Target Recognition using Artificial Intelligence (TRAI)
Description |
The project “Target Recognition using Artificial Intelligence” (TRAI) evaluates chances and risks of AI systems for the automated detection of prohibited items in X-ray images (APIDS). Currently, first such systems are commercially available. These systems have a big potential to increase security in aviation. However, it is still unclear how well they actually perform for different threats and how the interaction between APIDS and security officers should be designed for optimal security and efficiency. TRAI aims at providing answers to these questions. |

ROBUST RISK BASED SCREENING AND ALERT SYSTEM FOR PASSENGERS AND LUGGAGE (TRESSPASS)
Description |
The overall scope of TRESSPASS is to modernize the way security checks at border crossing points (BCPs) are held out. TRESSPASS imports the idea of risk based security checks and proposes an analytic framework for modelling risk as well as a systematic approach of quantifying risk, based on a set of indicators that can accurately be measured across all four tiers of the Integrated Border Management. Once these indicators are accurately estimated from available data collected from background information, sensors and applications, the risk for each traveler is reliably calculated, based on the four-tier risk management approach introduced in TRESSPASS. Based on this risk, the system then adjusts the number and types of security checks required for each traveler, congruent with the associated risk, in order to maintain a desired security level while optimizing security. Special attention is paid in maintaining a level of mutual trust between the security process and the traveler throughout the entire screening process. Extensive simulations will be used to first test the proposed approach before implementing and validating it in three different pilots covering all three modalities: land, maritime, and air.

Aviation Security Systems: Unpredictability Measures Evaluation (ASSUME)
Description |
Aviation security measures tend to be predictable, especially for insiders. This can produce severe vulnerabilities in the security level making it potentially easier to circumvent the measures. A project headed by Zurich State Police, Airport Division, was conceived in collaboration with CASRA and the Federal Institute of Technology Zurich (ETHZ) to address this aspect. Within it, basic and applied research is conducted on the impact and mechanisms of unpredictable measures in aviation security on risk perception and risky behavior. A long-term reduction of insider threat is sought through the evaluation and optimization of existing security measures. A central contribution of CASRA to the project is intelligence research and development. |

COMPUTER-BASED TESTS FOR CERTIFICATION OF AVIATION SECURITY SCREENERS IN SWITZERLAND
Description |
Certification and competency assessment of airport security screeners have become very important topics in the last few years. A common certification procedure helps to achieve comparable standards across different airports and countries. On behalf of this project computer-based tests are used to measure ability and competency of airport security screeners in six Swiss airports. The Object Recognition Test (ORT) is used to assess screener ability needed for recognizing threat items in rotation, when they are superimposed by other objects and placed in close-packed bags. The X-Ray Competency Assessment Test (X-Ray CAT) is used to assess visual knowledge about prohibited items. A theoretical exam on computer (TEC) is applied to test the theoretical knowledge required in airport security screening procedures. The results provide a solid basis for a reliable and standardized certification procedure performed by the Swiss airports in collaboration with the Swiss Federal Office of Civil Aviation (FOCA). |

INCREASING SECURITY AND EFFICIENCY AT ZURICH AIRPORT
Description |
In the last decade large investments have been made into aviation security technology. However, the most expensive equipment is of small value if the humans that operate it are not selected and trained to perform their task accurately and efficiently. In this project security and efficiency is increased by (1) applying reliable tests for pre-employment assessment, (2) by using individually adaptive training (X-Ray Tutor), and (3) by implementing TIP. In this project the data for assessing the effectiveness of these instruments are analyzed. Additionally, different basic and applied aspects of the object detection and visual cognition are examined. |

2D VS. 3D X-RAY IMAGE DISPLAY STUDY
Description |
While currently state-of-the-art X-ray machines employed at airports for hold baggage screening display static 2D single or multi-view X-ray images, new developments in X-ray screening technology offer 3D rotatable X-ray images, allowing screeners to view a bag from different angles. The purpose of this study is to evaluate this new technology and its effects on the screeners’ detection performance in hold baggage screening (HBS). More specifically, it is investigated if threat detection performance differs significantly between screeners when they analyze X-ray images in single view 2D vs. 3D rotatable X-ray images. If detection performance is significantly better when images are analysed in 3D compared to 2D single view, results imply that viewing baggage with 3D rotatable images provides a significant benefit to the screeners. Furthermore, the results of the project shall give an indication on how screeners who will work with 3D rotatable images for the first time are able to adapt to this compared to screeners who are already experienced in analysing 3D rotatable images. The project is being conducted by CASRA in collaboration with the German Federal Police. |

