Abstract

An authentication method includes determining that a unique overt identifier is associated with a product; detecting that a random covert identifier is associated with the product, wherein the covert identifier includes at least one taggant particle, the unique overt identifier is combined with the random covert identifier, and the unique overt identifier is not a function of the random covert identifier; and comparing the unique overt identifier and the random covert identifier respectively to a unique overt number and a random covert number stored in a database.

Claims

1. An authentication method comprising:

determining that a unique overt identifier is associated with a product; and

detecting that a random covert identifier is associated with the product, wherein the covert identifier includes at least one taggant particle, wherein the unique overt identifier is combined with the random covert identifier, and the unique overt identifier is not a function of the random covert identifier; and

comparing the unique overt identifier and the random covert identifier respectively to a unique overt number and a random covert number stored in a database.

2. The authentication method of claim 1 wherein detecting a covert identifier includes:

locating an area where a covert identifier is to be located; and

determining the presence of the covert identifier.

3. The authentication method of claim 2 wherein determining the presence of the covert identifier includes determining the presence of a plurality of taggant particles.

4. The authentication method of claim 2 wherein determining the presence of the covert identifier includes reading the covert identifier.

5. A method of product identification comprising:

placing a random covert identifier on a product that includes material for determining a random number; and

placing a unique overt identifier on the product, wherein the unique overt identifier is not a function of the random covert identifier, and wherein the unique overt identifier and the random covert identifier associated with the product are respectively used to compare to a unique overt number and a random covert number stored in a database to authenticate the product.

6. The product identification method of claim 5 further comprising relating the covert identifier and the overt identifier to the product.

7. The product identification method of claim 6 wherein relating the covert identifier and the overt identifier to the product further comprises associating the covert identifier and the overt identifier in a data base.

8. The product identification method of claim 6 further comprising relating other product information with the product.

9. The product identification method of claim 6 further comprising relating product manufacturing information to the product.

10. The product identification method of claim 5 wherein placing a covert identifier on a product, and placing an overt identifier on the product includes labeling a product with a label that includes a covert identifier and an overt identifier.

11. The product identification method of claim 10 wherein the covert identifier is on a portion of the label.

12. An authentication system comprising:

a sensor for detecting a random covert identifier associated with a product;

a sensor for determining a unique overt identifier associated with the product, wherein the unique overt identifier is not a function of the random covert identifier; and

a comparator for comparing the unique overt identifier and the random covert identifier associated with the product respectively to a unique overt number and a random covert number stored in a database.

13. The authentication system of claim 12 further comprising a locator for locating the covert identifier associated with the product.

14. The authentication system of claim 13 wherein the locator includes a datum associated with the product.

15. The authentication system of claim 12 further comprising means to reject authentication of the product when the covert identifier is not found in a selected position on the product.

16. The authentication system of claim 12 wherein the sensor for detecting a covert identifier associated with the product which operates outside the spectrum of visual light.

17. The authentication system of claim 12 further comprising a memory module for storing a value associated with a covert identifier and for storing a value associated with an overt identifier.

18. The authentication system of claim 17 further comprising a comparator for comparing a detected value associated with a covert identifier of a product with a previously stored value for the covert identifier previously associated with the product.

19. The authentication system of claim 17 further comprising a comparator for comparing a detected value associated with a covert identifier associated with the product and a detected value of the overt identifier associated with the product, to a previously stored covert identifier associated with the product and previously stored overt identifier associated with the product.

20. An identifier comprising:

a random covert identifier portion; and

a unique overt identifier portion, the covert identifier portion including particles, wherein the unique overt identifier is not a function of the random covert identifier,

wherein the unique overt identifier portion and the random covert identifier portion are respectively used to compare to a unique overt number and a random covert number stored in a database to authenticate a product with the identifier.

21. The identifier of claim 20 wherein the identifier includes at least one marking on a product.

22. The identifier of claim 20 wherein the identifier includes a label.

23. The identifier of claim 20 wherein the identifier includes a datum for locating a repeatable read portion of covert identification portion.
