Original Abstract:

The robustness and generalization ability of Presentation Attack Detection(PAD) methods is critical to ensure the security of Face Recognition Systems(FRSs). However, in the real scenario, Presentation Attacks (PAs) are variousand hard to be collected. Existing PAD methods are highly dependent on thelimited training set and cannot generalize well to unknown PAs. Unlike PADtask, other face-related tasks trained by huge amount of real faces (e.g. facerecognition and attribute editing) can be effectively adopted into differentapplication scenarios. Inspired by this, we propose to apply taskonomy (tasktaxonomy) from other face-related tasks to solve face PAD, so as to improve thegeneralization ability in detecting PAs. The proposed method, first introducestask specific features from other face-related tasks, then, we design aCross-Modal Adapter using a Graph Attention Network (GAT) to re-map suchfeatures to adapt to PAD task. Finally, face PAD is achieved by using thehierarchical features from a CNN-based PA detector and the re-mapped features.The experimental results show that the proposed method can achieve significantimprovements in the complicated and hybrid datasets, when compared with thestate-of-the-art methods. In particular, when trained using OULU-NPU,CASIA-FASD, and Idiap Replay-Attack, we obtain HTER (Half Total Error Rate) of5.48% in MSU-MFSD, outperforming the baseline by 7.39%. Code will be madepublicly available.

Context On This Paper:

– The article proposes a method for improving the generalization ability of Presentation Attack Detection (PAD) methods in detecting various Presentation Attacks (PAs) by applying taskonomy from other face-related tasks.- The proposed method introduces task-specific features from other face-related tasks and uses a Cross-Modal Adapter with a Graph Attention Network (GAT) to re-map such features to adapt to the PAD task.- The experimental results show that the proposed method outperforms the state-of-the-art methods and achieves a Half Total Error Rate (HTER) of 5.48% in MSU-MFSD when trained using OULU-NPU, CASIA-FASD, and Idiap Replay-Attack datasets.

Flycer’s Commentary:

Detecting Presentation Attacks (PAs) is crucial for the security of Face Recognition Systems (FRSs). However, existing PAD methods are limited by their training sets and struggle to generalize to unknown PAs. To address this issue, researchers propose using taskonomy from other face-related tasks to improve the generalization ability of PAD. By introducing task-specific features and using a Cross-Modal Adapter with a Graph Attention Network (GAT), the proposed method achieves significant improvements in detecting PAs compared to state-of-the-art methods. This is particularly evident in complicated and hybrid datasets, where the proposed method outperforms the baseline by 7.39%. As a small business owner, it is important to consider the security of your FRSs and the potential benefits of using AI-based PAD methods to improve their robustness and generalization ability.
