Scientists use sensors to eavesdrop on phone calls remotely

Researchers have demonstrated a method to detect the vibrations of a mobile phone's earpiece and decipher what the person on the other side of the call was saying with up to 83 percent accuracy.

The team at Pennsylvania State University used an off-the-shelf automotive radar sensor and a novel processing approach to reveal this significant security concern.
