On Google's SynthID-Text LLM Watermarking System: Theoretical Analysis and Empirical Validation
Researchers have conducted the first theoretical analysis of Google's SynthID-Text watermarking system, revealing vulnerabilities in its detection methods and proposing attacks that can break the system. The study identifies weaknesses in the mean score detection approach and demonstrates that the Bayesian score offers better robustness, while establishing optimal parameters for watermark detection.
