Study on Hidden Confidential Information of Remote Sensing Images Based on Arnold Transformation and Chaotic Encryption

DUAN Xiao-ying,WANG A-chuan (College of Information and Computer Engineering, Northeast Forestry University,Harbin Heilongjiang 150040,China)  
Currently,digital watermarking technology is quite mature,but the reports on the confidential information hiding technology of remote sensing images are rare.Some confidential information of remote sensing images is invisible to the users without permission,so therefore,we need to use information hiding technology to hide confidential information.A hiding algorithm of confidential information based on Arnold transformation and chaotic encryption technology is presented The algorithm first uses Arnold transformation and chaotic encryption technology to encrypt confidential information and then uses the information hiding algorithm based on DWT transformation to hide the confidential information in the pseudo-remote sensing images.The experimental results show that the confidential information of remote sensing images can be effectively hidden by the algorithm which protects the security of the confidential information,so hiding confidential information in remote sensing images plays an important role in information security.
