ABSTRACT

Transparency, auditability, trustworthiness, privacy, and security are some of the issues plaguing existing healthcare data management systems. Other concerns include data origin tracing, immutability, traceability, and auditability. In addition, many of the healthcare data management systems in use today are centralized, which increases the risk of a single point of failure and makes them susceptible to natural disasters. The emerging decentralized technology known as blockchain has the potential to completely revamp, transform, and change the way healthcare organizations handle patient data. This article offers a comprehensive overview of blockchain architecture, platforms, and classifications to assist in the selection of the most suitable blockchain platform for healthcare applications. This compilation presents the latest discoveries from state-of-the-art research on healthcare blockchain and current healthcare applications that are based on blockchain technology. Furthermore, to provide insight into future research, we present the challenges and prospective areas of study. We utilized threat model classifications to analyze the various security attacks on the blockchain protocol and conducted a comparative analysis of detection and prevention techniques. In addition, this paper also covers techniques to enhance the privacy and security of the blockchain network.
