1. A method for detecting unauthorized duplication of software applications in at least one processing device that includes a radio link, the method comprises the steps of: a) when a first processing device is communicating with a communication system via the radio link, detecting, by a monitoring computer, a unique identity of the first processing device and a software application code; b) when a second processing device is communicating with the communication system via the radio link, detecting, by the monitoring computer, a unique identity of the second processing device and a software application code; c) when the unique identity and the software application code of the first processing device and the second processing device are detected, comparing, by the monitoring computer, the software application code of the first processing device with the software application code of the second processing device; and d) when the software application code of the first processing device matches the software application code of the second processing device, identifying, by the monitoring computer, that the first processing device and the second processing device have unauthorized duplication of at least one software application.
