SynMorph: Generating Synthetic Face Morphing Dataset with Mated Samples
This addresses the problem of dataset scarcity for researchers developing face morphing attack detection algorithms, though it is incremental as it builds on existing synthetic data methods.
The authors tackled the lack of large-scale public datasets for face morphing attack detection by generating a synthetic dataset with 2450 identities and over 100k morphs, which showed improvement over state-of-the-art benchmarks in quality and vulnerability analysis.
Face morphing attack detection (MAD) algorithms have become essential to overcome the vulnerability of face recognition systems. To solve the lack of large-scale and public-available datasets due to privacy concerns and restrictions, in this work we propose a new method to generate a synthetic face morphing dataset with 2450 identities and more than 100k morphs. The proposed synthetic face morphing dataset is unique for its high-quality samples, different types of morphing algorithms, and the generalization for both single and differential morphing attack detection algorithms. For experiments, we apply face image quality assessment and vulnerability analysis to evaluate the proposed synthetic face morphing dataset from the perspective of biometric sample quality and morphing attack potential on face recognition systems. The results are benchmarked with an existing SOTA synthetic dataset and a representative non-synthetic and indicate improvement compared with the SOTA. Additionally, we design different protocols and study the applicability of using the proposed synthetic dataset on training morphing attack detection algorithms.
