Princeton researchers demonstrated 'PinMe,' a technique that reconstructs smartphone user location trajectories with GPS-like accuracy by combining low-power sensor measurements (accelerometer, gyroscope, barometer, magnetometer) and non-sensory metadata (time zone, elevation maps), enabling tracking even when GPS and WiFi are turned off; the team validated the approach on iPhone and Android devices across activities (driving, train, plane, walking) and warns of significant privacy risks for mobile and IoT users.
