According to the description in the article, "an outside observer cannot determine whether any pair of reference images were taken by the same device." and they "avoid even implicit public association between different photos taken by the same sensor"

Whatever that means in detail...

Nothing stops you not verifying, or simply stripping the verification off.

What you are prevented from doing is adding a verification to a photo outside of the iOS image pipeline, or modifying the photo with the verification still in tact.

I dont think this is relavent to that use case. It seems like this proposal would be an optional off by default feature. They also seem to be going to lengths to make it privacy first so the verified photos cannot be linked to a specific photographer.

Or have I understood the feature's capability completely wrong?
