基于智能合约的双链数据共享系统
Double-Chain Hybrid Data Sharing System Based on Smart Contract
摘要
Abstract
In the traditional data sharing model,the data is stored in the central server and authority is centralized to the center server,generating the problem of single point of failure,single point at-tack,poor data security,and restricted access control.To solve the above-mentioned problem,this paper designs a new double-chain hybrid data sharing system based on the smart contract on block-chain.The system implements distributed data storage through the InterPlanetary File System(IPFS),which solves the problem of single point of failure and single point of attack caused by cen-tralized data storage.With the combination of the consortium blockchain and the private chain,the data is protected from illegal tampering utilizing the immutable property of blockchain.Through the smart contracts deployed on the blockchain,the system authenticates user identity,sets data access policies,and achieves flexible data sharing and access control.The system access records are trans-parent and traceable,solving the problem that traditional center server illegal authorization and other malicious behavior can not be monitored.关键词
