(ISNS)—Using the microphones and speakers that come standard in many of today’s laptop computers and mobile devices, hackers can secretly transmit and receive data using high-frequency audio signals that are mostly inaudible to human ears, a new study shows.

Michael Hanspach and Michael Goetz, researchers at Germany’s Fraunhofer Institute for Communication, Information Processing, and Ergonomics, recently performed a proof-of-concept experiment that showed that "covert acoustical networking," a technique which had been hypothesized but considered improbable by most experts, is indeed possible.

Their findings, detailed in a recent issue of the Journal of Communications, could have major implications for electronic security.
