[0098] Figure 3 3 is a flow chart of an electronic signing method according to an exemplary embodiment. As shown in FIG. 3 , the method is used in a terminal. The method includes the following steps:

[0099] Step 201: Obtain the contract data sent by the user terminal, and obtain the legal contract data through the contract data, such as Figure 4 As shown, the specific process is as follows:

[0100] The contract data is verified through the IP blacklist to obtain the blacklist verified contract data. The system verification module verifies the allowed IP for each business request. For requests not in the whitelist, the request is directly intercepted. For each company and each business system, an independent account must be assigned, and each request needs to carry account information. Requests that do not meet the verification rules will be intercepted and not allowed to be called.

[0101] The blacklist verified signing data is verified by Token verification. The electronic signing service needs to apply for a token every time it calls the business. The same signing request needs to carry a token to prevent the system service from being called by the enterprise business request at will, resulting in additional digital certificate application fees and signature fees.

[0102] The logo-verified contract data is verified through account verification to obtain the account-verified contract data, the account-verified contract data is verified through parameter mandatory field verification to obtain the parameter mandatory field verification contract data, and the parameter mandatory field verification contract data is verified through legality to obtain the legal contract data.

[0103] Step 202: Obtain an electronic document template, such as Figure 5 As shown, the specific process is as follows:

[0104] The template of electronic documents can be made on the browser, and component-based saving and online testing are supported for the same style. The efficiency of template development will be greatly improved compared with the efficiency of generating electronic contracts using Word or Excel. It usually takes 8-16 hours to create a version, and it usually takes 2-4 hours to use template tools.

[0105] Implementation:

[0106] Electronic Template Design Tool

[0107] (1) Template design: multiple document components, dynamic format control, and reusable sub-template calls

[0108] (2) Template publishing and management: template publishing review and online testing, template version management, dynamic and personalized template call rule configuration

[0109] (3) Multi-channel formatting generation engine: Multi-document formatting generation and processing engine, supports multi-channel (paper, PDF, PDF Form, HTML / HTML5, OSD) delivery of the same template, supports dynamic clause insertion with formatting, and dynamic catalog generation.

[0110] Step 203, obtain electronic document data through the security contract data and the electronic document template, such as Figure 6 As shown, the specific process is as follows:

[0111] Obtaining the data format requirements for generating an electronic document, wherein the data format requirements for generating an electronic document include: PDF format and OSD format, and respectively parsing PDF and OSD file synthesis engines;

[0112] The electronic document data is obtained through the electronic document template, legal contract data and the format requirements for generating electronic document data. The electronic document data is an electronic file that is not stamped or digitally signed.

[0113] Step 204: Synthesize the electronic seal by parsing the parameters of the electronic seal request data, such as Figure 7 As shown, the specific process is as follows:

[0114] Receive the request data for obtaining the electronic seal;

[0115] The electronic seal request data determines the seal type through parameter parsing and seal loading, and the seal types include: text seal, saddle seal and position seal.

[0116] When the stamp type is text stamp, search for the corresponding stamp synthesis in this text;

[0117] When the stamp type is a saddle stamp, search for the corresponding business to synthesize the saddle stamp;

[0118] When the stamp type is position stamp, search for file position stamp synthesis.

[0119] Step 205: Acquire the electronic signature, obtain the signed document data through the electronic signature and the electronic document data, and send the signed document data to the imaging platform.

[0120] Determine the signature type through the electronic document data;

[0121] When the signature type is stamp, such as Figure 8 As shown, an electronic seal is obtained, and signed document data is obtained through the electronic document data and the electronic seal, which is used for paperless circulation vouchers for internal business. According to the transmitted seal number, the seal is affixed at the specified position of the electronic document. It supports stamping according to coordinates, text search, and the first and last positions of the file, and supports saddle stamping. The signed document data is sent to the imaging platform for permanent storage.

[0122] When the signature type is stamp and digital signature, such as Fig. 9 As shown, the electronic seal and the digital signature are obtained respectively, and the digital signature is obtained, including:

[0123] Receive the digital signature request data; determine the signature type through the digital signature request data, and the signature types include: manual digital signature and automatic digital signature; obtain the digital signature through the signature type. Integrate the user's handwritten signature image and the company seal into the electronic file, apply for the customer's digital certificate from the national authoritative digital certificate issuing agency, request the current time from the National Time Service Center, integrate the customer's digital certificate, the company's digital certificate, and the timestamp into the electronic file, and finally perform the signature calculation. The electronic signing service cooperates with the Supreme People's Court Judicial Blockchain Platform. After completing the signing on the electronic signing platform, the digital fingerprint of the electronic file will be uploaded to the judicial blockchain platform immediately. The calculation logic of the digital fingerprint is a public algorithm. When a legal dispute occurs later, the digital fingerprint of the electronic file provided by the enterprise can be calculated again and compared with the digital fingerprint on the judicial blockchain platform. It can prove that the document signed by the customer at that time is the original document provided by the enterprise, thereby improving the company's winning rate. Ensure the authenticity and non-tamperability of the electronic document signed by the customer, which is fully in line with the legal protection of electronic documents. The stamping location of the corporate seal supports stamping according to coordinates, text search, and the first and last positions of the document. It also supports the use of interline stamps to obtain signed document data through electronic document data, electronic seals, and digital signatures, and send the signed document data to the imaging platform.

[0124] Step 206: Store the signed document data and customer data in the server and provide services according to customer requests.

[0125] The services include: electronic file query, electronic file download, digital fingerprint query, customer digital certificate, seal management, accurate billing, online printing, enterprise digital certificate application, automatic renewal and information query.

[0126] Among them: Seal management is a backend service management service with the management, production and usage statistics of electronic seals. It can manage the electronic seals of all businesses using the electronic signing system and conduct online production and usage statistics, thereby solving the problem that the electronic signing platform in the industry can manage and produce electronic seals, but lacks relevant dimensions for usage statistics.

[0127] Accurate billing is a backend service management service with the billing capability for electronic signing digital certificates. It can conduct access statistics and bill inquiries according to different companies, different business systems, and different accounts without relying on third-party suppliers, thus solving the problem that traditional electronic signing platforms rely on third-party suppliers to understand billing situations. There is no intuitive statistical function for the company's actual total number of digital certificate signings, the number of public signatures, and the number of private signatures.

[0128] The printing module of the online printing electronic signing service supports the business system to preview and print the electronic document online on the browser after the electronic document is signed. There is no need to integrate other additional printing components into the business system, thus solving the problem that the electronic signing platform in the industry only has the ability to stamp or digitally sign, and basically has no support for online printing.
