Complete complementary code can be applied to digital watermarking technologies as well as communication systems like approximately synchronized CDMA because of its good correlation properties. In this paper, we propose a blind watermarking algorithm which does not need to refer any original data in the watermark extraction process. We also discuss the analogy between the proposed watermarking scheme and CT-CDMA communication systems based on complete complementary codes. In addition, some extensions of the proposed watermarking method and future problems are discussed in the paper.
