Effective AI Watermarking Requires Embedded Multi-Layer Solutions

The post points out that while many treat C2PA as an AI watermark standard, it is essentially file-attached metadata rather than embedded content. Metadata is easily stripped via screenshots, re-encoding, or social media uploads, causing the new file to lose traceability.
The author explains that truly effective solutions require embedding watermarks directly into the content, typically using multiple layers. For instance, frequency-domain watermarks resist standard compression and scaling, while neural watermarks better withstand stronger attacks like screenshot re-capture and re-encoding.
