Abstract
Healthcare has undergone a rapid shift from traditional to smart health care system in recent times. The new paradigm takes a patient-centered approach and offers a variety of benefits to patients. Rapid technological developments have allowed for such a quick shift. The Internet of medical things (IoMT) is a key component of the development of smart health care systems. The current pandemic situation has demonstrated that IoMT systems can provide a quick patient diagnosis by continually monitoring their health and perhaps saving lives in the event of an emergency. But most IoMT devices were not built with security in mind, making them vulnerable to cyber-attacks. Furthermore, many gadgets such as smart sensors, wearable devices, handheld devices, and a variety of other heterogeneous devices being connected in a network for the smooth running of communication in healthcare make this system more vulnerable to security and privacy attacks. Security of IoMT devices and data is of paramount importance and critical to protecting the lives of patients. This survey attempts to explore applications of various recent technologies, particularly blockchain, PUFs, and AI/ML, in terms of security, privacy, protection, integrity, and authentication in IoMT ecosystem. In addition, insights into the benefits and limitations of existing security and privacy solutions have been provided.
