PRICON: Self-determined privacy in the connected car motivated by the privacy calculus model

The advent of connected vehicles has increased the rel-evance of privacy in cars. Thus, a system is required that increases transparency and helps passengers to control their privacy in a self-determined manner. Here, we derive an interface based on the privacy calculus model and prove the validity of the theory-driven de-sign approach in course of a usability test. Based on fourteen participants, we demonstrate an above-aver-age usability of the theory-driven design which incorpo-rates the visual comparison of functional benefits and privacy risks. Interviews reveal that users especially acknowledge this direct comparison and underscore the successful implementation of the privacy calculus model in a vehicular privacy user interface
