Researchers have introduced AliMark, a novel framework designed to enhance the robustness of sentence-level watermarking against paraphrasing. Unlike previous methods that anchor watermarks in sentence semantics and are vulnerable to structural changes, AliMark treats watermarking as an encoding and alignment problem. It employs a two-stage detection strategy involving multiple restructured text variants and adaptive alignment to minimize costs, thereby improving resilience against sentence splitting and merging.
