Papers with watermarking methods
Robust and Minimally Invasive Watermarking for EaaS (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing watermarking methods use a target embedding to create watermarks, but this method results in each embeddable having the same component, making it difficult to remove the watermark. |
| Approach: | They propose to use embedding watermarks to protect EaaS from model extraction attacks . eaas is vulnerable to model extraction, highlighting the need for copyright protection . |
| Outcome: | The proposed method can watermark embeddings against model extraction attacks without sacrificing the quality of the embeddables. |
Watermarking Large Language Models: An Unbiased and Low-risk Method (2025.acl-long)
Copied to clipboard
| Challenge: | Recent advances in large language models (LLMs) have highlighted the risk of misusing them, raising the need for accurate detection of LLM-generated content. |
| Approach: | They propose a method to inject imperceptible identifiers into large language models (LLMs) this method is unbiased and preserves the original token distribution in expectation . |
| Outcome: | The proposed method preserves the original token distribution in expectation and has lower risk of producing unsatisfactory outputs in low-entropy scenarios compared to existing unbiased watermarks. |
PostMark: A Robust Blackbox Watermark for Large Language Models (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to detect LLM-generated text require access to the underlying LLM’s logits, which LLM providers are loath to share due to fears of model distillation. |
| Approach: | They develop a post-hoc watermarking procedure that inserts an input-dependent set of words into the text after the decoding process has completed. |
| Outcome: | The proposed method is more robust to paraphrasing attacks than existing methods. |
