Computer scientists at the University of California, Berkeley, have uncovered a new security Security, strength, a lower TCO: find out about all the advantages of IBM Middleware on Linux. threat: a simple audio recording of keyboard clicks could betray the text you just entered, from passwords to secret love notes.
They are calling it “acoustical spying.” 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.

This is old news but still interesting. I’m suprised you hadn’t heard about it earlier.
It’s sort of wierd how it works because it uses the users typing habits like time between each key and the pressure that occurs. An example is that we press j with a different strike then h, even if it were the same finger.
Ya, I haven’t been keeping up with much news / blogs / podcasts, etc. lately; I just see stuff every once in a while that catches my eye.
Coool! I want one! I can “listen” to my friend at work when she’s on e-Harmony.
