Research on medical data security sharing model based on blockchain
Aiming at the problems of centralized storage,low sharing efficiency and privacy disclosure of medical data,the security sharing model of medical data based on blockchain was proposed.Firstly,based on the verifiable delay function,the practical Byzantine fault-tolerant algorithm is improved to realize the distributed election of the primary node and ensure the reliability of the primary node.Secondly,the lightning network technology is used to construct the anonymous communication channel under the chain,which solves the problem of anonymous communication in the process of data sharing and improves the efficiency of data sharing.Finally,a complete medical data sharing scheme is designed to realize the security sharing of data between different entities.Compared with existing data sharing schemes,this scheme has advantages in terms of security and consensus efficiency.
