Abstract

This paper proposes a new technique for information hiding based on morphing technology. In the proposed technique, the morphing image (stego image) is generated with warping of the source image (embedded data) by morphing. This corresponds to embedding of data in conventional information hiding. Therefore, the cover data which is necessary in conventional information hiding is unnecessary. Also, information of the source image appears on the morphing image which corresponds to the stego data according to the morphing rate. Besides extracting the embedded data from the stego image, it is also possible to use the stego image alone. In this paper, we first show that the morphing technology can be used as an information hiding technique, and then describe the features of the proposed technique as compared with the conventional techniques for information hiding. Finally, an application is introduced.
