Abstract

The present invention discloses a blockchain-based data sharing method and system. The method includes: a supervisory node encrypts all data reached consensus through the blockchain network, and records all encrypted data on the blockchain; the first Member nodes submit a data sharing request through the blockchain network, and the data requested by the data sharing request includes at least the data provided by the second member node; the supervisory node and the second member node jointly approve the data sharing request; if the data sharing request is approved , then the supervisory node decrypts the data requested by the data sharing request from the blockchain; and encrypts the requested data based on the public key of the first member node, and returns it to the first member node, so that the first member node Get the requested data by decrypting it with your own private key. The embodiments of the present invention can ensure the security of data sharing, and can avoid non-compliance or illegal situations that are easily caused by data sharing without supervision and processing.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a data sharing method and system based on block chains. Background technique [0002] In recent years, blockchain (Blockchain) technology has received widespread attention and development, and is gradually being applied in many fields such as banking, finance, and insurance. Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is a distributed database system that is collectively participated by multiple nodes. [0003] In the blockchain distributed system, the existing data sharing method is usually that the data provider publishes the data description information to the blockchain, and the data demander obtains the data description information released by the data provider from the blockchain, and selects Target data, and publish the data permission...
