Zoo Graph: a New Visualisation for Biometric System Evaluation

Résumé

Biometric authentication systems suffer from several performance limitations. Many performance metrics exist to assess the overall performance of such systems. However, these metrics provide a quantitative assessment in terms of errors without explaining the reasons behind the set of users who significantly contributed for these errors. Towards contributing to solve this problem, we present a novel method (named Zoo Graph) to visualize the performance of a biometric system as a graph thanks to a database of recognition scores. Our approach is an improvement of the Zoo Plot and emphasizes on the relations between the individuals of the database and allows interactive manipulations to track these relations and understand why the biometric authentication method reacts this way. This graph provides researchers with an additional visual assessment tool that would identify problematic users. Such information would allow researchers to update their developed authentication algorithms to reduce those errors.
