Abstract

Difference Exapansion is one of popular reversible steganography methods which can be used for authenticating images. By using this method, the reconstructed image is exactly the same as the original one. However, the stego image generated is relatively different from the original. Based on Quad and RDE methods, we propose an algorithm which can improve the quality of the stego image, in terms of PSNR, in particular. The experimental results show that while the capacity of embedded message is slightly higher, the PSNR is significantly better.
