Stefan H\"ormann, Tianlin Kong, Torben Teepe, Fabian Herzog, Martin, Knoche, Gerhard Rigoll

TL;DR
This paper presents a simple yet effective face morphing method using a pretrained face recognition model integrated into a GAN, revealing significant vulnerabilities in current face recognition systems to morphed face attacks.
Contribution
The authors introduce a novel face morphing technique that works across diverse scenarios and demonstrate its effectiveness in fooling state-of-the-art face recognition systems.
Findings
Morphed faces achieve high similarity to two identities
Current FR systems only achieve 55-70% accuracy on morphed faces
The method works in unconstrained scenarios
Abstract
State-of-the-art face recognition (FR) approaches have shown remarkable results in predicting whether two faces belong to the same identity, yielding accuracies between 92% and 100% depending on the difficulty of the protocol. However, the accuracy drops substantially when exposed to morphed faces, specifically generated to look similar to two identities. To generate morphed faces, we integrate a simple pretrained FR model into a generative adversarial network (GAN) and modify several loss functions for face morphing. In contrast to previous works, our approach and analyses are not limited to pairs of frontal faces with the same ethnicity and gender. Our qualitative and quantitative results affirm that our approach achieves a seamless change between two faces even in unconstrained scenarios. Despite using features from a simpler FR model for face morphing, we demonstrate that even…
