Achieving a balance between the benefits of biometrics in border processes and the risk that they may cause harm to fundamental rights will require gathering more data about the problems biometrics collection is meant to address, as well as detailed policy considerations, attendees heard in the European Association for Biometrics' (EAB's) virtual lunch talk this week. Bianca-Ioana Marcu of Vrije Universiteit Brussel (VUB) gave a presentation on'Biometrics, Facial Recognition and the Fundamental Rights of Migrants,' focussing on the EU migration management context, and considering non-technical impacts. Marcu noted a tangle of databases that could be involved in EU migration processes, but focussed on the EURODAC database. Biometrics have been adopted in immigration systems to apply efficiency, trust and reliability to the large numbers of people moving between countries, Marcu points out. Pressures on EU external borders, both from migration volumes and terrorism concerns, have resulted in a move towards "the establishment of a genuine security union," she says, facilitated by EU-wide information systems.
