Abstract:

Image hiding involves the concealment of an embedded secret image within a cover image to form a stego-image. The secret image can be used for transmission across the public networks without its presence being detected. Image hiding thus serves as a way of secure message communication; therefore, except for the platitudinous issues of image quality and hiding capacity, it is necessary to pay more attention to the means to assure the origin and integrity of the delivered content. In this paper, a digital signature scheme is skillfully applied so as to guarantee the integrity and the origin of the transmitted message and a behind-the-scenes guide to recover the hidden secret. Our idea launches realistic feints and ambushes to enhance the effect of camouflage.
