Securing Health Data with Blockchain

With the rapid digitization of healthcare systems, electronic health record (EHR) management has become crucial for efficient healthcare delivery. Traditional EHR systems face challenges related to security, interoperability, and trustworthiness of data. Blockchain technology offers a promising solution to address these challenges by providing a decentralized and immutable platform for EHR system. This survey paper explores the landscape of blockchain-based EHR systems, examining various approaches, architectures, and applications in the healthcare domain. Key areas of examination include the secure storage of EHRs on blockchain, ensuring integrity of the data and confidentiality while granting patients greater dominance over their health information. The paper discusses the integration of blockchain with EHR systems, exploring different consensus mechanisms, data models, and encryption techniques used to ensure the integrity and privacy of patient records.
