Abstract
Disclosed are methods/systems to embed a watermark into a contone image. Specifically, the disclosed methods and systems spatially modulate a contone image substantially adjacent a watermark area according to a first polarization and spatially modulate the contone image substantially within the watermark area according to a second polarization. These spatially modulated images may then be subsequently processed, stored, communicated and/or rendered.
