[0028] According to one aspect of an embodiment of the present application, an information update method is provided. The information update method is widely used in smart home (Smart Home), smart home, smart home device ecology, smart residential (IntelligenceHouse) ecology and other whole-house intelligent digital control application scenarios. Optionally, in this embodiment, the above information update method can be applied to Figure 1 In the hardware environment composed of the terminal device 102 and the server 104 shown in FIG. Figure 1 As shown, the server 104 is connected to the terminal device 102 via a network, and can be used to provide services (such as application services, etc.) for the terminal or a client installed on the terminal. A database can be set on the server or independently of the server to provide data storage services for the server 104. Cloud computing and / or edge computing services can be configured on the server or independently of the server to provide data computing services for the server 104.

[0029] The network may include but is not limited to at least one of the following: wired network, wireless network. The wired network may include but is not limited to at least one of the following: wide area network, metropolitan area network, local area network, and the wireless network may include but is not limited to at least one of the following: WIFI (Wireless Fidelity), Bluetooth. The terminal device 102 may be but is not limited to a PC, a mobile phone, a tablet computer, a smart air conditioner, a smart range hood, a smart refrigerator, a smart oven, a smart stove, a smart washing machine, a smart water heater, a smart washing device, a smart dishwasher, a smart projection device, a smart TV, a smart clothes drying rack, a smart curtain, a smart audio and video, a smart socket, a smart speaker, a smart fresh air device, a smart kitchen and bathroom device, a smart bathroom device, a smart sweeping robot, a smart window cleaning robot, a smart mopping robot, a smart air purification device, a smart steamer, a smart microwave oven, a smart kitchen treasure, a smart purifier, a smart water dispenser, a smart door lock, etc.

[0030] In order to solve the above problems, an information updating method is provided in this embodiment, including but not limited to being applied in the whole house intelligent digital control application scenario. Figure 2 This is a flow chart of an information updating method according to an embodiment of the present application, the execution subject is a terminal device, and the process includes the following steps S202-S206:

[0031] Step S202: Sending a first request instruction to a cloud server, and obtaining a first key and a target random number sent by the cloud server in response to the first request instruction, wherein the first request instruction is used to request to add or delete biometric information in a target device, and the first key is a key generated by the cloud server using a first preset algorithm according to the target random number and device information of the target device;

[0032] Optionally, the biometric information includes, but is not limited to: the user's fingerprint information, facial information, iris information, voiceprint information, and palm vein information.

[0033] Optionally, the target device includes but is not limited to: a smart door lock.

[0034] Optionally, the cloud server combines the target random number and device information (such as device identifier (ID), device type, device serial number, etc.) as the basis for key generation, and uses a first preset algorithm to generate a unique first key bound to the device, wherein the first preset algorithm includes but is not limited to: hash algorithm, key derivation function based on hash algorithm, public key encryption algorithm.

[0035] It should be noted that the first preset algorithm can be a single algorithm or a combination of multiple algorithms.

[0036] Alternatively, if Figure 3 As shown, the user sends a first request instruction to the cloud server through the target application in the terminal device (for example, the target application in the mobile phone corresponding to the target device) to request to add biometric information (fingerprint, face, etc.) or delete biometric information; after receiving the request, the cloud server generates multiple random numbers, and randomly selects a random number from the multiple random numbers as the target random number, and uses the target random number and the specific device information of the target device to generate a first key using a first preset algorithm to ensure the uniqueness and security of the first key, wherein the target random number can increase the uncertainty and difficulty in the communication process to prevent the communication content from being predicted or replayed.

[0037] Step S204: Processing the acquired target biometric information based on the first key to obtain encrypted data, wherein the biometric information includes the target biometric information;

[0038] Step S206: Send a second request instruction to the target device, wherein the second request instruction carries: the encrypted data, the target random number and the first request instruction; the second request instruction is used to instruct the target device to use the first preset algorithm to generate a reference key according to the target random number and the device information of the target device, and obtain the target biometric information based on the reference key and the encrypted data, and add or delete the target biometric information in the biometric information list of the target device based on the first request instruction.

[0039] Alternatively, if Figure 3As shown, after obtaining the target biometric information, the target device verifies the format of the target biometric information to determine whether the format of the target biometric information is consistent with the data format in the biometric information list of the target device. When it is determined that the format of the target biometric information is consistent with the data format in the biometric information list of the target device, the target biometric information is added or deleted from the biometric information list of the target device based on the first request instruction.

