Abstract

Example embodiments of systems and methods for preventing chip fraud are provided. A chip fraud prevention system may comprise a device including a chip, wherein the chip is at least partially encompassed in a chip pocket. One or more connections may be communicatively coupled to one or more surfaces of the chip, and a capacitance member may be coupled to a surface of the chip. The capacitance member may comprise a known capacitance value and the chip may comprise a memory containing an applet, wherein the applet is configured to measure the capacitance value of the capacitance member.

First claim

What is claimed is:

1. A method of preventing chip fraud, the method comprising the steps of:
positioning a chip at least partially within a substrate, the chip comprising a memory storing an applet;
coupling a capacitance member to a surface of the chip, wherein the capacitance member comprises a capacitance value;
detecting, by the applet, the capacitance value of the capacitance member; and
issuing, by the applet, a fraud alert upon detecting a change in the capacitance value greater than a predetermined amount, wherein
the substrate comprises a chip pocket,
the chip is disposed in the chip pocket,
the capacitance member is positioned in the chip pocket and beneath the chip,
the chip pocket comprises one or more peaks and one or more valleys,
the capacitance member is coupled to the surface of the chip through one or more connections, and
the one or more connections are disposed within adhesives that completely or partially fill air gaps between the one or more peaks and one or more valleys.

2. The method of claim 1 , further comprising:
detecting, by the applet, an initial capacitance value of the capacitance member; and
periodically detecting, by the applet, the capacitance value of the capacitance member.

3. The method of claim 2 , further comprising comparing, by the applet, a detected capacitance value of the capacitance member to the initial capacitance value to measure a change in the capacitance value.

4. The method of claim 1 , wherein the capacitance member comprises a first end in data communication with the chip.

5. The method of claim 4 , wherein the first end is configured to apply a force to the surface of the chip.

6. The method of claim 1 , wherein:
the chip is positioned at least partially within the chip pocket, and
the surface of the chip to which the capacitance member is coupled is within the chip pocket.

7. The method of claim 6 , wherein:
the capacitance member is positioned between at least one selected from the group of the one or more peaks and the one or more valleys.

8. The method of claim 7 , wherein the one or more peaks and one or more valleys comprise a saw tooth milling pattern.

9. A device, comprising:
a chip comprising a memory storing an applet; and
a capacitance member coupled to a surface of the chip, the capacitance member comprises a capacitance value,
wherein the applet is configured to detect the capacitance value,
wherein the applet is configured to issue a fraud alert upon detecting a change in the capacitance value greater than a predetermined amount, and
wherein
the substrate comprises a chip pocket,
the chip is disposed in the chip pocket,
the capacitance member is positioned in the chip pocket and beneath the chip,
the chip pocket comprises one or more peaks and one or more valleys,
the capacitance member is coupled to the surface of the chip through one or more connections, and
the one or more connections are disposed within adhesives that completely or partially fill air gaps between the one or more peaks and one or more valleys.

10. The device of claim 9 , wherein the device comprises a vehicle.

11. The device of claim 9 , wherein the device comprises an appliance.

12. The device of claim 9 , wherein the device comprises at least one selected from the group of a card, a computing device, a mobile device, and a wearable device.

13. A card, comprising:
a chip comprising a memory storing an applet; and
a capacitance member coupled to a surface of the chip, the capacitance member comprises a capacitance value,
wherein the applet is configured to detect the capacitance value,
wherein the applet is configured to issue a fraud alert upon detecting a change in the capacitance value greater than a predetermined amount, and
wherein
the substrate comprises a chip pocket,
the chip is disposed in the chip pocket,
the capacitance member is positioned in the chip pocket and beneath the chip,
the chip pocket comprises one or more peaks and one or more valleys,
the capacitance member is coupled to the surface of the chip through one or more connections, and
the one or more connections are disposed within adhesives that completely or partially fill air gaps between the one or more peaks and one or more valleys.

14. The card of claim 13 , wherein the applet is further configured to:
detect an initial capacitance value of the capacitance member,
periodically detect the capacitance value of the capacitance member, and
compare a detected capacitance value of the capacitance member to the initial capacitance value to measure a change in the capacitance value.

15. The card of claim 13 , wherein the capacitance member comprises at least one selected from the group of a wire, a spring, and a coil.

16. The card of claim 13 , wherein the capacitance member comprises at least one selected from the group of a particle and a flake.
