Best Paper for ATHENE researchers at WIFS 2021
ATHENE researchers from the Biometrics and Internet-Security Research Group at Darmstadt University of Applied Sciences received the Best Paper Award at the 13th IEEE International Workshop on Information Forensics and Security (WIFS 2021) for their paper "Differential Anomaly Detection for Facial Images". WIFS is the primary annual event organized by the IEEE Information Forensics and Security (IFS) Technical Committee of the IEEE Signal Processing Society. It aims to bring together researchers from relevant disciplines to discuss challenges, exchange ideas and share the state-of-the-art results and technical expertise in the ares of information security and forensics.
Authors of the paper are Mathias Ibsen, Lazaro Janier Gonzalez-Soler, Christian Rathgeb, Pawel Drozdowski and Christoph Busch, all Darmstadt University of Applied Sciences, and Marta Gómez-Barrero from Ansbach University of Applied Sciences.
Short introduction to the paper:
Due to their convenience and high accuracy, face recognition systems are widely employed in governmental and personal security applications to automatically recognise individuals. However, despite recent advances, face recognition systems have shown to be particularly vulnerable to identity attacks (i.e., digital manipulations and attack presentations). Identity attacks pose a big security threat as they can be used to gain unauthorised access and spread misinformation. In this context, most algorithms for detecting identity attacks generalise poorly to attack types that are unknown at training time. To tackle this problem, we introduce a differential anomaly detection framework in which deep face embeddings are first extracted from pairs of images (i.e., reference and probe) and then combined for identity attack detection. The experimental evaluation conducted over several databases shows a high generalisation capability of the proposed method for detecting unknown attacks in both the digital and physical domains.
