Abstract
A monitoring computer monitors the communications occurring within at least one communication system for at least one unique processing device identification code associated with a processing device. Upon detecting the at least one device identification code, the monitoring computer compares the type of application in use by the processing device with known software parameters (including the allowable types of applications and their serial numbers) for the processing device. When the type of application in use by the processing device does not substantially match the known software parameters for the processing device, the processing device is identified as using an unauthorized and/or duplicated software application.
