The advantage of steganography over cryptography alone is that steganographic message does not attract attention to communicating parties. An apparent encrypted message‚ no matter how unbreakable it is‚ can arouse suspicion and may in itself be incriminating. If suspicion is raised‚ then the goal of steganography is defeated. Since there is always a possibility that secret communication will be uncovered‚ steganography is often used together with cryptography. A steganographic message (the plaintext)

Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying
