user terminal 200c receives a list of electronic locks from the electric lock control server 500c, and displays door information (door candidates) corresponding to each electronic lock on the touch panel 230 (S605). For example, the touch panel 230 assumes that the doors 10a to 10c are displayed as door candidates.

Here, it is assumed that the user U1 taps the door 10c. That is, the user terminal 200c accepts the selection of the door 10c from the user U1 (S606). As a result, the user terminal 200c identifies the selected electric lock ID. Then, the user terminal 200c transmits the acquired SSID, the terminal ID 212, the position information acquired by the position information acquisition unit 240, and the selected electronic lock ID to the electric lock control server 500c via the network N (S607). ). In response to this, the terminal communication unit 542a of the electric lock control server 500c receives the SSID, the terminal ID, the position information, and the electric lock ID from the user terminal 200c.

The determination unit 545 collates the set of the SSID, the terminal ID, and the electric lock ID received by the terminal communication unit 542a with the set of the SSID 5121, the terminal ID 5122, and the electronic lock ID 5124 included in the key management information 512, and determines whether or not they match. Is determined (S608). Here, it is assumed that they match. After that, the processing after step S304a in FIG. 14 described above is performed on the electric lock 100c.

As described above, in the present embodiment, even when a plurality of electronic locks are wirelessly connected to one wireless router, the electronic locks can be unlocked in the same manner as described above by the user's choice.
