METICOS aims to introduce Big Data Analysis of border control information systems, in order to provide a step-change towards more modern and efficient Smart Border management and towards gaining societal and political acceptance of modern control technologies of EU borders such as “no gate solutions”. It is therefore positioned as an initiative to create a real-time decision-support system with regard to different Smart Border control technologies that empowers two major stakeholder groups within the European border control sector (i.e., travellers and border control authorities & service providers) to ensure user acceptance, secure positive societal impact and maximize border control process efficiency. To this end, the METICOS project will develop a platform that integrates information systems and networks of data sources in order to validate the efficiency and users acceptance of border control technologies. The proposed platform will provide metrics and KPIs to authorities and decision makers, based on a number of independent variables: performance expectancy, effort expectancy, facilitating conditions, physical privacy, accuracy, information privacy, ethical and societal perceptions. To maximize impact of the project, METICOS will join the European Initiative for Smart Borders and contribute aforementioned cross-border and cross-cultural Big Data Analysis and decision support systems that feature harvesting of multi-lingual and cross-sectorial data from heterogeneous sources, different analytics approaches and risk assessment methods. METICOS will be demonstrated and validated under real operating conditions. This will involve two pilot implementations executed at five different countries involving real travellers and staff. Furthermore, the METICOS ecosystem aims to work closely with border control research initiatives to demonstrate its operational performance improvements by means of combined validation with these solutions.
