Smartphones define a trend towards increasing combination and integration of sensing capabilities with almost ubiquitous inter-connectivity. Resulting location-based services and context-aware applications will benefit users by adapting better to the user application needs. However, there is a lack of effective means for controlling privacy in such systems which will likely increase further with future ubiquitous computing systems. Territorial privacy is a concept that moves away from the information-centric view in traditional systems to a context-centric approach. In this paper, we define and model territorial privacy in the context of ubiquitous computing. We further discuss potential observers and disturbers in our model and provide an overview on how territorial privacy can be controlled in different environments, ranging from personal to public.
