In acting, substitution is the understanding of elements in the life of one's character by comparing them to elements in one's own life. For example, if an actor is portraying a character who is being blackmailed, they could think back to some embarrassing or private fact about their own life, and mentally superimpose that onto the character's secret.
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
Marlon Brando's performance in Elia Kazan's film of A Streetcar Named Desire exemplifies the power of Stanislavski-based acting in cinema. [1]Method acting, known as the Method, is a range of rehearsal techniques, as formulated by a number of different theatre practitioners, that seeks to encourage sincere and expressive performances through identifying with, understanding, and experiencing a ...
In a polygraphic substitution cipher, plaintext letters are substituted in larger groups, instead of substituting letters individually. The first advantage is that the frequency distribution is much flatter than that of individual letters (though not actually flat in real languages; for example, 'OS' is much more common than 'RÑ' in Spanish).
A visual example of attribute substitution. This illusion works because the 2D size of parts of the scene is judged on the basis of 3D (perspective) size, which is rapidly calculated by the visual system. In 2002 Daniel Kahneman and Shane Frederick proposed a process called attribute substitution which happens without conscious awareness.
Transposition is often combined with other techniques such as evaluation methods. For example, a simple substitution cipher combined with a columnar transposition avoids the weakness of both. Replacing high frequency ciphertext symbols with high frequency plaintext letters does not reveal chunks of plaintext because of the transposition.
Counterconditioning (also called stimulus substitution) is functional analytic principle that is part of behavior analysis, and involves the conditioning of an unwanted behavior or response to a stimulus into a wanted behavior or response by the association of positive actions with the stimulus.

Alternative techniques included inserting microdots into slits cut into the edge of postcards. Printing introduces noise in the ciphertext, at times rendering the message unrecoverable. There are techniques that address this limitation, one notable example being ASCII Art Steganography. [4] Yellow dots from a laser printer
