Abstract
Healthcare professionals and scholars have emphasized the need for IoT-based remote health monitoring services to track the health of the elderly. Such systems produce a large amount of data, necessitating the security and privacy of that data. On the other hand, Software Defined Networking (SDN) integration could be seen as a good solution to guarantee both flexibility and efficiency of the network which is even more important in the case of healthcare monitoring. Furthermore, Blockchain has recently been proposed as a game-changing tool that can be integrated into the Internet of Things (IoT) to have the optimal level of security and privacy. However, incorporating Blockchain into IoT networks, which rely heavily on patients’ health sensors, is extremely difficult. In this paper, a secure Healthcare Monitoring System (HMS) is proposed with a focus on trust management issues. The architecture seeks to protect multiple healthcare monitoring system components and preserves patient privacy by developing a security interface where separate security modules can be integrated to run side by side to ensure reliable HMS. The security framework architecture we propose takes advantage of the blockchain technology as a secure and timely information back-end. STHM is a proposal that uses Software-Defined Networking (SDN) as the communication medium that allows users to access SDN’s different functional and security technologies and services. Simulation results show that the use of Blockchain for the SDN-based healthcare monitoring can ensure the desired flexibility and security for a very lightweight additional overhead.
Highlights
Today, healthcare encompasses a wide range of issues, including clinical care, laboratory analysis, and public health consciousness [1]
The approach we propose aims at protecting various healthcare monitoring system components while still protecting patient privacy by constructing a secure environment in which separate security modules will coexist to ensure a consistent Healthcare Monitoring System (HMS)
In our previous work [5], we studied the main concerns of the Healthcare Monitoring System (HMS) security and privacy
Summary
Healthcare encompasses a wide range of issues, including clinical care, laboratory analysis, and public health consciousness [1]. Healthcare monitoring enables in-hospital service control, but it helps service providers to serve people outside the hospital, to properly track patient health outcomes, continue to provide high-quality services and to detect at-risk individuals. It enables patients to maintain contact with their healthcare providers, be compliant with treatment schedules, and improve their wellness process. Due to the lack of technology and doctors, people living in remote areas are without access to modern healthcare services. IoT-based healthcare management is a keystone mobile health (mHealth) technology that provides constructive and preventive remote health interventions [2]. This innovative application comes to fulfill the demands of growing individuals and the high medical costs
