Which type embeds the content in audio and graphical data?

• A. Video Steganography
• B. DVD-ROM Steganography
• C. Web Steganography
• D. Hidden OS Steganography

Answer: (B)

Embedding content in audio and graphics goes beyond just a single media stream; it leverages the container that carries both audio and video/graphics data. A DVD-ROM holds multimedia content as video with accompanying audio streams and graphic streams (subtitles, menus, etc.) within its VOB structure. Steganography at the DVD-ROM level targets those multimedia payloads inside the disc, letting data ride inside the same audio/visual data that users expect to see and hear. That makes DVD-ROM Steganography the most fitting way to conceal information in a medium that inherently contains both audio and graphical data. In contrast, general video steganography focuses on hiding data within video frames themselves, which is related but is not tied to the DVD medium specifically. Web steganography hides data in web content like HTML or images on the web, and Hidden OS steganography hides data within an operating system’s components.
