Which type hides information by embedding data in signs or symbols to convey predetermined meaning?

• A. Semagrams
• B. Text Semagrams
• C. Open Codes
• D. Jargon Codes

Answer: (A)

The main idea is that the hidden message is carried by signs or symbols whose chosen arrangement conveys meaning only to someone who knows the code. Semagrams work by using a defined set of signs, where each sign or a specific sequence of signs maps to data. When the signs are arranged in a particular way, they represent bits, letters, or other information, so the intended recipient can decode the predetermined message even though to outsiders the signs look ordinary. This is a covert signaling method that relies on the agreed-upon meaning of each symbol and how they combine, rather than on hidden text or obvious coded words. Text variations exist, but the core concept remains: information is embedded in the signs themselves, not in the surface content.
