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 carbonization 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 carbonization temperature of the medium; such that when the marker system is subjected to temperatures above the predefined carbonization 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: The present invention relates to the use of unique markers in the identification and tracking of objects. The present invention provides large numbers of unique markings for application to items as part of a marking system. The present invention provides a new approach to laboratory analysis and a means of rapid in-field identification of goods using a hand-held scanner. It provides data that can be used as a means of product tracking, identification of counterfeit product and to prove ownership of stolen goods.

Abstract: The present invention relates to the use of marker systems for the security and tracing of items, articles, goods, vehicles or persons. The present invention provides a marker for applying to the surfaces of items, the marker comprising at least one fluorescent material capable of fluorescing at a specific wavelength when subjected to stimulus. The marker can also include at least one material which is phosphorescent and emitting at a specific wavelength. In use, the measured fluorescence and phosphorescent response obtained from the marker are visually compared to examples of the desired colour output for the case in hand to verify the authenticity of the item.

Abstract: A medium is provided in which nano-crystalline semiconductors or quantum dots are stable for extended periods when subjected to exterior lighting. The colour emission of the resultant quantum dots provides a fingerprint which is still effective after one year of exposure to exterior conditions. Such encapsulation protects the quantum dots in exterior conditions, so that they may be used as pigments or coding systems based on their optical emission.
