Enhancing Data Privacy in Healthcare Systems Using Blockchain Technology

Sri Bhargav Krishna Adusumilli, Harini Damancharla, Arun Raj Metta

Abstract


The increasing digitization of healthcare systems has led to concerns regarding data privacy, security, and unauthorized access. Traditional centralized systems are vulnerable to breaches, data tampering, and inefficiencies. Blockchain technology, with its decentralized, immutable, and transparent nature, offers a promising solution to address these challenges. This paper explores how blockchain can be leveraged to enhance data privacy in healthcare systems by ensuring secure data storage, access control, and interoperability. A blockchain-based framework is proposed to protect sensitive patient information while enabling secure sharing among authorized stakeholders. By incorporating cryptographic techniques and smart contracts, this solution ensures data integrity, reduces unauthorized access, and improves trust within healthcare ecosystems. The study also discusses potential challenges, such as scalability and integration, and outlines future research directions.
