6. Privacy and Security Concerns in IoT-Based Healthcare Systems

The Internet of Things (IoT) Healthcare system has become one of the most indispensable parts of human lives, and this has dramatically increased the medical information system that brings about big data. Healthcare practitioners are already adopting wearable devices based on the IoT to streamline the diagnosis, monitoring, prediction, and treatment process. The affordability and user-friendliness of the usage of IoT start revolutionizing healthcare services. Billions of sensors, devices, and vehicles in recent times have been connected through the Internet using IoT technologies. For continuous health tracking, wireless sensor networks can be implemented to enhance the well-being of patients, make the healthcare system more effective, and help respond quickly to emergencies. The IoT-based healthcare can be employed to enhance the well-being of patients, make the healthcare system more effective, and help respond quickly to emergencies. However, these systems also pose significant risks in terms of privacy and security issues surrounding data transfer, processing, monitoring, and documentation. Such healthcare data protection, security, and privacy concerns may result from a delay in the progress of treatment, diagnosis, and even endangering the life of the patient. Therefore, this chapter presents a summary of the IoT, comprising its architecture, and reveals the IoT-based healthcare application privacy and security concerns. The chapter also proposed a framework to secure healthcare information in the IoT environment. This will help to protect healthcare data on the IoT platform and meet the strict security and privacy needs of ubiquitous medical requests.
