Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0010] In the following embodiments, a locking and unlocking device using a digital key is disclosed.

[0011] [Summary of the Present Disclosure] In the embodiment shown in FIG. 1, a front door 60 that can be locked and unlocked by a card key storing a digital key is installed in a house 10, and the front door 60 is typically locked and unlocked by a locking and unlocking device 100 built in the front door 60. The locking and unlocking device 100 can receive, for example, an infrared signal transmitting a digital key transmitted from the card key, a wireless signal transmitting a digital key transmitted from a portable information terminal 30 such as a smartphone, and locks and unlocks the front door 60 with the received digital key.

[0012] Regarding the front door 60 provided with the locking and unlocking device 100 using such a digital key, for example, a resident staying at home in the house 10 makes an emergency call due to illness, injury, accident, fire, disaster, etc., but cannot move and cannot unlock the front door 60, and there is a case where emergency team members who have arrived at the house 10 cannot enter the house 10. In particular, in a situation where the number of single-person households including the younger generation and the elderly is increasing, such cases are expected to increase.

[0013] In the embodiments described below, as shown in FIG. 1, when a resident of the house 10 makes an emergency call to the emergency call receiving agency by dialing "119" using the portable information terminal 30 ( "(1) Emergency call"), the emergency service server 20 of the emergency call receiving agency first contacts the nearest fire station to issue a dispatch order ( "(2) Dispatch order"). The dispatched ambulance 50, for example, periodically acquires the position information of the current position of the ambulance 50 using GPS (Global Positioning System) or the like, and transmits the acquired position information to the emergency service server 20 ( "(3) Position information").

[0014] On the other hand, the emergency service server 20 transmits predetermined housing information such as the address of the house 10 and the name of the resident to the digital key service server 40 that can control the unlocking device 100, and the digital key service server 40 determines whether the unlocking device 100 managed by the digital key service server 400 is installed in the house 10 based on the received housing information. When it is determined that the unlocking device 100 installed in the house 10 is managed by the digital key service server 40, cooperation with the emergency service server 20 is started, and vehicle information such as the position information of the ambulance 50 is acquired from the emergency service server 20 ( "(4) Emergency cooperation"). After the issuance and registration of the digital key of the unlocking device 100 are requested by the resident (user), digital key information (number of the digital key, name of the user, address, etc.) is registered in the digital key service server 40.

[0015] When the ambulance 50 approaches within a predetermined range 70 from the house 10, the digital key service server 40 determines that the ambulance 50 has arrived within the predetermined range 70 from the house 10 based on the position information of the ambulance 50 acquired from the emergency service server 20, and transmits an unlocking signal to the unlocking device 100 via the Internet, for example ( "(5) Unlocking signal"). Upon receiving the unlocking signal, the unlocking device 100 unlocks the front door 60, and the emergency team members can enter the house 10 through the unlocked front door 60 and rescue the resident.

[0016] In the embodiment shown in FIG. 1, the digital key service server 40 that determines that the ambulance 50 has approached within a predetermined range 70 from the house 10 transmits an unlocking signal to the unlocking device 100. However, the present disclosure is not limited thereto. For example, as shown in FIG. 2, when the digital key service server 40 determines that the ambulance 50 has arrived within a predetermined range 70 from the house 10 based on the position information of the ambulance 50 acquired from the emergency service server 20, it may transmit an unlocking signal to the portable information terminal 30 ("(5a) Unlocking signal"). When receiving the unlocking signal from the digital key service server 40, the portable information terminal 30 may transmit the unlocking signal to the unlocking device 100 ("(6a) Unlocking signal"). Thereby, even when the unlocking device 100 is not connected to a network such as the Internet, the digital key service server 40 can transmit an unlocking signal to the unlocking device 100 via the resident's portable information terminal 30.

