Abstract
A method and system for facilitating the identification and/or authentication of objects, and to a method and system for the marking of objects with an identity and/or as of authentic origin, and a set of objects marked to facilitate subsequent identification and/or authentication are described. The marking comprises incorporating into an object or part thereof or onto a tag mechanically engaged therewith a marker material exhibiting a characteristic radiation interaction response to incident high-energy ionizing radiation from a test source that is known to vary spectroscopically across the spectrum of the source. The presence or otherwise of the marker material may be determined by subsequent interrogation of an object with a suitable radiation source and detector to infer whether an object is of marked identity or origin.
