A new security vulnerability has been discovered: the clickety clack of the keyboard.

An audio recording of an individual’s typing can be transposed into a transcript of what was typed, according to researchers with the University of California, Berkeley. The technique works because each key makes a distinct sound when hit, and users, who typically type about 300 characters a minute, leave enough time between keystrokes for a computer to isolate the individual sounds.

I thought I could sort of hear different sounds for each key, I thought it was just my ears.

At least I know I’m not crazy smile

I guess you know when someone is trying to hack your computer this way when you find an unfamiliar looking microphone sitting next to your keyboard.

Wouldn’t it just be easier to install a key logger?

The problem is that you’d have to get a large sampling of sounds before you could assign sounds to specific keys.  Of course, this also assumes that each key really does have a different sound that isn’t influenced by speed or heaviness of typing.  I know that my typing style varies wildly throughout the day.  Sometimes I key harder, sometimes softer, and sometimes miss the correct keys altogether.

Hmm…that would have a huge dependence on the individual keyboard and typer though, don’t you think?  I mean, there may be different sounds of me typing, or of, say stephen typing.  also, our keyboards are probably different.  Like Charybdis says, you’d have to get a huge sample of the individual typing on their keyboard before it would even be useful.

I wonder if you have to use the home row keys for it to work? 

Also, I have to add, that I HATE HATE HATE the sound of “fake” typing, like in a commercial, or in a movie.  When the people type it’s just so…annoying.  I don’t mind listening to the people next to and around me type…it’s just the click click tap of fake typing that makes me crazy.

And why do programmes like CSI have beeping keyboards? Imagine how annoying it would actually be if every character you typed was followed by a little beep? Bah!
