Baconian cipher

The Baconian cipher, or Bacon's cipher, is a method for steganography invented by Francis Bacon in 1605. Each letter is translated into a pattern of five digits or the letters 'A' and 'B'. These are then applied to a carrier message. For instance they could represent two different typefaces or some other property of the letters.

For example the letter F would translate to aabab. We could apply it to the word 'horse' by letting a = lowercase and b = uppercase. We then get hoRsE. This way of applying the cipher is very easy to detect, but is a good example. There are countless other possibilities in how to apply it.