TESTING THE INFLUENCE OF MOTION IMAGING FOR THE INSPECTION OF LAPTOPS IN CABIN BAGGAGE SCREENING
Description |
Large amounts of money are being invested into the improvement and further development of new screening technologies, continuously aiming at improving image quality, automatic explosive detection and enhancing the detection of prohibited items for human operators i.e. screening officers. Especially the latter is of high importance, as the actual identification of prohibited items lies mainly in the hands of human operators. Thus, it is of great important to evaluate any new technologies and machines developed for screening purposes with regard to image quality and the actual benefits for the people that have to handle and work with these machines (i.e. man-machine-interaction). The aim of this project was to compare motion imaging (Array CT machine) to single view imaging with regard to detection performance. More specifically, it was investigated whether a significant difference in detection performance aroused when motion imaging was used and laptops were left inside passenger bags compared to the situation where only single view images were provided but laptops were taken out of passenger bags. |

ECAC BDS TESTING OF L-3 PROVISION 100 (MIKS)
Description |
In state-of-the art airport security screening, passengers have to walk through a metal detector before being allowed to board an aircraft. With bodyscanner technology it is possible since recently to screen passengers more accurately to examine whether they carry prohibited items on the body. The Technical Task Force of the European Civil Aviation Conference (ECAC) has created a Body Scanners Study Group (ECAC BSSG) in 2007. In a two years project, this group has developed a Body Scanner Testing Methodology (BSTM). The main aim of the BSTM is to test human-machine performance using body scanners for the detection of prohibited items carried by passengers. In this project, the BSTM was applied to test the L-3 ProVision 100 body scanner. This project was conducted to apply the BSTM (this was the first time world wide) and to refine the BSTM. The result of this project provided important information for using the BSTM for certification of body scanners in EU and ECAC member states. |

STUDY ON THE IMPACT OF DUAL VIEW AND AUTOMATIC EXPLOSIVES DETECTION IN HAND LUGGAGE SCREENING OF LAPTOPS
Description |
This study investigated the impact dual view and automatic explosives detection technology have on the performance of aviation security screeners who visually inspect hand luggage using X-ray screening systems. So-called “advanced cabin baggage X-ray screening” (ACBX) systems provide multiple X-ray views of bags and automated explosive detection. A recent study by von Bastian, Schwaninger and Michel (2008) has shown that multi-view X-ray technology can generate key benefits for the screening of hand luggage. One aspect of specific interest in the present study was whether or not it will be possible to leave laptops in a passenger’s hand luggage or whether laptops will continue having to be removed from hand luggage and be screened separately. It was found that ACBX systems have advantages under certain specific conditions, e.g. for the detection of rotated guns. However, leaving laptops in passenger bags cannot be recommended, even if ACBX technology is used. The results of the study have a substantial impact on aviation security regulations in Germany and other European member states. |

IDENTITY VERIFICATION FROM PHOTOGRAPHS IN TRAVEL DOCUMENTS: MEASURES OF PERFORMANCE ENHANCEMENT
Description |
At border control, it is the security personnel’s job to identify possible passport fraud, in particular to verify whether the photograph in a travel document matches its bearer. However, as various studies have shown, identity verification from document photographs is far from accurate. The aim of this project is thus to develop a procedure for security personnel to enhance identity verification performance from document photographs. In three studies, four factors shall be investigated: First, the reduction of time pressure in identity verification; second, the potential benefit of inversion of the document photograph on identity verification; third, the enhancement of sensitivity towards configural information contained in faces through training; and last, enlargement of the document photograph for better identity verification. All four factors are believed to be potentially beneficial on identity verification performance and could well influence standard verification procedures at border control. |

