Motivated by connected vehicle applications such as automotive traffic monitoring systems, this talk will provide an overview of the problem of providing location privacy by depersonalizing wireless communications. I will first focus on depersonalizing application-layer location data. This part of the talk will review spatial cloaking for point queries and discuss path cloaking techniques for providing unlinkability in time-series location traces. I will then describe how we incorporated such ideas, as a privacy-by-design case study, in a smartphone-based automotive traffic monitoring system that has been trialed with hundreds of users in the Bay Area. This effort led to a distributed scheme based on virtual trip lines, which does not need to rely on a trustworthy privacy server with access to all traces. In the latter part of this talk, I will discuss location privacy considerations across lower layers of the wireless network stack and shed light on the current state-of-the art with a case study analysis of wireless transmitters embedded in automobiles.
