System, method and device to detect product tampering
First Claim
1. A system to detect product tampering comprising:
- one or more objects;
two or more electronic components, wherein at least one electronic component is irremovably attached to each of the one or more objects;
an electronically readable encryption recorded on each of the two or more electronic components;
at least one destructible conducting path electrically attached to each of the two or more electronic components and fixedly attached to the substrate of its respective electronic component, whereby the destructible conducting path is disrupted when the substrate is tampered, thereby modifying the function of the electronic components;
a means for permanently attaching the one or more objects to at least one surface, wherein any attempt to manipulate the at least one surface shall disrupt the destructible electrically conducting path;
a means for electronically reading and sorting the electronically readable encryption on each of the two or more electronic components.

Abstract
Embodiments of the present invention disclose an efficient and inexpensive method for detecting tampered products utilizing current off the shelf components. Features of some embodiments provide for a RFID labeling system that uses multiple RFID components attached to a single product unit being embedded in the product'"'"'s label and one or more tamper labels. Such RFID labels usually comprise an adhesive label containing an RFID component, a destructible conducting path that acts as an antenna and a unique encryption. The RFID labels transmit the encryption when irradiated by an RF scanner. A complete inventory of multiple associated encryptions reported during an RFID scan of a product package provide positive indication that product has not been tampered with. A missing encryption indicates a faulty product seal or an event of tampering.

8. A tamper prevention device comprising:
-
at least one sheet comprising;
a product label portion; and
one or more tamper strip portions;
at least one RFID component, wherein the at least one RFID component is fixedly attached to each of the product label portion and the one or more tamper strip portions;
an electronically readable encryption recorded in each of the at least one RFID components wherein the electronically readable encryptions are associated with each other;
at least one destructible conducting path electrically attached to each of the at least one RFID components and fixedly attached to the portion of its respective RFID component, wherein the at least one destructible conducting path is at least partially routed through the at least one tamper strip portion; and
a means for permanently attaching the at least one sheet to at least one surface, wherein any attempt to manipulate the at least one surface shall disrupt the at least one destructible electrically conducting path fixedly attached to a portion. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method to detect product tampering comprising:
-
irremovably fixing a first RFID label to a surface of a product package, wherein the first RFID label integrally comprises a first electronically readable encryption recorded on a first RFID component connected to a first destructible conducting path;
irremovably affixing one or more additional RFID labels to one or more accesses in the product package, wherein manipulating any of the one or more accesses shall disrupt one of an additional RFID component and an additional destructible conducting path electrically connected to the additional RFID component each of which are integrally attached to the one or more additional RFID labels, wherein further the additional RFID component contains an additional electronically readable encryption that is associated with the first electronically readable encryption;
reading the first electronically readable encryption and the additional electronically readable encryptions;
storing the first electronically readable encryption and the additional electronically readable encryptions;
determining that an additional electronically readable encryption associated with first electronically readable encryption failed to be detected in the reading step; and
generating an error. - View Dependent Claims (16, 17, 18, 19, 20)
