1. A method utilizing steganographic embedding comprising:
- associating usage fights with media, wherein the usage rights are to be used by a rights management system to control how the media is handled by the system;
in response to said associating, automatically providing an identifier; and
embedding—
through utilizing a processor or electronic processing circuitry—
the identifier in the media in a steganographic manner, said act of embedding alters at least some data representing the media to carry the identifier.

17. A method comprising:
-
querying a rights management system to register media therein, designating desired usage rights for the media, wherein the usage rights are to be used by a rights management system to control how the media is handled by the system; in response to said designating, receiving without requiring user or operator input a plural-bit identifier; and hiding—
through utilizing a processor or electronic processing circuitry—
the plural-bit identifier in the media in a steganographic manner. - View Dependent Claims (18, 19, 20, 21)
