Steganography is a word originating with the Greeks meaning ‘covered writing’. Its use can be traced back at least 2,500 years, when Demaratus smuggled a secret message under the cover of wax in order to warn Sparta of an impending attack on Greece. Other examples used throughout history include invisible ink, nullciphers, and microdots.