[0040] It should be noted that the generation and use of the first key ensures that the encryption and decryption process of the target biometric information is only completed between three trusted endpoints (terminal application, cloud server and target device), avoiding data leakage in the middle; the introduction of target random numbers increases the uncertainty of the system and the difficulty of attack, and improves the security of communication; through the cloud server as an intermediary, the terminal device can remotely and securely manage the biometric information of the target device without the user of the terminal device having to go to the local location of the target device to perform operations in person, greatly improving the convenience and overall security of the system.

[0041] In the above steps, the target biometric information is processed by obtaining the first key generated by the cloud server to obtain encrypted data, the encrypted data is sent to the target device, and then the target device is instructed to obtain the target biometric information based on the reference key generated by the target device and the encrypted data, and the obtained target biometric information is added or deleted from the biological list of the target device. By combining the operation instructions with the biometric information encryption processing, the biometric information can be safely added or deleted between different devices, avoiding the biometric information only being entered on the target device, thereby solving the problem of strong limitations in the process of entering information in traditional smart door locks.

[0042] In an exemplary embodiment, the acquired target biometric information is processed based on the first key to obtain encrypted data, which can be achieved through the following steps: the target biometric information is encrypting using the first key to obtain the encrypted data; wherein the target device decrypts the encrypted data based on the reference key to obtain the target biometric information.

[0043] Optionally, the terminal device can use the first key to directly encrypt the acquired target biological information. When the target device obtains the second request instruction, it will use the first preset algorithm to generate a reference key based on the target random number carried by the second request instruction and the local device information of the target device (the same device information used by the cloud server to generate the first key). The reference key is consistent with the first key, so that the target device can decrypt the encrypted data according to the reference key to obtain the target biological information.

[0044] It should be noted that the first preset algorithm is an algorithm agreed upon by the cloud server and the target device in a pre-set phase, so the reference key generated by the target device using the first preset algorithm is consistent with the first key generated by the cloud server using the first preset algorithm.

[0045] Optionally, the terminal device uses the first key to encrypt the target biometric information, and the second request instruction sent to the target device does not carry the first key, thereby ensuring the information security during the transmission of the encrypted data. Even if the encrypted data is intercepted, the attacker cannot obtain the target biometric information without the corresponding first key for decryption, thereby significantly improving the security of remote data transmission.

[0046] In an exemplary embodiment, the acquired target biometric information is processed based on the first key to obtain encrypted data, which can be achieved by the following steps S11-S12:

[0047] Step S11: using a second preset algorithm to generate a second key based on the first key and account information of a target account, wherein the target account is the account that sends the first request instruction to the cloud server;

[0048] Optionally, the second preset algorithm includes, but is not limited to: a symmetric encryption algorithm (such as an Advanced Encryption Standard algorithm (AES for short)), a cryptographic hash function.

[0049] Alternatively, if Figure 3 As shown, the terminal device will, based on the first key, concatenate the account information of the target account (such as the user's identity identifier) ​​and use the second preset algorithm to obtain the second key.

[0050] Step S12: Use the second key to encrypt the target biometric information to obtain the encrypted data; wherein the second request instruction also carries the account information of the target account; the second request instruction is used to instruct the target device to use the second preset algorithm after generating the reference key, generate the second key according to the reference key and the account information of the target account, and use the second key to decrypt the encrypted data to obtain the target biometric information.

[0051] It should be noted that the use of the second key to encrypt the target biometric information is similar to adding an extra security layer to the target biometric information. Even if the first key is leaked, the attacker cannot generate the second key without the correct account information of the target account, which increases the difficulty for the attacker to decrypt the encrypted data.

[0052] Optionally, the second request instruction also carries the first key, such as Figure 3 As shown, after receiving the second request instruction, the target device first generates a reference key based on the target random number and the device information of the target device using the first preset algorithm, and verifies whether the reference key is consistent with the first key carried in the second request instruction. If they are consistent, the target device then uses the second preset algorithm to generate a second key based on the reference key and the account information of the target account, and finally uses the second key to decrypt the encrypted data to obtain the target biometric information.

[0053] It should be noted that through the generation and use of the second key, it is ensured that only users with correct account information can operate the smart door lock, thereby enhancing the authority control of remote management; the double encryption mechanism encrypts biometric information on the one hand and operation instructions on the other hand, ensuring the security of data and instructions; by verifying the consistency of the first key and the reference key, and using the second key for decryption, the accurate execution of the operation and the security of data transmission are ensured.

