Abstract

The present invention relates to a block chain privacy data transmission method and a block chain privacy data transmission system. The block chain privacy data transmission method includes: sending a consensus request to each member node; performing violation verification on each member node; If all member nodes do not violate the rules within a predetermined period of time, each member node will be controlled to transmit private data to the consensus service node; if any member node violates the rules within the predetermined time, each member node will be controlled to terminate the transmission of private data. The blockchain privacy data transmission method and the blockchain privacy data transmission system of the present invention verify the violation of each member node, which can prevent malicious collusion between nodes during the privacy data transmission process, and can be timely when any member node violates the rules. Terminate the transmission of private data, thereby preventing the leakage of private data and improving the security of blockchain private data transmission.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain privacy data transmission method and a privacy data transmission system. Background technique [0002] At present, the privacy data protection schemes of the blockchain are as follows: [0003] 1) Off-chain storage: Store the private data that needs to be protected outside the chain, and put the public data on the distributed ledger. [0004] 2) Ledger isolation: Store the ledgers with different privacy requirements in different distributed ledgers. [0005] 3) Encryption protection: encryption algorithms are mainly divided into symmetric encryption and asymmetric encryption. [0006] In the ledger isolation solution, all the ledger data will be transmitted to the consensus service node. During the transmission process, if the nodes collude maliciously and steal the private data of another part of the nodes, the private data will be leaked. [0007] Therefor...
