System and method for tamper detection using RFID devices
First Claim
1. A system for status indication, comprising:
- a security device, having a first portion disposable on a first side of a separation boundary of a separable object, a second portion disposable on a second side of the separation boundary, and a separation region between the first portion and the second portion, the security device further having a first radio frequency identification (RFID) circuit configured to provide a first return signal and a second RFID circuit configured to provide a second return signal, wherein the first RFID circuit includes a first processor disposed entirely on the first portion and a first antenna spanning the separation region, and wherein the second RFID circuit includes a second processor disposed entirely on the second portion and a second antenna disposed entirely on the second portion; and
a data device, comprising a microprocessor and system memory, an RFID reader and a radio antenna, configured to send and receive radio frequency signals with the first RFID circuit and the second RFID circuit, and configured to provide a graphical indication to a user of a secured status in response to receiving the first return signal with the second return signal, provide a graphical indication to a user of a compromised status in response to receiving the second return signal without the first return signal, and provide a graphical indication to a user of a no signal status in response to receiving neither the first return signal nor the second return signal.

Abstract
A system for tamper detection includes a security device and a data device. The security device has a first portion disposable on a first side of a separation boundary of a separable object, and a second portion disposable on a second side of the separation boundary. The security device further includes a first Radio Frequency Identification (RFID) circuit configured to provide a first return signal. The data device includes a microprocessor and system memory, an RFID reader and a radio antenna. The data device is configured to send and receive radio frequency signals with the first RFID circuit, and to recognize the first return signal as indicating an untampered condition of the separable object.

13. A radio frequency identification (RFID) device, comprising:
-
a first portion and a second portion, coupled at a separation region that is configured to be disposed across a separation boundary of a separable object; a first RFID circuit, configured to transmit a first signal to an RFID reader, having a first processor disposed entirely on the first portion and a first antenna extending across the separation region separation of the first processor and first antenna preventing transmission of the first signal; and a second RFID circuit, configured to transmit a second signal to the RFID reader, having a second processor disposed entirely on the second portion and a second antenna disposed entirely on the second portion; wherein transmission of the first signal with the second signal causes the RFID reader to display a graphical indication of a secured status, wherein transmission of the second signal without the first signal causes the RFID reader to display a graphical indication of a tampered status, and wherein transmission of neither the first signal nor the second signal causes the RFID reader to display a graphical indication of a no signal status. - View Dependent Claims (14, 15, 16)

17. A method for facilitating inspection of a plurality of sealed objects, comprising:
-
placing a first processor of a first Radio Frequency Identification (RFID) device on a first side of a separation boundary; placing a first antenna of the first RIFD device across a separation boundary of a sealed object; placing a second processor of a second RFID device on a second side of the separation boundary; placing a second antenna of the second RFID device entirely on the second side of the separation boundary; configuring a data device to scan and receive a return signal from the first RFID device and from the second RFID device that indicates a tampered condition of the sealed object; and providing, via the data device, an output via a graphical user interface that associates the tampered condition with one of three statuses, the three statuses including a secured indication, a no signal indication, and a compromised indication. - View Dependent Claims (18, 19, 20)
