Abstract
A method of identifying a source of a substance incorporating one or more luminescent markers comprises illuminating the substance to stimulate emission from at least one of the luminescent markers. A luminescent signature is generated from the detected luminescent emission. The source of the substance is identified based on a match between the generated luminescent signature and a pre-defined luminescent signature.
