Blockchain-driven Smart Healthcare System: Challenges, Technologies and Future Research

Healthcare service is one of the most important pillars of the existence of life on the planet. It requires frequent updates in its existing methodology; it can be in terms of resources, manpower and technology. Many researchers have proposed various types of technologies (i.e., Internet of Healthcare Things (IoHT)) and ways to enhance the capabilities of the healthcare services, which also contributed in the real world scenario. However, IoHT suffers from various security and privacy-related issues. Because of them, the sensitive healthcare data may be disclosed or altered in the unauthorized way. Therefore, we need some security scheme to secure the communication of IoHT. The security issues of IoHT can be resolved by the blockchain-driven mechanisms. In this paper, we discuss the issues and challenges of blockchain-driven smart healthcare system. We also provide the details of the “generic architecture of the blockchain-driven smart healthcare system”. We then provide the practical implementation of the presented system. After that, we provide the details of various tools and technologies of the smart healthcare system. Finally, the work is finished with some concluding remarks and future research directions, which should be handled by the researchers working in the smart healthcare domain.
