APSS Software & Services Ltd is part of the Center for Adaptive Security Research and Applications (CASRA), which was founded in 2008. CASRA emerged from the Visual Cognition Research Group of the University of Zurich, which was founded by Adrian Schwaninger in 1999. Today, CASRA APSS has a workforce of around 30 people (full time equivalent: 22), comprising of psychologists, economists, computer scientists, imaging specialists, software developers, aviation security experts, and more, most of which have an academic degree.
The main objective of CASRA is to increase security and facilitation at airports and other environments involving people and technology.

  • CASRA uses an adaptive approach by combining applied psychology, computer science and economic analysis.
  • All software, methods and procedures are based on scientific research and are continuously improved in close collaboration with experts and end users.
  • Our knowledge is provided to society through publications in scientific journals, conferences and magazines.

Studies in the areas of aviation security, human factors, human-machine interaction, cognitive and computational modelling, perception and recognition of objects have led to the development of applications for training and testing in the area of aviation and border security, installed in more than 40 countries at more than 900 airports and other sites in Europe and worldwide.

CASRA uses its experience in various fields to support various aspects of TRESSPASS


CASRA will use its experience in order to support activities related to the conceptual groundwork in WP1. We support the end-user requirement definition, the development of a risk-based border management concept, and the development of a legal and regulatory framework using our expertise in this kind of activity in aviation security and border control. By bringing our designing capabilities to the table, we support WP2. We strongly support WP4’s web intelligence activities, based on our knowledge and activities in another multi-year project called Systematic Threat Assessment. This methodology is the basis for our red teaming activities, with which a specialized team are penetration testing the newly developed risk-based concepts by trying to manipulate sensor or other data. The findings are fed back to strengthen the concepts and resilience thereof. Our knowledge in human-machine interaction, and specifically the usability of graphical user-interfaces, supports the set of applications developed within WP5. CASRA is an expert in developing many different forms of training which aims at helping human operators in the best possible way to incorporate new knowledge and processes. This is used in WP7 to organize and develop a training to provide training for the risk-based border concepts (border guards and C2-operators). Our experience of conducting scientific pilots will be provided in WP8 – Pilots.
