Which tool can hide data within a cover file (e.g., images) and watermark images with an invisible signature to detect unauthorized copying?

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

Answer: (C)

Hiding data inside a cover file and watermarking it with an invisible signature is a form of steganography used for both concealment and copyright protection. OpenStego is designed to do exactly that: it can embed a payload inside an image or other cover file and also apply an invisible watermark to the same image. The embedded data is protected by a password, and the watermark provides a detectable signature that can be extracted later to prove ownership or detect unauthorized copying. This combination makes OpenStego the best fit for scenarios where you want to both hide information and enforce copyright by proving provenance. Other tools may offer either data hiding or basic steganography, but they don’t consistently pair data concealment with robust watermarking for copyright protection.
