Facial Recognition in the Field of Security

This paper focuses on facial recognition systems (FRSs) in the security field. FRSs capture biometric data and process it to compare it with existing data stored in databases. In security practice, FRSs are used to scan people, e.g. in crowds or during large events, and check whether their biometric features match with data, of the same kind, of persons suspected of terrorism or other serious crimes. A comparative overview shows that many countries are using, or at least trialling, these systems.
Against this background, some concerns arising from a public law perspective are examined, i.e.: 1) whether the principle of non-discrimination is respected by FRSs; 2) to what extent the principle of transparent decision-making is fulfilled; 3) whether and how privacy rights are guaranteed.
The research claims that the abovementioned safeguards are often violated and points out the need for a thoughtful and comprehensive supranational framework regulating FRSs, which is lacking at present.
