1. A computer-implemented method of securely transmitting communication information over an insecure communications channel from a first terminal operating in a first coordinate measurement domain to a second remotely-located receiving terminal operating in a second coordinate measurement domain, the communication information relating to information defined by a user for communication to the second remotely-located receiving terminal, the method comprising:

  • selecting extraneous information for use in creating a data signal, the extraneous information relating to information that does not form a part of the information defined by the user;

    prior to transmission of the communication information from the first terminal, combining, with a processor of the first terminal, the communication information with the extraneous information to create the data signal, the communication information being concealed with the extraneous information within the data signal;

    determining, with the processor of the first terminal, a value of an identification variable expressed with respect to the first coordinate measurement domain, the value of the identification variable enabling a location of the communication information concealed within the data signal to be determined;

    transmitting the data signal and the value of the identification variable from the first terminal to the second remotely-located receiving terminal;

    using a coordinate transform function configured to map coordinate values from the first coordinate measurement domain to the second coordinate measurement domain to calculate a value of the received identification variable expressed with respect to the second coordinate measurement domain; and

    extracting the communication information from the received data signal using the value of the calculated identification variable to distinguish the communication information from the extraneous information;

    wherein the first terminal is provided with the coordinate transform function and uses the coordinate transform function prior to transmitting the data signal;

    the communication information is transmitted to the second receiving terminal operating in the second coordinate measurement domain and to a third receiving terminal operating in a third coordinate measurement domain;

    the second coordinate measurement domain is associated with the first coordinate measurement domain by a first coordinate transform function;

    the third coordinate measurement domain is associated with the first coordinate measurement domain by a second coordinate transform function;

    the first coordinate transform function is used to calculate a value of the identification variable expressed with respect to the second measurement domain; and

    the second coordinate transform function is used to calculate a value of the identification variable expressed with respect to the third coordinate measurement domain.
