AI Technical Summary

Technical Problem

In the existing electronic document signing process, the manual drag-and-drop signing method is inefficient, inaccurate, and prone to errors, especially in documents with multiple signers and multiple pages, where there are risks of signature position misalignment and identity verification.

Method used

By automatically parsing the signature lines in documents, extracting the name and position below the lines, and performing a double match with the filing list, the system automatically renders and aligns the signature materials, ensuring a unique correspondence between the signature and the identity.

Benefits of technology

It achieves automated positioning and filling of multiple signatures, reducing signing time from minutes to seconds, ensuring precise alignment of signature positions, and meeting the compliance requirements of listed companies' information disclosure.

Abstract

The application relates to the technical field of information processing, and discloses a signing method and device of an electronic document, a computer device and a storage medium. The method comprises the following steps: obtaining a to-be-signed document and parsing the to-be-signed document to obtain a structured text and a graphic element coordinate; obtaining a signing subject record list containing a name, a legal duty and an electronic signature material; performing column detection on the to-be-signed document to determine a column boundary; screening a signature line from a horizontal line segment, which meets a preset condition, assigning a signature position identifier and determining a corresponding column; defining an exclusive matching area below the horizontal line to extract a signer's name and duty and establish a binding relationship; matching the name with the record list, and performing a normalized comparison on the duty to confirm an effective signing subject; obtaining a corresponding signature material, and rendering the signature above the horizontal line with the top boundary of the horizontal line as a reference and with the bottom adjacent and horizontally centered. The application can automatically complete signature position recognition, subject matching and signature rendering, avoids misplacement and misplacement of different names and duties, and improves signing efficiency and compliance.
