Having an invisible watermark still won't stop people from grabbing your images. Sure, you can "prove" it's yours, but so what? You could have done that anyway, more than likely, by showing wireframe views, or layered .psd files, or the raw render, or any number of other ways of showing it. Generally speaking, the sort of person who will steal images won't care if there's an "invisible" mark/encryption in it, any more than hardcore burglers care if there's a sign saying "Warning, this property protected by XYZ alarm system". More on Digimarc at the link. BUT... this is getting off topic. What apparently happened here is that someone deliberately took images and then pretended to be that person, which is not only copyright violation, it's really, seriously, CREEPY. The only thing that will help in a situation like that is going to be professional psychiatric help for the person who perpetrates such a thing. bonni
