Abstract
The present invention provides a method for identifying components based upon selected physical characteristics. Initially, a characterization function that will produce a unique characterization value within a set of components, is (or has been) assigned to the set of components. The characterization function is a function of at least one physical characteristic that is shared by the components within the set of components. Next, the measurable physical characteristics defined as part of the characterization function are measured by testing. A characterization value, which is calculated from the assigned characterization function, is determined for each component. Each component that is to be subsequently identified is then identified by its associated characterization value.
