I used to use watermarking on some of my photos. There's really no way 
to watermark a photo in a way that can't be essentially negated via 
graphic manipulations.

I think that if the software needed to verify the watermark is open 
source, anyone will know how to identify the elements of the file that 
comprise the watermark. Then they'll also know how to remove them.
