The Telltale Keypress

By on May 13, 2004

A scientist at a security symposium this week says he’s developed a technique for snooping keystrokes by listening to the sounds made by the keyboard.

Each key on computer keyboards, telephones and even ATM machines makes a unique sound as each key is depressed and released, according to a paper entitled “Keyboard Acoustic Emanations” presented Monday by IBM research scientist Dmitri Asonov.

All that is needed is about $200 worth of microphones and sound processing and PC neural networking software.

It’s always something, isn’t it?
