>>3198653>What is a shame is there is no way to put invisible watermarks that would show up all over the photo when scanned.http://smallbusiness.chron.com/create-hidden-watermark-word-shows-document-copied-77951.htmlYou could also use glass nanospheres like in that anti-paparazzi clothing that whites out everything when someone takes a photo using a flash. The scanner light is super bright and should cause a similar problem. All you'd need to do is use it to create a watermark on the original photo.
