Threat scanning machine management system

Abstract

Disclosed is a dynamically configurable threat scanning machine management system that utilizes a network to connect threat scanning machines with a central control computer. The central control computer can transmit, among other things, operational software and threat profiles to the threat scanning machines, while the threat scanning machines can transmit, among other things, images and performance data to the central computer. The threat scanning machine management system can be arranged in a hierarchical manner, which enables threat scanning machines at various locations to be connected into regional, national or international control centers for greater management efficiency. The network may be wireless and the control computer may be portable, enabling a supervisor to remotely manage the threat scanning machines while remaining mobile about the facility, or elsewhere. Additionally, the threat scanning machine management system can be accessed and monitored remotely from a web browser via secure Internet access.

Description

The present invention relates generally to system management, and, more particularly, to the management of threat scanning machines.

Threat scanning machines are often employed in locations where safety and security are at issue. Transportation facilities, for example, airports, train stations, seaports, and the like, may employ threat scanning machines to detect security threats within passenger or freight baggage. Other facilities, such as office buildings, government buildings, court houses, museums and the like may employ threat scanning machines to detect restricted items being carried by a person seeking entry to the facility. A threat scanning machine, as used herein, refers to any device capable of detecting an object defined as a threat. A threat, as used herein, can be anything that is restricted from being brought aboard a vehicle, into a building or into an area.

Threat scanning machines may be of different make and model, including carry-on bag scanning machines, checked-bag scanning machines, walk-through metal detectors, x-rays, computerized tomography devices, magnetic resonance imaging devices, and the like, thus requiring individualized maintenance and control of each machine's software and data components. The task of individually maintaining and controlling each machine may be time consuming, prone to error and expensive. For example, when supervisor attention is required at a particular machine, the supervisor must physically go to the machine, assess the situation and provide guidance to the threat scanning machine operator. As another example, when the software in an existing threat scanning machine needs to be upgraded, the media containing the upgrade may be required to be carried from machine to machine in order to perform the upgrade. The diversity of threat scanning machine types and the varied locations of threat scanning machines pose obstacles to the efficient management of the threat scanning machines.

In an exemplary embodiment of the threat scanning machine management system, the threat scanning machines are connected to a communication network. One or more control center computers are connected to the communication network. The threat scanning machines, possibly of different make and model, are adapted with hardware and software to allow them to communicate over the network with the control center computer. The control center computer is adapted with software and/or hardware to control and manage threat scanning machines. In another exemplary embodiment of the present invention, t-he control computer can transmit data, such as, for example, operational software and threat profiles to the threat scanning machine; and the threat scanning machines may transmit data, such as, for example, images and performance data to the control computer.

In yet another exemplary embodiment of the present invention, a supervisor may view the images or performance data of a threat scanning machine remotely on the control center computer, assess the situation and assist the threat scanning machine operator remotely, thereby permitting the supervisor to manage multiple threat scanning machines in an efficient manner. In still another exemplary embodiment of the present invention, the threat scanning machine management system may be dynamically configurable, the network may be a wireless network, and the control center computer may be a portable device, thus permitting a superior to manage the threat scanning machines while remaining mobile.

Thus, it should be appreciated that the components of the threat scanning machine and the command and control center, respectively, can be combined into one or more devices or collocated on a particular note of a distributed network, such as a telecommunications network. As will be appreciated from the following description, and for reasons of computational efficiency, the components of the communications network can be arranged at any location within the distributed network without affecting the operation of the system. Also, the exemplary embodiments shown provide a layout of the system in which the subsystems (i.e. Threat Management, Remote Management, and Maintenance Server) are shown separately for conceptual clarity and for illustrative purposes in both the threat scanning machines and the command and control center. However, it should be appreciated, that other layouts, groupings, and/or arrangements of the subsystems within the system can be used.

Furthermore, it should be appreciated that the various links connecting the elements can be wired or wireless links, or a combination thereof, or any known or later developed element(s) that is capable of supplying and/or communicating data to and from the connected elements.

