Definitions
- Tamper detection devices and other event detection devices frequently • depend on visual inspection of a mechanism that permanently changes its mechanical properties in response to a particular event.
- tamper detection for a medicine bottle may be indicated with a paper seal that is attached to both the bottle and the bottle cap, such that opening the cap tears the paper. If visual inspection shows that the seal is torn, that indicates that the cap has been removed and the contents of the bottle possibly tampered with. If the seal is intact, it is assumed that the bottle has not been opened. While such indicators are inexpensive and generally reliable, detection depends on a human being visually looking at the seal. Such techniques are not efficient for inspecting large numbers of containers, or for inspecting containers that are not easily viewed, such as the contents of a shipping bay in a commercial freight vehicle.

- RFID tag comprises an RFID tag circuit to provide data storage and signal processing within the RFID tag, and an RFID antenna to receive and transmit signals to/from the RFID tag.
- RFID RFID
- the definition of 'transmission' from an RFID tag may include the modulated reflection of a wireless signal received by the associated RFID antenna.
- Some embodiments of the invention include an RFID tag whose response includes the status of a security sensing element.
- the security sensing element may indicate the status of a security device whose characteristics are changed by the occurrence of a particular physical event, such as opening a container. In some of those embodiments, that event may change the electrical coupling between the sensing element and the RFID tag, such as by breaking the continuity of an electrical element in a manner that is essentially irreversible, or by changing a multi-bit readout between the sensing element and the RFID tag.
- Fig. 1 shows a block diagram of an RFID tag and security sensor, according to an embodiment of the invention.
- the RFID tag comprises RFID tag circuit 190 and RFID antenna 195.
- Security sensor device 180 is also shown coupled to RFID tag circuit 190 through a breakable continuity loop 185.
- the security sensor device 180 may be constructed such that when mounted on an openable container, the security sensor device 180 and the continuity loop 185 will both break (e.g., along the indicated dashed lines) if the container is opened.
- the illustrated RFID tag circuit 190 may comprise various components, such as, for example, RF circuitry 191 to receive and transmit radio frequency signals, identification register 193 to contain a code in non- volatile circuitry that identifies the RFID tag, a status circuit 194 to indicate a status of security sensor 180, and a power circuit 192 to provide electrical power to operate the various other components 191, 193, and 194.
- RF circuitry 191 to receive and transmit radio frequency signals
- identification register 193 to contain a code in non- volatile circuitry that identifies the RFID tag
- a status circuit 194 to indicate a status of security sensor 180
- a power circuit 192 to provide electrical power to operate the various other components 191, 193, and 194.
- some of the electrical energy from incoming signals that are received through antenna 195 may be collected in power circuit 192 (e.g., stored in capacitor Cl), until there is sufficient electrical energy to operate the other components of RPID tag circuit 190.
- Security sensor 180 may be physically mounted or otherwise attached to a container with a door, lid, or other opening device, in a manner that causes the continuity loop to break if the container is opened. In the illustrated embodiment, such a break may occur along the dashed lines, causing the continuity loop 185 to physically break in two. This may in turn prevent the voltage from power circuit 192 from reaching the input of status circuit 194.
- Various circuit design techniques may be used to make sure the operational input to status circuit 194 is in one state when the continuity loop 185 is intact, and in another state when continuity loop 185 is broken.
- the illustrated embodiment may provide a logic high signal when continuity is present, and a logic low signal when continuity is absent, but the opposite convention may also be used.
- the state of the input to status circuit 194 may not matter.
- the RFID tag When the RFID tag is prompted to transmit, for example by receiving a radio frequency signal transmitted by RFID reader 199, the RFID tag may transmit the identification code in identification register 193, as well as the status indicated by status circuit 194. In some embodiments this data may be transmitted in a bit-serial fashion, by being shifted through a shift register to the RF circuit 191.
- status circuit 194 may comprise a flip-flop, register, or other circuit element that stores the state as long as power is available to status circuit 194. In other embodiments, status circuit 194 may merely provide the signal level in a non-stored state as an input to be sensed and transmitted only when needed. In some embodiments a single bit may be used to indicate continuity status, while in other embodiments multiple bits may provide that status.
- the status bit(s) may be located at any feasibly point in the data transmitted by the RFID tag.
- the RFID tag may be 'polled' by an RFID reader when the RFID tag is to respond.
- An RFID poll may take any of various forms, such as but not limited to: 1) receipt of any RF energy that will be accumulated in the power circuit 192, 2) receipt of RF energy in the proper frequency band, 3) receipt of a modulated signal that indicates this specific RFID tag is to respond, 4) etc.
- the RFID tag may transmit the contents of identification register 193 and status circuit 194, as well as any other information (not shown) the RFID tag may be designed to transmit.
- the RFID tag may be a 'passive' RFID tag, i.e., it may use the energy from incoming signals to power its own circuits, and its circuits may be non-operational in the absence of such incoming signals.
- the RFID tag may be an 'active' tag, i.e., it may receive operational power from a battery or other internal power source. In either case, when the RFID tag is active, the continuity of loop 185 may be sensed at status circuit 194, and that continuity status may be transmitted along with any other pertinent information the RFID tag may be designed to transmit.
- Figure 2 shows a diagram of a security device on the door(s) of a container, according to an embodiment of the invention.
- security device 220 may be physically attached to one or more doors 250, 260 of a container 270, in a manner that causes the security device 220 to physically break when the door(s) are opened.