[0017] Also, in the illustrated embodiment, the resident uses the portable information terminal 30 to send an emergency report to the emergency report receiving agency. However, the present disclosure is not limited thereto. For example, it is similarly applicable to a case where an emergency report is made based on an image inside the house 10 captured by a camera of the monitoring system of the house 10. In this case, an information processing terminal inside the house of the monitoring system can function in the same manner as the portable information terminal 30.

[0018] Here, the portable information terminal 30 and the digital key service server 40 may each be realized by a computing device such as a server, a personal computer (PC), a smartphone, or a tablet. For example, they may have a hardware configuration as shown in FIG. 3. That is, the portable information terminal 30 and the digital key service server 40 each have a drive device 31, a storage device 32, a memory device 33, a processor 34, a user interface (UI) device 35, and a communication device 36 that are interconnected via a bus B.

[0019] Programs or instructions for implementing various functions and processes in the mobile information terminal 30 and the digital key service server 40 may be stored in a removable storage medium such as a CD-ROM (Compact Disk-Read Only Memory) or a flash memory. When the storage medium is set in the drive device 31, the program or instruction is installed from the storage medium via the drive device 31 into the storage device 32 or the memory device 33. However, the program or instruction does not necessarily have to be installed from the storage medium and may be downloaded from any external device via a network or the like.

[0020] The storage device 32 is realized by a hard disk drive or the like and stores files, data, etc. used for the execution of the installed program or instruction together with the installed program or instruction.

[0021] The memory device 33 is realized by a random access memory, a static memory, etc. When the program or instruction is activated, the program or instruction, data, etc. are read from the storage device 32 and stored. The storage device 32, the memory device 33, and the removable storage medium may be collectively referred to as a non-transitory storage medium.

[0022] The processor 34 may be realized by one or more CPUs (Central Processing Units), GPUs (Graphics Processing Units), processing circuits, etc. that may be composed of one or more processor cores, and executes various functions and processes of the mobile information terminal 30 and the digital key service server 40 according to data such as programs, instructions, and parameters necessary for executing the programs or instructions stored in the memory device 33.

[0023] The user interface (UI) device 35 may be composed of input devices such as a keyboard, a mouse, a camera, a microphone, etc., output devices such as a display, a speaker, a headset, a printer, etc., and input / output devices such as a touch panel, and realizes an interface between the user and the mobile information terminal 30 and the digital key service server 40 respectively. For example, the user may operate the GUI (Graphical User Interface) displayed on the display or the touch panel by operating a keyboard, a mouse, etc., and operate the mobile information terminal 30 and the digital key service server 40.

[0024] The communication device 36 is realized by various communication circuits that execute wired and / or wireless communication processing with communication networks such as external devices, the Internet, a LAN (Local Area Network), and a cellular network.

[0025] However, the above-described hardware configuration is merely an example, and the mobile information terminal 30 and the digital key service server 40 according to the present disclosure may be realized by any other appropriate hardware configuration.

[0026] Also, the unlocking device 100 may be realized by an information processing device such as a processing circuit, and may have, for example, a hardware configuration as shown in FIG. 4. That is, the unlocking device 100 has a memory device 101, a processor 102, and a communication device 103.

[0027] The memory device 101 is realized by a random access memory, a static memory, etc., and reads and stores programs, data, etc. The memory device 101 may be generically referred to as a non-temporary storage medium.

[0028] The processor 102 may be realized by a CPU, a processing circuit, etc., and executes various functions and processes of the unlocking device 100 according to programs stored in the memory device 103, data such as parameters necessary for executing the program, etc.

[0029] The communication device 103 is realized by various communication circuits that execute wired and / or wireless communication processing with communication networks such as external devices, the Internet, a LAN (Local Area Network), and a cellular network.

