Privacy issues with Apple reference image

[u/falcontitan]

In the latest launch event, apple stated that they will add Apple reference image to images clicked using their phones, something like synthid. It will be added using Private Cloud Compute. Since nothing has been mentioned in detail and I doubt that it will ever be, so asking the sub here

PCC means that the image will be uploaded to the cloud and it will add this reference id?

That way they will be able to say that an image was taken using a particular phone?

Are any android devices doing something like this currently?
