[0025] Figure 1 Schematic diagram of the digital door lock authentication and unlocking system according to an embodiment of the present invention. Figure 2 is a schematic diagram of a digital key 110 according to an embodiment of the present invention.
[0026] The digital door lock authentication and unlocking system 100 of the embodiment of the present invention includes a digital key 110, a digital door lock 130 and a remote authentication server 150. The digital key 110 mainly includes a biometric identification component 111, a charging port 112, a positioning point 113 and metal contact points 114, 115 and 116.
[0027] The biometric identification component 111 is used to activate the digital key 110 and identify the user, wherein the biometric identification can be fingerprint identification, iris identification, facial recognition and other technologies. The charging port 112 is used to charge the digital key 110. In addition to the contact charging method, wireless charging can also be used. The positioning point 113 is used to confirm that the digital key 110 has been fully inserted into the digital door lock 130. When the digital key 110 is inserted into the digital door lock 130, the protruding positioning point 113 will trigger the mechanism in the digital door lock 130, and the user can then turn the digital key 110.
[0028] Metal contact point 114 is ground (GND), and metal contact point 115 represents power (Current Condenser, VCC). Metal contact points 114 and 115 are mainly used to power charging port 112. Metal contact point 116 is used to transmit data between digital key 110 and digital door lock 130. Digital key 110 also provides a slot for inserting a Subscriber Identity Module (SIM) card to provide mobile network access capability.
[0029] Figure 3 1 is a schematic diagram of inserting a digital key 110 into a digital door lock 130 according to an embodiment of the present invention.
[0030] The digital door lock 130 has a row of metal springs on the inner side, which are mainly used to obtain power and data transmission. When the digital key 110 is inserted into the digital door lock 130, it must be rotated to contact the metal springs. The digital door lock 130 has a snap-on button inside. When the digital key 110 is fully inserted into the digital door lock 130, the positioning point 113 will press the snap-on button, and the digital key 110 can then be rotated.
[0031] refer to Figure 1 The functions of the remote authentication server 150 include storing binding data and unlocking authentication.
[0032] Before using the digital key 110, it must be bound to the digital door lock 130. In addition to storing one copy of the binding data in the digital key 110 and the digital door lock 130, another copy is stored in the remote authentication server 150.
[0033] In the embodiment of the present invention, one digital key can only be bound to one digital door lock, while one digital door lock can be bound to multiple digital keys.
[0034] When the digital key 110 is bound to the digital door lock 130 and the digital key 110 is inserted and the digital door lock 130 is started, the digital door lock 130 starts to interact with the remote authentication server 150 and can be opened when it is confirmed that the digital key 110 has obtained the authority.
[0035] Figure 4 This is a flowchart of the steps of the authentication and unlocking method of the digital door lock of the embodiment of the present invention, which is applied to the microcontroller of the electronic device. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.
[0036] Step S101, performing a device binding operation. Before use, the digital key 110 and the digital door lock 130 need to be bound, and the device binding operation only needs to be completed at the very beginning of use.
[0037] Step S102, unlocking the digital key 110. The user must activate the digital key 110 through biometric identification, and the digital key 110 can be activated and used only when the identification is successful.
[0038] The user unlocks the digital key 110 by biometric identification. The biometric identification technology can be any of the following: fingerprint identification, iris identification, face identification, and voiceprint identification. In addition to biometric identification, a password can also be used to unlock the key. After unlocking, the digital key 110 enters the unlocking mode.
[0039] In step S103 , the digital key 110 is inserted into the digital door lock 130 to start the digital door lock 130 . The user inserts the digital key 110 into the digital door lock 130 , confirms the positioning, turns the digital key 110 , and starts the digital door lock 130 .
[0040] Step S104, determine whether it has been bound. After the digital door lock 130 is started, it will confirm whether the inserted digital key 110 is a bound device. If the digital key 110 is not a bound device, the method process ends.
[0041] Step S105 , if the digital key 110 is a bound device, a network link is established between the digital door lock 130 and the digital key 110 .
[0042] Step S106, determining whether the digital door lock 130 has passed the authentication of the remote authentication server 150. After the digital door lock 130 and the digital key 110 establish a network link, the digital door lock 130 performs authentication with the remote authentication server 150. If the authentication fails, the method process ends.
[0043] Step S107, if the authentication is successful, the digital door lock 130 unlocks. When the digital door lock 130 passes the authentication of the remote authentication server 150, the remote authentication server 150 notifies the digital door lock 130 to unlock.
[0044] Figure 5This is a flowchart of the steps of device binding in an embodiment of the present invention, which is applied to a microcontroller of an electronic device. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.
