SECURITY SYSTEM AND METHOD OF MARKING AN INVENTORY ITEM AND/OR PERSON IN THE VICINITY

摘要

A method of marking an inventory item includes providing an activatable smoke generator and a reservoir for holding a smoke fluid and adapted to provide a flow of smoke fluid to the generator. The reservoir contains a smoke fluid including a carrier nucleic acid having a uniquely identifiable sequence, and upon activation of the smoke generator, marker smoke is generated and targeted to flow over the inventory item. The method further includes activating the smoke generator to produce the marker smoke including the carrier nucleic acid so as to cause the marker smoke to flow over the inventory item and thereby to detectably mark the inventory item with carrier nucleic acid.
