Which term is the method of concealing a message within another object?

• A. Risk Management
• B. Security Requirements Traceability Matrix (SRTM)
• C. Stakeholders
• D. Steganography

Answer: (D)

Steganography is the technique of concealing a message inside another object. The secret data is embedded in a cover medium—such as an image, audio file, video, or document—in a way that the overall object appears ordinary, so the hidden message remains undetectable to casual observers. The goal isn’t to make the content unreadable (that’s encryption); it’s to hide the very existence of the message. In practice, information can be tucked into subtle parts of the cover medium, like the least significant bits of pixel values or unused metadata, so only someone with the right method can retrieve it. This concept is distinct from terms like risk management, which deals with handling potential threats, or stakeholders, who are people involved in a project, because steganography specifically focuses on hiding information rather than planning or people.
