Due to the geopolitical situation, the scarcity of raw materials, the foreign policy actions of the major powers, the excessive use of resources worldwide and the struggle for them, as well as the inequalities caused by the demographic explosion of developing countries, europe and thus Hungary from the wider Middle East region have been under considerable migratory pressure for a long time, and this has increased further in 2021 on the basis of statistical data. (Frontex). Europe is trying to provide more answers to the problem. It is trying to keep refugees as far away as possible by developing and improving living conditions in the countries where migration flows originate, as well as by establishing migration zones beyond the EU’s borders and financing them, because these problems need to start to be addressed and solved at local level. Despite all this, refugees are constantly reaching Europe, and unfortunately among them are not only those who fear for their lives and lose everything, fleeing war, but also economic migrants who join the wave of migration and are probably members of organisations that pose a threat to European values and public security. (Kotzur, Moya, Sözen, Romano 2020). By building physical border closures, several EU countries have closed certain migration routes, but this has not eliminated the problem, only the routes have been reorthled. The registration and clear identification of immigrants in the attempt to cross the border and their identification within the EU pose a number of unresolved problems for the authorities. (Beňuška, T., Nečas, 2021). We are reviewing and comparing the methods of identification used in border policing with modern biometric identification methods in order to draw attention to the fact that technology has long been ready to be used to protect our security in the service of European values and security. But at the same time, a significant deterrent is the difficult transition from entrenched solutions to the fear of misuse of biometric data. In order to achieve this, it is necessary to consider trade-offs in use and technology and to think more effectively together at EU level as a common solution on the regulatory side. (EU Regulation 399/2016).
