LambdaMark: Semantic Audio Watermarking for Robustness and Radioactivity
Researchers introduce LambdaMark, a novel audio watermarking technique that embeds multi-bit information into semantic audio representations to prevent unauthorized voice cloning and speaker impersonation. Unlike existing methods that operate on low-level signals, LambdaMark achieves both robustness against distortions and 'radioactivity'—the property of being learned and preserved by downstream finetuned models—making it significantly more resistant to removal attacks.
