Example Embodiment
[0031] Example one
[0032] This embodiment provides a method of privacy protection based on group-signed regulatory block chain transaction;
[0033] The privacy protection method of block chain transaction based on group signature, including:
[0034] S101: Each transaction node is sent to the notarized mechanism node. After the notarized mechanism node is verified, the authentication certificate for each transaction node is generated; where the transaction node, including: transaction initiation node and transaction receiving node;
[0035] S102: The transaction initiation node sends the group administrator node to the group administration, the group administrator node and the notarized authority node interaction, to complete the identity legal verification of the trading node applying for the group; after verify the identity, the transaction initiates nodes and group administrators The node interacts, generates a group signature of the transaction;
[0036] S103: After receivi...
Example Embodiment
[0122] Example 2
[0123] This embodiment provides a privacy protection system based on group-signed regulatory block chain transaction;
[0124] Based on group-signed regulatory block chain transaction privacy protection system, including: Several transaction nodes, block chains, the block chain with a notarized mechanism node, group administrator node, and multiple audit nodes; Notary agency nodes, group administrator nodes, and multiple audit nodes together form an audit node network;
[0125] Each transaction node is sent to the notarized mechanism node. After the notarized mechanism node is verified, the authentication certificate for each transaction initiation node and transaction receiving node is generated; where the transaction node, including: transaction initiation node and transaction receiving node ;
[0126] The trading node sends the group administrator node to the group application, the group administrator node and the notarized authority node interaction to comple...
