Robust Reversible Data Hiding for Multispectral Images

A robust reversible data hiding scheme for multispectral image is proposed in this paper. Different from the existing robust lossless data hiding schemes which use statistical quantity of the arithmetic difference of image blocks, this method shifts transform domain statistical quantity histogram to get a better performance for multispectral images. The statistical quantity of the average of the coefficients in 3D-IWT (Integer Wavelet Transform) block is used to embed data and to achieve robustness. The secret message can be extracted without a location map or overhead information. The experimental results demonstrate that the robustness and embedding capacity of the proposed scheme outperform the representative method in literature.
