Here’s the Merc story today about how a UC Berkeley computer science student figured out how to make audio recordings of keyboard strokes that deciphered which words were being typed.
She used a cheap microphone plugged into a laptop running generic speech recognition software. “It’s possible that intelligence agencies are using this method,” said her professor, “and it’s possible that some bad guys already have this.”
