Criticism of Google Glass has often focused on the way its camera makes surreptitious video recording too easy. Now researchers have shown that footage captured by the face-mounted camera could also pose a security threat.Software developed by the researchers can automatically recover the passcodes of people recorded on video as they type in their credentials, even when the screen itself is not visible to the camera. The attack works by watching the movement of the fingers to work out what keys they are touching. It also works on footage from camcorders, webcams, and smartphones, but Glass offers perhaps the subtlest way to stage it. The work suggests that “shoulder surfing”—stealing passwords or other data by watching someone at a computer—could become more of a threat as digital cameras and powerful image processing software become more common.
