The green list/red list scheme works by using the previous token as a hash seed at each token generation step to divide the vocabulary into a green list and a red list, applying a positive logit bias to green-list tokens, and detecting whether the proportion of green-list tokens is significantly above 50% during verification.

UnverifiedKGW算法在每个token生成时利用前一个或前几个token作为伪随机种子将词表划分为绿名单和红名单，采样时对绿名单token施加正向偏置，检测时统计绿名单token比例是否显著高于随机基线78% similarUnverifiedMainstream LLM watermarking schemes typically intervene at the token sampling stage, dividing the vocabulary into a green list and a red list based on the hash value of preceding context, and biasing sampling toward green-list tokens.73% similarVerifiedWhen generating each token, the watermarking algorithm randomly partitions the vocabulary into a green list and a red list based on a hash of the preceding context, and slightly increases the probability of green list tokens being selected.72% similarUnverifiedKirchenbauer方案根据前文哈希值将词汇表随机划分为绿名单和红名单，通常γ=0.5，并在绿名单token的logits上加固定偏置δ（通常取1-2之间）72% similarUnverifiedKirchenbauer方案通常将前一个token的ID与保密密钥拼接后输入哈希函数（如SHA-256）生成伪随机数种子，前γ比例（通常γ=0.5）的token归入绿名单61% similar
