Blockchain-Driven Non-Repudiation and Secure Framework for Healthcare Data Management

The healthcare industry has experienced remarkable growth in data generation and revenue, making it the most rapidly expanding sector. To enhance security measures, our study explores the adoption of blockchain technology, leveraging its various aspects such as decentralization, consortiums, Ethereum, and Hyperledger. This paper proposes a Secured Healthcare Framework utilizing blockchain technology, with a focus on securing Electronic Health Records (EHR) through smart contracts. This approach ensures end-to-end security and non-repudiation. By integrating IoT devices such as RFID and Arduino, our method not only enhances security but also stream-lines data management within healthcare settings. The results demonstrate significant efficacy in the secure transmission and management of patient medical records. Moreover, experimental findings indicate an 89.88 % difference in latency between the MetaMask and Ganache environments, and a 13.04 % difference in gas usage for transactions in the Remix and Ganache environments. These findings highlight the potential of our proposed framework to improve security and efficiency in healthcare data management.
