Abstract :
In this paper, we propose an efficient EMD-based data hiding scheme. To avoid the serious, but usually disregarded, overflow problem in the embedding process, the danger cover pixels, which may result in overflow problem, are modified to safe area. However, the modification will not influence the stego image quality. Comparing to Hong et al.´s scheme proposed in 2008 and Lee et al.´s scheme proposed in 2010, our proposed scheme outperforms these two previous scheme in stego image quality.
