摘　　要：当前个人健康记录(PHR:Personal Health Records)存在着存储不安全和难以共享的问题。为提高PHR的安全性和共享性,提出一种基于超级帐本(Hyperledger)和手指静脉(FV:Finger Vein)特征身份验证的安全共享模型。PHR提供方在录入医疗记录时将FV特征与临床医生的私钥签名结合,生成PHR索引。然后将PHR的索引存储在Hyperledger Fabric中,将真正的隐私数据存储在Filecoin中,减少了存储成本和链上存储压力。同时,设计了PHR访问控制合约防止恶意节点攻击。实验结果表明,该模型在性能和存储上有显著的优势。Current PHR(Personal Health Records)have the challenges of insecure storage and difficulty in sharing.In order to improve the security and sharing of PHR,a secure sharing model based on Hyperledger and FV(Finger Vein)feature authentication is proposed.The PHR provider combines the FV feature with the clinician’s private key signature when entering the medical record to generate a PHR index.Then store the PHR index in Hyperledger Fabric,and store the real private data in Filecoin,reducing storage costs and on-chain storage pressure.And a PHR access control contract is designed to prevent malicious node attacks.Experimental results show that this model has significant advantages in performance and storage.
