Network and Distributed System Security (NDSS) Symposium 2024 · Day 3 · Physical Attacks
Fingerprint authentication has become an indispensable part of modern life, securing everything from smartphones and online payments to national ID systems. However, its pervasive use also introduces significant security challenges, particularly concerning the leakage of biometric data. This talk introduces **PrintListener**, a groundbreaking side-channel attack that exploits a previously overlooked vulnerability: the subtle sounds generated by fingers swiping across device screens. Unlike traditional fingerprint attacks that require physical contact or visual access, PrintListener operates contactlessly, inferring crucial fingerprint pattern features from ambient audio.
