Abstract
Abstract The invention efficiently controls the method for embedding digital watermark information into digital information or detecting such digital watermark information. Also in case the digital information has components of different kinds, the invention enables individual management of the digital watermark information and information indicating the embedding method therefor. In a configuration for attaining these objects, there are provided input means for inputting the digital information composed of signal components of plural kinds, and control means for controlling the method for embedding the digital watermark information in the signal component of a first kind contained in the signal components of plural kinds, based on the signal component of a second kind contained in the signal components of plural kinds.
