Which technique hides information with the help of signs or symbols embedded in the data to change its appearance to a predetermined meaning?

• A. Visual Semagrams
• B. Text Semagrams
• C. Semagrams
• D. Linguistic Steganography

Answer: (C)

Semagrams hide information by embedding signs or symbols into data so that the data’s appearance aligns with a predetermined meaning when decoded. This approach uses those embedded signs to convey a covert message while the overt content looks normal. Visual semagrams (in images) and text semagrams (in text) are specific forms, while linguistic steganography relies on language features rather than embedded signs in the data itself. The description fits semagrams best because it centers on embedding signs or symbols within the data to change its interpretation to a hidden meaning.
