  The rapid growth of the Internet of Things technology in healthcare domain
led to the appearance of many security threats and risks. It became very
challenging to provide full protection with the expansion in using sensor
objects in medical field, this led to the Internet of Medical Things
definition, the security part in IoMT poses a perilous problem that keeps
growing, because of the data sensitivity and critical information. The lack of
providing a secure environment in IoMT may lead to patients privacy issues, not
only leaving the data privacy of the patients at risk but also their lives can
be in danger. In this paper, we provide a discussion on both definition and
architecture of the Internet of Medical Things and Propose a new authentication
approach through machine learning, to enhance the security level.
