Abstract
Disclosed is a method of appraising a genuine product using a quantum dot which includes obtaining image data for fluorescence generated from a target product and a quantum dot layer located in one region of the target product by laser light; determining a relative height and a relative distance between target quantum dots constituting the quantum dot layer by using the image data for the fluorescence, and generating a quantum dot arrangement map; and determining whether the target product is genuine by comparing the quantum dot arrangement map with a previously stored reference quantum dot arrangement map.
