Personal Privacy Data Protection and Authorization Framework Based on Double-layer Chain
摘要
Abstract
In view of the frequent occurrence of privacy disclosure events and the current protection meth-ods still couldn't avoid malicious collection and attacks,a personal privacy data protection and authoriza-tion framework based on double-layer chain was proposed.The framework was composed of authentication chain and authorization chain.Through cross chain technology,users could obtain service without provi-ding private data to service providers.The authentication layer was responsible for verifying data and gen-erating data certificates,and the authorization layer was responsible for user authorization to prevent serv-ice providers from obtaining user privacy data.In addition,the improved RAFT algorithm based on the se-quential election and delegated proof of benefit algorithm were proposed to be applied to the authentica-tion layer and the authorization layer respectively,which could improve the speed of consensus and data processing,and solved the problem of how to maintain the public chain without incentive mechanism.The experimental results showed that the proposed framework ensured the authenticity,security and scal-ability of data,and balanced privacy and traceability.关键词
