Technology Researchers recover typed text using audio recording of keystrokes

A new security threat revealed by computer scientists at the University of California, Berkeley, may be enough to drive some people away from their computer keyboards and back to pen and paper. The researchers show that a simple audio recording of those keyboard clicks can betray the text you just entered, from passwords to secret love notes.

Acoustical spying" using an audio recording of the sounds generated by typing on a computer keyboard is a potential security threat identified by UC Berkeley researchers.

The researchers were able to take several 10-minute sound recordings of users typing at a keyboard, feed the audio into a computer, and use an algorithm to recover up to 96 percent of the characters entered.

"It's a form of acoustical spying that should raise red flags among computer security and privacy experts," said Doug Tygar, UC Berkeley professor of computer science and information management and principal investigator of the study. "If we were able to figure this out, it's likely that people with less honorable intentions can - or have - as well."

Well, fortunately you have to be really important or work at an office to have that kind of thing done. My Dad and I prefer to stay at home to work

(And if at home I'll be safe until someone figures out how to rig an Ipod to record and decode my keyboard messages >_>)
