| 摘 要： | 提出了一种增强数字水印系统鲁棒性的数字水印技术。算法将标识信息编码为快速响应矩阵码(QR码),将其作为数字水印,利用离散小波变换方法将QR码嵌入到了载体图像二级小波分解后的中频系数中,在保证水印不可见性的前提下能增强水印的鲁棒性。设计了对比实验,实验结果表明,将QR码作为数字水印,能增强水印安全性和鲁棒性,且该方法适用于任何水印算法。

| Abstract: | A digital watermarking technology was put forward,which can enhance the robustness of digital watermarking system.This method encodes the watermark information as quick response code(QR Code) and embeds the QR code as a digital watermark into the intermediate frequency of the digital image by two discrete wavelet transform.This method increases the robustness under the premise of invisibility.Comparative experiment was carried out and the results showed that QR code as a digital watermark increases the security and robustness,and is applicable for any kind of watermarking algorithm. |

| Keywords: | quick response code digital watermarking discrete wavelets transform robustness |
