Abstract:


In this paper, a simple reversible least-significant-bit (LSB) matching algorithm, which can completely recover the host images without any distortion from the stego images by utilizing the parity features of the host images and defining two embedding pairs. It embeds hidden message via LSB matching instead of LSB replacement, which makes it immune to steganalytical attacks utilizing the imbalance introduced by the LSB replacement. Multiple layer embedding is also allowed for the proposed method, and it won’t decrease the PSNR of the stego images. The average PSNR of the stego images generated by the proposed method is 51.14dB. Experimental results show the proposed algorithm has better performance than existing reversible LSB modification in terms of distortion, visual quality, capacity as well as resistance against existing steganalytic detectors.
