Face Biometric Spoof Detection Method Using a Remote Photoplethysmography Signal [PDF]
Sensors, 2022 Spoofing attacks in face recognition systems are easy because faces are always exposed. Various remote photoplethysmography-based methods to detect face spoofing have been developed. However, they are vulnerable to replay attacks.

Pulse Rate Variability Analysis Using Remote Photoplethysmography Signals [PDF]
Sensors, 2021 Pulse rate variability (PRV) refers to the change in the interval between pulses in the blood volume pulse (BVP) signal acquired using photoplethysmography (PPG). PRV is an indicator of the health status of an individual’s autonomic nervous system.
