Spoofing attacks are one of the security traits that biometric recognition systems are proventobevulnerable to. When spoofed, abiometric recognition system is bypassed by presenting ac opyo ft he biometric evidence of av alid user.A mong all biometric modalities, spoofing af ace recognition system is particularly easy to perform: all that is needed is(More)
Besides the recognition task, today's biometric systems need to cope with additional problem: spoofing attacks. Up to date, academic research considers spoofing as a binary classification problem: systems are trained to discriminate between real accesses and attacks. However, spoofing countermeasures are not designated to operate stand-alone, but as a part(More)
As a crucial security problem, anti-spoofing in biomet-rics, and particularly for the face modality, has achieved great progress in the recent years. Still, new threats arrive in form of better, more realistic and more sophisticated spoofing attacks. The objective of the 2nd Competition on Counter Measures to 2D Face Spoofing Attacks is to challenge(More)
—While more accurate and reliable than ever, the trustworthiness of biometric verification systems is compromised by the emergence of spoofing attacks. Responding to this threat, numerous research publications address isolated spoofing detection , resulting in efficient countermeasures for many biomet-ric modes. However, an important, but often overlooked(More)
With biometrics playing the role of a password which can not be replaced if stolen, the necessity of establishing countermeasures to biometric spoofing attacks has been recognized. Regardless of the biometric mode, the typical approach of anti-spoofing systems is to classify biometric evidence based on features discriminating between real accesses and(More)
