Ginger: An Access Control Framework for Telematics Applications

Telematics applications in automobiles have attracted considerable attention for their promise of value-added services. However, new challenges arise from the integration of telematics applications that require a multitude of vehicular data. The safety-critical context of the automotive domain calls for reliable access control mechanisms, especially when applications access sensitive data. However, those mechanisms must also respect the requirement of minimal driver distraction. To cope with these issues we propose Ginger - an access control framework for telematics applications. Ginger is context aware, provides enhanced privacy protection, and realizes advanced access control paradigms. We demonstrate Ginger´s feasibility with an Android-based implementation in a functional evaluation consisting of two representative use cases and in a comparative analysis with related approaches.
