Firstly, a secret message of an arbitrary plain text is encrypted, compressed and transformed into a stream of bits. Subsequently, the bits are converted into secret digits by using the Huffman dictionary table. Secondly, a cover image is segmented into groups of n pixels and each group is embedded with one secret digit by modifying one gray-scale value at most to hide the secret digit in (2n+1)-ary notational system. The experimental results have shown that both PSNR and payload of the proposed method are higher than that of well-known methods namely, OPAP, EMD and Opt EMD.
