Presentation Attack Detection Using Time-of-Flight-Based rPPG and Depth Features

Year: 2025

Type: conference-paper

Abstract: With the rising importance of biometric authentication in numerous security applications it is critical to implement Presentation Attack Detection (PAD) techniques to protect against counterfeit biometrics. We evaluate a PAD-approach that uses 3D Time-of-Flight (ToF) cameras to perform heart rate measurements based on remote photoplethysmography (rPPG) for PAD. Compared to Red-Green-Blue (RGB)-camera based approaches, ToF technology provides advantages, including integration of 3D depth information, insensitivity to electronic displays and independence from ambient light and robustness against its influence. We introduce a Spectral pulse Peak prominence Ratio (SPR) and motion based metric and evaluate their applicability to PAD and present first promising results.
