September, 2024: Publication on remote versus local cabin baggage screening

Members of CASRA recently published a study in the International Journal of Industrial Ergonomics on remote cabin baggage screening (RCBS) versus traditional screening at the lane, i.e. local cabin baggage screening (LCBS). The study used linear mixed models for analyzing threat image projection (TIP) data from 1706 screeners collected over two years (669’168 TIP events). The results showed better detection of prohibited articles (higher hit rate) and longer processing times in RCBS than in LCBS. In both settings, we found a decrease in the hit rate with increasing time on task, and this decrease was stronger when the task load was high. Interestingly, the effects of work setting, time on task, and task load were relatively small compared with the interindividual differences in performance across screeners. The published paper is available here.

SHOULD SECURITY OFFICERS BE LIMITED TO 20 MINUTES OF X-RAY IMAGE SCREENING?

European regulation currently restricts the inspection of X-ray or CT images of cabin baggage to 20 minutes of continuous screening. To evaluate whether this duration could be increased, a group of security officers working in remote cabin baggage screening was inspecting images for up to one hour. Results suggest that 30-40 minutes of image inspection seem feasible if security officers can stop early when their concentration wanes.

X-RAY SCREENING OF HOLD BAGGAGE: WHAT VISUAL-COGNITIVE ABILITIES ARE NEEDED FOR 2D AND 3D IMAGING?

The task of an airport security officer is to visually inspect X-ray images of luggage and take a decision within sec­onds whether it is a harmful piece of baggage or not. While still many airports conduct security screening with 2D multi-view X-ray imaging technology, newer technol­ogy is based on 3D CT imaging and brings along new features such as 360° rotation and slicing through the bag. Important to know is: “Are the same visual-cognitive abilities needed for 3D CT image inspections?” This ar­ticle describes results from a first study and what these results imply for future personnel selection.

AIRPORT SECURITY X-RAY SCREENING OF HOLD BAGGAGE: 2D VERSUS 3D IMAGING

At airports worldwide, hold baggage is screened using X-ray machines with automated explosive detection. Older systems are based on 2D multi-view X-ray (2D imaging) whereas newer systems are based on computer tomography (CT) that features 3D rotatable images (3D imaging). We compared the visual inspection performance of screeners using 2D imaging versus 3D imaging. Results showed that despite lower image quality of 3D imaging, screeners achieved a similar detection performance with 3D imaging to that for 2D imaging. Screeners required more time for visual inspection of 3D versus 2D images. However, due to lower false alarm rates of 3D imaging systems compared to 2D imaging systems, baggage throughput is still much higher when using 3D imaging in hold baggage screening.

We live in a fast-moving world in which vast amounts of data are produced at an accelerating pace. A systematic analysis of data from the open and deep web allows identifying new and emerging threats against civil aviation at an early stage. With the Systematic Threat Assessment (STA), we monitor large amounts of data in open source media and the deep web using different methods for search, data ingestion, and analysis by applying machine learning algorithms. This allows early threat identification to define immediate countermeasures such as updates to recurrent training for keeping screeners up to date regarding new and emerging threats. In this article, we explain our STA process and countermeasures using concrete examples.

SINGLE-VIEW, MULTI-VIEW AND 3D IMAGING FOR BAGGAGE SCREENING: WHAT SHOULD BE CONSIDERED FOR EFFECTIVE TRAINING?

X-ray screening of passenger baggage is conducted at airports worldwide to prevent terrorist attacks and other acts of unlawful interference against civil aviation. The best equipment is of limited value if the humans who operate it are not trained appropriately. But what should be considered for effective training when single-view, multi-view or 3D imaging is used for cabin baggage screening? This article provides recommendations based on scientific studies conducted with screeners over the last 15 years.

SESSION DURATION OF THE X-RAY SCREENING TASK UP FOR DEBATE

“Persons screening cabin baggage by X-ray or EDS equipment shall normally not spend more than 20 minutes continuously reviewing images. After each of these periods, the screener shall not review images for at least ten minutes.” This is mandated by the European Commission implementing Regulation (EU) 2015/1998. To be compliant, screeners working at airport security checkpoints have to change from X-ray screening to another position after 20 minutes. In remote screening, such rotation is operationally more difficult and compliance with the strict tenminute break can be challenging. Therefore, an interest in considering longer X-ray screening durations exists. CASRA has conducted a study to investigate how detection performance changes during 60 minutes of consecutive X-ray screening and what role ten-minute breaks play.

