种基于Data Matrix的数字水印算法

摘要

A new image covert communication method based on digital watermarking was put forward. The algorithm encodes the communication information by using the data matrix bar code technology to generate the bar code image. As the original watermarking information, the generated image is embedded into the carrier image after being transformed and scrambled properly. Experimental tests show that the proposed scheme is robust against geometric distortions and other common signal processing techniques. More importantly, the algorithm ensures the accuracy of telecommunication.%提出一种基于数字水印的图像隐秘通信方法。该算法首先运用Data Matrix条形码技术对具有含义的通信信息进行编码，生成条形码图像。生成的条形码图像作为原始水印信息，在经过适当的变换和置乱之后将其嵌入到载体图像中。结果表明，该方法具有良好的不可见性和鲁棒性，能抵抗旋转、缩放、滤波等攻击，更为重要的是较好地保证了通信信息的正确性。
