IoT in Context: Discovering Privacy Norms with Scalable Surveys

This survey method uses (1) a formal theory of privacy called contextual integrity and (2) combinatorial testing at scale to discover privacy norms. In our work, we have applied the method to better understand norms concerning data collection in smart homes. The general method, however, can be adapted to arbitrary contexts with varying actors, information types, and communication conditions, paving the way for future studies informing the design of emerging technologies. The technique can provide meaningful insights about privacy norms for manufacturers, regulators, researchers and other stakeholders.  Our paper describing this research appears in the Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies.
