This research article delves into the synergistic integration of the Internet of Things (IoT), blockchain, and fog computing to bolster the security of healthcare systems. With the ever-growing pressure on healthcare infrastructure and the inherent vulnerabilities of connected medical devices, robust security measures are paramount. This study goes beyond just security, exploring how this technological triumvirate can optimize overall healthcare operations through enhanced efficiency and improved effectiveness. By analyzing existing research and real-world case studies, the paper sheds light on the specific vulnerabilities plaguing IoMT devices. It then explores the potential of fog computing for localized processing, enabling faster response times and reduced reliance on centralized cloud resources. Finally, the paper examines how blockchain technology can revolutionize healthcare data security by offering a tamper-proof, immutable ledger system. Ultimately, this research aims to demonstrate the transformative potential of these combined technologies in creating a more secure, efficient, and effective healthcare delivery landscape. However, the understanding of the alignment of these technologies with the existing regulations (e.g., The Health Insurance Portability and Accountability Act (HIPAA) in the U.S.) is the main challenge for practical application in this study. Additionally, the sustainability of such systems includes aspects like maintenance and updates.
