it discusses several information hiding methods useable for steganographic communication, among them substitution systems, hiding methods in two-color images, transform domain techniques, statistical steganography, distortion and cover generation te
Steganography is the art of hiding information within other information in such a way that it is hard or even impossible to tell that it is there. There are many different carriers for steganography but the most popular is digital images. Recently,
This paper presents a method to detect the quantization index modulation(QIM) steganography in G.723.1 bit stream.We show that the distribution of each quantization index(codeword) in the quantization index sequence has unbalanced and correlated char
