Abstract— Securing electronic health records (EHRs) is critical in modern healthcare to uphold patient privacy, data integrity, and public trust in health information systems. Existing EHR systems, while efficient, are susceptible to vulnerabilities such as data breaches, unauthorized access, and data tampering. This research proposes an enhancing EHR security by integrating blockchain technology. Blockchain, a decentralized and immutable ledger, offers a robust solution to address these challenges. By leveraging blockchain's key features – transparency, security, and data immutability – this study aims to develop a secure and tamper-proof EHR system that significantly minimizes the risk of data breaches and unauthorized modifications. Furthermore, Data Security are employed to automate and enforce access controls and consent management, further enhancing the security. This research comprehensively analyses the limitations of current EHR systems, emphasizing the critical need for improved security measures. It then investigates the feasibility of implementing a blockchain-based solution, considering both technical and operational aspects, including hardware and software requirements. The findings suggest that a blockchain-based EHR system can offer superior security and transparency compared to traditional approaches. By leveraging advanced decentralized storage, this system has the potential to significantly enhance patient data protection, streamline healthcare operations, and foster greater trust in electronic health records.