[0030] However, the above-described hardware configuration is merely an example, and the unlocking and locking device 100 according to the present disclosure may be realized by any other appropriate hardware configuration. Further, the unlocking and locking device 100 may be an integrated type integrated with the front door 60, or may be a retrofitted type attached to the front door 60 and having a mechanism for controlling the thumb turn of the front door 60. Regarding the control of the key, in the integrated type unlocking and locking device 100, in addition to the normal wireless control key unlocking operation by emergency responders or the like, it is assumed that an emergency unlocking operation is performed by numeric keypad input. On the other hand, in the retrofitted type unlocking and locking device 100, since it is often installed inside the front door 60 (near the doorknob, etc.), it is assumed that an unlocking signal is received by emergency wireless.

[0031] [Unlocking and Locking Device] Next, the unlocking and locking device 100 according to an embodiment of the present disclosure will be described. FIG. 5 is a block diagram showing the functional configuration of the unlocking and locking device 100 according to an embodiment of the present disclosure. As shown in FIG. 5, the unlocking and locking device 100 has a communication unit 110 and an unlocking and locking control unit 120. Each functional unit of the communication unit 110 and the unlocking and locking control unit 120 may be realized by a computer program stored in the memory device 101 of the unlocking and locking device 100 being executed by the processor 102.

[0032] The communication unit 110 receives an unlocking signal transmitted in response to the arrival of an emergency vehicle within a predetermined range from the installation position of the unlocking target. Here, the emergency vehicle is not limited to the ambulance 50 described above, and includes vehicles of emergency institutions such as police cars, white vans, fire trucks, bicycles, vehicles of security companies, medical facilities, nursing facilities, vehicles of infrastructure-related companies such as electric power companies and gas companies, etc., and vehicles of institutions, companies, facilities, etc. that have the legitimacy to enter the house 10 in an emergency.

[0033] For example, in the embodiment shown in FIG. 1, the digital key service server 40 in emergency cooperation with the emergency service server 20 periodically obtains location information from the ambulance 50 traveling towards the house 10, and when it is determined based on the obtained location information that the ambulance 50 has reached within a predetermined range (for example, within a radius of 100 m from the house 10) from the house 10, it transmits an unlocking signal for unlocking the front door 60 to the unlocking and locking device 100. The communication unit 110 receives the unlocking signal transmitted from the digital key service server 40 and passes the received unlocking signal to the unlocking and locking control unit 120.

[0034] For example, the communication unit 110 may receive the unlocking signal transmitted from the digital key service server 40 via the Internet through the Wi-Fi within the house 10, via the cellular network, or via any other wired / wireless network.

[0035] Alternatively, in the embodiment shown in FIG. 2, the digital key service server 40 in emergency cooperation with the emergency service server 20 periodically obtains location information from the ambulance 50 traveling towards the house 10, and when it is determined based on the obtained location information that the ambulance 50 has reached within a predetermined range (for example, within a radius of 100 m from the house 10) from the house 10, it transmits an unlocking signal for unlocking the front door 60 to the portable information terminal 30. When the portable information terminal 30 receives the unlocking signal from the digital key service server 40, it transmits the received unlocking signal to the unlocking and locking device 100. Then, the communication unit 110 receives the unlocking signal transmitted from the portable information terminal 30 and passes the received unlocking signal to the unlocking and locking control unit 120.

[0036] For example, the communication unit 110 may receive the unlocking signal transmitted from the portable information terminal 30 via the Wi-Fi within the house 10, via the cellular network, or via any other wired / wireless network.

[0037] In one embodiment, the communication unit 110 may receive an unlocking signal from an information processing terminal that determines that an emergency vehicle has arrived within a predetermined range from the installation position of the unlocking target based on the position information of the emergency vehicle. That is, instead of the digital key service server 40, the mobile information terminal 30 may be made to perform the approach determination of the emergency vehicle. Specifically, when unlocking the unlocking device 100 via the mobile information terminal 30 described above with reference to FIG. 2, the digital key service server 40 may transmit the position information of the ambulance 50 to the mobile information terminal 30 instead of the unlocking signal, and cause the mobile information terminal 30 to determine whether the ambulance 50 has reached within a predetermined range from the house 10 based on the acquired position information. When the mobile information terminal 30 determines that the ambulance 50 has reached within a predetermined range from the house 10 based on the position information, the mobile information terminal 30 may transmit an unlocking signal to the unlocking device 100 to unlock the front door 60.

