An Improved Data Hiding Method Using Image Interpolation

Abstract

Reversible data hiding method enables to recover the cover image after the secret data were extracted. Recently, a reversible data hiding method based on image interpolation has been proposed. It can contain high capacity and keep good visual quality. In this study, an improved method has proposed to refine the interpolation image based method. Experimental results revealed that the proposed method has the same capacity and promoted the quality of stego-image when compared with the origin method.
