Electronic signature multiplexing method and device, equipment and storage medium

Abstract

The invention relates to the field of block chains, and discloses an electronic signature multiplexing method and device, equipment and a storage medium, which are used for improving the confirmationefficiency of a user for confirming a basic to-be-signed file. The electronic signature multiplexing method comprises the following steps: acquiring a plurality of initial signature keywords in a plurality of initial files to be signed, and hiding the initial signature keywords except the positions of the plurality of initial signature keywords by utilizing a hiding function; obtaining an electronic signature from the target basic to-be-signed file to obtain a target signed file; generating an encrypted data string by adopting an asymmetric encryption algorithm to obtain integrated signature data; transmitting the integrated signature data to other basic files to be signed, verifying the integrated signature data, and mapping the verified integrated signature data to other basic files to be signed by using a preset mapping function to obtain a plurality of other signed files; and combining the target signed file with a plurality of other signed files to obtain a complete signed file, wherein the initial to-be-signed file can be stored in the block chain.

Description

technical field [0001] The present invention relates to the field of smart contract signing, in particular to an electronic signature multiplexing method, device, equipment and storage medium. Background technique [0002] With the rapid development of computer technology, in order to facilitate user operations and improve user experience, various industries order users to directly confirm text information in electronic files in many scenarios that require users to confirm text information. [0003] After confirming the text information in the electronic file, the user needs to sign after the corresponding signature keyword position at the end of the electronic file. Using the existing signature plug-in software development kit (software development kit, SDK), the electronic name can be signed after the position of the signature keyword in the document to be signed, but when the number of electronic documents that need to be confirmed increases, the user needs to separately ...

AI Technical Summary

Problems solved by technology

Using the existing signature plug-in software development kit (software development kit, SDK), the electronic name can be signed after the position of the signature keyword in the document to be signed, but when the number of electronic documents that need to be confirmed increases, the user needs to separately Signing multiple documents to be signed is prone to abnormal signatures that cause users to re-sign. Users sign their names multiple times. Such repeated operations lead to low efficiency for users to confirm documents.
