Abstract
Abstract Images are steganographically marked with codes that can be used, e.g., by reference to a remote registry, to identify the image proprietors. Some embodiments pre-mark blank emulsion film or paper products with such codes, so that images formed thereon can be traced back to their proprietors. A variety of other embodiments and technologies are also disclosed.
