Main research findings

The research in this PhD dissertation focuses on investigating user authentication's accuracy, assurance, and security improvements by introducing high-quality samples and the fusion of biometric modalities while considering privacy implications. The research is based on four research questions, which aim to understand the impact of information fusion, the quality of biometric samples, machine learning, and privacy protection aspects on the recognition accuracy of a biometric system. The research is divided into four main areas:

1. A new approach for multi-biometric fusion based on subjective logic is proposed, and its impact on recognition accuracy is evaluated.

2. The quality of biometric samples is analyzed, and its impact on recognition accuracy is studied.

3. The use of machine learning in biometric authentication systems is examined, and its impact on recognition accuracy is assessed.

4. Privacy protection aspects are examined and integrated into a biometric authentication system to enable compliance with GDPR. The findings of this research have been published in reputed journals and conferences and contribute to the field of biometric authentication by significantly increasing the accuracy and reliability of authentication while also addressing privacy concerns.

Ultimately, this work provides a comprehensive approach to improving the security and privacy of biometric authentication systems.
