I get what you’re going for but this would absolutely wreck privacy. And depending on how those signatures are created, someone could create a virtual camera that would sign images and then we would be back to square one.
Privacy concern for sure, but given that you can already tie different photos back to the same phone from lens artifacts, I don’t think this is going to make things much worse than they already are.

Anyone who produces cameras can publish a list of valid keys associated with their camera. If you trust the manufacturer, then you also trust their keys. If there’s no trusted source for the keys, then you don’t trust the signature.

I don’t have a better idea though.
The point is to give photographers a “receipt” for their photos. If you don’t want the receipt it would be easy to scrub from photo metadata.
