Abstract :
It has been shown that complete complementary codes can be applied into CDMA communication systems because of its good correlation properties. A digital watermarking scheme using complete complementary codes has also been proposed. In this watermarking scheme, it is possible to embed the multiple secret data in a single image at the same time, but the effectiveness and the limit of the method has not been fully explored. In this study, the properties of the watermarking method are analyzed when the multiple secret ID´s are embedded into a single image simultaneously. The paper also includes the discussion on the extension to a kind of steganography.
