中文摘要：

针对遥感影像数据,提出一种基于快速响应矩阵（QR）码的抗剪切与噪声攻击的强鲁棒性盲水印算法.首先,利用版权认证信息生成QR码水印图像;然后对QR码水印图像执行Arnold置乱并引入纠错编码机制对水印图像进行预处理;最后结合遥感影像的数据特点选择合适的嵌入强度和嵌入位置进行水印嵌入.水印检测是水印嵌入的逆过程,可采用多数原则进行水印信息位的提取和自纠错.QR码的引入有效提升了水印信息容量,同时也增强了整个水印系统的鲁棒性.嵌入的水印信息在保持遥感影像精度和统计特性的前提下具备良好的不可见性,且能抵抗高强度的剪切攻击和噪声攻击.

英文摘要：

A blind watermarking algorithm with strong crop and noise resistibility based on quick response（ QR） code for remote sensing image was presented. Firstly,QR code image is generated by use of copyright authentication information. Secondly,the QR code image is scrambled based on Arnold transforms,while the error-correction coding method is introduced to pretreat the watermark image. Finally,considering the properties of the data of remote sensing image,the appropriate strength and position are selected to embed watermark. Watermark detection is the inverse process of embedding watermark. Watermark detection is the inverse process of embedding a watermark,and the majority rule is used to extract and self-correct the watermark information bits. The introduction of QR code effectively enhances the capacity and robustness of the watermark information. Embedded watermark based on the premise of keeping the accuracy of features and statistical properties of remote sensing images was studied. The embedded watermark is not only of good invisibility,but also of strong crop and noise resistibility.
