The present invention relates to digital watermarking. In a preferred
embodiment, media is embedded with one or more digital watermark
components. The media includes a blue color plane, a red color plane and
a green color plane. The digital watermark component is embedded in the
blue color plane, and scaled versions of the digital watermark component
are embedded in the red and green color planes. The scaling of component
in the red and green color planes helps insure that luminance
attributable to the blue color digital watermark component is reduced or
offset. A related watermark detection scheme is disclosed.
