Abstract

Electronic medical records (EMRs) sharing has become a vital component of the modern health care system, which involves patients, The Medical Institution with Medical Records (MI-MR), and The Medical Institution Requiring Medical Records (MI-RMR) within this ecosystem. Currently, a substantial amount of research focuses on the security, authenticity, and privacy of the shared information. However, there is a shortage of attention on design and research that adequately reflect personal rights and interests of patients. We propose a consent-aware EMR sharing method leveraging blockchain technology, which not only preserves patients’ right to be informed, but also fulfills the fundamental needs for security and privacy in EMR sharing. Furthermore, it ensures transparency and decentralization in the sharing process and incorporates on-chain verification mechanisms against malicious alteration of blockchain data. To enhance system scalability, a secure off-chain storage mechanism has been implemented. Our experimental findings underscore the practicality of our smart contract on Ethereum, along with its economic benefits, evaluated using tests conducted on a Ganache-based Ethereum blockchain network and a Remix-based Ethereum blockchain network. The performance and advantages of the proposed architecture have been corroborated through a prototype implementation using Ethereum.

基于区块链的同意感知电子病历共享方法

电子病历（EMR）共享已成为现代医疗保健系统的重要组成部分，在这个生态系统中，病人、有医疗记录的医疗机构（MI-MR）和需要医疗记录的医疗机构（MI-RMR）都参与其中。目前，大量研究都集中在共享信息的安全性、真实性和隐私性上。然而，在充分反映患者个人权益的设计和研究方面却缺乏关注。我们提出了一种利用区块链技术的同意感知 EMR 共享方法，它不仅维护了患者的知情权，还满足了 EMR 共享对安全性和隐私性的基本需求。此外，它还能确保共享过程的透明度和去中心化，并结合链上验证机制，防止区块链数据被恶意篡改。为了提高系统的可扩展性，还实施了安全的链外存储机制。通过在基于 Ganache 的以太坊区块链网络和基于 Remix 的以太坊区块链网络上进行的测试，我们的实验结果证明了我们的智能合约在以太坊上的实用性及其经济效益。拟议架构的性能和优势已通过使用以太坊的原型实施得到证实。

期刊介绍： The quality of software, well-defined interfaces (hardware and software), the process of digitalisation, and accepted standards in these fields are essential for building and exploiting complex computing, communication, multimedia and measuring systems. Standards can simplify the design and construction of individual hardware and software components and help to ensure satisfactory interworking. Computer Standards & Interfaces is an international journal dealing specifically with these topics. The journal • Provides information about activities and progress on the definition of computer standards, software quality, interfaces and methods, at national, European and international levels • Publishes critical comments on standards and standards activities • Disseminates user''s experiences and case studies in the application and exploitation of established or emerging standards, interfaces and methods • Offers a forum for discussion on actual projects, standards, interfaces and methods by recognised experts • Stimulates relevant research by providing a specialised refereed medium.
