The Internet of Things (IoT) presents numerous benefits to consumers and has the potential to change the ways that consumers interact with technology in fundamental ways. Protecting consumer privacy becomes increasingly difficult as the IoT becomes more prevalent. More devices are connected to different types of devices, and this increase in connectivity and data collection results in less control. Privacy will loom the largest for many IoT systems and services because it is a form of regulation that cuts across many industries and IoT-use cases. In, the traditional privacy mechanisms are divided into two categories: discretionary access and limited access. The trust concept is used in various contexts and with different meanings. Trust is a complex notion about which no definitive consensus exists in the scientific literature, although its importance is widely recognized. Research efforts are also required to face the integration of IoT and communication technologies in a secure middleware, able to cope with the defined protection constraints.
