Paper Abstract

In this paper, we introduced information hiding technique into remote sensing area, proposed its characters, requirements and difference from general information hiding technique and illuminated that general image hiding algorithm doesn't adapt to remote sensing image. We developed the connotation of information hiding that the secret information is still hidden in the original remote sensing image and proposed a practical information hiding technique for multi-spectral remote sensing images and a wavelet information hiding algorithm adapting to the features of the multi-spectral remote sensing image based on DWT embedding strategy and HVS character. The experimental results show that the information hiding technique and algorithm for multi-spectral remote sensing images proposed in the paper not only has the advantages of good transparency, strongness, large information capacity, correct extraction of secret, well protecting the textural and spectral features of the secret ground object and vividly resuming the multi-spectral remote sensing image, but also has a strong robustness against JPEG lossy compression and noise adding. Furthermore this algorithm has no influence on applied value of a multi-spectral remote sensing image, doesn't need the original image while extracting the secret information and resuming the original one and was a blind algorithm.
