Interactive quality-driven feedback for biometric systems

The application of biometric technology has so far been top-down, driven by governments and law enforcement agencies. The low demand of this technology from the public, despite its many advantages compared to the traditional means of authentication is probably due to the lack of human factor considerations in the design process. In this work, we propose a guideline to design an interactive quality-driven feedback mechanism. The mechanism aims to improve the quality of biométrie samples during the acquisition process by putting in place objective assessment of the quality and feeding this information back to the user instantaneously, thus eliminating subjective quality judgement by the user. We illustrate the feasibility of the design methodology using face recognition as a case study. Preliminary results show that the methodology can potentially increase efficiency, effectiveness and accessibility of a biométrie system.
