Face anti-spoofing (FAS) plays a vital role in preventing face recognition systems from presentation attacks. Existing face anti-spoofing datasets lack diversity due to the insufficient identity and insignificant variance, which limits the generalization ability of FAS model. In this paper, we propose Dual Spoof Disentanglement Generation (DSDG) framework to tackle this challenge by "anti-spoofing via generation". Depending on the interpretable factorized latent disentanglement in Variational Autoencoder (VAE), DSDG learns a joint distribution of the identity representation and the spoofing pattern representation in the latent space. Then, large-scale paired live and spoofing images can be generated from random noise to boost the diversity of the training set. However, some generated face images are partially distorted due to the inherent defect of VAE. Such noisy samples are hard to predict precise depth values, thus may obstruct the widely-used depth supervised optimization. To tackle this issue, we further introduce a lightweight Depth Uncertainty Module (DUM), which alleviates the adverse effects of noisy samples by depth uncertainty learning. DUM is developed without extra-dependency, thus can be flexibly integrated with any depth supervised network for face anti-spoofing. We evaluate the effectiveness of the proposed method on five popular benchmarks and achieve state-of-the-art results under both intra- and inter- test settings. The codes are available at https://github.com/JDAI-CV/FaceX-Zoo/tree/main/addition_module/DSDG.

人脸反欺骗旨在防止人脸识别系统将假面孔识别为真正的用户。虽然先进的面部反欺骗方法被开发出来,但新类型的欺骗攻击也正在产生,并成为对所有现有系统的威胁。我们将未知欺骗攻击的检测定义为零镜头人脸反欺骗(Zero-Shot Face Anti-Spoofing,简称ZEFA)。以前的研究工作只研究了1-2种欺骗攻击,如打印/重放攻击,这限制了对该问题的深入了解。在这项工作中,我们扩展的欺骗攻击,包括打印攻击,重放攻击,3D面具攻击等13种类型的广泛的欺骗问题,提出了一种新的深度树网络(DTN)来解决的欺骗问题。学习树以无监督的方式将欺骗样本划分为语义子组。当数据样本到达时,无论是已知攻击还是未知攻击,DTN都将其路由到最相似的欺骗集群,并做出二分判决。此外,为了使研究的反欺骗FA,我们介绍了第一个面对反欺骗数据库,其中包含不同类型的欺骗攻击。实验结果表明,该方法在多个测试协议上达到了最佳的测试效果。

人脸反欺骗对于防止人脸识别系统的安全漏洞至关重要。由于深度神经网络的优异性能和大数据集的可用性,生物识别社区最近取得了令人印象深刻的进展。虽然种族偏见已被证实严重影响人脸识别系统的性能,它仍然是一个开放的人脸反欺骗的研究问题。最近,一个多种族人脸反欺骗数据集CASIA-SURF CeFA已经发布,其目标是测量种族偏见。它是迄今为止最大的跨种族人脸反欺骗数据集,涵盖$3$种族,$3$模式,$1,607$主题,2D加3D攻击类型,以及最近发布的人脸反欺骗数据集中第一个包含明确种族标签的数据集。我们组织了Chalearn Face Anti-spoofing Attack Detection Challenge,其中包括单模态(例如,RGB)和多模态(例如,RGB,深度,红外(IR))围绕这一新资源进行跟踪,以促进旨在减轻种族偏见的研究。两个赛道在开发阶段都吸引了$340$团队,最终分别有11支和8支团队在单模态和多模态人脸反欺骗识别挑战赛中提交了代码。所有的结果都经过组织团队的验证和重新运行,结果用于最终排名。本文概述了挑战,包括其设计,评估协议和结果总结。我们分析排名靠前的解决方案,并从竞争中得出结论。此外,我们还概述了今后的工作方向。