FIG. 1 shows a functional block diagram of an exemplary embodiment of a threat scanning machine management system 100. In particular, a command and control center 102 forms a top level of a system hierarchy and is interconnected by a network 112 to a next level comprising command and control centers 104. A command and control center 104 is interconnected with a threat scanning machine 106 by the network 112. A command and control center 104 is interconnected to command and control center 108 and to command and control center 110 via the network 112. A command and control center 110 is interconnected to one or more threat scanning machines 106 via the network 112.

The threat scanning machine management system 100 shown in FIG. 1 represents, for purposes of illustration, an exemplary configuration of command and control centers connected to each other and to threat scanning machines. However, it should be appreciated that the system 100 can be configured in order to be adaptable to various contemplated uses of the present invention. The configuration of the system 100 may be static or dynamic depending on contemplated uses of the invention. In an exemplary embodiment, a transportation facility may have an existing network (not shown), and in such a case, the threat scanning machine management system 100 may be adapted to the existing network. Alternatively, in another exemplary embodiment, if an existing network within a transportation facility is insufficient to be able to adapted to meet the communications requirements of the threat scanning machine management system 100 for any reason, such as low bandwidth or poor security, for example, then a new network can be installed for the threat scanning machine management system 100 to communicate over. However, it should be appreciated that any communications medium that allows the threat scanning machines and the control centers to communicate may be used with equal success. In an exemplary embodiment of the invention, the command and control centers and the threat scanning machines communicate over the network 112 using standard protocols common in the industry. Examples of standard protocols include, for example, HTTP, IIOP, RMI, SMTP, SSL, SHTTP and the like. Examples of a network 112 include wired or wireless solutions such as Ethernet, fiber optic, or the like. However, it should be appreciated that any present or future developed networks and/or network protocols which perform the tasks required for a command and control center to communicate with a threat scanning machine may be used with equal success according to the present invention.

In operation, the exemplary command and control center 110 communicates with one or more threat scanning machines 106 via the network 112. The command and control center 110 may transmit data to the threat scanning machine, for example, operational software, authorized users and credentials, threat profiles, etc. The operational software may comprise any combination of software for the operation of the scanning system and/or software for the operation of the management system 100. The authorized users and credentials, which may include, for example, a list of user login names and passwords. Threat profiles may include data that the threat scanning machine uses to aid in identification of threats, for example the shape of potential threat items, and/or the physical properties of an item that may indicate a potential threat. However, it should be appreciated that the data transmitted from the command and control center 110 to the threat scanning machine 106 may be any data required for the management and operation of the threat scanning machine and could be used with equal effectiveness according to the present invention.

The exemplary threat scanning machine 106 communicates with the command and control center 110. The threat scanning machine my receive data from the command an control center 110 and/or may transmit data to the command and control center 110. The data that the threat scanning machine may transmit to the command and control center 110 may include, for example, performance data, requests for operator assistance, threat detection data, and/or the like.

The exemplary command and control center 110 may communicate with one or more command and control centers 104 and/or 102. In the exemplary embodiment shown in FIG. 1, the command and control centers 110 are interconnected to command and control centers 104. The command and control centers 104 are interconnected to command and control center 102. In this exemplary embodiment and configuration of the present invention control centers are arranged in a hierarchical manner to provide for the centralized management of many threat scanning machines 106 from a central command and control center 102, thus providing more efficient management of the threat scanning machines 106.

FIG. 2 is a functional block diagram of an exemplary embodiment of a threat scanning machine management system. In particular, a command and control center 104 at one level is interconnected with a command and control center 110 of another level. The command and control center 104 comprises, in addition to standard control center components, a threat management module 206, a remote management module 208 and a maintenance server module 210. The exemplary command and control center 110 comprises, in addition to standard control center components, a threat management module 222, a remote management module 224 and a maintenance server module 226. The exemplary command and control center 110 is interconnected to one or more exemplary threat scanning machines 106.

The exemplary threat management module 212, remote management module 214, and maintenance server module 216 are adapted to provide the interface and logic necessary for the threat scanning machine 106 to be connected to the maintenance and control system; these modules also communicate with the scanning system interface module 218. In an exemplary embodiment, the threat scanning machine computer 202 may be a standard PC. In another exemplary embodiment, the threat scanning machine computer 202 may be a specialized computer adapted specifically to control the threat scanning machine 106.

