Abstract

Apparatus, system, and method to authenticate and identify objects using nanoparticles are described herein. In one embodiment, a computer-readable storage medium includes executable code to: (1) derive an index based on an authentication image of a marking; (2) select a reference image of the marking based on the index; (3) compare the authentication image with the reference image to determine whether the authentication image matches the reference image; and (4) produce an indication of authenticity based on whether the authentication image matches the reference image.

Description

[0001] (cross-reference to related application) [0002] This application claims priority to US Provisional Application No. 60 / 716656, filed September 12, 2005, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to nanoparticles. More specifically, the present invention relates to the use of nanoparticles to identify and identify objects. Background technique [0004] Objects to be authenticated or identified are sometimes provided with specific markings, which may be part of the object itself or may be coupled to the object. For example, a commonly used indicium is a barcode comprising a linear array of elements printed directly onto the object or onto a label coupled to the object. These elements typically contain bars and spaces, where bars of different widths represent strings of binary ones and spaces of different widths represent strings of binary zeros. While barcodes are us...
