A team of researchers has discovered a way to log keystrokes from computers simply by placing an iPhone 4 near a user's keyboard and monitoring the keyboard's vibrations.
The team at Georgia Tech used the accelerometer in an iPhone 4 to sense keyboard vibrations and determine what was being typed, without any connectivity to the user's computer or peripherals.
As documented in their paper, (sp)iPhone: Decoding Vibrations From Nearby Keyboards Using Mobile Phone Accelerometers, the researchers could decipher complete sentences with up to 80 percent accuracy, using a dictionary of about 58,000 words.