[0054] In an exemplary embodiment, after the acquired target biometric information is processed based on the first key to obtain encrypted data, the method further includes the following steps: when the terminal device and the target device have not established a communication connection, storing the second request instruction in a target storage area of ​​the terminal device, wherein the terminal device has a target application, a target account is logged in to the target application, the target application is an application corresponding to the target device, and the target account is an account that sends the first request instruction to the cloud server;

[0055] In an exemplary embodiment, sending the second request instruction to the target device includes the following steps: when the terminal device has established a communication connection with the target device, sending the second request instruction to the target device.

[0056] Alternatively, if Figure 3 As shown, the terminal device can locally store the encrypted target biometric information and related instructions (including the first key and target account information) without establishing a communication connection with the target device. Once the target device (smart door lock) and the terminal device (such as the user's mobile phone) re-establish a communication connection (for example, via Bluetooth or a local area network), the terminal device can send a second request instruction to the target device, requesting the execution of the corresponding biometric information management operation.

[0057] It should be noted that, through the above steps, the terminal device and the smart door lock can still save the first key and request instruction when no communication connection is established, thereby maintaining the availability and security of the remote information entry operation. Moreover, the above steps can also enable the terminal device to quickly synchronize and process biometric information data after restoring the communication connection with the target device even in a scenario where the communication capability is temporarily lost, thereby ensuring that the remote management of the smart door lock will not be affected by the instability of the network connection.

[0058] In an exemplary embodiment, after sending the second request instruction to the target device, the method further includes the following steps S21-S22:

[0059] Step S21: Acquire response information sent by the target device in response to the second request instruction;

[0060] Alternatively, if Figure 3 As shown, the target device will send a response message in response to the second request instruction, and the response message is used to indicate that the target device has successfully added the target biometric information to the biometric information list, or successfully deleted the target biometric information, or failed to add the target biometric information, or failed to delete the target biometric information.

[0061] It should be noted that the terminal device obtains the response information of the target device (smart door lock) in response to the second request instruction, and can confirm in real time whether the operation of adding or deleting biometric information is successfully executed. This provides a timely feedback mechanism for users and increases the transparency of operations.

[0062] Step S22: When the response information is used to indicate that the target device has successfully added the target biometric information or successfully deleted the target biometric information in the biometric information list, a recording instruction is sent to the cloud server, wherein the recording instruction is used to instruct the cloud server to record target operation information, wherein the target operation information includes: the target account has added the target biometric information or deleted the target biometric information in the target device, and the target account is the account that sent the first request instruction to the cloud server.

[0063] Optionally, when the response information is used to indicate that the target device fails to add the target biometric information to the biometric information list or fails to delete the target biometric information, the terminal device correspondingly deletes the target biometric information locally on the terminal device and sends a prompt information, wherein the prompt information is used to prompt the target device that the target device fails to add the target biometric information to the biometric information list or fails to delete the target biometric information, and to reacquire the target biometric information.

[0064] Optionally, after obtaining the response information, the terminal device will send a recording instruction to the cloud server within a preset time (eg, 48 hours).

[0065] It should be noted that by sending recording instructions to the cloud server, it helps ensure data consistency between the cloud server and the target device. The cloud server can record the specific information of each operation, including the initiating account (target account), target device, operation type (adding or deleting biometric information), and operation time. These records are important for tracking operation history, auditing security events, and restoring system status when necessary.

[0066] In an exemplary embodiment, obtaining the first key and target random number sent by the cloud server in response to the request instruction includes the following steps: obtaining the first key and target random number sent by the cloud server in response to the request instruction when the target account is verified, wherein the target account is the account that sends the first request instruction to the cloud server.

[0067] Alternatively, if Figure 3 As shown, before obtaining the first key and target random number sent by the cloud server in response to the request instruction, the terminal device will verify the authority of the target account through the account information of the target account (such as the account ID of the target account), to ensure that only the authorized target account can request to remotely add or delete the target biometric information on the target device. Only when the cloud server verifies the target account, the cloud server will send the first key and target random number, thereby increasing the security of the system.

[0068] Optionally, when the cloud server fails to verify the target account, a rejection prompt message will be sent, and the rejection prompt message is used to prompt that the target account currently logged in to the terminal device is not authorized.

[0069] It should be noted that the above steps enhance the encryption security of remote operations and improve the overall security of the system.

