SynthID-Text watermark partially survives LLM rewrites, study finds

By PulseAugur Editorial · [1 sources] ·

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.

    <p>In my <a href="https://dev.to/vadim_albarov/can-a-local-llm-wash-out-a-watermark-without-washing-out-the-meaning-i-tested-300-rewrites-15jb">last post</a> I asked whether a local LLM can rewrite an AI text enough to break its word patterns while keeping the meaning. The answer…
