Abstract
A method and system are provided. The method involves generating a plurality of nanoparticles, isolating fluorescent nanoparticles, embedding the fluorescent nanoparticles in a resin and applying the resin on a product. The system is for product authentication and includes a light source, fluorescence nanoparticles, a detector and a resin for applying on a product. Furthermore, a non-transitory computer readable medium encoded with codes is provided to direct the system to carry out the method.

A method of product authentication, the method comprising the steps of:
- generating an authentication mark on a product, wherein the authentication mark comprises a visible target mark and a pattern formed by a plurality of fluorescent nanoparticles having a peak fluorescence wavelength;
- providing a light source having a peak emission wavelength associated with the peak fluorescence wavelength;
- capturing at least one image of the authentication mark while activating the light source;
- locating the visible target mark in a specific region and extracting the pattern;
- and
- authenticating the product by using the pattern.
A system for product authentication, the system comprising:
- an imaging device capturing images of an authentication mark applied to a product;
- a light source device attached to the imaging device, the light source device comprising at least one light source each having a peak emission wavelength;
- the authentication mark comprises a visible target mark and a pattern formed by fluorescent nanoparticles having a peak fluorescence wavelength associated with one of the peak emission wavelengths;
- a resin into which the fluorescent nanoparticles are embedded, the resin for applying on the product;
- the imaging device capturing images of the authentication mark with the at least one light source being activated;
- locating the visible target mark in a specific region and extracting the pattern to authenticate the product.
A non-transitory computer readable medium encoded with codes, the codes for directing a processor to:
- receive an image data from a detector configured to detect a visible target mark;
- activate a light source having a peak emission wavelength;
- receive the image data from the detector configure to detect a fluorescence response to the light source by fluorescent nanoparticles, wherein the fluorescence response has a peak fluorescence wavelength associated with the peak emission wavelength;
- apply a saturation mask to the image data;
- locate the visible target mark in the image data;
- extracting an authentication pattern;
- and
- perform colorimetric analysis to determine the peak fluorescence wavelength in the authentication pattern to authenticate a product.
