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.

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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. An identifier comparing:
-
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. - View Dependent Claims (21, 22, 23)
