Problems solved by technology
The existing electronic seals all electronically sign the entire electronic document, and it is impossible to certify part of the electronic document, such as a single page, or a certain part of the content, and print the electronic document into a paper document and stamp it. However, it is still impossible to authenticate part of the content of the electronic document. When the partial content of the paper document is modified or replaced, it cannot be accurately identified. The security of the combination of the paper document and the electronic document is still not effective. ensure

The invention provides a document signature method, an apparatus, a device and a readable medium. The method comprises the following steps: a splitting step of splitting the content of an electronic document into a plurality of content units; an identification step of allocating independent identification information to each content unit; signing step of electronically signing each content unit with an electronic seal, and generating backup information, wherein the backup information comprises associated information of identification information and signature information; a storage step of storing the backup information of each content unit on an electronic signature server corresponding to the electronic signature. Each content unit of an electronic document can be granted an independent,Unique identification information, each content unit is authenticated by electronic signature, the content unit is modified, the probability of replacement is greatly reduced, the electronic documentcan be effectively counted and managed, the total number of electronic documents and the total number of content units can be quickly queried, and the content of the content unit can be accurately verified.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a file authentication device method, device, device and readable medium. Background technique [0002] With the rapid development of Internet technology and the rise of e-government and e-commerce, electronic seal technology has emerged and has been widely used. [0003] When the existing paper documents are sealed, when the number of pages of the document is relatively large, in order to prevent alteration or forgery, it is usually necessary to add a seam seal to prevent the content of the document from being replaced. However, the seam seal can still be copied by forgery, and the effect of preventing counterfeiting is not very good. The existing electronic seals all electronically sign the entire electronic document, and it is impossible to certify part of the electronic document, such as a single page, or a certain part of the content, and print the electronic do...
