摘要

Image steganographic communication demands a fair trade-off among the threediametrically opposed metrics such as higher capacity, larger visual quality, andattack survival ability (ASA). Recently, some reversible data hiding (RDH) techniquesusing dual images have shown promising results to achieve the aforementionedneeds. However, maintaining a balance among these metrics is still an openchallenge. In this paper, using the concept of shadow image, which is basically thereplica of the cover image (CI) and performing some simple addition and subtractionlogic on the shadow image pixels, we propose an improved RDH techniquethat offers larger capacity, better stego-image (SI) quality and higher ASA. At first,during embedding, three shadow images of the CI are produced. Then, the shadowimage pixels are adjusted based on their XOR features of the least significant bitplanes. After embedding the secret bits, a maximum of ± 1 modification has beenobserved in the SI pixels. Later at the receiving end, the CI has been restored byapplying the round function on the obtained SI pixels. Experimental results showthat the proposed technique offers excellent visual quality with peak signal-to-noiseratio and structural similarity index (SSIM) of 52.47 dB, 53.91 dB, 52.48 dB and0.9974, 0.9981, 0.9974 for the respective shadow images. Further, the proposedtechnique show exceptional anti-steganalysis ability to regular and singular analysis,pixel difference histogram analysis, and bit pair analysis. Additionally, the proposedtechnique successfully avoids the falling-off boundary problem.
