Which statement best describes steganography?

• A. Encrypting the content of a message
• B. Compressing to save space
• C. Hiding the existence of a message within another medium
• D. Blocking message delivery

Answer: (C)

Steganography hides a secret message inside another ordinary medium so that the existence of the message itself goes unnoticed. It’s different from encryption, which scrambles the content so it can’t be read but still makes it clear that a message exists. In steganography, the hidden data is embedded in a carrier—like an image or audio file—so casual observers don’t realize anything is there. A common example is embedding data in the least significant bits of image pixels, which can carry information without noticeably altering the image. The other ideas describe methods that don’t conceal the presence of data: encryption only protects the content, compression reduces size, and blocking delivery stops the message from being transmitted.
