In healthcare in particular, the use of IoT concepts and technologies make diagnose and monitor more convenient for the physicians and patients. As mobile applications solutions are widely accepted because the easy to use, secure healthcare service is a new demand for mobile solutions. To protect the privacy and security for patients in the domain of healthcare towards IoT, a systematic mechanism is needed. This article proposes a novel security and privacy mechanism for Health Internet of Things (Health-IoT) to solve above problems. Health-IoT is promising for both traditional healthcare industry and the information and communication technologies (ICTs) industry. From the view of trustworthiness, interactive vector was proposed to communicate the end-devices and application brokers.
