Role of trust in the ubiquitous healthcare system: Challenges and opportunities

Abstract Due to the rising incidence of lifestyle-related diseases and chronic illnesses, along with an aging population, a need for better healthcare systems has attracted the attention of researchers and medical practitioners across the globe. The processes of technical convergence strongly influence the development of data mining, the Internet of things (IoT), and embedded sensor networks in the field of health technology. A ubiquitous or smart healthcare system is the outcome of this convergence. Wearable embedded sensor systems are the future of healthcare; they allow for ubiquitous monitoring of health regardless of a person’s location. These sensors can monitor numerous parameters, including sleep, blood pressure, heart rate, and so on, and send the data remotely for analysis so that a suitable, effective treatment can be started if necessary. Such future systems require strong and promising technologies, which include miniaturization of sensors, embedded systems, secure wireless communication, and decision making based on the quality of data. This chapter focuses on secure, low-power technologies for smart healthcare, the challenges they present, and recommendations for future research.
