Researchers have proposed a new attack on fingerprint authentication technology that leverages the sound of a user’s finger swiping on a touchscreen to extract fingerprint patterns. The attack can successfully compromise a significant percentage of partial and complete fingerprints within a few attempts. This is the first work to utilize swiping sounds to gain fingerprint information, highlighting a potential vulnerability in biometric security systems. The research overcame several technical challenges to develop the attack, known as PrintListener, which demonstrates a high success rate in real-world scenarios. This poses a threat to the widely trusted biometric fingerprint security market expected to reach $100 billion by 2032.
