Description

Technical Field

[0001] The present invention belongs to the technical field of electronic signatures, and in particular relates to a method for locating electronic signatures in a PDF webpage. Background Art

[0002] As a tool for identification or signing on behalf of individuals and units, seals still play an important role in today's society. In work, the signatures of various documents cannot be separated from seals, and because seals are accompanied by legal effects, the use of seals is of great significance to the interests of individuals or groups.

[0003] In today's society, paperless office is a necessary means to improve efficiency and reduce costs. Due to habit, even in a paperless office system, people are still accustomed to using electronic signatures as a means to define the legal effect of documents. Therefore, operators are required to electronically stamp on computer web pages.

[0004] The stamping method in the national secret electronic signature is complicated to operate, and it is impossible to stamp multiple seals in an electronic document at one time, which greatly reduces the stamping efficiency. In particular, it is impossible to add a designated seal to all the locations where stamps are required, so it cannot meet people's needs.

[0005] The existing methods of stamping electronic signatures on electronic documents mostly preset multiple signature templates, specify the signature position of each template, and then the stamping program obtains the signature position by identifying which signature template the document to be signed corresponds to. This method has great limitations and requires staff to do a lot of setup work in advance. In addition, manual operation cannot be implemented for non-standard templates.

[0006] The applicant's previous patent application 201811080624.3 discloses a method for positioning a PDF electronic signature on a web page. The method manually moves the signature by moving the mouse, and in order to ensure the integrity of the signature on the page, the movable position of the signature on the page is limited.

[0007] Although this method solves the manual operation of non-standard contract templates, it requires manual selection of the stamping position on the web page, which can easily result in missed or incorrect stamping, causing the stamped document to become invalid.

[0008] In order to solve the above-mentioned problems and realize the fast and accurate signing of non-standard contract templates, the inventor proposed this application. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and achieve rapid and accurate signing of non-standard contract templates.

[0010] To achieve the above object, the technical solution adopted by the present invention is:

[0011] A method for locating an electronic signature in a webpage PDF comprises the following steps:

[0012] S1. Preset the positioning character corresponding to each signature and the distance r from the center of the signature to the page boundary, and ensure that the r value is greater than or equal to the distance R from the center of the signature to the farthest end;

[0013] S2. Select the signature to be used; the mouse automatically obtains the center position of the corresponding signature, and the signature moves with the mouse;

[0014] S3, reading the preset positioning characters of the signature in S1, matching them with the characters in the webpage PDF document, and marking all positioning characters in the webpage PDF document;

[0015] S4, manually operate the mouse or scroll wheel to slide freely, and when the mouse stops moving, the mouse is automatically moved to the center position of the nearest positioning character in the webpage PDF document;

[0016] S5. When the distance h between the position where the mouse stops and the border of the nearest webpage PDF document is less than r, the mouse is automatically corrected and shifted in a direction that increases h. This process is repeated until the position where the mouse stops is greater than or equal to r.

[0017] S6, manually determine whether the position corrected by S5 is the position where the stamp needs to be stamped, if yes, click the mouse to confirm the stamping; if no, no click operation is required;

[0018] S7. Repeat steps S4 to S6 until all locations that require stamping are stamped, and click the mouse to cancel the selected signature.

[0019] Furthermore, step S8 is included: after step S7 is completed, if other signatures need to be stamped, steps S2 to S7 can be repeated.

[0020] Furthermore, in step S6, if an erroneous official seal is affixed, the erroneous official seal can be affixed by clicking confirm again to cancel the affixing.

[0021] Preferably, the positioning characters of the official seal and contract seal in S1 are the company name.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. No need to preset stamp templates, you can freely select the stamp position according to the actual situation;

[0024] 2. Automatically identify potential stamping positions, facilitate operation, and prevent missed or wrong stamping;

[0025] 3. Automatically identify the distance between the signature and the page boundary, and correct the mouse position to ensure that the stamped signature is fully reflected on the page. DETAILED DESCRIPTION
