Removing the Watermark Is Not Enough: Forensic Stealth in Generative-AI Watermark Removal

Beyond fooling watermark verifiers, researchers show attackers must also achieve forensic stealth—raising the bar for evaluating generative-AI watermark robustness.

arXiv:2605.09203v2 Announce Type: replace Abstract: The literature on watermark removal has largely asked whether an attacker can make the watermark verifier fail while preserving the appearance of the image. This is a useful test, but it does not capture the purpose of removal in applications where watermarks support provenance. In such settings, the attacker wants the image to pass as ordinary content. If the removal process leaves a recognizable statistical trace, the watermark may have disa

Editorial Analysis

Why it matters

Enterprises relying on AI watermarking for content provenance under the EU AI Act should note that current robustness evaluations may underestimate real adversarial capability.
