Embodiment Construction

[0026] The present invention proposes a reliable electronic contract storage and verification method, the electronic contract is stored in the form of a compressed package, and the overall packaging structure is composed of three parts, such as figure 1 shown. These three parts are:

[0027] (1) The electronic version of the contract text and contract attachments, supporting common file formats such as DOC, PDF, and JPG;

[0028] (2) Contract text hash value and user group signature. The contract text hash value is composed of the SHA1 value of the contract text and the SHA1 value of the contract attachment. The user group signature consists of the content of the user's digital certificate and the user signature of the contract text hash value Composed of a third-party time source signature, the user signs the hash value of the contract text through his own digital certificate, and obtains the user signature of the contract text hash value. The third-party time source signatu...

Abstract

Provided is an electronic contract storage and validation method. An electronic contract is stored in an encapsulation structure and comprises the part of contract text and contract appendixes in the electronic edition, the part of a contract text hashed value and a user group signature, and the part of a contract hashed value, a service group signature and an electronic contract display page. According to the method, various elements such as the hashed values and the signature values involved in the contract are divided into three parts according to the internal structure, and all the parts form a strict independency relation through Hash calculation and the digital signatures. The method solves the problem that data of a traditional electronic contract are not convenient to use, safety and security of data of the electronic contract are improved, a user can comprehensively browse and read the electronic contract, verify and authenticate the electronic contract conveniently and carry the electronic contract for providing evidence conveniently, and the method has great significance in application and popularization of the electronic contract and has very high practical operation value.

Description

technical field [0001] The invention belongs to the field of computer technology and relates to electronic signature technology, which is used in the electronic transaction process to store and verify electronic contract data signed by transaction parties, and is an electronic contract storage and verification method. Background technique [0002] Since the beginning of the 21st century, electronic communication networks and e-commerce have developed rapidly in our country, and people have begun to use electronic documents, electronic files and electronic data in large quantities to replace traditional paper documents and data exchange. In this case, the traditional paper contract signing mode is increasingly incompatible with the development trend of e-commerce, and electronic contracts have begun to appear. Electronic contracts have many advantages such as convenient use, high transmission efficiency, and low cost. In recent years, with the encouragement and support of th...
