An Electronic Health Record (EHR) represents a digital rendition of a patient's complete medical history, meticulously maintained by healthcare providers. The sharing of EHRs plays a pivotal role in healthcare, facilitating seamless communication among different medical institutions. However, the prevalent use of cloud-based EHR sharing systems raises concerns regarding patient privacy and data security. The centralization of data in cloud servers can potentially expose sensitive information to vulnerabilities. Blockchain technology emerges as a promising solution to address these challenges, owing to its distinctive attributes of decentralization and tamper resistance. This paper advocates for the adoption of Blockchain-Based Privacy and Access Control to enhance EHR security. The primary objective of this proposal is to implement blockchain technology for EHRs, ensuring the secure storage of electronic records while precisely defining access permissions for authorized users.
To achieve this, we employ a Hybrid Encryption approach, combining Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC) techniques for sharing medical records securely. Additionally, we model the relationships between EHR owners and EHR users using smart contracts, which operate within the Ethereum blockchain ecosystem. These smart contracts facilitate the enforcement of access control policies, ensuring that only authorized individuals can access and modify EHR data. Our evaluation of the proposed system centers on the efficiency of encryption and decryption processes, measuring the time required to safeguard and retrieve EHR data. By integrating blockchain technology, we aim to establish a robust and secure framework for managing electronic health records, safeguarding patient privacy, and enhancing data security in the healthcare sector.
