Steganography is defined as which of the following?

• A. Hiding a secret message in some other message
• B. Authenticating users
• C. Encrypting a message with a key
• D. Compressing data

Answer: (A)

Steganography is the practice of concealing a secret message inside another ordinary-looking message or medium so that the hidden communication remains undetectable. This focus on hiding the very existence of the secret makes it the correct concept here. For example, you might embed data in the least significant bits of an image or hide information inside an audio file, so the carrier appears normal to casual observers. In contrast, authenticating users is about verifying identity, encryption with a key is about scrambling the content so it’s unreadable without the key, and compression reduces size. None of these primarily aim to hide the presence of a secret message, which is the essence of steganography.
