ABSTRACT:
A digital image watermarking method is provided. The digital image watermarking method includes the steps of combining host image data sets and signature image data sets by a predetermined method for combining the sets to be linearly independent, and generating a watermarked image and a key from the combined image. A signature image embedded in a combined image is similar to the combined image in view of existence and durability.
