摘要
为解决患者跨医院就诊中的电子病历信任问题,推动医院间电子病历互联互通。利用区块链不可篡改、真实性、去中心化的特性,基于密码学、联盟区块链和分布式行星文件系统提出一种电子病历可信存证方法。通过电子病历哈希值作为真实凭证,保证电子病历是可信的。并且,患者自身参与调度过程,实现电子病历用户可控性。实验结果表明,该方法提高了跨医院间电子病历共享的可信度,有效实现了用户可控,并从效率方面证明了该方法的可行性。
To solve the problem of trust in electronic medical records in cross-hospital visits of patients and to promote the interoperability of electronic medical records among hospitals,a trustworthy evidence storage method for electronic medical records is proposed based on cryptography,consortium blockchain and distributed planetary file system using the characteristics of blockchain as tamper-evident,authenticity and decentralization.The electronic medical record was guaranteed to be trustworthy by using the electronic medical record hash value as the real credential.Moreover,patients themselves participated in the scheduling process to achieve user controllability of electronic medical records.The experimental results show that the method improves the trustworthiness of electronic medical record sharing across hospitals,effectively realizes user controllability,and proves the feasibility of the method in terms of efficiency.
