Which tool provides Data Hiding and Watermarking to detect unauthorized file copying?

• A. OpenStego
• B. Snow
• C. Steganography Master
• D. Spam Mimic

Answer: (B)

Data hiding and watermarking work together to protect content by embedding a hidden payload and a visible or extractable mark into the file. Snow is a steganography tool that specializes in embedding data inside digital media and also supports watermarking, which lets you attach an ownership mark to the file. This makes it possible to detect unauthorized copies because the watermark can be verified even after the file is distributed. That combination—secret data embedding plus an identifiable watermark—fits the scenario of detecting unauthorized copying more directly than tools that focus on other forms of hiding or don’t emphasize watermark-based ownership proof.
