IoT-Blockchain in Remote Patient Monitoring
Faisal Bin Ashraf, Rezwana Reaz · The 5th International Conference on Future Networks & Distributed Systems · 2021
Internet of Things (IoT) and Blockchain technologies have been utilized heavily in diverse domains, including remote patient monitoring (RPM). Expeditious development of wearable IoT medical devices with a variety of functionality, real-time sensory data from patients can be provided and further processed. IoT data are centrally collected, processed, and stored. But this centralization may face different problems including single-point failure, data tampering, privacy issues, etc. Blockchain can address these problems using its decentralized architecture. Hence, the combination of IoT and blockchain is a plausible solution to design a smart RPM system. In this paper, we provide a systematic review of the existing literature that has integrated blockchain with IoT-based systems from the perspective of remote patient monitoring. We have also proposed comprehensive IoT-blockchain based RPM framework guideline that addresses all aspects of designing an RPM system. Our proposed framework addresses the challenges of IoT-blockchain based systems, fulfills the requirements of real-time remote patient monitoring systems, and integrates the best practices of the literature in the relevant domains.
