The ENTOURAGE Privacy and Security Reference Architecture for Internet of Things Ecosystems

The Internet of Things (IoT), with its ubiquitous sensors and actuators, enables highly useful novel use cases, notably in the field of digital assistance. It also raises unprecedented privacy and security issues. This contribution presents a reference architecture for an ecosystem of digital assistants with minimal barriers of entry, that aims to be both secure and privacy-respecting. We present concise definitions, requirements, and a layered architectural structure for IoT assistants. Moreover, we introduce privacy and security assistants building on privacy patterns such as privacy dashboard, privacy mode and security and privacy policies and interface.
