  • Communication between a human user and a computer resistant to automated eavesdropping
    Publication number: 20090125994
    Abstract: Communication between a human user and a computer over an insecure channel is accomplished by encoding user input using one or more character substitution tables. The character substitution tables are transmitted to the user over the insecure channel in a perceptually modified form which renders them difficult for use by automated adversaries but keeps them easily understandable by humans.
