Which type embeds hidden messages in a digital sound format?

• A. Video Steganography
• B. Document Steganography
• C. Whitespace Steganography
• D. Audio Steganography

Answer: (D)

Hiding messages inside a digital sound format relies on concealing data within audio data itself without changing what the sound sounds like to a listener. This is Audio Steganography. Techniques such as modifying the least significant bits of audio samples or embedding data through subtle echoes or spectral tweaks let a sound file carry a secret payload while still sounding normal. A WAV or MP3 file can thus conceal information for covert transmission or watermarking. Video steganography would hide data in video data (frames, color channels, compression artifacts), document steganography hides data within document formats or metadata, and whitespace steganography hides data in the arrangement of spaces or line breaks in text.
