Smartphone owners may want to think twice before placing their gadgets so close to their computer keyboards, lest they unwittingly give their passwords away. Researchers from Georgia Tech have found a way to use a smartphone accelerometer —a component that detects how the phone is tilted— to remotely decipher keyboard strokes. “We first tried our experiments with an iPhone 3GS, and the results were difficult to read. But then we tried an iPhone 4, which has an added gyroscope to clean up the accelerometer noise, and the results were much better. We believe that most smartphones made in the past two years are sophisticated enough to launch this attack,” said Patrick Traynor, assistant professor in Georgia Tech’s School of Computer Science, according to an article on TechJournal.
