Description

CONTAINER SEAL SECURITY DEVICE
TECHNICAL FIELD OF THE INVENTION
This invention relates to a tamper indicating device for the management of assets including containers.
BACKGROUND ART
The integrity of a container is of paramount importance having regard to theft or the importation of dangerous matter such as explosives, poisons, radioactive material and the like. Many ideas have been propounded to eliminate or at least reduce the risk of containers and trucks having their contents stolen or bearing illicit goods without an indication, or only a delayed indication, of the breakage of the seal or seals of the container. It is often a situation of locking the door after the horse has bolted.
In USP 6331022 a cable seal is provided that seals the container and locks the security bar. In US 6536815 the bar and bracket are covered in a textured baked-on powder coat. A thief may cut the bar and try to weld it together again to disguise the fact that the bar had been cut. Both of these patents rely on a visual check and therefore to human error.
In USP 7019683 a container includes a system that senses an intrusion into the container. The sensing is provided by range-gated micro- impulse radar that generates microwave pulses that bounce around the interior of the container and the reflected signals are measured at the exit gate. The system relies on the Doppler Effect and is complicated and, as far as the applicant is aware, has not been used extensively if at all.
Terminal management systems (TMS) used at present includes a camera-captured photograph of the container ID and of the truck ID. Unfortunately, the camera cannot capture the locking bolt seal ID number because of its small size, and this requires a close-up visual inspection and recordal. This adds time to the clearing facility of the check point and, in instances in which there are two containers on the same truck and their doors are facing each other, the visual inspection is very difficult if not impossible. This means that it is extremely difficult to confirm whether or not the locking bolt seal has been replaced or tampered with.
It is an object of the present invention to provide a system that avoids or at least greatly minimises the difficulties and problems outlined above.
DISCLOSURE OF THE INVENTION
According to the invention a tamper indicating device for a seal for a container includes a locking unit adapted to span a conventional locking bolt (or other container seal), and having a RFID facility linked electronically with at least one identity code associated with the locking bolt and/or the container number .
The device may have a unique secure encrypted electronic ID embedded in the RFID microchip or the like that may also be embossed on the unit for visual purposes, if necessary.
The device ID along with other information may be linked to the locking bolt identity code on a backend operating platform
In a preferred form of the invention the device has at least one RFID component having an ID code readable by a RFID reader.
The device includes a zone that is fracturable whereupon the ID code becomes unreadable on attempts to tamper with the device.
In the event that the ID becomes unreadable, the system may be immobilised for "No Read" by the reader to indicate an unauthorised fracture of the device. The device of the invention effectively shields the locking bolt or other seal and obviates the previous requirement for a visual inspection.
The device may be self-locking so that it can only be removed by cutting or other force, and thereby fracturing it.
The device of the invention may be used with most systems worldwide thereby providing adequate security for intercontinental movement.
In an example of the invention the RFID may comprise or include a 32- bit authentication identifier, with an extensible EPC memory bank, a scalable user memory bank and a password-protected read and write support capabilities.
The device of the invention is preferably supplied and affixed by the packer of the particular container. Check points, such as harbour or yard terminals will be equipped for reading the devices, and it will be appreciated that it is not possible to counterfeit any device because of the use of a large number, for example 32 bit codes.
The RF communication interface and reader commanded functionality requirements are preferably for Class 1 RFID tag operating in the frequency range of 860-930 MHz. A Class 1 tag is designed to communicate only its unique identifier and other information required to obtain the unique identifier during the communication process.
In use a fixed RFID reader is located at strategic points, such as a port entrance, exit, yard entrance and exit as well as boundary or customs posts.
The device data may be relayed to a central point which preferably has an interface with the Terminal Management System, Customs, SARS. BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment of the invention is described below with reference to the accompanying drawings, in which:
Figure 1 is an exploded view of the device according to the invention;
Figure 2 is a view of an adapter for use with different shaped locking bolts; Figure 3 is a view of the RFID chip located on the slidable insert;
Figure 4 is an isometric view showing the device in position of use.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to figures 1 to 4 the device 10 includes a holder 12 for the tag 20 of a locking bolt 22 and a slidable insert 14, receivable in the holder 12, for lockingjhe tag of the locking bolt 22 in position.
Referring to figure 1 , the slidable insert 14 includes ratchet formations 16 engagable with complimentary ratchet formations 18 on the holder 12 thus forming a locking engagement with the holder 12.
The slidable insert 14 additionally includes a fracturable zone 24.
The device 10 is intended for a single use, and once locked in place, must be broken to be removed.
Referring to Figures 1 and 3, the circuitry 30 of the device 10 is contained within the slidable insert 14. The circuitry 30 includes an RFID microchip, having a unique secure encrypted electronic ID. The RFID microchip is a Class 1 tag and includes a 32-bit authentication identifier, with an extensible EPC memory bank, a scalable user memory bank and password-protected read and write support capabilities. A Class 1 tag is designed to communicate only its unique identifier and other information required to obtain the unique identifier during the communication process. Any attempt to tamper with the device 10 to obtain access to the locking bolt 20, 22 will result in the insert 14 being broken along its fracturable zone 24, subsequently causing the circuitry 30 of the device to be broken.
Referring to figure 2, an adapter 38 is available for those locking bolts 20, 22 that are shaped slightly differently to the device holder.
Referring to figure 4, the locking bolt 22 is used to lock the security bar of the container (not shown), and is then secured in the holder 12. The identity number of the bolt is shown at 36. The ID number of the device is also printed onto the device at 32.
In use the device 10 is supplied and affixed by the packer of the particular container.
The packer will then load information about the container onto a user platform, including the device ID number, the locking bolt ID 26 and the container number.
A fixed RFID reader is located at strategic points, such as a port entrance, exit, yard entrance and exit as well as boundary or customs posts. When the device is in the range of a reader, it will be prompted for an ID.
If the device is damaged or not present, the ID will not read, and information will be transmitted to the reader, alerting the relevant persons that the device has been tampered with.
Where an RFID user is not present, it may be possible to use a WAP/internet enabled cell phone to match the information. This information may then be transmitted to the backend user platform. The backend user platform will then send a response back to the phone providing the original locking bolt 20 ID number 26 and the original container number. These numbers can then be checked against the actual locking bolt 20, 22 ID number 26 and the container number present. Any discrepancies between what is recorded on the back end user platform, and what is actually present on the device will indicate that the container has been tampered with and a new device applied.
The RFID chip has a unique number which can be linked to the bolt seal as well as container via the operating platform. This data may be relayed to a central point which preferably has an interface with the Terminal Management System, Customs, SARS.
The invention therefore provides for a unique tamper indicating device.
