On the Study of Biometric Spoofing Detection using Deep Learning
For biometric security researchers, this is an incremental evaluation of existing models on a standard dataset, highlighting known generalization issues.
This study evaluates deep learning models (MobileNetV2, DenseNet-121, Inception-v3, STD) for facial spoofing detection, finding MobileNetV2 achieves 92% accuracy on CelebA-Spoof but all models struggle with cross-dataset generalization.
Biometric systems are increasingly deployed in security applications; however, they remain vulnerable to spoofing attacks, in which attackers exploit counterfeit biometric data to gain unauthorized access. This research evaluates the effectiveness of state-of-the-art machine learning models, MobileNetV2, DenseNet-121, Inception-v3, and Spoof Trace Disentanglement (STD) in detecting spoofing attacks within facial recognition systems. Using the CelebA-Spoof dataset, the study evaluates model effectiveness using metrics such as accuracy, precision, recall, and F1 Score. Cross-dataset validation is carried out on the MSU-MFSD dataset to assess generalizability. The results show MobileNetV2 as the most efficient model, achieving 92% accuracy while balancing computational effectiveness, making it appropriate for real-life applications. Inception-v3 shows moderate robustness, while DenseNet-121 and STD struggle with generalization. The findings highlight the need for advances in domain adaptation and hybrid architectures to enhance biometric security systems.
