Abstract

A security marker for an item is disclosed which may include (i) an (optional) first component of the marker which is an indicator (e.g., identify the presence of the forensic component marker); (ii) a second component of the marker which is a forensic component defining a unique identification code or other information for the item, e.g., based on a combination of characteristics; and (iii) a chemical scent/trace, e.g., detectable only by a trained dog. Thus, the marker when deployed may advantageously be tracked/located, e.g., by a dog to aid in the tracing of items or personnel following an offence. Advantageously the chemical scent/trace may be detectible at a distance from the item.

Claims

1. A marker system for identifying/tracing items or personnel said marker comprising;

a forensic marker containing a unique code specific for the items/or their location

an indicator material to identify the presence of the forensic marker

a chemical scent detectable only by a trained dog

wherein the marker when deployed can be tracked by the dog to aid in the tracing of items or personnel following an offence.

2. The marker system of claim 1 wherein the chemical scent is substantially odourless to human individuals, non-toxic and substantially colourless under visible light.

3. A marker system of claim 1 wherein the indicator material comprises a fluorescent or phosphorescent material that is capable of fluorescing at particular wavelengths when subjected to a particular stimulus.

4. The marker as in claim 1 which is automatically deployed during the course of an offence.
