Discovering, detecting, and surgically removing Google's AI watermark through spectral analysis Overview This project reverse-engineers Google's SynthID watermarking system - the invisible watermark embedded into every image generated by Google Gemini. Using only signal processing and spectral analysis (no access to the proprietary encoder/decoder), we: Discovered the watermark's resolution-dependent carrier frequency structure Built a detector that identifies SynthID watermarks with 90% accurac...
