The present invention relates generally to steganographic encoding and/or digital watermarking. In one embodiment, a method is provided including: obtaining an image or video; encoding a first steganographic component in the image or video, wherein the first steganographic component comprises a first set of properties that are designed to be affected in a first manner when transformed from a first color gamut to a second color gamut; and encoding a second steganographic component in the image or video, wherein the first steganographic component comprises a second set of properties that are designed to be affect in a second manner when transformed from the first color gamut to the second color gamut. Other implementations and embodiments are provided and claimed as well.

What is claimed is: 1. A method comprising: obtaining an image or video; encoding a first steganographic component in the image or video, wherein the first steganographic component comprises a first set of properties that are designed to be affected in a first manner when transformed from a first domain to a second domain; and encoding a second steganographic component in the image or video, wherein the first steganographic component comprises a second set of properties that are designed to be affected in a second manner when transformed from the first domain to the second domain. 2. The method of claim 1 wherein the first set of properties comprises a signal to noise ratio. 3. The method of claim 1 wherein the second set of properties comprises a signal to noise ratio. 4. The method of claim 1 wherein the second set of properties comprises a signal bias. 5. The method of claim 1 wherein the first set of properties or the second set of properties comprises a power level. 6. The method of claim 1 wherein the first set of properties or the second set of properties comprise at least one property associated with pixels. 7. The method of claim 6 wherein the one property comprises pixel alignment. 8. The method of claim 6 wherein the second set of properties comprises a random assignment of pixels. 9. The method of claim 1 wherein the first set of properties or the second set of properties comprise at least one property associated with grain. 10. The method of claim 1 wherein the first domain or the second domain comprises a transform frequency domain. 11. The method of claim 1 wherein the first domain comprises a first color gamut and the second domain comprises a second color gamut. 12. A method comprising: obtaining an image or video; hiding a first component in the image or video, wherein the first component is designed to change in a first manner when transformed from a first domain to a second domain; and hiding a second component in the image or video, wherein the second component is designed to change in a second manner when transformed from a first domain to a second domain. 13. The method of claim 12 wherein the first domain or the second domain comprises a transform frequency domain. 14. The method of claim 12 wherein the first domain comprises a first color gamut and the second domain comprises a second color gamut. 15. The method of claim 12 wherein said acts of hiding are accomplished with digital watermarking. 16. A method comprising: obtaining an image or video, the image or video including a first component and a second component hidden therein, wherein the first component is hidden to change in a first manner when transformed from a first domain to a second domain, and the second component is hidden to change in a second manner when transformed from the first domain to the second domain; analyzing properties associated with the first component and the second component; determining from at least said act of analyzing whether the image or video has undergone a transformation from the first domain to the second domain. 17. The method of claim 16 wherein the properties comprise a signal to noise ratio. 18. The method of claim 16 wherein the properties comprise a signal bias. 19. The method of claim 16 wherein the properties comprise a power level. 20. The method of claim 16 wherein the properties comprises a random assignment of pixels. 21. The method of claim 16 wherein the first domain or the second domain comprises a transform frequency domain. 22. The method of claim 16 wherein the first domain comprises a first color gamut and the second domain comprises a second color gamut.