[0070] In an exemplary embodiment, before the acquired target biometric information is processed based on the first key to obtain encrypted data, the method further includes the following steps S31 or S32:

[0071] Step S31: collecting the target biometric information through a terminal device, wherein the terminal device has a target application, a target account is logged in to the target application, the target application is an application corresponding to the target device, and the target account is an account that sends the first request instruction to the cloud server;

[0072] Optionally, through step S31, the user installs and logs in to the target application on the terminal device (such as a smart phone), which is an official or supporting application of the target device (such as a smart door lock) and is used to manage the biometric information of the door lock. The terminal device directly participates in the biometric information collection process and provides the user with an intuitive operation interface. The terminal device is integrated with a biometric information collection module, such as a fingerprint sensor or a facial recognition camera, to capture the user's biometric data.

[0073] Step S32: Acquire the target biometric information sent by a specific account, wherein the specific account is an account corresponding to the target application.

[0074] Optionally, through step S32, other users can be allowed to send biometric information to a target account after the specific account has collected biometric information. The terminal device logged into the target account can send the target biometric information sent by the specific account to the target device. For example, in a scenario where family members share access rights to smart door locks, after one of them collects biometric information, the biometric information can be securely transmitted to the accounts of other family members, without the need for each member to log in to a specific account to collect biometric information. The method of sending biometric information through a specific account improves the convenience of updating or modifying biometric information.

[0075] Through the above two methods, not only a user-friendly biometric information collection and management process is provided, but also the security and privacy protection of biometric information is ensured, providing users with an efficient and safe remote operation experience.

[0076] In an exemplary embodiment, the method further includes the following steps: real-time monitoring of the record log of the cloud server, and sending an alarm message when the number of target operation information recorded in the record log exceeds a preset number within a preset time period, wherein the record log is used to store multiple target operation information recorded by the cloud server, and the alarm message is used to warn the target account of security risks.

[0077] Optionally, for example, within thirty minutes, the terminal device sends encrypted data including the target biometric information to the target device ten times, and each time the target device successfully adds the target biometric information, the cloud server records the success of this operation. If within the thirty minutes, the terminal device sends encrypted data to the target device for the eleventh time, the terminal device will send an alarm message.

[0078] Obviously, the above-described embodiments are only part of the embodiments of the present application, not all of the embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but it is not used to limit the technical solution of the embodiments of the present application. Optionally, when the terminal device is a mobile phone and the target device is a smart door lock:

[0079] When the user has bound a smart door lock (wireless network door lock or Bluetooth door lock) in the corresponding application on the mobile phone:

[0080] 1. Initiate editing request: The mobile application initiates user editing request, including adding, deleting, modifying and other operations;

[0081] 2. Information collection: If adding, modifying, etc., it is necessary to collect user information (fingerprint / face) through smart devices, and save the information according to the user's group editing, etc., and remove the user information if deleted;

[0082] 3. Data transmission: The edited information is encrypted and stored. If the mobile application has established communication with the smart door lock (remote / Bluetooth), the user decides whether to synchronize the data to the smart door lock immediately. If no communication is established, the user is prompted to synchronize the data to the smart door lock when the mobile application is connected to the smart door lock.

[0083] 4. Information storage and verification: After the smart door lock receives the fingerprint or face information, it will decrypt it and encrypt it again according to the rules for storage. During verification, the smart door lock processes the user information (face / fingerprint) attempting to unlock according to the rules and compares it with the stored information to decide whether to unlock the door.

[0084] Specifically, Figure 3 As shown:

[0085] 1. The application requests to add / edit a user, carrying information such as the user ID;

[0086] 2. The cloud server verifies the user's permissions based on the user ID;

[0087] 3. When the verification is passed, the cloud server generates a random number and confirms the target random number. According to the device factory information, the target random number, etc., it generates encryption key1 (the first key mentioned above);

[0088] 4. If the user does not have permission, return a rejection;

[0089] 5. If the user has permission, it returns permission and carries the target random number (random1) to encrypt key1;

[0090] 6. The application end encrypts key1, concatenates the user ID and other information, performs secondary encryption, and calculates the new encryption key2 (the above-mentioned second key);

[0091] 7. The application initiates the collection of user biometric information, assembles the data in a special format, and symmetrically encrypts the data using encryption key2;

[0092] 8. When no communication connection is established with the smart door lock, the user end saves the currently collected user information locally, including the target random number random1, encryption key1, encrypted data, etc.;

[0093] 9. The subsequent application establishes a communication connection with the smart door lock and starts to execute the subsequent steps;

[0094] 10. The application reads user information;

[0095] 11. The application transmits the encrypted data, target random number, and encrypted key1 to the device (smart door lock);

[0096] 12. The device generates and verifies the encryption key based on the target random number, factory information, etc. according to the cloud's pre-set encryption method;
