摘要
地理空间情报在情报分析与作战指挥中发挥了越来越重要的作用,能有效隐藏加密图像条件下保证地理情报中加密信息的安全性。针对能有效隐藏和有效准确还原情报及图像安全问题,并为了实现安全保护,提出了一种遥感影像中机密信息隐藏算法,算法基于遥感影像融合且能够进行遥感影像中机密信息不同程度的隐藏,有效地提高了信息的安全性。实验结果表明,算法具有较强的隐藏性,为地理空间情报分析提供了科学参考。
In intelligence analyses and command of wars, GeoINT which contains remote sensing image and geographical information takes a more and more important place. How to effectively hide it under the conditions of en- crypted image to ensure geographic information security level is the focus of the image area of security research. In or- der to achieve information security protection, this paper proposes an algorithm for secret information hiding in remote sensing images based on different authorities, and it is based on remote sensing images fusion and can achieve bidding to different degrees of the secrete information according to different authorities of users. It can effectively improve the security of information. The results show that the algorithm has strong hidden ability.
