Embodiment Construction
[0039] as example figure 1 , example figure 2 and example image 3 It shows the file structure of ordinary electronic contract documents, the difference between the structure of ordinary electronic contract documents and the structure of electronic contract documents with security tracking, taking PDF as the carrier of electronic contracts as an example. Ordinary electronic contracts are to digitally sign contract documents.
[0040] Such as image 3 As shown, the secure electronic contract document is the electronic contract platform in figure 2 The end of the electronic contract document shown, with the security module inserted. The secure electronic contract document structure consists of the traditional file structure file header, file content, cross-reference table and file footer plus digitally signed content, digital signature cross-reference table and file footer, and finally the cross-reference table and file footer of the security module . The security module...

The invention provides a method for guaranteeing the safety of an electronic contract, and relates to an electronic contract platform, an electronic contract operation record safety module, an operation behavior information data analysis center and a contract block chain, and the method comprises the following steps: S1, users of two parties of a contract sign the electronic contract on the electronic contract platform; S2, the electronic contract platform pushes a signed common electronic contract to a contract blockchain node through a blockchain interface request, encrypts the signed electronic contract content, rewrites the encrypted electronic contract content into a new electronic contract document, and adds a security module code to form a security electronic contract document; S3,when the user downloads the security electronic contract on the electronic contract platform, starting the electronic contract platform; when the security electronic contract is opened locally, security code authentication is required to be performed on the security electronic contract, and no matter whether security code authentication succeeds or fails, when the contract is opened, the securitymodule can acquire the current file opening environment of the electronic contract file; and S4, the security module of the security electronic contract sends the collected information to an operationbehavior information data analysis center in a UNC path mode, and the operation behavior information data analysis center analyzes whether a security risk exists in the opening environment of the security electronic contract.
Description
technical field [0001] The invention relates to a method for processing electronic contracts, in particular to a method for ensuring the security of electronic contracts. Background technique [0002] Electronic contract is a neutral, notarized, credible, safe, legal and compliant service for enterprises and individual users. [0003] At present, electronic contracts mainly use core technologies such as segmental encryption of electronic contract documents, privacy protection, and original text sandbox protection to ensure the security of user contract documents. After the signed electronic contract is downloaded, not only the content cannot be changed, but also the chapter on the electronic contract contains the CA digital certificate specially issued by the national authority and is stamped with the time stamp of the National Time Service Center, which is legally effective. But now there is a security risk in electronic contracts that once the carrier of the electronic co...
