PinMe: tracking a smartphone with localization services turned off

Arsalan Mosenia, Xiaoliang Dai, Prateek Mittal and Niraj Jha, in paper recently published, describe a new user-location mechanism that exploits non-sensory/sensory data stored on the smartphone to estimate the user’s location when all location services are turned off. The technique, tested on iPhone 6, iPhone 6S and Galaxy S4, is dubbed “PinMe“.
