UnverifiedKirchenbauer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74% similarUnverifiedThe 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.72% similarUnverifiedWhen 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.67% similar
