Hackers may have a new way of obtaining your biometric data – by secretly listening in to the sound of your finger swiping on your smartphone.
A team of scientists from China and the United States say they have devised a side-channel attack on minutiae-based automatic fingerprint identification systems (AFISs) which allows them to extract fingerprint patterns from the sound of friction produced by swiping on a touchscreen. Side channel attacks exploit information that is inadvertently leaked by a system.
