I, for one, do believe watermarking solutions exist. One thing you cannot escape with LLMs is content meaning. As a simple example, the secret watermark could be hidden in the embeddings of the sequence of words. To make the watermark more robust against rephrasings, it could be hidden in the meaning of sentences or paragraphs. At the minimum, I think this could be possible.
