Abstract:
1. A method for authenticating a physical object in a process control operation, the method comprising; directing the physical object into a read zone; retrieving information stored on a memory of an RFID tag attached to said physical object; capturing a physimetric property of said physical object; separating said retrieved information to obtain a stored Unique ID and a stored coded physimetric property, the coded physimetric property is encoded with a Secured Hash Algorithm; decoding said stored coded physimetric property to obtain a decoded physimetric property; comparing captured physimetric property to said decoded physimetric property; sending the results of said comparison to a controlling device; if said captured physimetric property is equal, within a percentage deviation, to said decoded physimetric property, then passing said physical object through said read zone.
