Achieving Guaranteed Anonymity in GPS Traces via Uncertainty-Aware Path Cloaking

  title={Achieving Guaranteed Anonymity in GPS Traces via Uncertainty-Aware Path Cloaking},
  author={Baik Hoh and Marco Gruteser and Hui Xiong and Ansaf Alrabady},
  journal={IEEE Transactions on Mobile Computing},
The integration of Global Positioning System (GPS) receivers and sensors into mobile devices has enabled collaborative sensing applications, which monitor the dynamics of environments through opportunistic collection of data from many users' devices. One example that motivates this paper is a probe-vehicle-based automotive traffic monitoring system, which estimates traffic congestion from GPS velocity measurements reported from many drivers. This paper considers the problem of achieving… CONTINUE READING
