Description

[Anchor Lead]Some 450 billion dollars in fake products are distributed worldwide and Korean researchers have developed a technology to set apart forged goods from the genuine with just a breath. Find out how it works in this report. [Pkg]When a person blows a breath onto this transparent glass plate, a four-leaf clover emerges. When the breath has evaporated, the shape also disappears. The plate is a transparent film consisting of nanometer thick layers of a special chemical substance which reacts to moisture. A team led by Dr. Park Jong-mok at the Korea Research Institute of Chemical Technology has developed the film. The team applied the theory that when polymeric materials with different light refraction indices are arranged in one direction, they only reflect light under certain stimuli. The institute says that by using the transparent film, illegal circulation of counterfeit liquor, tobacco and cosmetics can be easily prevented. The institute stresses that compared to existing security technologies, the film can be produced at an affordable cost and it's completely impossible to copy or reproduce the film.[Soundbite] Park Jong-mok(PhD, Korea Research Institute of Chemical Technology) : "The cost of materials is cheap. Even the production process, compared to existing ones, is incredibly simple. The film can also be made consecutively so it's very economical overall."Last month, the Korea Institute of Machinery & Materials also developed an encryption technology using ultra fine laser beams. State of the art technological research focused on rooting out counterfeit goods is increasingly drawing attention.
