The Security Risk of Keyboard Clicks

Posted by simoniker on from the tap-tap-oops dept.

Gudlyf writes "First the blinking LED security issue, now this: listening to tell-tale keyboard clicks to decipher from afar what a person is typing. This isn't limited to just computer keyboards -- ATM's, telephone keypads, security doors, etc. Apparently with $200 worth of sound equipment and software, these keyboard clicks can be translated to within 80% accuracy. Of course, a whole lot of this is just theory."

    Of course, in theory:

    - the earth is spherical in shape
    - the earth revolves around the sun

    Former theories, now proven beyond a shadow of a doubt.

    - we evolved from lower species

    Pure conjecture, with no evidence. Yes, a theory, about as sound as the theory of UFOs abducting people.

    - energy equals mass times the speed of light squared

    This is the only one I would consider a legitimate theory... It was not just a wild guess when it was created, and modern evidence suggests that it may in fact be correct, or close to it.

    To be pedantic, the Earth is an oblate spheroid, not a sphere. This becomes important when you use things like GPS.
