Digital watermarking of multimedia (e.g., audio, images, video, etc.) can be viewed as a communications problem in which the watermark must be transmitted and received through a \watermark channel." The watermark channel includes distortions resulting from attacks and may include interference from the original digital data. Most current techniques for embedding digital watermarks in multimedia (e.g., audio, images, video, etc.) are based on spread spectrum (SS), although the connection is not… CONTINUE READING
