One Watermark Survived; the Other Broke
A robust signal tracked provenance while a fragile companion signaled reader-visible tampering.
Summary
A robust signal tracked provenance while a fragile companion signaled reader-visible tampering.
Independent keys and seeding windows produced three detector outcomes: intact, tampered or unwatermarked. Tests on two models and two prompt datasets reported the strongest tamper detection among compared methods while preserving competitive attribution robustness.
Why it matters
