Robust LLM Watermarking with Minimal Semantic Distortion for IP Protection
SAFESEAL is a novel key-conditioned watermarking framework for LLMs that balances strong detectability with minimal loss of text utility. It works by replacing linguistic terms with context-aware synonyms, carefully avoiding named entities to preserve meaning. This method ensures that the embedded watermark is robust against removal attempts and allows for verifiable detection tied to specific users or providers.
