Area of Science:

Biometrics
Cybersecurity
Machine Learning

Background:

Multibiometric systems are vulnerable to presentation attacks.
Existing models overestimate vulnerability by assuming fake scores match genuine scores.
This leads to ineffective fusion rules and security overestimation.

Purpose of the Study:

To propose a statistical meta-model for face and fingerprint presentation attacks.
To characterize a wider range of fake score distributions, including unknown attacks.
To enable thorough security evaluation and uncertainty analysis of multibiometric systems.

Main Methods:

Developed a statistical meta-model for presentation attacks.
Incorporated uncertainty analysis for vulnerability assessment.
Designed secure fusion rules based on the proposed model.

Main Results:

The model reliably predicts multibiometric system performance against known and novel attacks.
Fusion rules designed with the model show improved performance trade-offs under attack.
The approach quantifies vulnerability variations against diverse attack types.

Conclusions:

The proposed meta-model enhances the security evaluation of multibiometric systems against presentation attacks.
It allows for the design of more robust fusion rules, improving overall system security.
The method shows potential for extension to other biometric modalities.
