Blockchain privacy data sharing method based on zero-knowledge proof

Abstract

The invention belongs to the technical field of blockchain and industrial privacy data protection, and discloses a blockchain privacy data sharing method based on zero-knowledge proof. Aiming at the problem that industrial privacy data is difficult to share among various industrial institutions, this method realizes data sharing through smart contracts, and at the same time cooperates with zero-knowledge proof technology to realize the authenticity verification of industrial privacy data and processing results, and realizes industrial privacy. The availability of data to the user is invisible, which ensures the privacy of the data and avoids the problem of secondary sales of the data by the data user; for the protection of core data by various industrial institutions, the display data and the sale of data caused by fraudulent core data To solve different problems, the present invention uses the zero-knowledge proof technology to prove the data on the chain and store the certificate, realizes the user's independent verification of the core data without publicizing the core data, and ensures the authenticity of the core data.

Description

technical field [0001] The invention belongs to the technical field of blockchain and industrial privacy data protection, and in particular relates to a blockchain privacy data sharing method based on zero-knowledge proof. Background technique [0002] With the rapid development of the digital industry, more and more attention has been paid to the security of industrial big data. Due to its characteristics of decentralization, security and trustworthiness, and common maintenance, blockchain provides a credible platform for the synchronization and sharing of industrial big data. communication environment. [0003] At present, the method of industrial big data synchronization based on blockchain has gradually become the main method for data synchronization and sharing among major industrial organizations. When major industrial organizations share industrial data, they often need to store industrial data on the chain. , although this method is open and transparent, it has the ...

AI Technical Summary

Problems solved by technology

[0004] 1. When industrial organizations share industrial big data transactions, some industrial data often contain various private data. It is difficult for private data to be truly shared among various industrial organizations, resulting in a waste of private data;

[0005] 2. It is easy to cause the leakage of private data

After the industrial data is sold, the user can save it locally, and it can be used multiple times in one transaction, and the illegal purchaser can conduct a second sale, which is not conducive to maintaining the rights and interests of the original party of the data;

[0006] 3. Privacy data is easily modified, making it impossible for the buyer to verify the authenticity of the privacy data

[0007] When some industrial organizations sell industrial data, in order to protect the core data (that is, private data), they will modify various core data and contribute wrong data to the user, but the user cannot know the authenticity of the purchased data
