taggant
A taggant can mean a radio frequency microchip used in automated identification and data capture (see RFID). In such cases, electronic devices use radio waves to track and identify items, such as pharmaceutical products, by assigning individual serial numbers to the containers holding each product. This technology may prevent the diversion or counterfeiting of drugs by allowing wholesalers and pharmacists to determine the identity and dosage of individual products. A taggant is also a chemical or physical marker added to materials to allow various forms of testing. It is believed that physical marker taggants generally consist of microscopic particles built up in many layers, which are made of different materials. It is a somewhat secretive process, but products that may be affected include ink, paper, perfume, and medication. Taggants allow testing marked items for qualities such as lot number and concentration (to test for dilution, for example). In particular, taggants are known to be widely used in plastic, ink, sheet and flexible explosives. A software taggant is a cryptographic signature added to software that enables positive origin identification and integrity of programs. Software taggants are using standard PKI techniques (see Public key infrastructure) and were introduced by the Industry Connections Security Group of IEEE in an attempt to control proliferation of malware obfuscated via executable compression. ==Explosive taggants==
There are two types of taggant which have been considered for use with explosives. One is to help detect the presence of a bomb in, for example, airport screening of luggage; and the other to assist the police in identifying the explosive after the detonation of such a bomb.
