Face recognition is a mainstream biometric authentication method. However, the
vulnerability to presentation attacks (aka spoofing) limits its usability in unsupervised …

This paper addresses the problem of face presentation attack detection using different
image modalities. In particular, the usage of short wave infrared (SWIR) imaging is …

Face anti-spoofing plays a vital role in security systems including face payment systems and
face recognition systems. Previous studies showed that live faces and presentation attacks …

This paper presents an approach to assess the perfusion of visible human tissue from RGB
video files. We propose metrics derived from remote photoplethysmography (rPPG) signals …

Towards the security threats brought by presented fake faces to face recognition systems,
many countermeasures have been presented to resist fake faces and achieved promising …

Detecting 3D mask attacks to a face recognition system is challenging. Although genuine
faces and 3D face masks show significantly different remote photoplethysmography (rPPG) …

This work focuses on detecting presentation attacks (PA) mounted using custom silicone
masks. Face recognition (FR) systems have been shown to be highly vulnerable to PAs …

To counteract spoofing attacks, the majority of recent approaches to face spoofing attack
detection formulate the problem as a binary classification task in which real data and attack …

Выполнен обзор современных зарубежных и российских научных работ, посвященных
активно развивающимся методам фотоплетизмографической визуализации (ФПГ …

Vulnerability against presentation attacks remains a challenging issue limiting the reliable
use of face recognition systems. Though several methods have been proposed in the …
