ABSTRACT:
A digital watermark embedding apparatus comprises a digital watermark generating unit which transforms embedding target contents by using a filter having a coefficient with a periodic number sequence to generate a digital watermark, and an embedding unit which superposes the digital watermark on the embedding target contents to generate watermark embedded contents.
