1. A method for identifying a data recorder having a first operational configuration of at least one of hardware components and software components, comprising:receiving, by a processing device, configuration information for changing the first operational configuration of the data recorder to a second operational configuration that is defined by a plurality of data recording input parameters and a configuration for each said data recording input parameters which is to be employed during use of the data recorder in a particular data recording application;
transforming, by the processing device, the configuration information in accordance with a pre-defined encoding scheme;
using a signature generating algorithm to generate with said processing device a unique signature for said data recorder, the unique signature comprising a code which uniquely identifies the data recorder based on the configuration information which was previously transformed, wherein the configuration information is recoverable from the unique signature;
storing, on a memory of said data recorder, the unique signature; and
responsive to an input request, providing at least the unique signature to a user to facilitate unique identification of the data recorder and the configuration information.
