Method and system for managing commercial secret based on block chain negotiation encryption

Abstract

The invention relates to a method and a system for managing commercial secret based on block chain negotiation encryption. A plurality of company legal persons and natural persons with different levels inside the company form N nodes; each time a contract is successfully signed, a record is constructed and a new block is formed; the block comprises a contract page label type and a contract sectiontype; the block also comprises a two-dimensional code generating module; when different nodes check, corresponding two-dimensional codes are generated for obtaining corresponding contract informationaccording to difference of jurisdiction of the different nodes to check the block; the contract page and the contract section character image regions with normalized size are subjected to uniform gridding coverage; the contract page and the contract section character images are divided into a plurality of attribute regions, wherein each small attribute calculating grid is a sub-qualitative mapping cluster; and the two-dimensional code of a corresponding content is generated according to the query jurisdiction type and the attribute of the sub-qualitative mapping cluster. The method and the system for managing commercial secret based on block chain negotiation encryption in the invention realize a new management mode in the commercial secret field, thereby significantly reducing the risk of leakage of the commercial leakage in the related contract signing process and reducing the occurrence of error rate; moreover, the accuracy rate aspect is greatly enhanced; the management efficiencyin the commercial secret contract field is enhanced; and the user experience is enhanced.

Description

technical field [0001] The invention relates to the technical fields of block chain, image processing and information security, in particular to a method for managing business secrets based on block chain negotiation and encryption. Background technique [0002] With the development of Internet technology, the decentralization of information has been popularized, such as distributed systems, Bitcoin, etc. have been applied. This method can not only reduce transaction costs, but also enhance the convenience of transactions without introducing unnecessary third parties. To a certain extent, the blockchain provides the possibility to realize this method. [0003] The blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and uses cryptography to ensure a non-tamperable and unforgeable distributed accounting system. The blockchain records All value exchange activities that occur ensure the integrity of the database, and a...

Problems solved by technology

[0004] In the existing technology, the signing of contracts is mostly drawn up in the form of electronic storage and display, but in the blockchain verification mechanism and consensus mechanism, a lot of information has to be exposed in the form of plain text, resulting in a lot of private information being leaked. However, the existing centralized trading mechanism has led to increased transaction costs. How to ensure that privacy is not leaked while reducing transaction costs and improving intelligence has become a research topic. In the service industry, especially in the field of business secrets, for related The degree of process changes is relatively frequent. For example, the signed contract can only be completed through the cooperation between multiple departments of the company and multiple links under the blockchain model, and the content of the contract involves the company’s internal business secrets, especially some important clauses. If too many people see it, the confidentiality effect will be poor, and the completion of the contract signing requires frequent changes and electronic circulation, and how to protect the information and reduce the error rate in the operation process has become a more important research content
