Steganography is the technology of hiding messages in such a way that no one except the authorized recipient knows the existence of the messages. In steganography, a message is hidden in some cover message. The larger the cover message is relative to the hidden message, the easier it is to hide the latter. When the hidden message is an image, it is difficult to hide the message into another image unless the size (in number of bits) of the hidden image is much smaller than that of the cover image. To solve this problem, this paper proposes a novel steganographic technique based on image morphing. The basic idea is to transform the hidden image into a morphing image, and use the morphing image as the stego message. The authorized recipient can recover the hidden image from the morphing image through demorphing. The morphing image can also be used directly for certain purposes.
