I claim: 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. 2. The method of claim 1 wherein said associating usage rights with media comprises granting a user usage rights. 3. The method of claim 2 wherein granting a user usage rights follows a purchase of the media. 4. The method of claim 1 wherein said providing a steganographic identifier comprises receiving an identifier. 5. The method of claim 1 further comprising associating the identifier with the media in a remote data repository. 6. The method of claim 1 further comprising controlling the media with reference to at least the embedded identifier. 7. The method of claim 1 wherein in addition to embedding the identifier, additional information is steganographically embedded in the media. 8. The method of claim 7 wherein the other information comprises at least a time or manner of accessing the media. 9. The method of claim 1 wherein said embedding the identifier in the media in a steganographic manner involves digital watermarking. 10. A computer readable medium comprising instructions or circuitry to perform the method of claim 1. 11. The method of claim 1 wherein the media comprises video or audio. 12. A method comprising: associating usage rights 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 hiding the identifier in the media in a steganographic manner, said act of hiding utilizes a processor or electronic processing circuitry, and said act of hiding alters at least some data representing the media to carry the identifier. 13. The method of claim 12 wherein said act of hiding utilizes digital watermarking. 14. The method of claim 13 wherein the digital watermarking alters values associated with the media to hide the identifier therein. 15. A computer readable medium comprising instructions or circuitry to perform the method of claim 12. 16. The method of claim 12 wherein the media comprises video or audio. 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. 18. The method of claim 17 wherein said act of hiding utilizes digital watermarking. 19. The method of claim 18 wherein the digital watermarking alters values associated with the media to hide the identifier therein. 20. A computer readable medium comprising instructions or circuitry to perform the method of claim 17. 21. The method of claim 17 wherein the media comprises video or audio.
