Today, healthcare encompasses a wide range of issues, including clinical care, laboratory analysis, and public health consciousness. In contrast, healthcare monitoring enables not only in-hospital service control, but it also 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 also enables patients to maintain contact with their healthcare providers, be compliant with treatment schedules, and improve their wellness process. Instead of that, and due to the lack of technology and doctors, people living in remote areas are without access to modern healthcare services. Real-time surveillance of the patient’s well being, environment, and treatment is critical in this case. IoT-based healthcare management is a keystone mobile health (mHealth) technology that provides constructive and preventive remote health interventions. This innovative application comes to fulfill the demands of growing individuals and the high medical costs. It interconnects accessible medical resources and deliver smart, secure, and affordable healthcare services.<br />The internet of things (IoT) is a kind of physical technology system, such as devices, buildings, and even more medical centers and hospitals, in which full access to patient information is guaranteed through the internet. Such emergent technologies are introduced to assist advancement in the healthcare modernization process, thanks to the arising developments in the internet and computing devices. The Healthcare framework is a patient resources-based system. It includes informational, audiovisual coordination, and the retrieval of medical records. The integration of IoT in healthcare monitoring systems is complicated because of the large amounts of data and the need for encryption protocols to protect people’s personal information from being leaked. Any malicious person’s intervention, on the other hand, that will expose and manipulate patient’s vital data in any way may have serious implications, even death.<br />To face the above mentioned issues and taking advantage of the emerging security and communication technologies, developing a secure and real-time healthcare monitoring system is a must. SDN’s unique control/data plane separation allows a very efficient and distant monitoring of the healthcare devices. On the other side, the blockchain technology preserves the full history of patient records as well as healthcare sensors sensed information securely and privately without any possibility of alteration. For this reason, combining different technologies such as SDN and Blockchain can be a solution with direct positive effect. So, an efficient and reliable Healthcare Monitoring System (HMS) is proposed to prevent any insider/outsider intruder from injecting data, falsifying data, violating patients’ privacy, or even launching a denial of service attack against the HMS. A first version that includes only the overall architecture was initially presented in. Yet, besides validating the proposed architecture through simulations, in this work called STHM, their also implemented a modular trust management solution based on the Blockchain technology and evaluated how the benefit is relying on this technology in the HMS context. their proposal boosts the considered priorities of trust management concerns.<br />The approach 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 HMS.<br />On the other hand, several patient-centered solutions focus on the Electronic Health Record (EHR) management which involves all patient-related information including the security and trust aspects of both data and body sensors .Moreover, the network and monitoring side is known to require less improvements compared to the patients side which can be a source of undesired situations, especially during pandemics such as<br />COVID-19 where most of the work should be done remotely to minimize the physical contact with the patients. That is why the main aim of this work is to provide a secure and trusted distant monitoring process of patients healthcare.<br />
