Patent ID: 8712873

Claim:
A method of remotely auditing inventoried assets, comprising: configuring auditing information for each asset as a random distribution of non-clonable elements by creating an auditing label for each asset with the non-clonable elements configured as a random distribution of three-dimensional light-modifying elements thereon as the auditing information; associating the auditing information with each asset by applying the auditing label on each asset; associating identification information with each asset by creating an identification label for each asset with the identification information thereon, and by applying the identification label on each asset; capturing the auditing information and the identification information from the auditing label and the identification label associated with each asset with an interrogation device at an inventory location; identifying each asset from the captured identification information at the inventory location; determining from the captured auditing information whether each identified asset is present or absent at the inventory location by verifying that the light-modifying elements on the auditing label are indeed three-dimensional; and sending to auditor inventory information about the assets based on the captured auditing information and the captured identification information.
