1. A communication system comprising:

  • a set of communication devices comprising at least a first and a second communication device, the first communication device having a wide area interface, the second communication device having a radio frequency receiver, each of the first and the second communication devices having a local interface that can communicate in a distance substantially shorter than that of the wide area interface;

    one of the first and the second communication devices generating a non-deterministic digital content and delivering using the local interfaces of the first and the second communication devices the non-deterministic digital content to another of the first and the second communication devices;

    a remote site located remotely from the first and the second communication devices, the remote site having a wide area interface that can receive the non-deterministic digital content and a first set of digital data from the wide area interface of the first communication device, subsequently the remote site transmitting radio frequency signal encoded with a second set of digital data, the second set of digital data comprising at least the non-deterministic digital content and the first set of digital data; and

    the second communication device receiving the radio frequency signal using the radio frequency receiver and recovering the first set of digital data and non-deterministic digital content, the second communication device using the non-deterministic digital content to verify that the first set of digital data is sent by the first communication device.
