A Unified Evaluation Framework of Physical Adversarial Robustness in the Edge VLM Era

The paper introduces a unified evaluation framework for assessing the physical adversarial robustness of Vision‑Language Models (VLMs) deployed at the edge. It defines a conditional attack success rate (cASR) metric that counts only images where the model still localizes objects under a gray occluder, and categorizes failures into omission, substitution, and displacement. Benchmarking shows that compact grounding VLMs can be as vulnerable as traditional object detectors, with omission being the only failure visible to downstream systems, while displacement and substitution pose potentially more dangerous risks, especially under distribution shift.

LipSSD: Lipschitz-Constrained Single-Shot Detection for Adversarially Robust Object Detection

arXiv:2607. 06592v1 Announce Type: cross Abstract: Object detectors have many applications in safety-critical systems, but they are known to be sensitive to worst-case perturbations such as adversarial attacks, which limits their applicability in real-world scenarios.

Can Pixels Alone Reveal Image Origin? Minimax Limits and Learnable Interfaces for Passive Provenance

The paper investigates whether pixels alone can determine an image’s origin—human, AI class, or specific generator—under adversarial edits. It establishes a minimax limit: the best possible robust acceptance gap equals the minimum total‑variation distance between the target distribution and attacked source distributions, independent of verifier design. The study also shows that practical public verifiers can fail before reaching this theoretical ceiling, highlighting the need to evaluate both statistical limits and deployed verifier behavior separately.

LipSSD: Lipschitz-Constrained Single-Shot Detection for Adversarially Robust Object Detection

Object detectors have many applications in safety-critical systems, but they are known to be sensitive to worst-case perturbations such as adversarial attacks, which limits their applicability in real-world scenarios. Compared with classification, adversarial robustness for object detection has received less attention, and existing methods are often tied to adversarial training, whose performance may not transfer across attacks, perturbation budgets, or architectures.
