XSA-MAD: Cross-modal Semantic Alignment for Morphing Attack Detection

Jie Jin, Mahiro Tokumasu, Yu Makino +2

Morphing attacks pose a serious threat to face recognition systems. However, existing image-based morphing attack detection (MAD) methods often generalize poorly to unseen generati…

Face Re-morphing: Differential Morphing Attack Detection via Feature-Space Similarity Changes

Jie Jin, Masakatsu Nishigaki, Tetsushi Ohki

Face morphing attacks pose a serious threat to face recognition systems because a single morphed document image can be matched to multiple contributors. Differential morphing attac…

Enhancing Remote Adversarial Patch Attacks on Face Detectors with Tiling and Scaling

Masora Okano, Koichi Ito, Masakatsu Nishigaki +1

This paper discusses the attack feasibility of Remote Adversarial Patch (RAP) targeting face detectors. The RAP that targets face detectors is similar to the RAP that targets gener…
