Abstract

Method and system for detecting authenticate products based upon alteration of emission characteristics due to interaction of the emissions with the product and the container.

Claims

1. A method for determining the authenticity of, or tracking, a liquid product housed in a translucent container having a label attached thereto having a plurality of light emitting materials on the side attached to said translucent container, said method comprising:

(a) exciting one or more of said light emitting materials through said translucent container and said liquid product;

(b) monitoring one or more of the emitted wavelengths of light generated in response to the excitation;

(c) comparing the emission profile obtained against a standard fingerprint characteristic of an authentic product housed in an authentic container.

2. The method of claim 1 wherein a plurality of emitted wavelengths are monitored.

3. A method for determining whether a liquid product in a translucent package is authentic, said translucent package having a label attached thereto having two or more light emitting materials on the side attached to said translucent package, said method comprising:

(a) exciting two or more of said light emitting materials through said translucent package and through said product;

(b) monitoring two or more of the emitted wavelengths of light generated in response to the excitation;

(c) comparing the emission profile obtained against a standard fingerprint characteristic of an authentic liquid product.

4. The method of claim 3 wherein three or more emitted wavelengths are monitored.
