The security of medical information has become a significant challenge with the move from traditional filing systems to electronic records. This study proposes the use of blockchain technology to address these concerns. The system registers patients and medical staff with unique IDs and stores patient diagnoses as immutable records on the blockchain. A central interplanetary file system stores the collected data, which can be accessed by authorized users like nurses, pharmacists, and patients via special access details. Users must log in before accessing medical records through the Electronic Record Management system. This approach can be scaled to multiple hospitals. After testing, the system showed some latency issues with 100 nodes, but performance improved with more nodes (300-500), demonstrating better scalability as the system handles more data and hospitals. Overall, the proposed blockchain-based system offers a secure, scalable solution for managing and accessing medical records.
随着从传统档案系统向电子记录的转变，医疗信息安全已成为一项重大挑战。本研究提出使用区块链技术来解决这些问题。该系统为患者和医护人员注册唯一ID，并将患者诊断作为不可变记录存储在区块链上。一个中央星际文件系统存储收集到的数据，护士、药剂师和患者等授权用户可以通过特殊访问细节访问这些数据。用户必须通过电子记录管理系统登录后才能访问医疗记录。这种方法可以扩展到多家医院。经过测试，该系统在100个节点时出现了一些延迟问题，但随着节点数量增加（300 - 500个）性能有所改善，表明随着系统处理更多数据和医院，其扩展性更好。总体而言，所提出的基于区块链的系统为管理和访问医疗记录提供了一个安全、可扩展的解决方案。
