SynthID-Bypass is an AI safety research project demonstrating a vulnerability in Google's SynthID—the invisible digital watermark embedded in images generated by Gemini (Nano Banana Pro) to identify them as AI-generated. --- The Problem: Google's SynthID watermark can be removed. The Method: Two ComfyUI workflows that "re-render" watermarked images through a diffusion model pipeline using:
Low-denoise regeneration
ControlNet structural guidance
Multi-pass processing
The Result: Processed images pass Google's own SynthID detection as "not AI-generated" while preserving visual content. --- Why Release This? This is responsible disclosure research. By exposing the weakness, we aim to:
Highlight limitations in current AI content authentication
Encourage development of more robust watermarking techniques
Invite the community to create bypass-resistant watermarks
