$this->bbcode_second_pass_quote('', '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.
