UnverifiedText 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.71% similarUnverifiedScenario-differentiated watermarking may become a trend, applying stronger watermarks to purely generative content while adopting lighter or selective strategies for critical tokens involving tool calls and code execution.68% 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).67% similarUnverifiedInvisible watermarking technology embeds statistical signals during the generation phase of large language models by fine-tuning the token sampling strategy (dividing the vocabulary into green and red tokens and biasing toward green tokens).67% similarUnverifiedMore robust watermarking research directions include watermarks based on semantics rather than surface tokens, or the adoption of more sophisticated hash-window strategies.66% similar
