I headed to the library to check out what they had, crypto-wise. I found one book copyright 1939, which had a chapter on methods of steganography. Some of the suggestions I got from it: -Use every third letter of each word. -Use every nth letter of each word, where n varies depending on a key. (e.g., 2-4-1-5-5-3) -use every nth word of a sentence. -encode in base-3 before steganizing. -use the number of syllables in a word. -use the number of words in a sentence. Irrelevant suggestions: -use different fonts. (within the same word.) -use broken and whole pickets in a fence. -use empty and full positions in a cartridge-belt, as in machine gun. -use invisible ink instead, it's easier. :-) Maybe these will help those more able to program than myself.
