Secure sharing of spatio-temporal data through name-based access control
As more and more mobile data is collected continuously in space and time for a variety of purposes such as health monitoring and driving behavior tracking, people are increasingly concerned about their privacy when sharing their data. To minimize privacy leakage, data owners often want to restrict the access to their data based on space and time constraints while meeting each data user's specific needs. In this paper, we introduce an access control system over Named Data Networking (NDN) that allows data owners to schematize and control data access at a fine granularity with respect to time, space, and user needs. More specifically, we designed spatio-temporal access control policies using hierarchically structured names, extended Name-based Access Control to support spatio-temporal policies, and incorporated publish-subscribe functionality for real-time data sharing. Moreover, we developed an NDN-based prototype based on our design and evaluated its performance in sharing both real-time and historical data.
