Traditional Keyboard Sounds Can Be Decoded, Compromising Privacy

If you type on your desktop or laptop computer's keyboard while participating in a Skype call, you could be vulnerable to electronic eavesdropping, according to researchers at the University of California, Irvine and in Italy.

In a new study published online at arXiv, they describe a security breach whereby keystroke sounds, or acoustic emanations, can be recorded during a Skype voice or video call and later reassembled as text.

"Skype is used by a huge number of people worldwide," said co-author Gene Tsudik, Chancellor's Professor of computer science at UCI. "We have shown that during a Skype video or audio conference, your keystrokes are subject to recording and analysis by your call partners. They can learn exactly what you type, including confidential information such as passwords and other very personal stuff."

He specified that such an attack is not possible with touch-screen or holographic keyboards and keypads. And since data transfer over Skype is encrypted, it's extremely difficult for someone who's not part of a call to pilfer keystrokes. However, he outlined scenarios in which this cybersecurity threat could be all too real.
