An Efficient Reversible Information Hiding Scheme Based on Interval Expansion

Abstract: Reversible information hiding technique not only can effectively embed secret message into a host image, but also can completely remove the concealed message to recover the original media. This technique has been widely used in medical and military areas. Because these two areas not allow any error and the reversible information hiding technique is suitable for the request. Its practicability and significant make the reversible information hiding technique to become an important research issue. This paper proposes an efficiency reversible hiding scheme based on interval expansion. The proposed scheme expands the interval between pixels to embed information in an image. The receiver can extract the concealed message and restore the original image from the stego image.
