The future of aviation security will be driven by data informing risk-based decisions and using integrated sensors and devices from multiple providers. It will require open equipment interfaces and common data formats with an oversight mechanism to provide assurance on aspects such as technical standards, certification and liability. Open architecture (OA) allows hardware, software and algorithms from different suppliers to be easily ‘plugged together’. It is defined by Gartner* as: A technology infrastructure with specifications that are public as opposed to proprietary. This includes officially approved standards as well as privately designed architectures, the specifications of which are made public by their designers. Drivers and challenges The general perception is that, in the airport security environment, OA will deliver system flexibility; faster innovation and time to market; and less costly upgrades. The key drivers to achieve these goals are the integration of third party
