Blockchain in Healthcare: A Systematic Review of Security, Privacy, and Data Integrity
Abstract
Blockchain technology has gained attention as a solution to security and privacy concerns in healthcare. This review examines the application of blockchain in electronic health records (EHR), drug supply chain management, and clinical research. The paper highlights the advantages of blockchain, including decentralized data storage, immutability, and enhanced security against cyber threats. Additionally, the challenges of scalability, interoperability, and regulatory acceptance are discussed. The review concludes with recommendations for overcoming these challenges to achieve widespread adoption of blockchain in healthcare.
