中文摘要:
      目的 为了提高QR码的抗打印扫描能力,提出一种抗打印扫描的双彩色QR码水印算法。方法 将彩色载体QR码分通道,并对各通道进行三级小波变换和SVD分解,将置乱后彩色水印图像分通道嵌入到对应载体图像特征矩阵中,利用DWT-Schur分解嵌入标记矩阵的方法解决SVD分解带来的虚警率问题。结果 实验表明,该算法在100%识别的情况下,具有较好的抗打印扫描能力。结论 该算法不仅具有较好的抗打印扫描能力,且解决了SVD分解带来的虚警率问题,同时对裁切、旋转和JPEG压缩等攻击具有较好的鲁棒性。
英文摘要:
      The work aims to propose a double color watermarking algorithm with QR code for anti-print scanning to improve the anti-print scanning ability of the QR code. Firstly, the color carrier QR code was divided into several channels, and each channel was processed by three-level wavelet transform and SVD decomposition. Then, the channels of the scrambled color watermark image were embedded into the corresponding carrier image feature matrix, solving the problem of false alarm rate brought by SVD decomposition with DWT-Schur decomposition embedded into the mark matrix. The experiments showed that, the algorithm could be completely identifiable (100%) and had good anti-print scanning ability. The algorithm not only has good anti-print scanning ability, but also solves the problem of false alarm rate caused by SVD decomposition, and it has good robustness to the attacks such as cropping, rotation and JPEG compression.
