Google Glass can steal phone PINs from across a room
Researchers at the University of Massachusetts Lowell have demonstrated an interesting (and slightly scary) technique for using Google Glass to detect phone PINs with 83 percent accuracy from across a room – even when the screen wasn’t visible.
The technique used applies an image-recognition algorithm that doesn’t need direct sight of the screen. Instead, it uses a reference image of the target device to detect the angle at which it’s being held, then tracks the shadows from finger taps to detect which on-screen keys are being pressed …
