Invisible, robust watermarks had a lot of attention in research from the late 90s to the early 10s, and apparently some resurgence with the availability of cheap GPU power.

Naturally there's a python library [1] with some algorithms that are resistant to lossy compression, cropping, brightness changes, etc. Scaling seems to be a weakness though.
