iPhone keylogger can log your desktop typing

Get into the office, sit down at the computer and lay your cellphone on the desk – a every day ritual that millions do every morning, but you cant imagine what can it lead to . Security researchers have discovered they can detect the vibrations caused by using a computer keyboard and read off what is being typed simply by placing a smartphone with a keylogging app on the desk nearby.
Patrick Traynor and colleagues at the Georgia Institute of Technology in Atlanta were able to use the motion sensors inside an iPhone to read keystrokes from a keyboard 5 centimetres away with up to 80 per cent accuracy.
The sensors don't recognise the vibrations of particular individual keys, but for consecutive pairs of keystrokes they can tell whether the keys are on the left or right of the keyboard and how close together they are. This information is then matched to a dictionary to recreate the typed word. For example, the word "canoe" breaks down into four pairs: "CA", "AN", "NO" and "OE". The first pair is classified as left-left-near, the second is left-right-far, and so on.
Though it will not reveal your information like desktop keylogger's but it can give the fill in the blank information to the intruders through which they can get the desired information by simple guesses .
