SynthID-Text watermark partially survives LLM rewrites, study finds

A recent experiment explored the effectiveness of Google DeepMind's SynthID-Text watermarking against local large language models (LLMs). The study found that while LLMs could significantly alter AI-generated text to evade detection, a standard watermark detector still identified a portion of the rewritten texts. Specifically, detectors flagged between 3% and 41% of rewritten texts, with a more sensitive test identifying up to 89% of watermarked content in certain scenarios. The effectiveness of the watermark depended on the rewriting model's ability to preserve meaning, and a second rewrite pass did not improve detection rates. AI

IMPACT Investigates the resilience of AI text watermarking against LLM paraphrasing, impacting content authenticity and detection methods.

    I Watermarked 100 Texts With SynthID and Asked Local LLMs to Wash It Out. The Detector Still Saw Some of It.
