There is an elephant in the room: towards a critique on the use of fairness in biometrics

Abstract:
The proliferation of biometric systems in our societies is shaping public debates around its political, social and ethical implications. Yet, whilst concerns towards the racialised use of this technology have been on the rise, the field of biometrics remains unperturbed by these debates. Despite the lack of critical analysis, algorithmic fairness has recently been adopted by biometrics. Different studies have been published to understand and mitigate demographic bias in biometric systems, without analysing the political consequences. In this paper, we offer a critical reading of recent debates about biometric fairness and show its detachment from political debates. Building on previous fairness demonstrations, we prove that biometrics will be always biased. Yet, we claim algorithmic fairness cannot distribute justice in scenarios which are broken or whose intended purpose is to discriminate. By focusing on demographic biases rather than examine how these systems reproduce historical and political injustices, fairness has overshadowed the elephant in the room of biometrics.
