UnverifiedSynthID文本水印的核心机制是Token生成偏置法，即在大模型采样阶段对特定Token概率进行微调83% similarUnverifiedText watermarking is a proactive scheme that makes slight, rule-based adjustments to the probability distribution of a language model during the generation of each token, causing the output text to carry a signature that can be recovered algorithmically.77% similarUnverifiedWatermarking technology requires active cooperation from the model provider, and the watermark signal can be effectively removed through paraphrase attacks (rewriting the text with another model).74% similarUnverifiedSynthID-Text在理论上可证明在特定条件下不改变模型原始输出分布（distortion-free水印）70% similar
