Efficient Health Information Exchange Automation System Based on Blockchain and IPFS

In today's digital era, secure and efficient management of health information is a critical challenge. Centralized health data systems often expose sensitive information to security risks, enabling unauthorized access, modifications, and data sharing without patients' consent. These challenges require a patient-centric, standardized approach to managing health data. This article presents a decentralized health information exchange framework that leverages blockchain technology to address these issues. The framework combines the Interplanetary File System for scalable data storage with Ethereum (ETH) smart contracts to enforce secure and transparent access control. By integrating these technologies, the proposed solution presented here enhances data security, transparency, and interoperability while reducing costs and reliance on intermediaries. Experiments conducted on the ETH blockchain demonstrate the framework's efficiency, with smart contracts evaluated for transaction costs and accuracy. In addition to examining scalability and security, the authors discuss the framework's limitations and its potential for broader application. To foster further research and collaboration, the source code for the smart contracts is openly available on GitHub.
