[0043] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this application will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in the specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0045] The embodiment of the present application provides a blockchain-based electronic access control management method and corresponding solution, which generates access certificates such as QR codes or dynamic passwords based on blockchain technology, or realizes access certificates based on face recognition technology, ensuring data security and traceability; through blockchain technology, users receive, view, and authorize access codes, community face recognition information, community personal basic information and other operations are encrypted and chained, making the data safe and reliable and cannot be tampered with; close to the actual user usage scenario, a variety of authorization verification mechanisms are provided, mainly divided into three methods: face recognition door opening, dynamic QR code door opening, and dynamic password door opening, which can well cover the existing community access control usage scenarios. The mechanism is ingeniously designed, with excellent data security, broad market prospects, and strong replicability.

[0046] Figure 1 The method flow chart provided in the embodiment of this specification is as follows. As shown in the figure, the method includes:

[0047] S101 receives a user's access certificate through a sensor of a door access control system, wherein the access certificate includes at least one of the following: a QR code, a dynamic password, and biometric information;

[0048] S102 The smart contract of the blockchain determines whether the user's access certificate can open the door based on the association between the user's access certificate and the information in the blockchain.

[0049] It can be understood that the association relationship indicates whether the information is directly the same or indirectly the same.

[0050] If the user has the authority to open the access control, the verification is successful, and the blockchain sends the verification information to the access control, then the access control is opened and the person enters.

[0051] Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and a distributed ledger that is cryptographically guaranteed to be tamper-proof and unforgeable. Although the underlying technology of blockchain has been developed for many years, it cannot be effectively applied in specific scenarios.

[0052] According to a specific embodiment of the present invention, a smart contract for managing user information is set on the blockchain. The smart contract is an automated script deployed on the blockchain. Since it is set on the blockchain, it has the characteristics of openness and transparency. Users pre-set rules through smart contracts to write data into the blockchain and obtain data browsing permissions, which largely avoids the disclosure of private information. Of course, smart contracts are not the only implementation method of this application, and are set accordingly according to different blockchain platforms, such as Ethereum, Hyperledger, etc.

[0053] Before the verification step, the system must be debugged and user data must be saved to facilitate information matching by the blockchain-based access control system. The general process is as follows:

[0054] Receive proof information submitted by the user, the proof information includes but is not limited to: facial information, property certificate name, lease contract, work certificate. It can be understood that the embodiment of the present invention only discloses the proof information corresponding to residential areas and workplaces commonly used in production activities. The proof information should be set according to different locations, and it can also be some other special scenes, such as hospitals and schools, etc., which will not be elaborated here.

[0055] The proof information is sent to the designated node in the blockchain for confirmation to determine whether to write the proof information into the blockchain. Depending on the scenario, the node can be a property management company, a housing rental agency, a neighborhood committee, or a company's human resources agency. For example, in a commercial office building, there is a property management company and several other commercial companies. The blockchain is built from the relevant equipment in these companies. When performing authentication, the employee information of each company can be submitted to the adjacent company or property management for authentication.

[0056] Once the proof information is authenticated, the data can be written into the blockchain, and based on the information stored in the blockchain, the user can be provided with access control proof and verification services.

[0057] According to a specific embodiment of the present invention, in step S101, the user's entry and exit proof is received by the sensor on the access control system. There may be multiple types of entry and exit proofs, which are determined by the hardware equipment installed in each residential area or commercial office area. For example, if there is an image sensor with a face recognition function, the face information can be directly obtained through the image sensor and the face information can be used as the entry and exit proof; if it is a button type or a QR code scanner, the user is required to obtain the entry and exit proof, a dynamic password or a dynamic QR code from the blockchain.

[0058] In some preferred embodiments of the present invention, the embodiments of the present invention also provide a method for providing access certificates for temporary outsiders based on the encryption algorithm of the blockchain. In some embodiments of the present invention, such access certificates provided for temporary outsiders are called temporary access certificates. The first user represents an outsider, and the second user represents an internal person. For example, the first user represents a customer who temporarily visits the enterprise, and the second user represents an employee of the enterprise. The general process is as follows:

[0059] The smart contract of the blockchain receives a visit reservation of a first user, and endorses the first user through a second user involved in the visit reservation;

[0060] The smart contract of the blockchain generates a temporary access certificate for the first user based on the endorsement of the second user, so that the first user has the authority to open the door within a specified time, wherein the temporary access certificate is one of the access certificates.

[0061] In particular, the embodiment of the present invention implements the above management process through an asymmetric encryption algorithm. The specific process is as follows:

[0062] Encrypting the identity information of the first user by using the private key of the second user to form an electronic signature;

[0063] Generate a temporary access certificate for the first user through the electronic signature, the identity information of the first user and the visit appointment;

[0064] After the user presents the temporary access certificate to the access control sensor, the sensor sends the temporary access certificate to the backend (blockchain) for verification;

[0065] Determine the authenticity of the temporary access certificate by using the electronic signature in the temporary access certificate and the public key of the second user;

[0066] Determine the validity of the temporary access certificate based on the visit appointment and current time in the temporary access certificate;

[0067] Whether the temporary access certificate of the second user can open the door is determined by the authenticity and validity of the temporary access certificate.

[0068] It should be noted that when the temporary access certificate of the first user is received through the access control sensor, the electronic signature and visit appointment in the temporary access certificate are written into the blockchain.

[0069] The embodiment of the present invention realizes information confirmation and information tracing of the endorser through electronic signature, which is convenient and safe.

[0070] Based on the same idea, some embodiments of the present application also provide devices and non-volatile computer storage media corresponding to the above methods.
