[0042] Figure 2 The flowchart of a blockchain-based electronic signature method provided in the embodiment of the present application. The process can be executed by a blockchain-based electronic signature device to achieve the reliability, non-tamperability and traceability of the electronic signature. Figure 2 As shown, the process includes the following steps:

[0043] 201: Receive an electronic signature application request from a target object, where the electronic signature application request carries application information and identification information of the target object.

[0044] In some embodiments, before receiving the electronic signature application request of the target object, the terminal (such as Figure 1 The user interface of the terminal 10 shown in the figure registers the account for logging into the client (which may be the account ID assigned by the client, or the user's mobile phone number, etc.) so that the client can be quickly logged into later.

[0045] In some embodiments, receiving the electronic signature application request of the target object may be: in response to a user operation of filling in the electronic signature application related to the user interface, receiving the electronic signature application request of the target object. It should be noted that the user operation may be a user operation in the form of a voice assistant or a manual user operation, which is not limited in this embodiment of the present application.

[0046] In some embodiments, if the target object is a user, the identification information may include the user's name, ID number, etc.; if the target object is an enterprise, the identification information may include the enterprise's name, enterprise tax number, etc.

[0047] 202: If the target object is verified to be legitimate based on the identification information, an electronic signature of the target object is generated based on the identity and application information of the target object, and the signature information of the electronic signature is stored in the blockchain.

[0048] In some embodiments, a server (such as Figure 1The server 11) shown can determine whether the target object is legal by connecting to the database of a department and verifying whether the identification information is consistent with the identification information contained in the database; if the target object is verified to be legal based on the identification information, it indicates that the identity of the target object is valid and authentic, and the subsequent process can be carried out; if the target object is verified to be illegal based on the identification information, it indicates that the identity of the target object is invalid and false, and a pop-up window can be displayed to confirm whether the relevant information filled in is accurate, which is convenient for the applicant to take corresponding measures and also improves the security of the electronic signature operation.

[0049] In other embodiments, if the target object is a user, technical means such as real-name authentication and face recognition may be used to ensure the legitimacy of the target object.

[0050] In some embodiments, based on the identity of the target object and the application information, an electronic signature of the target object is generated, and the signature information of the electronic signature is stored in the blockchain, which may include the following situations:

[0051] Case 1: If the identity of the target object is a user identity, in response to the authorized object with authorization management authority confirming that the electronic signature application request is qualified on the user interface, a user electronic signature of the target object is generated based on at least the user information of the target object in the application information (such as the user's name, ID number, ID type, etc.), and the signature information of the user electronic signature is stored in the blockchain.

[0052] Furthermore, the signature information of the user's electronic signature is stored in the blockchain, which can be: at least the signature identification, signature image, creation information, signature version number, signature type, authorization information of the authorized object, and user information of the target object of the user's electronic signature are stored in the blockchain, as shown in Table 1, which exemplifies an example table of signature information of the user's electronic signature.

[0053] Table 1: User electronic signature information example table

[0054]

[0055]

[0056] Case 2: If the identity of the target object is a corporate identity, then based on at least the corporate information of the target object in the application information (such as corporate name, corporate tax number, etc.), the corporate electronic signature of the target object is generated, and the signature information of the corporate electronic signature is stored in the blockchain.

[0057] Furthermore, the signature information of the enterprise electronic signature is stored in the blockchain, which can be: at least the signature logo, signature image, creation information, signature version number, signature type, and corporate information of the target object of the enterprise electronic signature are stored in the blockchain, as shown in Table 2, which exemplifies an example table of signature information of the enterprise electronic signature.

[0059]

[0060]

[0061] It should be noted that the contents contained in Table 1 and Table 2 are merely examples. In actual scenarios, other relevant signature information may also be included. The embodiments of the present application do not specifically limit the contents contained in the signature information.

[0062] In this step, when individuals or companies apply for electronic signatures, their relevant signature information will be stored in the blockchain, and various types of electronic signatures will be managed in a distributed manner, making the application process of electronic signatures reliable and non-repudiable, and making the generated electronic signatures secure and provable.

[0063] In other embodiments, the method further includes: receiving a signature information update request for an electronic signature; updating the electronic signature based on the new signature information carried in the signature information update request, and updating the signature information in the blockchain based on the new signature information, so as to achieve information synchronization and facilitate the traceability of the electronic signature. Furthermore, the new signature information may be a change in the signature type of the electronic signature, or a change in the corporate information or user information associated with the electronic signature, or a deletion of the electronic signature, etc.

[0064] In other embodiments, the method further includes: in response to the execution of the contract signing operation based on the electronic signature, the signed contract information is associated with the electronic signature and stored in the blockchain to form a persistent and unalterable signing record. For example, when signing a contract, the relevant parties use their respective electronic signatures, together with the contract and the location of the signature and seal, to call the blockchain-based electronic signature device on the server to sign and seal. At the same time, the electronic signature and the contract information of the relevant contract are written into the blockchain together, thereby forming a persistent and unalterable signing record, which can be traced at any time in the future.

[0065] In an embodiment of the present application, an electronic signature application request is received from a target object, and the electronic signature application request carries the application information and identification information of the target object; if the target object is verified to be legal based on the identification information, an electronic signature of the target object is generated based on the identity and application information of the target object, and the signature information of the electronic signature is stored in the blockchain. The technical characteristics of the blockchain are utilized to realize the management of the entire electronic signature process, thereby solving the tampering, security and non-traceability problems existing in the electronic signature management process in related technologies.

[0066] Based on the above Figure 2 The process shown, Figure 3 A flowchart of a complete blockchain-based electronic signature method provided in an embodiment of the present application.

[0067] 301: After the user enters the account number to log in to the signature system, he fills in the application information and identification information related to the target object on the user interface and submits the electronic signature application request.

[0068] 302: After receiving the electronic signature application request, verify whether the target object is legal based on the identification information. If yes, proceed to 303; if not, a pop-up window prompts.

[0069] In other embodiments, after the verification is passed, it is possible to further check whether the target object has applied for an electronic signature. If so, the relevant creator is prompted that he cannot apply again; if not, proceed to the next step.

[0070] 303: Determine whether the target object is a user or an enterprise based on the identity of the target object. If the identity of the target object is a user, proceed to 304; if the identity of the target object is an enterprise, proceed to 305.

[0071] 304: The electronic signature application request is sent to an authorized object with authorization management authority for review. If the electronic signature application request is confirmed to be qualified, a user electronic signature of the target object is generated based on at least the user information of the target object in the application information, and the signature information of the user electronic signature is stored in the blockchain.

[0072] 305: Generate an enterprise electronic signature of the target object based at least on the enterprise information of the target object in the application information, and store the signature information of the enterprise electronic signature in the blockchain.
