Abstract

An improved steganographic method is proposed in this paper. Two distinct methods are combined here with optimized way with possibly high data hiding capability. The proposed method shifts the last nonzero AC coefficients in each JPEG block, and, changes the magnitude value of the first nonzero AC coefficients.
