CONF deFreitasPereira_ICB_2013/IDIAP Can face anti-spoofing countermeasures work in a real world scenario? de Freitas Pereira, Tiago Anjos, André De Martino, José Mario Marcel, Sébastien EXTERNAL http://publications.idiap.ch/attachments/papers/2013/deFreitasPereira_ICB_2013.pdf PUBLIC International Conference on Biometrics Madrid, Spain 2013 http://pypi.python.org/pypi/antispoofing.crossdatabase URL User authentication is an important step to protect in- formation and in this field face biometrics is advantageous. Face biometrics is natural, easy to use and less human-invasive. Unfortunately, recent work has revealed that face biometrics is vulnerable to spoofing attacks using low-tech equipments. This article assesses how well existing face anti-spoofing countermeasures can work in a more realistic condition. Experiments carried out with two freely available video databases (Replay Attack Database and CASIA Face Anti-Spoofing Database) show low generalization and possible database bias in the evaluated countermeasures. To generalize and deal with the diversity of attacks in a real world scenario we introduce two strategies that show promising results.
