Conversations remotely detected from cell phone vibrations, researchers report
UNIVERSITY PARK, Pa. — An emerging form of surveillance, “wireless-tapping,” explores the possibility of remotely deciphering conversations from the tiny vibrations produced by a cell phone’s earpiece. With the goal of protecting users’ privacy from potential bad actors, a team of computer science researchers at Penn State demonstrated that transcriptions of phone calls can be generated from radar measurements taken up to three meters, or about 10 feet, from a phone.
