The application discloses various methods and systems to provide substitute information or objects for, e.g., substitution when making copies of media objects (e.g., audio, video or images). One method includes: receiving i) an identifier obtained from a steganographic encoding encoded in a media object, and ii) state information associated with the steganographic encoding or associated with the media object; obtaining-from a storage location-a substitute media object corresponding to the identifier; adjusting the substitute media object in accordance with the state information; providing the adjusted, substituted media object. Another method includes: receiving an identifier obtained from a steganographically encoded media object; accessing memory associated with at least a portion of the identifier to obtain an address of a remote data repository, the remote data repository including at least a plurality of substitute media objects corresponding respectively to a plurality of identifiers; forwarding: i) at least a portion of the identifier obtained from the steganographic encoding, and ii) an instruction to the remote data repository at the address, wherein the instruction includes a request to provide a substitute media object corresponding to at least a portion of the identifier obtained from the steganographic encoding. Of course, other methods and combinations are provided as well.
