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.
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.
