The application discloses various methods and systems to provide substitute or replacement components for media objects (e.g., audio, video or images). The substitute or replacement components can be substituted for or to replace corresponding components when making copies of media objects. One claim includes: an apparatus comprising: a processor; and memory. The memory includes instructions for execution by said processor. The instructions include instructions to: upon receipt of a copy request, determine whether an object to be copied comprises a steganographic signal hidden within at least one component of the object; if the object comprises a steganographic signal hidden therein, obtain a substitute or replacement component corresponding to the steganographic signal; and execute the copy request of the object to yield a copy object including providing in the copy object the substitute or replacement component for the at least one component of the object. Of course, other apparatus, methods and combinations are provided as well.