[0045] Step S201 , long press a start button (not shown) of the digital key 110 for a fixed time, for example, 10 seconds, so that the digital key 110 enters a binding mode.
[0046] Step S202 , inserting the digital key 110 into the digital door lock 130 to activate the digital door lock 130 .
[0047] In step S203, the digital door lock 130 determines whether the digital key 110 is an approved device. The digital door lock 130D determines whether the digital key 110 is an approved device based on the hardware identifier (first hardware identifier) of the digital key 110, for example, whether the digital key 110 is from the same manufacturer. If the digital key 110 is not an approved device, the method process ends.
[0048] In step S204 , if the digital key 110 is an approved device, the digital door lock 130 replies with its hardware identifier (second hardware identifier) to the digital key 110 , and a network link is established between them.
[0049] Step S205, after establishing the network link, the digital door lock 130 transmits binding data to the remote authentication server 150 to complete the binding. The binding data includes the first hardware identifier and the second hardware identifier. After receiving the binding data, the remote authentication server 150 responds with a binding code to the digital door lock 130. The digital door lock 130 stores the binding code and transmits the binding code to the digital key 110, and then ends the process of this method.

The processor 210 is generally used to control the overall operation of the electronic device 200. In this embodiment, the processor 210 is used to run the program code stored in the memory 220 or process data, for example, to run the authentication and unlocking system 230 of the digital door lock.
[0053] It should be noted that Figure 6 The electronic device 200 is merely illustrated as an example. In other embodiments, the electronic device 200 may also include more or fewer components, or have a different component configuration.
[0054] If the module / unit integrated in the electronic device 200 is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the present invention implements all or part of the processes in the above-mentioned embodiment method, and can also be completed by instructing the relevant hardware through a computer program. The computer program can be stored in a computer-readable storage medium. When the computer program is executed by the processor, the steps of the above-mentioned various method embodiments can be implemented. Among them, the computer program includes computer program code, and the computer program code can be in source code form, object code form, executable file or some intermediate form. The computer-readable medium may include: any entity or device that can carry the computer program code, recording medium, U disk, mobile hard disk, disk, optical disk, computer memory, read-only memory, random access memory, electric carrier signal, telecommunication signal and software distribution medium. It should be noted that the content contained in the computer-readable medium can be appropriately increased or decreased according to the requirements of legislation and patent practice in the jurisdiction. For example, in some jurisdictions, according to legislation and patent practice, computer-readable media do not include electric carrier signals and telecommunication signals.
[0055] Figure 7 2 is a functional block diagram of an electronic device according to an embodiment of the present invention, which is used to execute the authentication and unlocking method and system of a digital door lock. The authentication and unlocking method and system of a digital door lock according to an embodiment of the present invention can be implemented by a computer program in a storage medium, for example, a memory 220 in an electronic device 200. When the computer program implementing the method of the present invention is loaded into the memory 220 by the processor 210, the processor 210 of the device 200 is driven to execute the authentication and unlocking method and system of a digital door lock according to an embodiment of the present invention.
[0056] The electronic device 200 of the embodiment of the present invention includes a binding module 310 , a detection and activation module 320 , and an unlocking module 330 .
[0057] The binding module 310 performs a device binding operation to bind the digital key 110 to the digital door lock 130 .
[0058] The detection and activation module 320 activates the digital door lock 130 when the digital key 110 is detected to be inserted into the digital door lock 130. It should be noted that before the digital key 110 is inserted into the digital door lock 130, the user must first activate the digital key 110 through biometric identification, and it can be activated and used only when the identification is successful. The user unlocks the digital key 110 through biometric identification, and the biometric identification technology can be any of the following: fingerprint recognition, iris recognition, face recognition and voiceprint recognition. In addition to biometric identification, a password can also be used to unlock. After unlocking, the digital key 110 enters the unlocking mode.
[0059] The detection and activation module 320 determines whether the digital key 110 is a bound device, and if the digital key 110 is a bound device, establishes a network link between the digital door lock 130 and the digital key 110 .
[0060] The unlocking module 330 determines whether the digital door lock 130 has passed the authentication of the remote authentication server 150. After the digital door lock 130 and the digital key 110 establish a network link, the digital door lock 130 and the remote authentication server 150 perform authentication.
[0061] If the authentication is successful, the unlocking module 330 performs an unlocking operation on the digital door lock 130. When the digital door lock 130 passes the authentication of the remote authentication server 150, the remote authentication server 150 notifies the digital door lock 130 to unlock.
