Problems solved by technology

This method of data acquisition is still a legal gray area, and it cannot form a benign and continuous source of data
[0003]The distributed ledger technology and encryption technology of blockchain can improve the security, traceability and transparency of transactions through multi-party redundant backup, but it still exists The data is highly transparent during on-chain transmission and the privacy and identity of data producers can be investigated by certain means

Abstract

The invention provides a data anonymity sharing system and method based on a block chain, and relates to the technical field of computers. The system comprises a data demander and a data sharing party, wherein the data demander comprises a plurality of B-class nodes, and the data sharing party comprises a plurality of A-class nodes; the nodes are mutually connected, and a block chain is established between the B-class nodes; a program running on each node comprises a data transmission module, an integral and value transfer system, an examination module and a data encryption API module; and theB-class node also comprises a state storage module. According to the method, the privacy of a user and the reliability of data can be guaranteed to the maximum extent, the user can obtain a certificate, and information leakage is avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based anonymous data sharing system and method. Background technique [0002] In the Internet era, user data on various existing terminal devices that can collect user data (such as smart home gateways, smart phone applications) is usually obtained by manufacturers in the form of unilateral notification and direct transmission to cloud servers. More and more manufacturers and research institutions need to obtain this kind of data to mine the value of products and services and meet the needs of research and development. However, for users, what information will be obtained and whether access is allowed lacks control and the right to know. As far as manufacturers are concerned, they cannot prove that the user data they have obtained has been authorized by the user and does not contain user privacy information. The phenomenon that a large amount of data cont...
