Problems solved by technology

As an important branch of the blockchain, the alliance chain has the characteristics of fast transaction speed, low cost, and strong controllability. However, within the alliance chain, the data is completely open, as long as users in the alliance chain can access the data in the blockchain. Arbitrary data, private data and private data in the alliance chain cannot be well protected, resulting in users being unable to realize business scenarios with private data and private data, which restricts the development of the alliance chain

Embodiment Construction

[0037] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0038] like figure 1 As shown, a private and privacy data protection mechanism in the consortium chain includes nodes and sorting services. The nodes communicate with the sorting services through channels. The nodes store ledger files, private databases, private databases and general databases. Private The database, the privacy database and the general database are connected to the account book file through the peer node; the private data, privacy data and general data are stored in the account book file.

[0039] A peer node joins one or more channels, and the channels are isolated from each other.

[0040] The latest data status of the private data, privacy data, and general data will be updated to the corresponding private database, privacy database, and general database in time.

[0041] The protection of the private data set...

Abstract

The invention provides a private and private data protection mechanism in an alliance chain. The private and private data protection mechanism comprises a node and a sorting service, the node is in communication connection with the sorting service through a channel; an account book file, a private database, a private database and a general database are stored in the node, and the private database,the private database and the general database are connected with the account book file through peer nodes; and private data, private data and general data are stored in the account book file. The method has the beneficial effects that the security protection of private and private data in the alliance chain can be effectively realized, and the private and private data is prevented from being disclosed to all members in the alliance chain.

Description

technical field [0001] The invention relates to a private and privacy data protection mechanism in an alliance chain, belonging to the technical field of block chains. Background technique [0002] Blockchain technology integrates cryptography, P2P network, distributed storage technology, consensus protocol, smart contract and other technologies, which makes it have natural advantages in data security. As an important branch of the blockchain, the alliance chain has the characteristics of fast transaction speed, low cost, and strong controllability. However, within the alliance chain, the data is completely open, as long as users in the alliance chain can access the data in the blockchain. Arbitrary data, private data and private data in the alliance chain cannot be well protected, resulting in users being unable to realize business scenarios with private data and private data, which restricts the development of the alliance chain.
