New method bounds prevalence of edited watermarked text

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method to estimate the prevalence of watermarked text within a corpus, even when documents have undergone unknown edits. This approach, termed a "power envelope," provides finite-sample bounds and confidence sequences for identifying the share of watermarked content. Simulations using text from OPT-1.3B and Qwen3-1.7B models, along with human documents, showed that the derived bounds generally cover the actual prevalence, though results can be sensitive to null error and the size of the reference sample.

    Prevalence Bounds for Edited Watermarked Text: Power Envelopes and Calibration Sensitivity

    Watermark detectors decide whether one document came from a watermarked language model. Auditors often need a different number: the share of a corpus that did. We study this share for Gumbel-max and green-list (KGW) watermarks when every document may have been edited by an unknow…
