1. A system for authenticating one or more instantiations of a product comprising:
- a secure server with a database storing a subset of unique code strings, wherein each unique code string of the subset is marked on a unique instantiation of a product, wherein the subset of unique code strings is derived from a code string model having finite parameters of code string length and code string character types, the finite parameters defining the total quantity of unique code strings, a size B of a subset of unique code strings of a total quantity of unique code strings is selected based on the equation B=P*(ND), where P is a probability of guessing a code string of a subset of unique code strings, N is a quantity of the finite parameters of a code string length, D is a quantity of code string character types, and ND is the total quantity of unique code strings; and
a communication device, coupled to the secure server by a network, that transmits an inquiry signal to the secure server, wherein the inquiry signal includes a code string marked on an instantiations of the product,wherein the secure server receives the inquiry signal, searches the database to determine whether the code string in the received inquiry signal matches a code string of the subset of unique code strings stored in the database in order to validate authenticity of the instantiation of the product corresponding to the code string in the received inquiry signal.

Abstract
A subset of unique codes are generated from a set of codes. The subset of codes are stored in a database on a secure server and each of the codes is marked on a corresponding instantiation of the product. The marked instantiations are distributed. During their distribution, the marked instantiations are verified for authenticity and for routing. This verification is performed by reading or scanning the codes on the instantiations, and transmitting that information to the secure server for comparison against the codes and other information located in the database contained therein.