TIP DATA ANALYSIS MADE EASY WITH THE CASRA TIP DATA TOOL

Threat Image Projection (TIP) is a technology of current X-ray machines that allows exposing screeners to fictional but realistic X-ray images during the routine baggage X-ray screening operation. TIP is used for several purposes, e.g. to keep security screeners’ motivation and attention at a high level. However, the analysis of a large amount of TIP data by hand is complicated, error-prone and time-consuming. Hence, TIP data analysis could benefit from an automated process. To this end, we developed the CASRA TIP Data Tool, which is integrated into the CASRA Solution, as a means to facilitate the aggregation and to analyze large amounts of TIP data in an efficient and user-friendly, easy-to-use way. Results are presented in detailed and standardized reports. These reports include TIP performances of security personnel, hit rates, non-TIP alarm rates and the number of TIP images shown. Thus, the TIP Data Tool ensures the compliance with the EU’s legal requirements with minimum expenditure of time.

CENTRALIZED IMAGE PROCESSING AT CHECKPOINT SECURITY – IMPACTS OF VARIOUS IMPLEMENTATION POSSIBILITIES

Remote screening of hold baggage based on centralized image processing (CIP) has been in use since the beginning of this century and is the common practice at larger airports. Remote screening of cabin baggage, however, is relatively new, with first projects having started around eight years ago. Introducing CIP at security checkpoints has the potential to dramatically increase an airport’s capacity and the efficiency of passenger screening and is therefore a valuable option to tackle the increasing air passenger traffic numbers, which according to IATA , are forecasted to double by 2035. An analysis conducted by CAS RA of previous experiences by pioneers and early adopters of CIP for checkpoint security has shown that a well-planned and thoroughly evaluated CIP implementation is critical for success. This article will give an introduction and overview of CIP, discuss the potential benefits and pitfalls to look out for and compare different CIP implementation possibilities regarding effectiveness, efficiency and human factors.

X-RAY IMAGE QUALITY AND THE USEFULNESS OF IMAGE ENHANCEMENT FUNCTIONS

The importance of X-ray image quality and image enhancement functions for the visual inspection of passenger bags has been investigated and discussed in different scientific studies, mainly for airport security screening. Also for other domains, such as security screening at critical infrastructures, it is assumed that a good X-ray image quality and the availability of different image enhancement functions are important for screeners to achieve good performance in detecting prohibited items. Therefore, Smiths Detection asked CAS RA to investigate the usefulness of an optimized default image and of the further developed image enhancement functions for the new X-ray machine HI-SCAN 6040C in a scientific study. In addition, the question of how security officers (operators) perceive an optimized background contrast, which is available on that machine, was addressed. Finally, relevant aspects such as how operators normally proceed when analyzing X-ray images, which image enhancement functions are used and how often, were explored.

INTERDICTING SMALL ARMS IN POSTAL SHIPMENTS (ISAPS)

Latin America and the Caribbean have, in general terms, experienced a dramatic increase in armed violence in recent years, driven in large part by the illicit trafficking of firearms, its parts/components, and ammunition. Public policies against illicit arms trafficking in Latin America and the Caribbean have led toan increased use of X-ray technology for the screening of postal shipments. Thus, states have called on the United Nations Regional Centre for Peace, Disarmament and Development in Latin America and the Caribbean (UNLIREC) to provide specialized interdiction tools and X-ray screening training to help combat illicit arms trade by developing a Course for Interdicting Small Arms in Postal Shipments (ISA PS). The project’s main goal is to boost the capacity of Latin American and Caribbean states to reduce the distribution of illicit arms and their parts/components via postal shipments. Crucial milestones of the project were the development of an Arms, Ammunition, Parts and Components Identification Guide in collaboration between UNLIREC and CAS RA, and a pilot course and study in Costa Rica.

