Problems solved by technology

[0005] However, the electronic file itself has the characteristic of being easily modified, and the existing electronic seam stamp scheme only saves the information of the electronic seam stamp in the electronic file as visual information such as display and printing, so this information is easy to be tampered with. Once the information is tampered with, it is equivalent to tampering with the image block stamped on the edge of the page, which will damage the legitimacy and authority of the seam seal of the electronic document

Abstract

The embodiment of the invention discloses an electronic document paging seal signing method and device, and equipment. The electronic document paging seal signing scheme comprises the steps that afteran electronic document to be signed and an electronic seal are obtained, a page needing to be stamped with a paging seal, a paging seal block and a stamping position are determined according to a preset paging seal rule; electronic data corresponding to a specified position, covered by the paging seal block, in the page is determined; and the electronic data as first incremental data of the to-be-signed electronic document is added to the to-be-signed electronic document, and the to-be-signed electronic document is signed.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to a method, device and equipment for signing an electronic document with a seam stamp. Background technique [0002] Stamping a paper document (such as a contract document) refers to stamping a multi-page paper document, when it is not necessary to stamp each page separately but to avoid some of the pages from being replaced, The edge seams of multiple pages can be joined together and the same stamp can be stamped, so that a part of the pattern of the stamp can be obtained at the edge seams of each page, and only the edges of the stamped multiple pages can be stitched together Only together can the pattern of the seal be completely restored. [0003] At present, with the development of Internet technology, electronic seal technology has gradually been promoted and applied. Electronic seal refers to the simulation of traditional physical seals with advanced digital techn...
