Lego Robots Crack Gesture-Based Security
An anonymous reader writes: Lego Robots outfitted with a "finger" made from molded Play-Doh were able to bypass seven different gesture-based security systems at least 70% of the time, according to a new study funded by DARPA. Gestural ID systems "tend to take a rosy view of the security world in which hackers attempt to breach such defenses via crude impersonation," reports Vice, which notes that the systems now turn out to be far less reliable against automated attacks using a careful "forgery" of a user's gestures. DARPA titled their report "Robotic Robbery on the Touch Screen," writing that it "demonstrates the threat that robots pose to touch-based authentication, and provides compelling evidence as to why the zero-effort attack should cease to be used as the benchmark for touch-based authentication systems."
