Problems solved by technology
[0002] At present, all the electronic signature schemes used in the paperless office process approval on the market are to electronically sign the result documents after the process approval to prevent tampering. During the process approval process, this method cannot save the business in the process Changes in data, only the final approval results can be displayed
It is impossible to check the business data changed during the approval process and the approval opinions of intermediate nodes passed through the approval process such as callback through the result file

Embodiment Construction
[0021] The technical scheme of the present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0022] Such as figure 1 As shown, the electronic signature method applicable to the whole process of the present invention includes the following steps:
[0023] (1) Define special character generation rules, and generate PDF approval documents with special characters in reports or other systems. The special character generation rules are [ ],use"[ ]" or other pairs of characters include the text field Id.
[0024] (2) Use third-party components to analyze the position information of all line segments in the PDF document, determine the intersection of line segments, and identify the rectangular area composed of line segments;
[0025] In this embodiment, the iTextSharp component is used as a third-party component, and by implementing the method of the IExtRenderListener interface, when the component traverses all PDF elements, the intersec...

The invention relates to an electronic signature method suitable for full-flow proceduring, which comprises the following steps: defining a special character generation rule, and generating a PDF approval file with special characters in a report or other systems; analyzing the position information of all line segments in the PDF file, judging the intersection condition of the line segments, and identifying a rectangular region formed by the line segments; identifying the position of each character in the PDF document and the sequence of the characters, identifying special characters, and storing the positions and areas of the special characters; comparing the identified special character position with the identified rectangular area, and finding out the minimum rectangular area where the special character is located; generating a text field form in a corresponding position area in the PDF file according to the business data or the position of the rectangular area through the position relation between the found special characters and the rectangular area; before process approval, filling the PDF file with the business data corresponding to the approval form; and performing electronic signature operation on the PDF file. The method can prevent the whole approval process from being tampered.
Description
Technical field [0001] The present invention relates to an electronic signature, and specifically refers to an electronic signature method suitable for the whole process. Background technique [0002] At present, the electronic signature scheme adopted in all paperless office process approvals on the market is to electronically sign the result document after the process approval to prevent tampering. During the process approval process, this method cannot save the business in the process Data changes can only show the final approval result. It is not possible to check the changed business data during the approval process through the result file and return the approval opinions of the intermediate nodes in the circulation of the approval process. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an electronic signature method suitable for the whole process. The electronic signature me...
