METHODS AND SYSTEMS FOR STEGANOGRAPHIC PROCESSING

Media content (e.g., audio or visual) can be steganographically encoded for a variety of purposes. One such purpose relates to tracing rendered media content back to a particular time and place. For example, one claim recites a method including: receiving data representing media content, the media content is to be rendered to an audience assembled at a location; and then encoding tracing information in the data utilizing at least a programmed electronic processor, said encoding alters at least some portions of the data to hide the tracing information in the data, the tracing information is associated with a time and location of rendering the media content to the audience assembled at the location, the tracing information will permit an illicitly captured version of the rendered media content to be traced back to the time and location of the rendering. Of course, other combinations and claims are presented as well.