HOW USEFUL ARE ASSIS TED TARGET RECOGNITION ALGORITHMS AND TRAINING FOR IMPROVING THE DETECTION PERFORMANCE OF CUSTOMS OFFICERS?

In the CAS RA Newsletter one year ago (Issue 12, March 2016), we have described AC XIS (Automated Comparison of X-ray Images for Cargo Scanning). This is a research project funded by the European Union under the 7th framework program with the main aim to increase effectiveness and efficiency of cargo screening at customs. Among other tasks, the project researched and developed assisted target recognition (AT R) algorithms to assist customs officers in the challenging search for illicit goods in cargo containers. With the final decision of whether a container should be opened for further investigation still in the responsibility of the officers, the detection performance of the AT Rs is not the only determinant of their benefit. Also the successful interaction between the officers and the AT Rs is crucial for the joint performance. This joint performance was investigated in a validation study, also considering the importance of training for detection performance.

IS EVERYDAY OBJECT KNOWLEDGE RELATED TO XRAY SCREENERS’ EFFECTIVENESS AND EFFICIENCY?

The main objective of CAS RA is to increase security and facilitation at airports and other environments involving people and technology, using an adaptive approach by combining applied psychology and computer science. Learning which objects are prohibited and what they look like in X-ray images of passenger bags is important for X-ray screeners to achieve a good detection in visual inspection of passenger bags. However, as these bags also contain a large variety of harmless everyday objects, it could be assumed that knowing how such objects look like in X-ray images might help screeners to work better. CAS RA researchers conducted a scientific study to investigate whether the knowledge of everyday objects is related to X-ray screeners’ effectiveness and efficiency (Experiment 1) and if novices’ everyday object knowledge can be trained (Experiment 2).

EMOTIONAL EXHAUSTION, JOB SATISFACTION AND WORK − FAMILY CONFLICT IN AIRPORT SECURITY OFFICERS

Situational factors such as task sequence, work environment and team interactions have proven to affect the performance of airport security officers. However, previous research has not focused on the relationship between specific work characteristics and other factors, such as emotional exhaustion. A recently published study has addressed this gap by examining the effects of work-family conflict as intervening variable in the job demands resources model between workload, supervisor support, emotional exhaustion and job satisfaction in 1’127 airport security officers at a European airport.

CASRA E-LEARNING MODULES FOR KEEPING AIRPORT SECURITY OFFICERS UP-TO-DATE REGARDING CURRENT, NEW AND EMERGING THREATS

Computer-based training is a widely used effective and efficient tool to achieve and maintain high levels of detection of prohibited items in X-ray images by airport security officers. For certain current, new and emerging threats, screeners may also benefit from conceptual and contextual knowledge, e.g. on current trends to hide improvised explosive devices in passenger bags. E-learning modules that combine images, textual content and interposed questions can be a valuable addition to X-ray image interpretation training. In this article, we explain important scientific principles and show examples of how to use this training method.

XP-DITE – INTRODUCING A SYSTEM LEVEL APPROACH TO EVALUATING AIRPORT SECURITY CHECKPOINTS

Security checkpoints pose central elements at airports across the world today. Their design, technical equipment, and processes determine security, throughput, and passenger satisfaction. However, as of today, airport security checkpoints are neither developed, nor evaluated in a holistic manner. Equipment and staff are extensively tested and certified, but the performance of the system as a whole is rarely taken into account from the start, nor is it consistently evaluated. The EU FP7 project XP-DITE aims at changing this.

APPROACHING SECURITY FROM ANOTHER ANGLE – BEHAVIORAL SECURITY SCREENING

Security screening processes at airports are still mainly focused on finding prohibited items. However, a growing number of authorities worldwide are interested in security measures at airports that also focus their attention on malicious intent: Trained personnel are scanning travelers for suspicious behavioral cues to identify wrongdoers. However, the question what form such a behavioral security screening (BSS) program should take or how it should be implemented is still in an investigation phase. CASRA conducted an 18-months scoping study, leading to the recommendation of a six-step process to BSS program implementation.
