## A Practical Blind Algorithm for Two-Dimensional Secrete Information Hiding in Remote Sensing Image

• 摘要: 提出了一种实用的二维信息隐藏盲算法,以实现遥感影像中机密信息的隐藏。

Abstract: In order to hide secrete information in remote sensing image, this paper proposes a practical blind algorithm. Firstly, we segmente and extract the secrete information in remote sensing image, then make gray value supplement in the area in which the secrete information has been extracted, and produce the disguised remote sensing image in which the secrete information is wiped off. Then we use for reference the idea of information hiding and utilize the algorithm of odd-even embedding to embed the secrete sub-image imperceptibly into the disguised remote sensing image to produce the disguised one in which there hides secrete sub-image. In addition, during the course of extracting secrete information and resuming the remote sensing image, this algorithm does not need the original remote sensing image and is a blind one. Experimental results show that this algorithm is not only quite transparent and has a good effect on large amount of secrete information hiding, but also has a strong robustness against such familiar image processes as JPEG lossy compression, noise adding, scaling and cropping. Furthermore, this algorithm has no influence on various applications of the disguised remote sensing image with the hidden secrete information.