In yet another exemplary embodiment of the present invention, the threat scanning machine management system 100 may be designed to adapt to any existing threat scanning machine computer 202 in order to allow the threat scanning machine 106 to connect and communicate within the threat scanning machine management system.

In still another exemplary embodiment of the present invention, the system interface module 220 can be housed in a computer separate from the threat scanning machine computer 202; this construction may be useful in situations where the execution of the system interface module 220 may present too great a processing and/or communications burden for the threat scanning machine computer 202.

In operation, the exemplary threat management module 206 of the command and control center 104 communicates with the threat management module 222 of the command and control center 110. The threat management module 222 of the command and control center 110 communicates with the threat management module 212 of the threat scanning machine 106. The threat management information comprises any information related to the management of threats. Examples of such information include Threat Image Projections (TIP), which are non-threat images with threats inserted into them for testing purposes, threats detected within a particular piece of baggage, or messages alerting the threat scanning machine operators to specific or general types of security risks that may be present or that may be attempted.

The exemplary remote management module 208 of the command and control center 104 communicates with the remote management module 224 of the command and control center 110.

The maintenance server module 226 of the command and control center 110 communicates with the maintenance server module 216 of the threat scanning machine 106.

The command and control center 110 and the threat scanning machine 106 may communicate with each other using a predefined interface format. A predefined format allows for the command and control center 110 to be connected to any threat scanning machine 106 that has been adapted to work in accordance with the present invention. The tables below provide an example of a predefined interface between the command and control center 110 and the threat scanning machine 106. However, it should be appreciated that these tables merely represent an exemplary interface for illustration purposes.

Table 2 shows the contents of an exemplary Operator Bag Information message. The Operator Bag Information message provides the command and control center 110 with information relating to a particular piece of baggage that has been scanned by the threat scanning machine 106.

In operation, the Operator Bag Information message is used to transmit information gathered by an operator on a particular bag. A supervisor or screener can review the Operator Bag Information message in assisting the operator in assessing a potential threat. Another use of the Operator Bag Information message may be to monitor the performance of an operator by placing a test bag containing a known threat or threat-like object in order to evaluate the operator's performance in identifying and assessing the potential threat. A further use of the Operator Bag Information; message is to collect the messages over time in order to form statistical models of the operator bag information. These statistical models may then be used to further enhance the operation of the threat scanning machine management system.

Table 3 shows the contents of an exemplary Screener Bag Information message. The Screener Bag Information message provides the command and control center 110 with information from a particular screener about a particular piece of baggage.

In operation, when a threat scanning machine and/or operator detect a potential threat, a screener may be called upon to search the bag physically. The Screener Bag Information message is used to transmit information gathered by a Screener on a particular bag, such as the results of the physical search, threats found or not found, and any action taken by security with regard to the passenger or the baggage. A supervisor can review the Screener Bag Information in assisting the screener and operator in assessing and dealing with a potential threat. Another use of the Screener Bag Information message may be to monitor the performance of a screener by placing a test bag containing a known threat or threat-like object in order to evaluate the screener's performance in identifying and assessing the potential threat. A further use of the Screener Bag Information message is to collect the messages over time and correlate them with other system data, such as operator bag messages, in order to form statistical models of the screener bag information. These statistical models may then be used to further enhance the operation of the threat scanning machine management system.

An important aspect of the present invention, achieved through the operator and screener bag information messages, is that baggage may be tracked and associated with a particular person as that person moves about from place to place. For example, the information about a particular person's bag may be gathered as the person travels from location to location. The threat scanning can then be augmented with historical bag information data in order to further inform the operator, screener, or supervisor of the need for further inspection of the bag. Additionally, the baggage may be associated with an owner or carrier and vice versa, thereby permitting the threat scanning machine management system to enhance the threat scanning with auxiliary information about the owner or carrier to further enhance the security.

Table 4 above shows the contents of an exemplary Threat Information message. The Threat Information message provides the command and control center 110 with information about a particular threat detected by the threat scanning machine 106.

