Blockchain technology presents significant opportunities for improving data security, privacy, and user control across various sectors, including healthcare. Traditional Electronic Health Record (EHR) systems often struggle with unauthorized access, limited interoperability, and a lack of patient control over sensitive data. This project proposes a blockchain-based EHR system to overcome these challenges by placing the patient at the center of data management. The proposed system allows patients to upload, manage, and share their medical records while granting or revoking access as needed. It employs Solidity smart contracts for secure access control, MetaMask for authentication, Ganache and Truffle for testing, and off-chain storage using IPFS via Pinata. The front end is developed in ReactJS to ensure a seamless and intuitive experience. By storing only critical metadata on-chain and maintaining full records off-chain, the system addresses scalability and efficiency issues. This solution enhances privacy, ensures secure sharing, and empowers patients with ownership of their healthcare data.
