[0014] In order to more clearly describe the technical solutions in the embodiments of the present invention, the drawings that need to be used in the description of the embodiments are briefly described below. It should be noted that the drawings in the following description are only preferred embodiments of the present invention, and it is obvious that a person skilled in the art can further obtain other drawings based on the drawings without any creative efforts.

[0015] [Figure 1] 1 is a schematic diagram of the overall process of a digital signature method based on digital real-name authentication according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0016] The principles and features of the present invention will be explained below with reference to the drawings, and the examples listed are merely for the purpose of illustrating the present invention and are not intended to limit the scope of the present invention.

[0017] Referring to Figure 1, the present invention provides a digital signature method based on digital real-name authentication, which is applied to a digital signature system based on digital real-name authentication. The system includes a client module, a digital real-name authentication module, a digital signature module, a service module and an authorization module, and the method includes: Step S1, in which a client requests a digital signature from a digital signature module via a client module; Step S2: the digital real-name authentication module performs real-name authentication on the client that has requested the digital signature; Step S3: When the client passes the real-name authentication by the digital real-name authentication module, a service function of the service module is triggered; Step S4: when the client selects a service function through the service module, the authorization module performs authorization for the service function selected by the client; Step S5 includes a step in which, when the authorization module completes authorization for the service function selected by the client, the digital signature module digitally signs the service function selected by the client.

[0018] For example, when a client wishes to make a digital signature, the client module can request a digital signature. The client module is specifically designed to meet the digital signature requirements of clients in different regions, thereby improving the efficiency of signing. To ensure the authenticity of the client, the digital real-name authentication module can perform real-name authentication on the client, thereby ensuring the security of the signature. Through real-name authentication, the client can select service functions that meet their needs, thereby satisfying the diverse needs of the client. The authorization module issues authorization to the client who has completed the service function selection. After authorization is completed, the client can obtain a digital signature, which is advantageous for integrating online and offline processes, facilitating remote work, and improving work efficiency.

[0019] In step S2, the digital real-name authentication module performs real-name authentication on the client that has requested the digital signature, further comprising: Step S21: the digital real-name authentication module obtains client data by calling a third-party API interface; Step S22 includes a step in which the digital real-name authentication module compares the client who requested the digital signature with the acquired client data, and if the comparison is successful, completes real-name authentication for the client who requested the digital signature.

[0020] For example, the third-party API interface may be data published by the State Administration for Industry and Commerce's client information system or the Public Security Bureau's client identification system, and the data published by the State Administration for Industry and Commerce's client information system or the Public Security Bureau's client identification system can ensure the authenticity of the client.

[0021] In step S3, the service function of the service module triggered when the client passes the real-name authentication by the digital real-name authentication module is specifically: When a client passes real-name authentication by the digital real-name authentication module, the digital real-name authentication module obtains the client's IP address and uploads the IP address to the blockchain and stores it. The service functions of the service module specifically include business form calling, cost consulting, device management, report printing, and file storage.

[0022] For example, in order to guarantee the interests of a client, when the client passes real-name authentication using a digital real-name authentication module, the digital real-name authentication module obtains the IP address of the client, and stores the IP address in an up-chain manner on the blockchain. The client's IP address is then stored in an up-chain manner on the blockchain, thereby enabling traceability of the client and avoiding conflicts of interest.

[0023] In step S4, the client selects a service function through the service module, and the authorization module performs authorization for the service function selected by the client, specifically, Step S41: When the client selects one of the service functions such as business form calling, cost consulting, device management, report printing, and file storage, the approval module approves the service function selected by the client; Step S42, when the authorization module completes authorization for the service function selected by the client, an authorization log of the authorization is generated; Step S43: The approval module up-chains and stores the approval log in the blockchain.

[0024] For example, to improve client efficiency, service functions such as calling up business forms, cost consulting, device management, report printing, and file storage can be handled as online services, thereby avoiding the situations that arise in the process of using traditional seals, which involve many layers, cross-departmental collaboration, and collaboration between multiple people, making the process complicated and lengthening the stamping cycle, resulting in low efficiency. Furthermore, since an approval log is generated each time approval is made, the approval log can be further uploaded and stored on the blockchain, thereby ensuring the traceability of approval.

[0025] When the authorization module completes authorization for the service function selected by the client, the digital signature module digitally signs the service function selected by the client in step S5, further comprising: Step S51: when the authorization module completes authorization for the service function selected by the client, the digital signature module calls the authorization log and generates a seal service interface; Step S52: generating a template seal through a seal service interface, generating an image seal, and setting a default seal; Step S53 includes the step of: the digital signature module digitally signing the service function selected by the client according to the generation of the template seal, the generation of the image seal and the setting of the default seal.

[0026] For example, the digital signature module can generate a seal service interface only after obtaining an authorization log, and further generate a template seal, generate an image seal, and set a default seal. The generation of the template seal, the generation of the image seal, and the setting of the default seal can meet the various digital signature needs of clients, thereby improving the efficiency of digital signature.

[0027] Another embodiment of the present invention provides a digital signature system based on digital real-name authentication, which performs the method provided in the above embodiment, and includes a client module, a digital real-name authentication module, a digital signature module, a service module, and an authorization module.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, substitutions, improvements, etc. made within the spirit and scope of the present invention should be included within the protection scope of the present invention.
