ABSTRACT:
A digital watermark may be applied to digital image data to produce watermarked digital image data. A transformation may be applied to the watermarked digital image data to produce transformed watermarked digital image data. The transformation may approximate the inverse of a transformation that represents distortion caused by transmission through a print-scan channel.