[0038] In response to receiving the unlocking signal, the unlocking control unit 120 unlocks the unlocking target. For example, when the unlocking signal is acquired from the digital key service server 40 or the mobile information terminal 30, the unlocking control unit 120 verifies the acquired unlocking signal, and after the unlocking signal is verified, unlocks the front door 60. Here, the specific unlocking of the key of the front door 60 may be performed by program control of the key by the unlocking control unit 120, or may be performed by motor control of the doorknob (thumb turn).

[0039] For example, the verification may be to determine whether the data encrypted in the unlocking signal matches the unlocking data pre-stored in the unlocking and locking device 100. For example, the unlocking and locking device 100 receives the encrypted unlocking signal (key data), decrypts the pre-stored unlocking signal (key data) in the unlocking and locking device 100 in advance, and then verifies (compares) and determines whether they match. When the data decrypted from the unlocking signal matches the unlocking data, the unlocking and locking control unit 120 determines that the acquired unlocking signal is legitimate and unlocks the front door 60. On the other hand, when the data decrypted from the unlocking signal does not match the unlocking data, the unlocking and locking control unit 120 determines that the acquired unlocking signal is not legitimate and maintains the locking of the front door 60. Here, the keys for encryption and decryption may be realized using a public key encryption method or the like, or may be realized by a common key encryption method. In addition, in order to manage confidential information such as keys, it may be stored in a tamper-resistant device or the like, or may be stored in the memory of the device. The key storage method can be determined based on cost-effectiveness, cost, security policy, etc.

[0040] In this way, when the emergency vehicle arrives within a predetermined range from the installation position of the object to be unlocked and locked, the unlocking and locking device 100 can remotely unlock the front door 60 by the unlocking signal transmitted from the digital key service server 40.

[0041] [Digital Key Service Server] Next, the digital key service server 40 according to an embodiment of the present disclosure will be described. FIG. 6 is a block diagram showing the functional configuration of the digital key service server 40 according to an embodiment of the present disclosure. As shown in FIG. 6, the digital key service server 40 includes an acquisition unit 41, a storage unit 42, a determination unit 43, and a transmission unit 44. Each functional unit of the acquisition unit 41, the storage unit 42, the determination unit 43, and the transmission unit 44 may be realized by a computer program stored in the memory device 33 of the digital key service server 40 being executed by the processor 34.

[0042] The acquisition unit 41 acquires the position information of the emergency vehicle. For example, the emergency vehicle may be equipped with a positioning device (such as a GPS positioning device, etc.) for measuring the current position, and the position information of the emergency vehicle may be acquired. The position information acquired at a predetermined acquisition timing may be transmitted from the emergency vehicle to the emergency service server 20. Alternatively, the crew of the emergency vehicle may use a mobile information terminal equipped with a positioning function to acquire the position information of the emergency vehicle. The position information acquired at a predetermined acquisition timing may be transmitted from the crew's mobile information terminal to the emergency service server 20. The acquisition unit 41 passes the acquired position information to the determination unit 43. Also, the acquisition unit 41 acquires notification information such as the address of the house 10 where the unlocking target object is installed and the name of the resident.

[0043] The storage unit 42 stores personal information and the like set at the time of registration of the unlocking device 100. The personal information may indicate, for example, the key number of the key to be unlocked by the unlocking device 100, the address of the house 10, the position information, the unlocking password of the key, and the like.

[0044] The determination unit 43 determines whether the emergency vehicle has arrived within a predetermined range from the installation position of the unlocking target object based on the position information. For example, the determination unit 43 checks the position information of the ambulance 50 acquired at a predetermined acquisition timing from the acquisition unit 41, and acquires the address and the like of the unlocking target object from the storage unit 42, and determines whether the ambulance 50 has reached within a predetermined range (for example, within a radius of 100 m from the house 10, etc.) from the installation position of the house 10. Then, when the ambulance 50 reaches within a predetermined range from the installation position of the house 10, the determination unit 43 notifies the transmission unit 44 of the determination result.

