Abstract

A method for authenticating a product where the product is composed of a plurality of components is described. The method for authenticating the product comprises providing a liquid compound, e.g. paint, that comprises at least one invisible market, e.g. nucleic acid, in which the compound is associated with a first entity. The method then proceeds to apply the compound to the surface of the product at the juncture of at least two components. The method also comprises associating the application of the compound to the at least two components with the first entity.

Claims

1. A method for authenticating a product wherein said product is composed of a plurality of components, said method for authenticating the product comprising:

providing a liquid compound comprising at least one invisible marker, said compound associated with a first entity;

applying said compound to the surface of said product at the juncture of at least two components; and

associating said application of said compound to the at least two components with said first entity.

2. The method of claim 1 further comprising transferring said product to a second entity.

3. The method of claim 2 further comprising inspecting the compound and authenticating that the product is associated with the first entity by detecting said invisible marker.

4. The method of claim 1 wherein said product is integrated into a manufactured product.

5. The method of claim 1 wherein said invisible marker comprises a nucleic acid.

6. The method of claim 1 wherein said invisible marker comprises a UV ink.

7. The method of claim 1 wherein said compound is a paint.

8. A method for authenticating a product wherein said product is composed of a plurality of components, said method for authenticating the product comprising:

providing a paint comprising at least one nucleic acid marker, said compound associated with a first entity;

applying said paint to the surface of said product at the juncture of at least two components; and

associating said application of said paint with said first entity.

9. The method of claim 8 further comprising:

collecting a sample of the paint; and

analyzing the sample for the nucleic acid marker.

10. The method of claim 9 further comprising authenticating that the product is associated with the first entity by detecting the nucleic acid marker.

11. The method of claim 9 wherein the sample is analyzed using PCR.

12. The method of claim 9 further comprising transferring said product along a supply chain.

13. A method for authenticating a particular product, comprising:

providing a marker compound having at least one nucleic acid product applying the marker compound to at least one particular product, which enters at least one supply chain;

collecting a sample of said marker compound from said particular product after said particular product has entered said supply chain; and

,

identifying said nucleic acid product in said particular product.

14. The method of claim 13 wherein the particular product comprises at least two parts.

15. The method of claim 14 wherein the marker compound is applied as a torque stripe.

16. The method of claim 15 wherein the nucleic acid product is identified using PCR.

17. The method of claim 14 wherein the particular product is a fastener.
