Definition
Google DeepMind's watermarking and detection system for AI-generated content. For images, it modifies pixel values during generation using a trained encoder network. For audio, it embeds a signal in the spectrogram. A paired detector network reads watermark presence from any derivative copy and reports a detection probability.
