1. One possible way to encode information in text is print it in two slightly different typefaces. The secret message is decoded by ignoring one of the typefaces. Below is an example with very different typefaces for clarity. Jam and jelli e s are j ust o rdinar y c r e ature comforts  James joyce This clever idea dates back to Francis Bacon. However it will not work unless the original physical text is preserved

2. There are however, methods to encode messages into the symbol values of the text itself, thus guaranteeing the propagation of the message to any (faithful) copy. Consider this example that was actually sent by a German Spy in WWII: Apparently neutral's protest is thoroughly discounted and ignored. Isman hard hit. Blockade issue affects pretext for embargo on by products, ejecting suets and vegetable oils.

Consider this example that was actually sent by a German Spy in WWII: Apparently neutral's protest is thoroughly discounted and ignored. Isman hard hit. Blockade issue affects pretext for embargo on by products, ejecting suets and vegetable oils. By taking the second letter in each word the following message emerges:  Pershing sails from NY June 1.

4. A more sophisticated variation on the same basic idea is to embed the message by a technique of Equidistant Letter Sequences (ELS). The idea is to imagine the text as a continuous string of characters, with all punctuation and spaces removed. To decode a message of length K, start at the N th place and read off every D th letter. As an example we have encode the name James in (4) below using an N value (often called the Offset) of 7 and a D value (often called the Skip) of 4. Why not just ask?
