Biometric Person Authentication IS A Multiple Classifier Problem

Several papers have already shown the interest of using multiple classifiers in order to enhance the performance of biometric person authentication systems. In this paper, we would like to argue that the core task of Biometric Person Authentication is actu ...

Performance Generalization in Biometric Authentication Using Joint User-Specific and Sample Bootstraps

Samy Bengio, Norman Hoon Thian Poh

Biometric authentication performance is often depicted by a DET curve. We show that this curve is dependent on the choice of samples available, the demographic composition and the number of users specific to a database. We propose a two-step bootstrap proc ...

Multimodal Biometrics for Identity Documents

Jonas Richiardi, Andrzej Drygajlo

The MBioID initiative has been set up to address the following germane question: What and how biometric technologies could be deployed in identity documents in the foreseeable future? This research effort proposes to look at current and future practices an ...

Using Chimeric Users to Construct Fusion Classifiers in Biometric Authentication Tasks: An Investigation

Samy Bengio, Norman Hoon Thian Poh

Chimeric users have recently been proposed in the field of biometric person authentication as a way to overcome the problem of lack of real multimodal biometric databases as well as an important privacy issue -- the fact that too many biometric modalities ...

Estimating the Confidence Interval of Expected Performance Curve in Biometric Authentication Using Joint Bootstrap

Samy Bengio, Norman Hoon Thian Poh

Evaluating biometric authentication performance is a complex task because the performance depends on the user set size, composition and the choice of samples. We propose to reduce the performance dependency of these three factors by deriving appropriate co ...

Compensating User-Specific Information with User-Independent Information in Biometric Authentication Tasks

Samy Bengio, Norman Hoon Thian Poh

Biometric authentication is a process of verifying an identity claim using a person's behavioral and physiological characteristics. This is in general a binary classification task because a system either accepts or rejects an identity claim. However, a bio ...

EER of Fixed and Trainable Fusion Classifiers: A Theoretical Study with Application to Biometric Authentication Tasks

Samy Bengio, Norman Hoon Thian Poh

Biometric authentication is a process of verifying an identity claim using a person's behavioural and physiological characteristics. Due to the vulnerability of the system to environmental noise and variation caused by the user, fusion of several biometric ...
