User authentication is an important step to protect information, and in this context, face biometrics is potentially advantageous. Face biometrics is natural, intuitive, easy to use, and less human-invasive. Unfortunately, recent work has revealed that face biometrics is vulnerable to spoofing attacks using cheap low-tech equipment. This paper introduces a novel and appealing approach to detect face spoofing using the spatiotemporal (dynamic texture) extensions of the highly popular local binary pattern operator. The key idea of the approach is to learn and detect the structure and the dynamics of the facial micro-textures that characterise real faces but not fake ones. We evaluated the approach with two publicly available databases (Replay-Attack Database and CASIA Face Anti-Spoofing Database). The results show that our approach performs better than state-of-the-art techniques following the provided evaluation protocols of each database. © 2014 Pereira et al.; licensee Springer.2014 Flynn, P., Jain, A., Ross, A., (2008) Handbook of Biometrics, , Springer Science+Business Media, LLC, New York, USALi, S., Jain, A., (2011) Handbook of Face Recognition, , Springer London Dordrecht Heidelberg, New YorkChingovska, I., Anjos, A., Marcel, S., On the effectiveness of local binary patterns in face anti-spoofing IEEE International Conference of the Biometrics Special Interest Group, (2012). , Darmstadt, 6-7 SeptemberPan, G., Sun, L., Wu, Z., Lao, S., Eyeblink-based anti-spoofing in face recognition from a generic webcamera (2007) IEEE 11th International Conference on Computer Vision, pp. 1-8. , Rio de Janeiro, 14-21 OctoberTan, X., Li, Y., Liu, J., Jiang, L., Face liveness detection from a single image with sparse low rank bilinear discriminative model (2010) 11th European Conference on Computer Vision: Part VI.
