Abstract

There is provided a marker system for applying to surfaces operating at high temperatures, the marker system comprising a marker and a temperature resilient medium capable of securing the marker system onto a high temperature surface; wherein the medium contains an inorganic matrix to secure the marker to a surface; wherein the marker comprises a fingerprint to render the marker unique; and wherein the marker system further comprises indicator material to indicate the presence of the marker. Further provided is a composition comprising the marker system. Further provided are engines, exhaust systems and/or catalytic converters or other surfaces operating at high temperatures comprising a surface impregnated with the marker system.

Abstract

There is disclosed by the present invention a method of generating a marker to distinguish between genuine and counterfeit goods by applying to surfaces of items, articles, goods, vehicles, fabrics and/or premises, the method comprising: applying at least one coding to the surface, wherein the coding is applied randomly such that the coding provides a unique pattern when subjected to a particular type of stimulus.

Abstract

A marker system for applying to surfaces of items, articles, goods, vehicles and/or premises, said marker system comprising: a marker comprising a temperature resilient medium having a predefined carbonisation temperature capable of securing the marker system onto a surface; wherein the medium contains an inorganic matrix having a predefined fusing point lower than the predefined carbonisation temperature of the medium; such that when the marker system is subjected to temperatures above the predefined carbonisation temperature of the medium, the inorganic matrix fuses to the marker to form an adhesive protective layer thereby securing the marker onto said surface. A composition comprising the marker system. An item, an article, a good, a vehicle and/or premises comprising a surface impregnated with the marker system.

Abstract

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.
