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 …

In this paper, a local spatiotemporal descriptor, namely, the volume local binary count
(VLBC), is proposed for the representation and recognition of dynamic texture. This …

Nowadays, face biometric based access control systems are becoming ubiquitous in our
daily life while they are still vulnerable to spoofing attacks. So developing robust and reliable …

Face anti-spoofing is very significant to the security of face recognition. Many existing
literatures focus on the study of photo attack. For the video attack, however, the related …

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 …

The creation of manipulated multimedia content involving human characters has reached in
the last years unprecedented realism, calling for automated techniques to expose …

The growing use of control access systems based on face recognition shed light over the
need for even more accurate systems to detect face spoofing attacks. In this paper, an …

Aiming to counter presentation attack (also known as spoofing attack) in face recognition
system, a face presentation attack detection (also known as spoofing detection or liveness …

Biometrics has been increasingly used as the well-known technology for the identification
and verification of a person. Among the different biometric traits, the face has been …

Face presentation attacks are the main threats to face recognition systems, and many
presentation attack detection (PAD) methods have been proposed in recent years. Although …
