Biometrics

Background:

Vital signs, including electroencephalogram (EEG) signals, are increasingly used in expert systems and biometrics.
Motor tasks, whether performed or imagined, significantly alter brain wave patterns and EEG signal characteristics.
Exploring EEG biometrics from a cross-task perspective is crucial for robust identification systems.

Purpose of the Study:

To develop a novel method for biometric verification using EEG signals, specifically addressing the challenges posed by different motor tasks.
To create a deep EEG signal descriptor capable of assessing the impact of motor tasks on biometric accuracy.
To evaluate the proposed method's performance using a comprehensive dataset and rigorous evaluation protocol.

Main Methods:

A deep learning approach combining Convolutional Neural Networks (CNNs) and Squeeze-and-Excitation Blocks was developed.
A data augmentation technique was employed to address the limited data volume for training deep CNN models.
An evaluation protocol was designed to assess robustness concerning the number of EEG channels and ensure non-overlapping train/test sets.

Main Results:

The novel method achieved a new state-of-the-art Equal Error Rate (EER) of 0.1% in the cross-task biometric verification scenario.
Squeeze-and-Excitation-based networks demonstrated superior performance compared to simple CNN architectures in three out of four cross-individual scenarios.
The proposed data augmentation technique improved the overall performance of the deep CNN model.

Conclusions:

The developed deep EEG signal descriptor effectively assesses the impact of motor tasks on biometric verification.
The Squeeze-and-Excitation enhanced CNN approach offers a robust solution for cross-task EEG-based biometrics.
This research advances the field of EEG biometrics, demonstrating high accuracy and robustness in identifying individuals across varying tasks.
