Google is apparently fingerprinting their nano banana created images for copyright purposes..... so if you use them for commerce then they can sue you or demand payment. Their fingerprinting is purposefully made in a way to be hidden.

I considered that the way this likely works is they use a random seed that is encoded into the image "somewhere". This seed dictates things like:

• count every x pixels
• algorithm determines the difference between pixels.

So what you end up with is a red pixel that is a set number of points off from the red it's supposed to be and an exact distance between two other pixels that are an exact distance off from the color they are supposed to be. This can very easily be subtly hidden within an image and undetectable by a human or an algorithm.

If we could write algorithms to solve hidden things like this then we would be able to also crack every encryption known to man. It isn't easily possible to recognize such patterns..... so in this regard, the people adding fingerprints to things have a leg up on the white hats that wish to identify societal control mechanisms.
