What Breaks Local Watermarks? A Robustness Benchmark for Local Invisible Image Watermarking
This work presents the first systematic robustness benchmark for local watermark robustness across 55 image transformations, and finds that signal distortions are often tolerated by the strongest methods, while geometric misalignment and generative local edits can completely impair payload recovery.
