【摘要】 针对生物数据的特点和管理中存在的数据不可信性和安全性问题,提出了一种多链多通道结构的系统。用于联盟区块链的分布式操作系统Hyperledger Fabric技术,提出了一种多链结构,包括三条用于记录数据的区块链和一条用于记录操作内容的区块链,利用多通道实现了节点权限的划分,同时将敏感操作记录连接到了区块链上。系统地解决了生物数据中敏感数据的保密性和敏感操作的事后审计问题,实现了对生物数据的管理和操作,保证了数据的安全性和可信性。更多还原

【Abstract】 Aiming at the problem of data untrustworthiness and security in biological data management, a system with multichannel structure is proposed. The system is based on Hyperledger Fabric, a distributed operating system for consortium blockchains. The system includes three blockchains for recording data and a blockchain for recording operational content. We use multi-channel to realize the division of node privileges and link sensitive operation records to bolckchain. It solves the problems of confidentiality of sensitive data and auditing of sensitive operation on biological data, realizes the management and operation of biological data, and ensures the security and reliability of biological data.更多还原
