The Marauder

The Marauder Map is a magical map in J. K. Rowlingís fantasy series, ìHarry Potter and the Prisoner of Azkabanî. When being used by wizards who ìsolemnly swear that I am up to no goodî, it shows all moving objects within the boundary of the Hogwarts School of Witchcraft and Wizardry. In this talk, we introduce a similar attack to location privacy in wireless networks. Our system, namely the digital Marauderís map, can reveal the locations of WiFi-enabled mobile devices within the coverage area of a single high-gain antenna. The digital Marauderís map is built solely with off-the shelf wireless equipments, and features a mobile design that can be quickly deployed to a new location and instantly used without training. We present a comprehensive set of experimental results and some theoretical analysis which demonstrate the coverage and localization accuracy of the digital Marauderís map. We will also discuss countermeasures to this type of attack.
