The paper introduces REMARK, a watermark‑based fingerprint framework designed to verify ownership of Graph Neural Networks (GNNs). REMARK generates in‑distribution watermark graphs that maximize output differences between GNN models, thereby reducing performance loss from out‑of‑distribution watermarks. It then extracts robust fingerprints from these output differences, eliminating the need for surrogate models trained on watermark data or reliance on specific output levels, and achieves state‑of‑the‑art verification accuracy across real‑world datasets and GNN architectures.

The paper introduces Imperfect Restoration Poisoning (IRP), a new data poisoning technique that maintains high image quality while effectively disrupting both supervised and self‑supervised learning models. It builds on a theoretical critique of the existing Convolution-based Unlearnable Dataset (CUDA) method, revealing CUDA’s sub‑optimal gradients and class‑bias strategy. Extensive experiments demonstrate IRP’s superiority over eight baseline attacks and its resilience against five defense methods.

arXiv:2606. 31653v1 Announce Type: cross Abstract: Certified training aims to produce models whose predictions can be formally verified against adversarial perturbations, typically by optimising upper bounds on the worst-case loss over an allowed perturbation set.

arXiv:2606. 08467v1 Announce Type: cross Abstract: While confidence calibration is essential for trustworthy decision-making in safety-critical applications, the robustness of calibrated GNNs to adversarial structural perturbations remains largely unexplored.
