Differential privacy in intelligent transportation systems

open access: yesProceedings of the sixth ACM conference on Security and privacy in wireless and mobile networks, 2013
In this paper, we investigate how the concept of differential privacy can be applied to Intelligent Transportation Systems (ITS), focusing on protection of Floating Car Data (FCD) stored and processed in central Traffic Data Centers (TDC). We illustrate an integration of differential privacy with privacy policy languages and policy-enforcement ...
