Advantage over Cryptography:

The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny.

Means :Plainly visible encrypted messages—no matter how unbreakable—will arouse interest

Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message.