[0045] When the transmission unit 44 determines that the emergency vehicle has arrived within a predetermined range from the installation position of the unlocking target object, it transmits an unlocking signal to the unlocking device 100. For example, when the determination unit 42 determines that the ambulance 50 has reached within a predetermined range from the house 10 and notifies the transmission unit 43 of the determination result, the transmission unit 43 transmits an unlocking signal to the unlocking device 100. Here, the unlocking signal may be transmitted to the unlocking device 100 via the Internet, or may be transmitted to the portable information terminal 30 via the Internet and then transmitted from the portable information terminal 30 to the unlocking device 100.

[0046] In this way, when the digital key service server 40 determines that the emergency vehicle has arrived within a predetermined range from the installation position of the unlocking target object, it can transmit an unlocking signal to the unlocking device 100 to remotely unlock the front door 60.

[0047] [Digital Key Control Process] Next, the digital key control process according to an embodiment of the present disclosure will be described. The digital key control process can be realized by the unlocking device 100 mounted on the front door in the house 10, the portable information terminal 30 of the resident of the house 10, the emergency service server 20 operated by the emergency agency, the ambulance 50, and the digital key service server 40.

[0048] FIG. 7 is a sequence diagram showing the digital key control process according to an embodiment of the present disclosure. As shown in FIG. 7, in step S101, the portable information terminal 30 transmits an emergency notification regarding illness, injury, accident, fire, disaster, etc. to the emergency service server 20. For example, a third party such as a resident of the house 10 or a neighboring resident may operate the communication function of the portable information terminal 30 to transmit an emergency notification for requesting the call of the ambulance 50 to the emergency notification receiving agency.

[0049] In step S102, the emergency service server 20 transmits a dispatch order to the ambulance 50.

[0050] In step S103, the emergency service server 20 transmits the vehicle information of the ambulance 50 and the notification information such as the name of the resident who requested the dispatch and the address of the house 10 to the digital key service server 40. Based on the received notification information, the digital key service server 40 determines whether the house 10 that requested the dispatch is managed by the digital key service server 40. This determination may be made, for example, based on customer information pre-stored in the digital key service server 40. The digital key service server 40 may determine whether the house 10 is managed by the digital key service server 40 based on whether the house 10 and / or the resident that requested the dispatch is registered in the customer information. For example, the fixed telephone number and / or mobile telephone number of the house 10 and / or the resident may be registered. Also, an identification number such as the serial number of the unlocking / locking device 100 registered in the digital key service server 40 in association with the address of the house 10 and a key value (key password) may be registered, and the collation result may be transmitted. When it is determined that the house 10 is managed by the digital key service server 40, the digital key service server 40 starts an emergency cooperation with the emergency institution and requests the position information of the ambulance 50 from the emergency service server 20.

[0051] In step S104, the emergency service server 20 acquires the position information from the ambulance 50. For example, the position information can be acquired periodically at a predetermined acquisition timing.

[0052] In step S105, the emergency service server 20 transmits the position information of the ambulance 50 to the digital key service server 40. Steps S104 and S105 are repeated at a predetermined acquisition timing until the ambulance 50 arrives at the house 10.

[0053] In step S106, each time the digital key service server 40 acquires the position information, it determines whether the ambulance 50 has reached within a predetermined range from the house 10. When it is determined that the ambulance 50 has reached within a predetermined range from the house 10, the digital key service server 40 determines that the ambulance 50 has arrived at the house 10.

[0054] In step S107, the digital key service server 40 transmits an unlocking signal to the unlocking device 100 to unlock the front door 60.

[0055] FIG. 8 is a sequence diagram showing digital key control processing according to another embodiment of the present disclosure. In the embodiment shown in FIG. 7, corresponding to FIG. 1, the digital key service server 40 transmitted an unlocking signal to the unlocking device 100. In the embodiment shown in FIG. 8, corresponding to FIG. 2, the digital key service server 40 transmits an unlocking signal to the unlocking device 100 via the portable information terminal 30. Steps S201 to S206 in FIG. 8 are the same as steps S101 to S106 in FIG. 7, and duplicate explanations are omitted.

[0056] In step S207, the digital key service server 40 transmits an unlocking signal to the portable information terminal 30.

[0057] In step S208, the portable information terminal 30 transmits an unlocking signal to the unlocking device 100 to unlock the front door 60.

[0058] FIG. 9 is a schematic diagram showing digital key control processing according to another embodiment of the present disclosure. In the embodiment shown in FIG. 9, (1) emergency notification, (2) deployment order, (3) location information, and (4) emergency cooperation are the same as those in the embodiments shown in FIGS. 1 and 2, and duplicate explanations are omitted.

[0059] As shown in FIG. 9, when the digital key service server 40 determines that the ambulance 50 has arrived within the predetermined range 70 from the house 10 based on, for example, the position information of the ambulance 50 acquired from the emergency service server 20, the digital key service server 40 may transmit a mode change signal to the portable information terminal 30 ( "(5b) Mode change signal"). When receiving the mode change signal from the digital key service server 40, the portable information terminal 30 transmits the mode change signal to the unlocking device 100 ( "(6b) Mode change signal"). In the illustrated embodiment, the mode change signal is transmitted to the portable information terminal 30. However, the present disclosure is not limited thereto. For example, the mode change signal may be transmitted to the unlocking device 100 via the Internet.

[0060] Furthermore, the digital key service server 40 transmits an emergency password to the portable information terminal of the emergency team member 80 ( "(7b) Emergency password"). When acquiring the emergency password, the emergency team member 80 inputs the emergency password transmitted to the portable information terminal 30 into the front door 60 or the unlocking device 100 ( "(8b) Emergency password"). Specifically, the emergency team member 80 may manually input the emergency password into the input device of the front door 60, or may transmit a wireless signal indicating the emergency password to the unlocking device 100. When shifting to the emergency mode, the unlocking control unit 120 unlocks the front door 60 in response to the input password matching the emergency password.

[0061] FIG. 10 is a sequence diagram showing digital key control processing according to another embodiment of the present disclosure. In the embodiment shown in FIG. 10, steps S301 to S306 in FIG. 10 are the same as steps S101 to S106 in FIG. 7, and redundant explanations are omitted.

[0062] In step S307, the digital key service server 40 transmits a mode change signal to the portable information terminal 30.

[0063] In step S308, the portable information terminal 30 transmits the mode change signal to the unlocking device 100 to change the unlocking device 100 from the normal mode to the emergency mode.

[0064] In step S309, the digital key service server 40 transmits the emergency password to the portable information terminal of the emergency responder 80.

[0065] In step S310, the emergency responder 80 inputs the emergency password into the front door 60 or the locking / unlocking device 100 to unlock the front door 60.

[0066] Note that the embodiments shown in FIGS. 9 and 10 may be used alone or in combination with the embodiments shown in FIGS. 1 and 2. Further, the processing related to the portable information terminal 30 described above can be realized by the processor 34 executing an application program installed in the portable information terminal 30.

[0067] FIG. 11 is a schematic diagram showing digital key control processing according to another embodiment of the present disclosure. In this embodiment, in the case where the portable information terminal 30 that has transmitted an emergency notification, such as in the event of a disaster such as a fire, cannot remotely control the locking / unlocking device 100, when the digital key service server 40 responds to a notification from the emergency service server 20 and the fire truck 51 approaches the house 10, the digital key service server 40 transmits a mode change signal to the emergency mode to the locking / unlocking device 100 and transmits an unlocking signal for forcibly unlocking the front door 60 to the locking / unlocking device 100. In the embodiment shown in FIG. 11, "(1) Emergency notification", "(2) Dispatch order", "(3) Location information", and "(4) Emergency cooperation" are the same as those in the embodiments shown in FIGS. 1 and 2, and duplicate explanations are omitted.

