| Abstract: | Digital watermarking is an effective method in the copyright protection of digital products.With research work on secret image embedding and extracting technology based on DCT algorithm,this paper puts forward an image watermark embedding and checking technology.In this approach,the 2D watermarks are embedded into the DCT middle frequency with modular arithmetic.The experimental results show that this technology meets the demand of robustness under the attack of compress and noise. |
