Abstract: This paper introduces the principle and application methods of digital watermarking and gives an watermarking algorithm of the digital image which is based on discrete cosine transformation (DCT). According to the actual research, the paper systematically analyzes the algorithm. With Matlab programming tools, this algorithm has realized the embedding and extracting of the digital watermark. And the paper proceeds a attack test to the image. The research confirms that DCT digital watermarking algorithm has better robustness.
