![]() ![]() ![]() Since the sources that produce this data don't require user permission to operate and only collect a small amount of data, the method is "virtually undetectable," the release said. When mixed with public information like maps, a device's location can be estimated without location services. The technique, called PinMe, shows it is possible to track a location even if the location services, GPS, and Wi-Fi are turned off.ĭata used to track the device include the phone's time zone and information from its sensors, like air pressure, a Princeton press release said. The team-Arsalan Mosenia, Xiaoliang Dai, Prateek Mittal, and Niraj Jha-combined information from phone-based and non-phone sources to determine a device's location. PinMe app analyses data from sensors such as gyroscopes and accelerometers Was analysed alongside publicly available maps and weather reports Could pinpoint where people were - and how they were. Smartphones can still be tracked even if location services and GPS are turned off, according to Princeton University researchers. Turning off location service might not be the most appropriate way of dealing with spying or tracking, but it helps to reduce the risk.
