Abstract:


We use Linear error-block codes (LEBC) to design a new method of gray-scale image steganography. We exploit the fact that in an image there are bits that better hide distortion than others (not necessarily least signi_cant bits). Our method uses the cover bits as extensively as their ability to hide distortion. The results show that with a good choice of parameters, the change rate can also be smaller.
