All about that BASE: Modeling Biometric Authentication Systems and their Evaluations to enable a more efficient Exchange of Research Results

If a researcher wants to contribute in the field of biometric authentication systems (BAS), much manual work is required to gather the current state-of-research (SoR) for a specific type of BAS. Due to loosely structured scientific papers as result reports, all relevant details need to be extracted, aggregated and collected individually. Once the SoR is determined, an exchange with other researchers is hardly possible due to a missing exchange format and they usually have to start from scratch repeating the same inefficient procedure often targeting the same papers. This work presents a domain model for biometric authentication systems and their evaluations, BASE, as a solution. It models and interconnects biometric characteristics, the target architecture, evaluation scenarios, and evaluation criteria grants to represent the most common parts of a BAS. For evaluation, we map 12 BAS approaches from related work into BASE and determine mainly low mapping efforts. In this context, we first identified diverse subsets of BASE being inferable from the analyzed papers. Secondly, most researchers still target rather broad evaluation categories like security or usability instead specific criteria within these categories where the latter would simplify the basic assessment of a BAS. Overall, we consider BASE a promising step to improve the efficiency in SoR determination.
