Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605.[1][2][3] In steganograhy, a message is concealed in the presentation of text, rather than its content. Baconian ciphers are categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces).