[0068] As shown in FIG. 11, when the digital key service server 40 determines that the fire truck 51 has arrived within a predetermined range 70 from the house 10 based on the position information of the fire truck 51 acquired from, for example, the emergency service server 20, the digital key service server 40 transmits a mode change signal for changing to the emergency mode to the unlocking device 100 ( "(5b) Mode change signal"). When receiving the mode change signal from the digital key service server 40, the unlocking device 100 changes to the emergency mode. When shifting to the emergency mode, the unlocking device 100 waits to receive an emergency unlocking signal for forcibly unlocking the front door 60, for example.

[0069] Then, when receiving the emergency unlocking signal from the digital key service server 40 ( "(7b) Emergency unlocking signal"), the unlocking device 100 unlocks the front door 60 in response to the received signal matching the emergency unlocking signal.

[0070] FIG. 12 is a schematic diagram showing a digital key control process according to another embodiment of the present disclosure. In this embodiment, in the case where the mobile information terminal 30 that has transmitted an emergency notification, such as during a disaster such as a fire, cannot remotely control the unlocking device 100, the digital key service server 40 responds to the notification from the emergency service server 20 and when the fire truck 51 approaches the house 10, the digital key service server 40 transmits a mode change signal to the emergency mode to the unlocking device 100 and transmits an emergency password for forcibly unlocking the front door 60 to the firefighter 81. In the embodiment shown in FIG. 12, "(1) Emergency notification", "(2) Dispatch order", "(3) Position information", and "(4) Emergency cooperation" are the same as those in the embodiments shown in FIGS. 1 and 2, and duplicate explanations are omitted.

[0071] As shown in FIG. 12, when the digital key service server 40 determines that the fire truck 51 has arrived within the predetermined range 70 from the house 10 based on the position information of the fire truck 51 acquired from, for example, the emergency service server 20, the digital key service server 40 transmits a mode change signal for changing to the emergency mode to the unlocking device 100 ( "(5b) Mode change signal"). When receiving the mode change signal from the digital key service server 40, the unlocking device 100 changes to the emergency mode. When shifting to the emergency mode, the unlocking device 100 waits, for example, for the reception of an emergency password for forcibly unlocking the front door 60.

[0072] Furthermore, the digital key service server 40 transmits the emergency password to the firefighter 81 ( "(7b) Emergency password"). Then, when receiving the emergency password from the firefighter 81 ( "(8b) Emergency password"), the unlocking device 100 unlocks the front door 60 in response to the input password matching the emergency password.

[0073] In the above-described embodiment, the unlocking device 100 is remotely unlocked by an unlocking signal. However, the digital key control process according to the present disclosure is not limited to this, and the unlocking device 100 may be unlocked by the firefighter 80 inputting the emergency password transmitted from the digital key service server 40 to the front door 60.

[0074] In the above-described embodiment, the resident's portable information terminal 30 or the monitoring system made an emergency call. However, in the case of an accident, disaster, fire, etc., there may be a case where it is difficult for the resident or the monitoring system to make an emergency call. In this case, the discoverer of an accident, disaster, fire, etc. in the house 10 may make an emergency call. In this case, the unlocking device 100 may be remotely unlocked using the emergency password described above with reference to FIGS. 9 and 10. Alternatively, the portable information terminal 30 may shift the unlocking device 100 from the normal mode to the emergency mode and transmit an unlocking signal to the unlocking device 100 by the approach of an emergency vehicle. At this time, it may be confirmed or the transition to the emergency mode may be made by email or SMS to a preset malfunction prevention contact destination.

[0075] As described above, the embodiments of the present disclosure have been described in detail. However, the present disclosure is not limited to the specific embodiments described above, and various modifications and changes are possible within the scope of the gist of the present disclosure described in the claims.
