Hidden in Plain Sight: Are Modern Watermarks Truly Secure?
![The robustness of three watermarking schemes-Videoseal, TrustMark, and Broken-Arrows-was evaluated by measuring the attack success rate (ASR) as a function of peak signal-to-noise ratio (PSNR), revealing that schemes with smaller areas under their respective curves demonstrate greater resilience against attacks attempting to remove or disable the embedded watermark-a metric of security achieved through minimizing vulnerability to signal degradation [latex]PSNR[/latex].](https://arxiv.org/html/2605.27135v1/x7.png)
A new study casts doubt on the security of contemporary watermarking techniques, revealing they may be less resistant to attack than older methods.
