Information hiding using image interpolation was first introduced by Jung and Yoo in 2009, where one original image is expanded to by neighbor mean interpolation, and this expanded image is called cover image. The secret information can be then hided into those inserted pixels in this cover image, where the image with embedded secret information is called stego image. Recently Yang et al. adopt OPAP and LSB substitution in image interpolation, and construct a new data hiding scheme. This new data hiding scheme can improve stego image's quality of Jung-Yoo's work. However, the approaches of LSB and OPAP substitution are vulnerable with RS detection, which causes a serious secure problem. In this work, we construct a new image interpolation based information hiding scheme by using GEMD and RGEMD information hiding methods. The combination of GEMD (RGEMD) and image interpolation could not only resist RS detection, but also improve stego images' quality from Yang et al.'s scheme.
