A blockchain-based transaction system for private data sharing and trading
文献摘要：
To address the private data management problems and realize privacy-preserving data sharing, a blockchain-based transaction system named Ecare featuring information transparency, fairness and scalability is proposed. The proposed system formulates multiple private data access control strategies, and realizes data trading and sharing through on-chain transactions, which makes transaction records transparent and immutable. In our system, the private data are encrypted, and the role-based account model ensures that access to the data requires owner's authorization. Moreover, a new consensus protocol named Proof of Transactions (PoT) proposed by ourselves has been used to improve consensus efficiency. The value of Ecare is not only that it aggregates telemedicine, data transactions, and other features, but also that it translates these actions into transaction events stored in the blockchain, making them transparent and immutable to all participants. The proposed system can be extended to more general big data privacy protection and data transaction scenarios.
