Semagrams


A semagram is nothing more than a symbol. Its literal meaning is, in fact, semantic symbol. Semagrams are associated with a concept and do not use writing to hide a message. Do you remember our example in the Prisoners' Problem? Bob sent a picture to Alice; the picture or, more specifically, characteristics about the picture conveyed the secret information. A semagram can be almost anything that does not use words to hide a message. You will see more on semagrams when I cover World War II in the next section.