In operation Threat Information messages may be transferred to the command and control center for assistance in assessment by a supervisor. Additionally the supervisor in the command and control center may pass the message along to a more senior supervisor at a regional or national level command and control center. Further still, the system can be configured to automatically forward messages to higher levels in the hierarchy based on preselected or dynamic criteria, such as threat type or threat category. In this manner a threat that once was only able to be viewed and assessed on site, may now be able to be assessed by numerous people with possibly increasing levels of expertise, thereby by making efficient use of the supervisor's time through a hierarchical system of review and assessment of potential threats. This process can be carried out in a very expeditious manner through the interconnection of the threat scanning machine and the command and control centers on a distributed network. A further use of the Threat Information message is for the threat management system as a whole to scan for incidents of like or similar threats and alert supervisors and threat scanning machine operators to patterns in the data which may indicate a security breach is being attempted. Still another use of the Threat Information message is to gather information on things that have been identified as threats, but in actuality are only items of interest for purposes other than security. For example, the threat scanning machine could possibly be configured to monitor for aerosol cans within baggage and record statistics related to their occurrence in the baggage. This type of statistical information on “threats” could be used to guide policies regarding acceptable items, for general research into items in baggage, or for other such purposes. In yet another use of the Threat Information messages, the data may be collected over time and used to build statistical models of potential threats and their rates' of occurrence. These statistical models could be fed back into the threat management system in order to improve the accuracy, security, and management efficiency of the threat scanning machine management system.

Table 5 shows the contents of an exemplary Alarm Information message. The Alarm Information message provides the command and control center 110 with information about a particular alarm from the threat scanning machine 106.

In operation the Alarm Information messages provide information useful to achieving management goals. As a current situational awareness indication, the Alarm Information may be transferred both vertically (i.e. from threat scanning machine to command and control center and on up the chain of command and control centers) and horizontally (i.e. threat scanning machine to threat scanning machine) in order to inform management and other operators of threat events in a real time manner. This real time reporting of threat event information makes an added dimension in security response possible, namely one of recognizing a looming security risk that may be geographically disbursed. By utilizing threat scanning machine management systems in multiple countries it would even be possible for nations to collectively detect and recognize a global security threat event that was in the early stages of being carried out. By collecting Alarm Information messages over time, statistical trends may be analyzed to aid management in improving the efficiency and security of the threat scanning machines.

Table 6 shows the contents of an exemplary Event Information Message. The Event Information message provides the command and control center 110 with information about a particular event that occurred at a threat scanning machine 106.

In operation the Event Information messages provide information useful to achieving management goals. As a current situational awareness indication, the Event Information may be transferred both vertically (i.e. from threat scanning machine to command and control center and on up the chain of command and control centers) and horizontally (i.e. threat scanning machine to threat scanning machine) in order to inform management and other operators of threat events in a real time manner. This real time nature of the reporting of threat event information brings a new dimension in security response, namely one of recognizing a looming security risk that may be geographically distributed. By collecting Event Information messages over time, statistical trends may be analyzed to aid management in improving the efficiency and security of the threat scanning machines.

Table 7 shows the contents of an exemplary User Keystroke Information Message. The User Keystroke Information Message provides the command and control center 110 with details from the threat scanning machine 106 regarding the keystrokes of a user in the processing of a particular piece of baggage.

In operation, the User Keystroke Information message can be used for several management and supervisory purposes. The keystroke information may be used as a training aid by permitting supervisor to oversee the keystrokes used by a scanning machine operator and determine if the operator has used the scanning effectively, or if further training is needed in a particular area. Further, the keystroke information may be collected over time to study the efficiency of the threat scanning machine operators. Further still, the keystroke information may provide additional details to a supervisor who is assisting a scanning machine operator with a possible threat presence. Yet another use of the keystroke information may be to correlate the keystroke information with the image data and recreate, or playback, what took place at a particular machine to look for suspicious activity by the operator or as an aid in analyzing machine performance and debugging the threat scanning machine software.

An important aspect of the threat scanning machine management system is that is a system for managing both the threat scanning machine equipment and the personnel operating the threat scanning machines.
