METHOD TO DETECT LOCK BOX SHACKLE BREAKAGE OR ATTEMPTED BREAKAGE AND ACTIVATE ALERT

BACKGROUND

The embodiments herein generally relate to lock boxes and more specifically, a method and apparatus to detect tampering with the lock box.

Lock boxes are typically used to a provide a secured storage area for a property access tool (e.g., key, the access card, or other access aid) at a location close to a locked property (e.g., at a front door to a residential home) accessible by the property access tool. In this way, an authorized user can unlock the secured storage area, obtain the property access tool and then use the property access tool to unlock the locked property. Although the locked property may be a residential home, it is envisioned that the locked property may be any space that is locked while unattended by a traditional lock that requires a property access tool. For example, the locked property may be a commercial or industrial site, or other type of property.

The lock box is typically attached to a door handle or to another stationary object near the traditional lock. The lock box is typically configured to require the user to demonstrate that the user is authorized to obtain access to the locked property before the secured storage area is unlocked to allow the user to obtain the property access tool. In a mechanical lock box, the user might be required to enter a correct lock combination to access the secured storage area. In an electronic lock box, the user might be required to communicate a credential to the lock box (via a physical connection to the lock box or via a wireless link to the lock box) to access the secured storage area.

DETAILED DESCRIPTION

A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

Embodiments disclosed herein relate to an apparatus and method to detect lock shackle breakage or attempted breakage. While conventional lock boxes are tough and very difficult to damage or break, attempts are still made to remove the lock box from a door handle. The embodiments disclosed herein seek to provide a detection and alert system to detect when a lock box break-in is attempted and then transmit an alert.

FIG. 1 is schematic view of a representative restricted range lock box and access key system 100, according to an embodiment of the present disclosure. A lock box 200 with wireless communications capability is shown in relation to an access device, which in this example is a mobile computing device 600. The mobile computing device 600 may be a portable computing device that is typically carried by a person, such as, for example a phone, a smart phone, a PDA, a smart watch, a tablet, a laptop, or any other mobile computing device known to one of skill in the art.

The restricted range of the lock box 200 is shown schematically at 130. Thus, the mobile computing device 600 as shown in FIG. 1 is outside of the lock box's operating range 130, and would need to be moved within the range 130 to communicate with the lock box 200.

Communications between the lock box 200 and the mobile computing device 600 may be two-way, as indicated by the two-way arrow representing a communications link 115. The communications link 115 may be infrared, Bluetooth, Low-Energy Bluetooth, Near Field Communication (NFC), or any other similar communication method known to one of skill in the art. In some cases, one-way communication from the mobile computing device 600 to the lock box 200 may be sufficient.

All of the conventional lock box functions may be supported. For example, the communications from the mobile computing device 600 to the lock box 200 can include the ability for the user of the mobile computing device 600 to make an access request directed to the lock box 200. This access request may include communication of a credential indicating that the user is authorized for access.

In response, the lock box 200 may communicate a message, either via a display on the lock box or via a message transmitted to the mobile computing device 600, denying access. Access may be denied, e.g., if the user is unauthorized, if the user's credentials have expired, or if the access privileges have been superseded (e.g., if the property owner has overridden access privileges or is invoking the call before showing feature).

If access is granted, the lock box 200 allows the user to gain access to a storage area 290 (FIG. 2) in the lock box 200 or open a shackle 210 for removing the lock box 200 from an object to which it is attached (e.g., a door). In specific implementations, the lock box 200 has a circuit that controls a lock mechanism that secures the storage area 290 and shackle 210 in a locked condition when in use. When an access request is granted, the circuit unlocks the lock mechanism to provide the user access to the storage area 290, the shackle, or both. The internal components of the lock box 200 and the storage area 290 are protected from the external environment by an outer cover 202. The outer cover 202 may be composed of a tough durable material to prevent, or at least impede, someone from breaking into the lock box 200 and removing the key or the access card in the storage area 290.

Optionally, the access key system 100 may also include an authorization authority 140, which can be linked to the lock box 200 (via a link 145), or to the mobile computing device 600 (via the link 150) or to both the lock box 200 and the mobile computing device 600. The authorization authority can administer granting credentials to users, collect information on usage and activity and provide for updates to devices (lock boxes and access devices) in the access key system 100.

There are a number of possible ways to implement restricted range wireless communications by which the communicating devices are magnetically coupled. As only one example, the devices can be configured according to the Near Field Communication standards.

NFC is described as a standards based, short range wireless connectivity technology that enables simple and safe two-way interactions among appropriately configured electronic devices. Near Field Communication is based on inductive-coupling, where loosely coupled inductive circuits share power and data over a distance of a few centimeters. NFC devices share some similarities with proximity (13.56 MHz) RFID tags and contactless smartcards, but have a number of new features.

