Toward a Safe and Secure Medical Internet of Things

This paper describes why ‘‘device state’’ and ‘‘patient context’’ information are necessarycomponents of device models for safe interoperability. This paper includes a discussion of the importanceof describing the roles of devices with respect to interactions (including human user workflows involvingdevices, and device to device communication) within a system, particularly those intended for use at thepoint-of-care, and how this role information is communicated. In addition, it describes the importance ofclinical scenarios in creating device models for interoperable devices. INDEX TERMS Safety, interoperability, state, context.
