Digital watermarking technologies with spread spectrum sequences (SS) have previously proposed.However, the SS sequences used in previous studies do not necessarily have good correlation properties.The previous studies also have proposed the complete complementary codes (CCC), which have an ideal auto-correlation and cross-correlation properties and methods for the construction and extension of the complete complementary codes.However, some methods in the studies do not have good auto-correlation or crosscorrelation properties.In this paper, we used the latest complete complementary code constructor to detect the embedded secret information from the watermarked images.In the experimental results, we successfully detected the secret information from the watermark against various attacks.
