Blockchain Applications in Healthcare: Ensuring Data Security and Patient Privacy

Abstract

Blockchain technology has emerged as a transformative solution for the healthcare sector, addressing critical challenges in data security, patient privacy, and interoperability. By leveraging decentralized and immutable ledgers, blockchain ensures that medical records remain secure, tamper-proof, and accessible only to authorized parties. This paper explores the applications of blockchain in healthcare, highlighting its role in safeguarding patient data, preventing fraud, reducing operational costs, and enabling efficient data sharing. Furthermore, it discusses current limitations, regulatory challenges, and future prospects for large-scale adoption.