STUDY ON THE EFFECT OF CABIN BAG SIZE ON THE EFFECTIVENESS OF SCREENING
Description |
The aim of this project was to provide the basis for scientifically based conclusions about the significance of the bag size variable by itself and in relation with other variables. In this research project the effect of a number of variables including bag size, bag complexity, packing density, etc, on screener performance was investigated. For this, a set of X-ray images of cabin bags were captured, and presented in CBT format to screeners across nine European airports. The detection performance of the screeners was recorded, and analysed against the identified variables. The study provided scientifically based conclusions about the significance of the bag size variable (by itself and in relation with other variables). The important recommendations from the study allowed the European Commission to make an informed evidence-based decision on the size of bags passengers that are allowed to take on board aircraft. Based on this study, the European Union decided to repeal the enforcement of the limitation of the cabin baggage to IATA size bags by EC Regulation 358/2008 of 22 April 2008. |

COGNITIVE VISION SYSTEMS (COGVIS)
Description |
The CogVis consortium has been brought together to study the design of Cognitive Vision Systems. In this context a “cognitive vision system” is defined as a system that uses visual information to achieve:
Cognitive vision only makes sense in the context of a “system” where there is a user that provides task information and which uses the information generated by the system. In addition a fundamental assumption is that such systems are embodied so that they interact with the world using active vision, manipulation or similar facilities. |

Aviation Security Systems: Unpredictability Measures Evaluation (ASSUME)
Description
Aviation security measures tend to be predictable, especially for insiders. This can produce severe vulnerabilities in the security level making it potentially easier to circumvent the measures. A project headed by Zurich State Police, Airport Division, was conceived in collaboration with CASRA and the Federal Institute of Technology Zurich (ETHZ) to address this aspect. Within it, basic and applied research is conducted on the impact and mechanisms of unpredictable measures in aviation security on risk perception and risky behavior. A long-term reduction of insider threat is sought through the evaluation and optimization of existing security measures. A central contribution of CASRA to the project is intelligence research and development.

COMPUTER-BASED TESTS FOR CERTIFICATION OF AVIATION SECURITY SCREENERS IN SWITZERLAND
Description
Certification and competency assessment of airport security screeners have become very important topics in the last few years. A common certification procedure helps to achieve comparable standards across different airports and countries. On behalf of this project computer-based tests are used to measure ability and competency of airport security screeners in six Swiss airports. The Object Recognition Test (ORT) is used to assess screener ability needed for recognizing threat items in rotation, when they are superimposed by other objects and placed in close-packed bags. The X-Ray Competency Assessment Test (X-Ray CAT) is used to assess visual knowledge about prohibited items. A theoretical exam on computer (TEC) is applied to test the theoretical knowledge required in airport security screening procedures. The results provide a solid basis for a reliable and standardized certification procedure performed by the Swiss airports in collaboration with the Swiss Federal Office of Civil Aviation (FOCA).

2D VS. 3D X-RAY IMAGE DISPLAY STUDY
Description
While currently state-of-the-art X-ray machines employed at airports for hold baggage screening display static 2D single or multi-view X-ray images, new developments in X-ray screening technology offer 3D rotatable X-ray images, allowing screeners to view a bag from different angles. The purpose of this study is to evaluate this new technology and its effects on the screeners’ detection performance in hold baggage screening (HBS). More specifically, it is investigated if threat detection performance differs significantly between screeners when they analyze X-ray images in single view 2D vs. 3D rotatable X-ray images. If detection performance is significantly better when images are analysed in 3D compared to 2D single view, results imply that viewing baggage with 3D rotatable images provides a significant benefit to the screeners. Furthermore, the results of the project shall give an indication on how screeners who will work with 3D rotatable images for the first time are able to adapt to this compared to screeners who are already experienced in analysing 3D rotatable images. The project is being conducted by CASRA in collaboration with the German Federal Police.

