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.
Claims23
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.
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.
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.
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.
