Hiding Your Signals: A Security Analysis of PPG-based Biometric Authentication
Lin Li, Chao Chen, Lei Pan +3
Recently, physiological signal-based biometric systems have received wide attention. Unlike traditional biometric features, physiological signals can not be easily compromised (usu…
Video is All You Need: Attacking PPG-based Biometric Authentication
Lin Li, Chao Chen, Lei Pan +2
Unobservable physiological signals enhance biometric authentication systems. Photoplethysmography (PPG) signals are convenient owning to its ease of measurement and are usually wel…
FAAG: Fast Adversarial Audio Generation through Interactive Attack Optimisation
Yuantian Miao, Chao Chen, Lei Pan +2
Automatic Speech Recognition services (ASRs) inherit deep neural networks' vulnerabilities like crafted adversarial examples. Existing methods often suffer from low efficiency beca…
A Survey of PPG's Application in Authentication
Lin Li, Chao Chen, Lei Pan +4
Biometric authentication prospered because of its convenient use and security. Early generations of biometric mechanisms suffer from spoofing attacks. Recently, unobservable physio…
