Abstract
An authentication method includes reading a covert identifier associated with a product, reading an overt identifier associated with the product, and matching a covert identifier with an overt identifier to authenticate the product.
Claims19
An authentication method comprising:
- reading a random covert identifier associated with a product;
- reading a unique overt identifier associated with the product;
- and
- combining the random covert identifier with the unique overt identifier to authenticate the product to form a pair of identifiers;
- 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, wherein the unique overt identifier is not a function of the random covert identifier.

A machine-readable medium that provides instructions that, when executed by a machine, cause the machine to perform operations comprising:
- reading a random covert identifier associated with a product;
- reading a unique overt identifier associated with the product;
- and
- combining the random covert identifier with the unique overt identifier to authenticate the product to form a pair of identifiers;
- 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, wherein the unique overt identifier is not a function of the random covert identifier.
3 more elements
A system comprising:
- a memory unit to store instructions;
- and
- a processor to receive instructions from the memory unit, the instructions causing the processor to perform operations comprising:
- reading a random covert identifier associated with a product;
- reading a unique overt identifier associated with the product;
- and
- combining the random covert identifier with the unique overt identifier to authenticate the product to form a pair of identifiers;
- 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, wherein the unique overt identifier is not a function of the random covert identifier.
