Imagine a world where a copy of your face could trick the most advanced security systems. This isn’t science fiction; it’s a real challenge today. LivDet-Face is a competition that aims to advance the detection of attacks at the biometric sensor, known as Presentation Attack Detection (PAD). This international contest is a key benchmark in biometric security, offering an unbiased look at the latest innovations in face PAD and demonstrating progress over time in detecting and preventing sophisticated attacks. Through the International Joint Conference on Biometrics (IJCB) platform, LivDet-Face 2024 provides a standardized evaluation process, access to advanced Presentation Attack Instruments (PAI), and a comprehensive dataset of bona fide face images. The competition had two main categories: algorithms and systems. A total of sixteen algorithms and one system were submitted for this year’s competition. Anonymous submissions topped both image and video subcategories with an ACER of 4.93% and 4.13%, respectively. In the systems category, Team Dermalog, despite being the sole submission, achieved an impressive ACER of 3.12%.

Presentation Attack Detection (PAD) is essential for ensuring the security of face recognition (FR) systems, particularly in the context of mobile authentication in various sectors, such as online banking and government services. However, current PAD methods are often sensitive to the data domain, partly due to the limitations of training PAD datasets. In this paper, we introduce the SO-TERIA dataset, which provides captures of bona-fide and diverse Presentation Attacks (PAs) recorded using smart-phones. The dataset was collected responsibly from 70 consenting individuals, as opposed to web scraping. It includes face videos, motion data, and depth information (when available) as well as a novel projector-based replay attack. To demonstrate the utility of the SOTERIA dataset, we evaluate the vulnerability of a SOTA FR model (IRes-Net100) to the PAs in the dataset. We also analyze the PAD capabilities of a SOTA PAD model (DeepPixBis) through cross-dataset experiments as well as on real attacks observed in an industrial application. Our findings show the effectiveness and versatility of the SOTERIA dataset in advancing PAD research, in particular toward generalization.

The proliferation of automated face recognition (FR) necessitates increasingly accurate person identification. The COVID-19 pandemic has exposed the limitations of FR systems when presented with faces occluded by hygienic masks. However, the security risks of personalised hygienic mask attacks, whereby an attacker wears the mask on which the bottom part of an enrolled user’s face is printed, have not yet been studied. To address this research gap, we introduce a novel face dataset consisting of smartphone-recorded videos of real (bona-fide) faces and personalised hygienic mask attacks. We also analyse the vulnerability of two state-of-the-art FR systems to this type of attack, using our dataset. Our results indicate that personalised hygienic mask attacks have the potential to compromise system security, particularly for FR systems that are tuned towards optimising user convenience. These findings underscore the importance of developing suitable Presentation Attack Detection (PAD) algorithms. Our dataset will help researchers and practitioners work towards this goal, thereby enhancing the security and reliability of FR systems.
