Google's SynthID is embedded into the content itself. Google open sourced their SynthID for text. Repo: https://github.com/google-deepmind/synthid-text https://github.com/google-deepmind/synthid-text Paper: https://www.nature.com/articles/s41586-024-08025-4 https://www.nature.com/articles/s41586-024-08025-4 With images and video, it's less clear exactly what they're doing, but it's watermarking on the pixel leve. From one of their blog posts: Videos are composed of individual frames or still images. So we developed a watermarking technique inspired by our SynthID for image tool. This technique embeds a watermark directly into the pixels of every video frame, making it imperceptible to the human eye, but detectable for identification. https://deepmind.google/discover/blog/watermarking-ai-generated-text-and-video-with-synthid/ https://deepmind.google/discover/blog/watermarking-ai-genera... Elevenlab's audio watermarking is trivial to shake off with compression, but google claims that synthid is resilient to such manipulation.