NFC is described as being fast, private, and easy as compared to other wireless standards. The NFC set-up time is less than 0.1 millisecond, which is much less than the Bluetooth set-up time of about 6 seconds and less than the IrDa set-up time of about 0.5 second. The NFC operating range is 10 cm or less, which is shorter and provides for more privacy than RFID (operating range up to 3 meters) and Bluetooth (up to 30 meters). At the same time, NFC is more convenient than IrDa which requires line of sight alignment for communication between devices, whereas NFC requires only that the devices be within the NFC operating range of each other. Thus, NFC is one communications technology ideally suited to implementing a restricted range lock box. In addition, RFID is largely limited to item tracking, and Bluetooth is comparatively more difficult to use because some configuration of the device is required.

NFC operates at 13.56 MHz and transfers data at up to 424 Kbits/second (current data rates are 106 kbps, 212 kbps and 424 kbps). The 13.56 MHz band is not currently regulated, so no license is required. NFC is both a “read” and “write” technology. NFC devices are unique in that they can change their mode of operation to be in reader/writer mode, peer-to-peer mode, or card emulation mode. In reader/writer mode, an NFC device is capable of reading NFC tag types, such as in the scenario of reading an NFC Smartposter tag. The reader/writer mode is on the RF interface compliant with the ISO 14443 and FeliCa schemes. In Peer-to-Peer mode, two NFC devices can exchange data. For example, Bluetooth or Wi-Fi link set up parameters can be shared, and/or data such as virtual business cards or digital photos can be exchanged. Peer-to-Peer mode is standardized on the ISO/IEC 18092 standard. In Card Emulation mode, the NFC device itself acts as an NFC tag (which is a passive device that stores data), appearing to an external reader much the same as a traditional contactless smart card. This enables, for example, contactless payments and eticketing.

Communication between two NFC-compatible devices occurs when they are brought within operating range of each other: a simple wave or touch of a device can establish an NFC connection, which is then compatible with other known wireless technologies such as Bluetooth or Wi-Fi. Because the transmission range is so short, NFC-enabled transactions are inherently secure. Also, the required physical proximity of one device to another is intuitive and gives users the reassurance of being in control of the process.

The underlying layers of NFC technology follow ISO/IEC (International Organization for Standardization/International Electrotechnical Commission, ECMA (European Telecommunications Standards Institute), and ETSI (European Telecommunications Standards Institute) standards. NFC compliant devices in the NFC Reader/Writer mode must support the RF requirements for ISO/IEC 14443A, ISO/IEC 14443 B and FeliCa as outlined in the relevant parts in the ISO 18092. As of this time, there are five published NFC specifications: Smart Poster Record Type Definition (RTD); Data Exchange Format; Record Type Definition; Text RTD and URI RTD. NFC devices are naturally interoperable, as NFC is based on pre-existing contactless payment and ticketing standards that are used on a daily basis by millions of people and devices worldwide. These standards determine not only the “contactless” operating environment, such as the physical requirements of the antennas, but also the format of the data to be transferred and the data rates for that transfer.

Because NFC components are generally smaller, the size of the access device can be kept small, which increases convenience. Also, the size of the lock box can be reduced.

It is understood that embodiments described herein are not limited to the communication link 115 between the lock box 200 and the mobile computing device 600 being NFC, and the embodiment described herein may be applicable to other communications links 115 between the lock box 200 and the mobile computing device 600 including but not limitation to infrared, Bluetooth, Low-Energy Bluetooth, or any other similar communication method known to one of skill in the art.

The alert 502 may alternatively be saved and then transmitted directly to the mobile computing device 600 via a short-range wireless transmission 501 when the mobile computing device 600 is within range of the controller 330. The alert 502 may generate a message 710 to be displayed on the display device 680 of the mobile computing device 600. The message 710 may state “ALERT!!Attempted Lock box tampering!!” or a similar message. The message 710 may also include identification information 720 for the lock box 200, which advantageously would help if the individual 504 is managing multiple lock boxes 200. The identification information 720 may include a name or number of a lock box 200 and a location of the lock box 200. The alert 502 may also specify whether the mounting location 822 or the shackle 210 is being attacked. The alert 502 may also be able to vibrate the mobile computing device 600 and/or activate an audible alarm on the mobile computing device 600, via the feedback device 660. The alert 502 may also adjust an indicator light 201 on the lock box.

At block 806, it is determined whether the magnitude of the force exceeds a selected magnitude. The selected magnitude being a predetermined force that indicates an individual is tampering with the shackle 210. At block 808, an alert 502 is generated if the magnitude of the force exceeds a selected magnitude.

The method 800 may further include that the alert 502 is transmitted to a mobile computing device 600. The method 800 may also include that it is detected when the mobile computing device 600 is within a short-range wireless transmission range of the lock box 200 and then the alert 502 to the mobile computing device 600 is transmitted when the mobile computing device 600 is within the short-range wireless transmission range of the lock box 200.

The method 800 may alternatively include that the alert 502 is transmitted to a home computing device 350 and the home computing device 350 is configured to relay the alert 502 to a mobile computing device 600 via the internet 306. The method 800 may yet further include that an indicator light 201 on the lock box 200 is adjusted based on the alert 502.

While the above description has described the flow process of FIG. 4 in a particular order, it should be appreciated that unless otherwise specifically required in the attached claims that the ordering of the steps may be varied.
