Abstract

The invention is suitable for the technical field of computers, and provides a signature position determination method, device and equipment based on a PDF file. The method comprises the steps of obtaining file attributes of a PDF file to be signed, and determining keywords used for representing signers according to the file attributes; determining a target signature format of the keyword according to a preset keyword configuration table; carrying out text analysis processing on the PDF file to be signed to obtain a plurality of block data set based on a context sequence and position information of each block data; and according to the context information of the plurality of block data, determining target block data which contains the keyword and is matched with the target signature formatof the keyword, and determining the position represented by the position information of the target block data as the signature position of the PDF file to be signed. According to the signature position determination method based on the PDF file provided by the embodiment of the invention, automatic positioning of the signature position of the PDF file is realized.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a method, device and equipment for determining a signature position based on a PDF file. Background technique [0002] With the development of Internet technology, the demand for signing documents in business activities is increasing. [0003] In order to solve the problem of inefficiency in the traditional signing method, the electronic signature method based on blockchain is usually used to sign PDF files, that is, based on the distributed data and consensus mechanism of blockchain to realize the multi-party rapid signing of electronic documents. [0004] The blockchain-based electronic signature method can only realize the automatic signing of PDF electronic documents, but cannot automatically identify the signature position, and needs to manually pre-designate the signature position of each document to be signed; due to the diversity of the documents t...
