Technical Steganography is best described as which of the following?

• A. Encryption of message
• B. Physical or chemical means to hide existence of message
• C. Hiding by creating randomness
• D. Hiding by compressing data

Answer: (B)

Hiding the existence of a secret message is the essence of steganography. Unlike encryption, which scrambles the content so it’s unreadable but the fact that a message is present is obvious, steganography aims to conceal that there is any message at all by embedding it in another medium. When we refer to technical steganography, we emphasize physical or chemical methods—like invisible ink, microdots, or other covert means—that hide the secret within the carrier itself. The other ideas describe encrypting the content or hiding it in ways that don’t necessarily conceal that a message exists, such as adding randomness or compressing data.
