1. A method of securely communicating a message to an individual, the method comprising:
receiving, using a first data channel, first data that comprise an encryption of a first portion of an encoding of the message using an individually secure code with a generator matrix;
receiving, using a second data channel, second data that comprise a second portion of the encoding of the message using the generator matrix, wherein the first data channel and the second data channel comprise different transmission media and wherein receiving the first message or receiving the second message comprises correcting one or more errors;
decrypting the first data to retrieve the first portion of the encoding of the message;
retrieving the message by multiplying the first portion of the encoding and the second portion of the encoding by the inverse of the generator matrix; and
displaying the message to the individual.
