Spoofing attack can easily deceive face recognition system. In this paper, we explore the
issue of face anti-spoofing with good performance in accuracy by utilizing optical flow vector …

The subject is a challenge response mechanism used as an optional add-on to the face
recognition part of the multi modal biometric authentication system" BioID". This mechanism …

Personal identity verification based on biometrics has received increasing attention since it
allows reliable authentication through intrinsic characteristics, such as face, voice, iris …

Face recognition provides many advantages compared with other available biometrics, but it
is particularly subject to spoofing. The most accurate methods in literature addressing this …

Currently, reliable face detection and recognition are becoming more important on mobile
devices--eg to unlock the screen. However, using only frontal face images for authentication …

Leveraging built-in cameras on smartphones and tablets, face authentication provides an
attractive alternative of legacy passwords due to its memory-less authentication process …

The face recognition community has finally started paying more attention to the long-
neglected problem of spoofing attacks. The number of countermeasures is gradually …

It is a common spoof to use a photograph to fool face recognition algorithm. In light of
differences in optical flow fields generated by movements of two-dimensional planes and …

Spoofing with photograph or video is one of the most common manner to circumvent a face
recognition system. In this paper, we present a real-time and non-intrusive method to …

There are several types of spoofing attacks to face recognition systems such as photograph,
video or mask attacks. Recent studies show that face recognition systems are vulnerable to …
