Differences between Steganography and Watermarking

Watermarking and steganography differ in an important way: Steganographic information must never be apparent to a viewer unaware of its presence; this feature is optional when it comes to watermarking.

Modern steganography should be detectable only if secret information is known, namely, a secret key.