TESTING THE INFLUENCE OF MOTION IMAGING FOR THE INSPECTION OF LAPTOPS IN CABIN BAGGAGE SCREENING
Description
Large amounts of money are being invested into the improvement and further development of new screening technologies, continuously aiming at improving image quality, automatic explosive detection and enhancing the detection of prohibited items for human operators i.e. screening officers. Especially the latter is of high importance, as the actual identification of prohibited items lies mainly in the hands of human operators. Thus, it is of great important to evaluate any new technologies and machines developed for screening purposes with regard to image quality and the actual benefits for the people that have to handle and work with these machines (i.e. man-machine-interaction). The aim of this project was to compare motion imaging (Array CT machine) to single view imaging with regard to detection performance. More specifically, it was investigated whether a significant difference in detection performance aroused when motion imaging was used and laptops were left inside passenger bags compared to the situation where only single view images were provided but laptops were taken out of passenger bags.

ECAC BDS TESTING OF L-3 PROVISION 100 (MIKS)
Description
In state-of-the art airport security screening, passengers have to walk through a metal detector before being allowed to board an aircraft. With bodyscanner technology it is possible since recently to screen passengers more accurately to examine whether they carry prohibited items on the body. The Technical Task Force of the European Civil Aviation Conference (ECAC) has created a Body Scanners Study Group (ECAC BSSG) in 2007. In a two years project, this group has developed a Body Scanner Testing Methodology (BSTM). The main aim of the BSTM is to test human-machine performance using body scanners for the detection of prohibited items carried by passengers. In this project, the BSTM was applied to test the L-3 ProVision 100 body scanner. This project was conducted to apply the BSTM (this was the first time world wide) and to refine the BSTM. The result of this project provided important information for using the BSTM for certification of body scanners in EU and ECAC member states.

STUDY ON THE IMPACT OF DUAL VIEW AND AUTOMATIC EXPLOSIVES DETECTION IN HAND LUGGAGE SCREENING OF LAPTOPS
Description
This study investigated the impact dual view and automatic explosives detection technology have on the performance of aviation security screeners who visually inspect hand luggage using X-ray screening systems. So-called “advanced cabin baggage X-ray screening” (ACBX) systems provide multiple X-ray views of bags and automated explosive detection. A recent study by von Bastian, Schwaninger and Michel (2008) has shown that multi-view X-ray technology can generate key benefits for the screening of hand luggage. One aspect of specific interest in the present study was whether or not it will be possible to leave laptops in a passenger’s hand luggage or whether laptops will continue having to be removed from hand luggage and be screened separately. It was found that ACBX systems have advantages under certain specific conditions, e.g. for the detection of rotated guns. However, leaving laptops in passenger bags cannot be recommended, even if ACBX technology is used. The results of the study have a substantial impact on aviation security regulations in Germany and other European member states.

IDENTITY VERIFICATION FROM PHOTOGRAPHS IN TRAVEL DOCUMENTS: MEASURES OF PERFORMANCE ENHANCEMENT
Description
At border control, it is the security personnel’s job to identify possible passport fraud, in particular to verify whether the photograph in a travel document matches its bearer. However, as various studies have shown, identity verification from document photographs is far from accurate. The aim of this project is thus to develop a procedure for security personnel to enhance identity verification performance from document photographs. In three studies, four factors shall be investigated: First, the reduction of time pressure in identity verification; second, the potential benefit of inversion of the document photograph on identity verification; third, the enhancement of sensitivity towards configural information contained in faces through training; and last, enlargement of the document photograph for better identity verification. All four factors are believed to be potentially beneficial on identity verification performance and could well influence standard verification procedures at border control.

STUDY ON THE EFFECT OF CABIN BAG SIZE ON THE EFFECTIVENESS OF SCREENING
Description
The aim of this project was to provide the basis for scientifically based conclusions about the significance of the bag size variable by itself and in relation with other variables. In this research project the effect of a number of variables including bag size, bag complexity, packing density, etc, on screener performance was investigated. For this, a set of X-ray images of cabin bags were captured, and presented in CBT format to screeners across nine European airports. The detection performance of the screeners was recorded, and analysed against the identified variables. The study provided scientifically based conclusions about the significance of the bag size variable (by itself and in relation with other variables). The important recommendations from the study allowed the European Commission to make an informed evidence-based decision on the size of bags passengers that are allowed to take on board aircraft. Based on this study, the European Union decided to repeal the enforcement of the limitation of the cabin baggage to IATA size bags by EC Regulation 358/2008 of 22 April 2008.
