<p>A method of generating a marker system for applying to surfaces of items, articles, goods, vehicles, fabrics and/or premises, the method comprising: applying on said surface one or more layers of coding; wherein each layer of coding is applied in a predefined spatially separated pattern, such that each layer of coding provides a unique pattern when subjected to a particular type of stimulus. A marker generated by the method. Also disclosed is a method of identifying a marker system applied to surfaces of items, articles, goods, vehicles, fabrics and/or premises, wherein the marker system comprises one or more layers of coding, the method comprising: using a digital camera to measure each layer of coding under UV and/or IR radiation; recording the measurements defining the predefined spatially separated pattern from the surface; and comparing the recorded measurements defining the predefined spatially separated pattern with a database comprising details of all measurements.</p> |
