Privacy management system and method for blockchain intelligent contract platform

Abstract

The invention discloses a privacy management system and method for a blockchain smart contract platform. The privacy management system is applied to a network environment formed by signing an intelligent contract between a contract initiator and a plurality of contract signers, the privacy management system comprises an intelligent contract subsystem, a private contract subsystem and an encryptionsubsystem, and the intelligent contract subsystem comprises an intelligent contract submission module and an intelligent contract execution module; the private contract subsystem comprises an encrypted contract storage module and an encrypted contract query module; the encryption subsystem comprises a public and private key generation module, a public and private key verification module and a contract encryption and decryption module ENC. According to the invention, the compatibility of the private contract and the public contract can be realized, and privacy management and decentralization are both considered, so that the application range of the intelligent contract can be expanded, the reliability and effectiveness of blockchain technology application can be improved, and the application cost of the blockchain technology can be greatly reduced.

Description

technical field [0001] The invention relates to the field of blockchain general platforms, in particular to a privacy management system and method for a blockchain smart contract platform. Background technique [0002] Today, the application of blockchain technology has been extended to many fields such as digital finance, Internet of Things, intelligent manufacturing, supply chain management, and digital asset transactions.

Problems solved by technology

At this stage, blockchain smart contract technology still has deficiencies, blindly emphasizing decentralization and openness, but it is impossible to disclose all data in practical application scenarios, and the current blockchain smart contract platform cannot take into account the needs of privacy management , in the process of pursuing privacy, private contracts have emerged, forming different positioning and separation of alliance chains, private chains and public chains, and barriers that are incompatible between private contracts and public contracts, affecting the application efficiency and efficiency of blockchain smart contracts. Experience, which hinders the speed of its empowerment of the real economy and its integration with the economic society
