AI Technical Summary
Existing red and green list watermarking technologies suffer from problems such as reduced text quality due to hard red lists and low detection rates and poor robustness of soft red lists, making it difficult to strike a balance between ensuring text quality and watermark detection rate.
An adaptive method using dynamic red and green lists is adopted. Red and green lists of terms are generated through hash keys, and exemption rules are introduced to dynamically adjust the selection of candidate words during the generation process to ensure text fluency. At the same time, a high detection rate is achieved through strict exemption rules during the detection phase.
It effectively balances text quality and watermark strength, ensuring the readability of the generated text and the accuracy of detection, improving the watermark detection rate and reducing system overhead.
