Why Photoshop doesn't provide secure metadata

If I understand what you're looking for -- a way to distribute your image so that somebody can't strip out the copyright, the only way to come close is to embed the copyright in the image with a watermark, either visible or invisible. Digimarc can do it with a mostly-invisible watermark. The less visible it is, the less robust it is to image manipulation.

It's not just that the capability is lacking in Photoshop to attach a non-removable copyright. It is not logically possible to put a copyright notice in metadata (not embedded in the image data) in a way that it can't be removed.
