A Secure Watermarking by Chaotic Function abstract
In this paper a secure watermarking system is proposed. Instead of embedding the original watermark into the cover image like the normal watermarking systems, the proposed system creates a chaotic sequence and embeds DCT transform of the original watermark via this sequence into the cover image, so the method is named Chaotic DCT Watermarking ,CDW. Another sequence is used to encrypt the coefficient of DCT. To reveal the original watermark, the correct keys are required. Simulation results show the higher security and lower memory can be achieved by the proposed method.
