Conclusion

In this paper we presented a new transform domain data hiding scheme used for steganographic applications such as covert communication or captioning. The technique embeds high data rate by scrambling the cover image which results in transform coefficients which occupy the entire image spectrum. We showed that the technique is secure by showing that both the perceptual quality and the statistical properties of the cover and the stego image are both identical. Furthermore, the hidden information cannot be extracted unless one has access to the scrambling key. Future work will concentrate on improving the robustness of the technique and on estimating the capacity of the cover image to increase the data embedding rate.
