Applications of Information Hiding and Digital Watermarking

Digital watermarking denotes the hiding of information in general documents, where the embedded information can be exploited to combat copyright infringements or to verify the integrity of a document. We emphasize that blind watermarking, where the original document is not known to the watermark receiver, can be interpreted as communication with side information at the encoder. Significant improvements over state-of-the-art watermarking schemes can be achieved when using this side information. The new watermarking technology broadens the range of possible applications for digital watermarking and information hiding, which is demonstrated for three example applications.
