Computer security researchers have uncovered a novel fingerprint recognition technique, based on the sounds made by a finger on a touchscreen. If combined with malicious software, this could one day expose users to biometric data theft.
PrintListener is the term given to a new technique revealed by a team of researchers based in the US and China. It exploits the sound of finger friction on a touchscreen to extract the patterns of the corresponding fingerprint.
Uh-oh! Daily quota reached.
