Deep Bio-Hashing Network for Privacy-Preserving Cancelable Finger Vein Recognition.

This paper proposes Deep Bio-Hashing Network (DBHN) for privacy-preserving finger vein recognition, achieving end-to-end cancelable recognition and proposes a Deep Bio-Hashing layer to tackle the security problem caused by stolen tokenized random numbers.

Robust Bimanual Vision-Language-Action Models via Embarrassingly Simple Modality Masking

The Modality Masking Mechanism (M3), an embarrassingly simple, training-only strategy that requires no architectural changes or large-scale robot pretraining, is introduced to improve robustness of query-based VLA policies for bimanual manipulation.

DEFUSE: Generalizable Backdoor Defense for Self-Supervised Encoders with Generative Priors

Inspired by Bayesian posterior inference, this work reformulate backdoor detection as a representation-conditioned image likelihood estimation problem parameterized by a conditional diffusion generative model, and fine-tune a pretrained diffusion model, leveraging its generative prior to map data onto the natural image...

PANDA: Diffusion-Guided Purification and Adaptation for Robust Point Cloud Classification Against Adversarial Attack

Deep learning models for point cloud classification are highly vulnerable to adversarial attacks, while recent advances in diffusion-based purification have shown promising defensive performance. However, existing diffusion-based purification methods harbor two fundamental limitations. First, a distributional gap arise...

The Platonic Defense: Backdoor Defense for Self-Supervised Encoders in the Era of Large Scale Pre-training

A new attack-agnostic, model-agnostic, and modality-agnostic black-box test-time defense paradigm, inspired by the Platonic Representation Hypothesis, that can perform both representation detection and purification, and achieves substantial performance gains across multiple attacks.
