Degradation & Adversarial Attack
The Verge Insight: Even when users toggle off Google Gemini's visible corner logo, DeepMind's SynthID frequency embedding remains imperceptibly distributed across harmonic bands, surviving compression and cropping.

DeepMind SynthID Breakdown
How SynthID Works: DeepMind alters pseudo-random frequency components during diffusion token sampling. Because the key is spread harmonically across the whole image, cropping 30% of the pixels or applying social media compression preserves ~70-90% detection confidence.
