Two Improved Data Hiding Schemes

摘要：

The meaning of data (information) hiding is to embed the secret information into a cover host, such as an image. Usually, the naked eye of the people cannot perceive any change when the image is modified slightly. The evaluation of data hiding schemes should be measured by the distortion (or called Mean Square Error; MSE) and the embedding rate (the average number of bits embedded in a cover pixel). In this paper, we propose two improved data hiding schemes. One is to improve the EMD (Exploiting Modification Direction)-based data hiding algorithm to have higher stego-image quality. The other is to improve the Matrix encoding-based data hiding algorithm by using the idea of Hamming+1 to further improve the stego-image quality. Both proposed improved schemes are verified to be correct through the theoretical analysis and the experiment.
