摘要
Abstract
In view of the problems of privacy protection,data security and storage,data sharing and other aspects in the electronic medical record system,a solution based on the consortium chain and the SM9 algorithm is proposed.This solution uses desensitiza-tion technology and the SM9 algorithm to protect the privacy and encrypt the electronic medical records.The encrypted electronic medical record files are stored using the InterPlanetary File System(IPFS),and the consortium chain is used to store its index to achieve lightweight storage of electronic medical records.At the same time,smart contracts are used to search and access control files,and the SM9 algorithm is used to encrypt the serial key to achieve secure sharing of electronic medical records.Finally,a com-prehensive performance analysis of the solution is conducted,and it is comprehensively compared with existing solutions.The com-parison results show that in terms of structure,this solution adopts a single-chain structure,which reduces the complexity of the sys-tem compared with the double-chain structure solution.In terms of storage,the IPFS transmission mode is adopted,which shortens the upload time of large medical records by an average of 13 times compared with traditional file transmission modes.In terms of communication,compared with solutions that do not use the SM9 algorithm,this solution shortens the communication time by more than 30 milliseconds.关键词
