Executive Summary

How to make the Information Hiding scheme have a better performance in terms of invisibility, robustness, sensitivity and anti-steganalysis becomes a research hotspot. Currently, the algorithm has not achieved four performances at the same time. The scheme based on space domain are good at invisibility, but can not meet the requirements of robustness and anti-steganalysis at the same time. The scheme based on transform domain are good at robustness. Zhang et al and Zhu et al proposed Information Hiding scheme and digital watermarking scheme respectively based on Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT).
