A Survey on the Security of Health Data Captured Using IoT Devices Using Cloud and Fog Computing

Abstract

Thanks to a new technology known as the Embedded System and the Internet of Things (IoT), smart gadgets become the fundamental building blocks for developing smart ubiquitous frameworks. Health monitoring and day-to-day challenges are two of the primary issues that directly affect life quality. The Internet of Things may find its most significant application in healthcare technology. To fully realize the benefits of IoT in the healthcare industry, numerous challenging research and efforts still need to be completed, even though multiple studies have been produced for the IoT healthcare sector. This literature review examines current advancements in Internet of Things (IoT)-based health care, focusing on cloud management, evolutionary computing, network and communication techniques, system design and architecture, e-health and m-health, and privacy and security measures. Blockchain and IoT technology may be used to construct decentralized Internet of Things-based electronic healthcare systems. This makes two-way, real-time communication between physicians and end users possible. They proposed an encrypted security solution that starts with Internet of Things sensors. This solution ensures that packets containing the patient's health-related data are encrypted before being transferred using an algorithm based on the encryption approach inside the sensor device. Devices in the healthcare sector may now safeguard user privacy by utilizing a privacy-aware offloading technique based on reinforcement learning (RL), as evidenced by Internet of Things (IoT) devices. Blockchain and IoT technologies may be practical for creating decentralized Internet of Things-based electronic healthcare systems. The ability to communicate back and forth in real time between doctors and end users is made feasible by this.
