Several studies have shown the existence of biometric zoos. The premise is that in biometric systems people fall into distinct categories, labeled with animal names, indi- cating recognition difficulty. Different combinations of ex- cessive false accepts or rejects correspond to labels such as: Goat, Lamb, Wolf, etc.

Aug 1, 2019 · Doddington zoo is a biometric menagerie that defines and labels user groups with animal species to reflect their behavior with the biometric systems. This menagerie was developed for different biometric modalities including keystroke dynamics.

The zoo-plot analysis, developed by Yager and Dunstone (2011), extends George Doddington’s(1998) original classification of the biometric menagerie. New animals are introduced: 1. Doves they produce high match scores against their speaker model and low match scores against the imposter models.

The biometric zoo menagerie was developed to address the impact of individuals on performance of a biometric system, although Tabassi [1] concentrated on the image as opposed to the individual. There are three main types of zoo classifications:

Abstract— Recent research in biometrics has suggested the existence of the “Biometric Menagerie” in which weak users contribute disproportionately to the error rate (FAR and FRR) of a biometric system. The aim of this work is to utilize this ob-servation to design a multibiometric system where information is consolidated on a user-specific basis.

We establish formal definitions for these animals and a statistical test for their existence. A thorough investigation is conducted using a broad range of biometric modalities, including 2D and 3D faces, fingerprints, iris, speech, and keystroke dynamics.

This work investigates biometric zoos generalization across algorithms and data sets. For example, if a subject is a Goat for algorithm A on data set X, is that subject also a Goat for algorithm B on data set Y? This paper introduces a theoretical framework for …
