Those seemingly random noises, when processed by a computer, were translated with up to 96% accuracy."It's a form of acoustical spying that should raise red flags among computer security and privacy experts," said Doug Tygar, a Berkeley computer science professor and the study's principal investigator.
Researchers used several 10-minute audio recordings of people typing away at their keyboards. They fed the recordings into a computer that used an algorithm to detect subtle differences in the sound as each letter is struck.