- a lock 240 may also be used to enhance security by making unauthorized opening of the doors more difficult.
- a rectangular cabinet with doors is shown, the same principals may be used on any type of container with a movable part that acts to open and/or close the container.
- Such containers may include, but are not limited to, such things as 1) a bottle with a cap, 2) ajar with a lid, 3) a box with a flap, 4) a shipping container with a door, 5) a room with a door, 6) a building with a door, 7) a land area with a gate, 8) etc.
- the security device may be attached to the container after the opening is closed, so that the next time the container is opened, the security device will break and the electrical continuity previously described will be broken.
- the security device 220 may comprise, for example, an RFID tag 210 attached to a base that is adhesively attached to doors 250, 260, such that when one or both doors is opened the security device will break along perforations 225, thus breaking continuity loop 230 at the same time.
- An RFID tag on a paper adhesive label may serve as one such example.
- Figure 3 shows a diagram of a security sensor with a continuity loop, according to an embodiment of the invention.
- the security sensor may include RFID tag 390 on support 370, with an electrically conductive loop 380 providing electrical continuity between two contacts of the RFID tag 390.
- Support 370 may provide mechanical support for RFID tag 390 and the ends of loop 380, as well as a visual indication to show that the security sensor is in place.
- Fig. 3 shows loop 380 passing through the handles 355, 365 that are attached to doors 350, 360, such that opening the doors will break the conductive loop 380, and electrically disconnect the two contacts of RFID tag 390 from each other.
- the conductive loop 380 may have a one-time connection mechanism (not shown) that permits the loop to be passed through the handles and then connected in a manner that is irreversible (e.g., once properly connected, the loop cannot be disconnected without breaking the loop in a manner that cannot be easily repaired in the field.
- the connection mechanism may be located in any feasible place between the two contacts of RPID tag 390, including on the support 370.
- loop 380 may take the form of an insulated wire, with an electrically conductive inner core covered by a non-conductive surface to prevent the core from making electrical contact with metal doors.
- Electrically conductive loop 380 may include conductive paths on or in support 370, and the point at which the conductive loop 380 is likely to break may likewise be anywhere along the conductive loop 380, including portions of support 370.
- the illustrated embodiment shows loop 380 passing through two door handles, other configurations are also possible, provided the mechanical arrangement is such that once the loop is in place, opening the container will cause the electrical continuity provided by the loop to break.
- Fig. 4 shows a container with an RFID tag and an environmental change indicator, according to an embodiment of the invention.
- the illustrated embodiment shows a bottle (or jar or other container) 410 with a cap 420 that can be used to seal the contents within the bottle.
- the lid may provide a pressure seal when the Hd is firmly secured, so that if the lid is initially closed with the interior of the bottle under high pressure, evidence of a change of that pressure (such as to normal atmospheric pressure) would indicate that the bottle has since been opened.
- the illustrated embodiment shows an RFID tag 430 electrically connected to a pressure sensor 440.
- the pressure sensor 440 may close its internal electrical switch when the pressure sensor is subjected to high ambient air pressure, and open the switch when the pressure sensor is subjected to normal air pressure.
- the response from the RFID tag may indicate the state of the pressure in the bottle, and thereby indicate whether the bottle has been opened.
- a bottle may be sealed under low pressure, and the sensor may indicate whether the pressure in the bottle is still low, or is normal indicating the bottle has possibly been opened.
- Fig. 4 and the associated text describe a pressure sensor
- other types of sensors may be used to indicate other environmental factors, such as but not limited to: 1) temperature (e.g., a melted fuse to indicate the contents were subjected to high heat, 2) radiation (e.g., a radiation dosimeter to indicate exposure to radiation), 3) a biological sensor (e.g., a biohazard detector to detect leakage of biological specimens from a smaller sealed container within the larger sealed container, 4) etc.
- a sensor might produce a change of electrical resistance, which could then be measured directly and converted into a digital reading. The reading, or an indicator of the reading, could then be transmitted along with the tag's identification number. In a similar manner, the digital reading might be compared to a reference value, and the comparison then used as an indicator of a change of conditions.
- Fig. 5 shows a flow diagram of a method performed by an RFID tag, according to an embodiment of the invention.
- a poll may be received by the RFID tag.
- the status of the security sensor may be determined (e.g., is there electrical continuity through the sensor?), and at 530 the RFID tag may transmit digital data comprising the RPID tag's identification code and the status of the security sensor.
- Fig. 6 shows a flow diagram of a method performed by an RFID reader, according to an embodiment of the invention.
- the RFID reader may transmit a poll.
- the poll may be a general purpose signal intended to trigger a response from any RFID tag within range that is able to receive the signal and respond to it.
- the poll may be intended for one or more specific RFID tags (e.g., by transmitting a destination address in the poll).
- a response from an RFID tag may be received at 620.
- the response may be processed by determining the identification code included in the response and by determining the security status that may be included in the response. [0028] If the received status indicates a first state, the container to which the responding RFID tag is attached may be assumed to have not been tampered with, and normal processing may continue. Such normal processing may include registering the presence of the container at 660.
- registering may include noting that the container has been received at a dock, and a presumption may be made that the original contents of the container are still intact.
- the container may be assumed to have been possibly opened, and an alert may be generated at 650 to prompt further inspection of the container.
- the alert may take any feasible form, such as but not limited to any one or more of the following: 1) a visual warning indicator on an operator's video display, 2) an audible sound, 3) a message transmitted through wired or wireless means, 4) generation of control signals to secure the area, 5) etc.
