These calculations mapped the route the person was traveling by matching phone data against public information. Once the person's activity was revealed, PinMe launched one of four additional algorithms targeted for each mode of transportation. The discovery could also be used for new ways to navigate - in self driving cars and ship navigation systems, for instance. It did this by gathering clues from a phone's sensors that exposed crucial information: how fast the person was moving and the direction of travel, how often the person was stopping and then moving again, and the person's altitude. The app then used a machine-learning algorithm that had been trained to recognize the difference between walking, driving, train-riding and flying. This narrowed down the search by exposing the phone's most recent location. PinMe first read each phone's latest IP address and network status to nail down its last Wi-Fi connection. The study subjects traveled by foot, car, train and airplane through cities including Philadelphia, Dallas and Princeton.

To run their experiment, the Princeton researchers collected phone data from three people for one day after installing PinMe on their phones - Galaxy S4 i9500, iPhone 6 and iPhone 6S - running either Android or iOS.

'I think a lot of follow-up should deal with how to prevent this attack,' he said. PinMe's developers already are working on ways for people to defend themselves against it, said Jha, whose research focus is on the security of the 'internet of things,' a phrase that describes the increasingly digital products that power our daily activities. Watson Research Center, said 'The attack is. Supriyo Chakraborty, a security researcher at the IBM Thomas J.

When computed along with publicly available maps and weather reports, this data can help identify if a person is traveling by foot, car, train or airplane, and chart their route of travel.Īll the while, the presence of the app can be virtually undetectable. The app analyses information already stored on smartphones that, unlike GPS, doesn't require permission for access. 'PinMe demonstrates how information from seemingly innocuous sensors can be exploited using machine-learning techniques to infer sensitive details about our lives,' said Prateek Mittal, assistant professor in Princeton's Department of Electrical Engineering and PinMe paper co-author. They say the apps shows a potential privacy flaw in phones. The app uses a series of algorithms that locate and track someone by processing information such as a phone's IP address and time zone, along with data from its sensors.Īmong other information, phone sensors collect compass details from a gyroscope, air pressure readings from a barometer, and accelerometer data. Scroll down for video Called PinMe, it mines information such as data from gyroscopes and accelerometers, to work out where the user is - even if they don't give the app access to location services.

The researchers behind the app have called for phone makers to include a new software switch to turn of all sensors to protect user's privacy.
