This was the first I had heard of such a thing, so I looked it up <https://en.wikipedia.org/wiki/Photo_response_non-uniformity>. That’s just an artifact of the way image sensors are made, so it’s not deliberately designed to be a secret identification feature or anything; the article even says that it is possible to characterize the noise pattern for a given sensor, and subtract it out to produce higher-quality images, e.g. for metrology purposes.
