A system and a method for secure remote informed watermark detection making use of a side-information. The system in overview comprises a remote detector and a server computing system wherein a database with side-information assigned to specific descriptors of data signals is stored at the server computing system and wherein a remote detector intending to identify the watermark of a data signal will derive the descriptor of the data signal and subsequently contact the trusted server computing system in order to obtain the necessary side-information for the informed watermark detection.

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.

In an information embedding apparatus (110), an image selecting unit (130) selects original image data from an original image data group (120a), a decoder (140) detects a code from the selected original image data, and a candidate code determining unit (150) calculates a candidate code. A candidate code embedding unit (160) embeds the candidate code in the selected original image data.
