Abstract
A method for embedding a watermark signal that contains message data in a digital image represented as a two-dimensional array of pixel values, includes the steps of: providing a dispersed message image having pixel values representative of the message data; modifying each pixel value of the dispersed message image as a function of the corresponding pixel value in the digital image; and combining the modified dispersed message image with the digital image to produce a watermarked image.
