  • The technopolitics of database interoperability

    Open Access•Rocco Bellanova, Jan-Hendrik Passoth et al.•ARTICLE•Big Data & Society•2026

    We need to talk about the technopolitics of database interoperability. To date, databases remain crucial to datafied forms of public security, migration and border control. How databases are to speak to each other has cascading effects on the relation between power and knowledge, and upon how digital data, rights and subjectivities meet. This is especially the case in domains at the core of statecraft, where database interoperability affects both…

  • Devices of suspicion. An analysis of Frontex screening materials at the registration and identification center in Moria

    Open Access•Silvan Pollozek, Jan-Hendrik Passoth•ARTICLE•New Community•2024•Cited by: 5•References: 41

    The identification of migrants and the creation of data identities lies at the core of datafied forms of migration and border control. In recent years, Frontex has made identification to one of its key tasks and conducted so-called screenings in many EU member states. Yet only little is known about the screening materials in use. Based on an ethnographic inquiry of Frontex' data practices, this paper analyses Frontex booklets, dossiers, questionn…

  • Provisional by design. Frontex data infrastructures and the Europeanization of migration and border control

    Silvan Pollozek, Jan-Hendrik Passoth•ARTICLE•Science as Culture•2023•Cited by: 3•References: 20

    Data infrastructures for the Frontex joint operations are often only temporary and thus in need of being built up and removed easily, adjustable to changing constellations of security actors, and adaptable to new situations. They need to work through flaws, gaps, and inconsistencies. Still, they fabricate data used for the re-identification of migrants, police investigations, situational pictures, or risk analysis and lead to the intensification …

  • Not so fast! Data temporalities in law enforcement and border control

    Open Access•Matthias Leese, Silvan Pollozek•ARTICLE•Big Data & Society•2023•Cited by: 3•References: 43

    In this paper, we investigate the temporal implications of data in law enforcement and border control. We start from the assumption that the velocity of knowledge and action is defined by heterogeneous formations and interactions of various actors, sites, and materials. To analyze these formations and interactions, we introduce and unpack the concept of "data temporality." Data temporality explicates how the speed of knowledge and action in dataf…

  • Mapping European Border Control

    Open Access•Silvan Pollozek•ARTICLE•Social Inclusion•2020•Cited by: 4•References: 14

    The so-called hotspots—identification and registration centres on the Aegean Islands in Greece and in Italy—are not only sites of remote detention, European intervention or differential inclusion, but also logistical set-ups, where data is generated and spread across state institutions. Such socio-technical assemblages are hard to research not only because of state actors’ desire to keep things secret but also because of methodological issues. Ho…

  • Turbulences of speeding up data circulation. Frontex and its crooked temporalities of 'real-time' border control

    Open Access•Silvan Pollozek•ARTICLE•Mobilities•2020•Cited by: 9•References: 23

    In the last decade, various information systems have been created to process data in ‘near to real-time’ across agencies to ‘improve situational awareness and to increase reaction capability’ at the external borders of the European Union. While the policing of mobilities is increasingly discussed in terms of instantaneity, speed, and real-timeness, little has been said about the temporalities of data mobility. This paper focuses on the socio-tech…

  • Infrastructuring European migration and border control

    Open Access•Silvan Pollozek, Jan Hendrik Passoth et al.•ARTICLE•Environment and Planning D…•2019•Cited by: 53•References: 33

    This paper examines Moria hotspot in Greece as a logistical site which fulfills two different functions within the European migration and border regime. It locates, contains, and sorts individuals locally at the external borders of the EU and creates, inserts, and processes data for controlling people on the move. Based on ethnographic fieldwork in Greece, including interviews with local administrators from the Registration and Identification Ser…
