A study conducted at the University of Massachusetts Lowell shows that Google Glass and other wearables can pick up four-digit PINs typed onto an iPad from 10 feet away. A special software designed for the study allows PINs to be stolen even if Glass is not facing the screen of the iPad. Xinwen Fu, a computer science professor at the university, tells Wired:
Any camera works, but you can’t hold your iPhone over someone to do this. Because Glass is on your head, it’s perfect for this kind of sneaky attack.
