Steganography vs. Cryptography
*Steganography’s goal is to keep the presence of a message secret, or hide the fact that communication is taking place *Cryptography’s goal is to obscure a message or communication so that it cannot be understood *Steganography and Cryptography make great partners.  It is common practice to use cryptography with steganography
•Steganography is NOT the same thing as cryptography.
•Steganography is used to hide the presence of a message or communication, whereas cryptography is used to obscure a message or communication so that it cannot be understood.
•It’s common practice to use cryptography to obscure a message prior to using steganography to hide it.
