I wouldn't fool yourself: there are hundreds of people out there who can work out how to take an underwater image (bearing in mind that making an educated guess about how an image is made was Howard Hall's theme in "Successful Underwater Photography"). I can see an advantage in stripping out the EXIF files as part of establishing copyright, though.
