Digital watermarking algorithm based on complete complementary code

This paper proposes a watermarking algorithm to embed the watermark into the original image by using Complete complementary code method. Spread spectrum communication systems use the spread sequences that have good correlation properties. Complete complementary code (CCC) is a set of spread sequences, and has an ideal auto- and cross- correlation properties. Watermark extraction procedure has also been dealt with. It is found that the algorithm implementation on various 24 bit color images have proven that the strength of the algorithm is as required.
