摘要：

This paper proposes an efficient reversible information hiding scheme to improve A lattar et al. 's integer transform function hiding scheme, which needs a location map to recover the original image. The proposed scheme uses four pixels in the nearby area to embed three message bits. The differences between neighboring pixels are expended to conceal the secret bits.
