Keystoke Recognition Uses Wi-Fi Signals to Snoop (Threat Post)


A group of academic researchers have figured out how to use off-the-shelf computer equipment and a standard Wi-Fi connection to sniff out keystrokes coming from someone typing on a keyboard nearby.

The keystroke recognition technology, called WiKey, isn’t perfect, but is impressive with a reported 97.5 percent accuracy under a controlled environment. WiKey is similar to other types of motion and gesture detection technologies such as Intel’s RealSense. But what makes WiKey unique is that instead of recognizing hand gestures and body movement, it can pick up micro-movements as small as keystrokes.
