Abstract

An Electronic Health Record (EHR) store essential and sensitive patient's medical information. Since health information is highly confidential data, it should be accessible with the consent of the patient. Blockchain based EHR management system offers improvised privacy and patient-centric approach. EHR management systems are available with multiple blockchain platforms. Generally, EHRs are maintained at several independent blockchain platforms. EHR management systems should be capable of securely exchange data on cross platform blockchain network. The interoperability in such blockchain platforms should facilitate seamless cross-chain interaction and information exchange. This article proposes a method that facilitates secure EHR exchange on Ethereum and Hyperledger fabric network using hepatitis dataset. The key contributions of the proposed method include:

•
Hash lock based interoperable cross-chain method for EHR exchange across Ethereum and Hyperledger fabric.
•
Additional security to the EHR is ensured by partitioning EHR as on-chain (blockchain platform) and off-chain InterPlanetary File System (IPFS)
•
Secure Password Authentication-Based Key Exchange (SPAKE) based session management for EHR exchange across two parties.

The proposed patient centric method is validated to ensures the successful exchange of patient EHR across Ethereum and Hyperledger fabric.

跨平台区块链网络电子健康记录交换的安全互操作方法

电子病历（EHR）存储病人重要而敏感的医疗信息。由于健康信息是高度机密的数据，因此必须在征得患者同意后才能访问。基于区块链的电子病历管理系统提供了更好的隐私保护和以患者为中心的方法。电子健康记录管理系统有多种区块链平台。一般来说，电子健康记录维护在多个独立的区块链平台上。电子健康记录管理系统应能够在跨平台区块链网络上安全地交换数据。这些区块链平台的互操作性应有利于无缝跨链交互和信息交换。本文提出了一种方法，利用肝炎数据集促进以太坊和超级账本网络上的安全电子病历交换。通过将电子健康记录划分为链上（区块链平台）和链下专有文件系统（IPFS），确保了电子健康记录的额外安全性--基于安全密码验证的密钥交换（SPAKE）会话管理，用于双方的电子健康记录交换。
