This technology could be used to copyrights as well.

>The watermark doesn’t change the image or video quality. It’s added the moment content is created, and designed to stand up to modifications like cropping, adding filters, changing frame rates, or lossy compression.

But does it survive if you use another generative image model to replicate the image?

It doesn't. I don't have a link for you right now but there was a post on reddit recently showing that SynthID is removed from images by passing the image through a diffusion model for a single step at low denoise. The output image is identical to the input image (to the human eye).

That's been a thing for a while: https://en.wikipedia.org/wiki/Digital_watermarking

Extremely doubtful, due to the way that embedding and diffusion works. I would be utterly floored if they had achieved that.
