Researchers from the University of Illinois have discovered that motion sensors used in mobile phones and tablets have a unique “fingerprint“ due to imperfections in their manufacturing. Any app installed on a device can identify the device on the basis of the reaction of the motion sensors without using cookies and without access to the device ID. This method allowed the researchers to identify the device with 96% success rate.
