Embodiment Construction

[0008] A technology for exchanging official documents based on electronic seals, comprising the following steps: (1) adding watermarks to documents;

[0009] (2) Add a signature to the file; (3) Verify the signature message; (4) Verify the signature.

[0010] The method for adding watermark includes the following steps: the method for adding watermark is to convert the watermark into a watermark image and map it into an integer vector, and superimpose the integer vector generation algorithm formed by mapping the original document and the watermark watermark image together.

[0011] Integer watermark vectors can provide very flexible means of authentication and access control through the combination of public key systems, and multiple pseudo-watermarks are used to protect certified watermarks [3] Only the watermarks that know the discrete logarithm value are true watermarks The security is proportional to the number of false watermarks. However, the algorithm does not encrypt t...

Abstract

The invention relates to a document exchange technology based on an electronic seal, which is characterized by comprising the following steps: a watermark is added to the document; a signature is added to the document; a signature message is authenticated; and the signature is authenticated. According to the document exchange technology based on the electronic seal, the sealed electronic document can be not exchanged randomly; and when a controlled electronic document needs transmission, the controlled electronic document needs to pass auditing in a specified unit and obtains authorization, but the system can not stop all P2P transmission, as for the electronic document with the electronic seal, the nature of an undeniable signature can be realized when the electronic seal is produced.

Description

technical field [0001] The invention relates to an electronic seal-based official document exchange technology. Background technique [0002] The electronic document exchange system is an information system that realizes the electronic transmission and management of official documents exchanged by various government agencies and units. It includes two aspects. The office automation systems that have been established by the commissions, offices, and bureaus will gradually build a government network and information platform with unified standards, complete functions, and safety and reliability. Information between heterogeneous systems and old and new systems will be uniformly exchanged transparently through this platform; another On the one hand, planning and establishing standards and specifications for government electronic official documents, and relying on subsystems such as electronic seals, digital signatures, and electronic identity authentication, to provide reliable ...
