Abstract
Abstract The present invention relates to steganographic encoding for multimedia content. In one combination, a method is provided including: encoding first information in a first component of a multimedia signal, the first component comprising audio, the first information being encoded though subtle changes to data representing the first component; encoding second information in a second component of the multimedia signal, the second component comprising video, the first information being encoded though subtle changes to data representing the first component, the first information and the second information are associated. Of course, other combinations are provided as well.
