Which type hides data by embedding it into a video file?

• A. Video Steganography
• B. Web Steganography
• C. Spam/Email Steganography
• D. Folder Steganography

Answer: (D)

Hiding data inside a video file is video steganography. The secret payload is embedded within the video data in a way that keeps playback looking normal, often by manipulating the least significant bits of pixels across frames or by using parts of the video’s compression artifacts. This carrier—video—provides a large amount of data space to conceal information without drawing attention. Other approaches involve different carriers: folder steganography hides data by exploiting the file system structure or folder metadata, not by altering the video content; spam or email steganography hides data within the content or metadata of messages, while web steganography hides data within web content or traffic. The key idea is that the hidden data rides inside a different medium, but only video steganography uses the actual video data as the concealment channel.
