Securing Patient Medical Records with Blockchain Technology in Cloud-based Healthcare Systems

Blockchain technology presents a promising solution to myriad challenges pervasive in the healthcare domain, particularly concerning the secure and efficient management of burgeoning health information technology (HIT) data. This paper delineates a novel blockchain-based approach to enhance various aspects of healthcare management, including data accuracy, drug prescriptions, pregnancy data, supply chain management, electronic health record (EHR) management, and risk data management, with a special emphasis on ensuring secure access, immutable record-keeping, and robust data sharing. We propose a solution focusing on leveraging blockchain technology, particularly utilizing a Hyperledger network within Amazon Web Services (AWS), to securely manage patients' medical records in the cloud. The implemented framework, housed within a Virtual Private Cloud (Amazon VPC) to ensure restricted access and cost-effective resource utilization, underscores advancements in data availability, security, traceability, and sharing, addressing key challenges within healthcare data management, and presenting a scalable, efficient, and secure approach to EHR management in contemporary healthcare contexts.
