Abstract : Smart borders, intelligent systems of filtering travelers by detecting suspects of crime and
terrorism through interoperable national data bases and regional agreements are
proliferating. In the European Union it began with the Schengen Information System. SIS-VISEURODAC,
EES, ETIAS, ECRIS are acronyms for different realizations and projects of Entry and
Exit Systems, of pre-frontiers zone, of policy checks regarding police, immigration and
asylum, tracing people and scoring the degree to which they can be suspected to be illegal
or criminal. Security stakes have been technologized. This is a profound reconfiguration of
the different regional fields of security professionals with the emergence of a transnational
guild regrouping data analysts, civil engineers on IT systems and border controls, changing
de facto who is deciding the limits between security and insecurity, risk and fate. This
importance of the online -virtual regarding the off-line- actual is affecting freedom and
criminal justice.
