Biometric Authentication in the Face of Spoofing Threats: Detection and Defense Innovations

Abstract

Biometric authentication systems have emerged as a critical method of ensuring secure access control across various domains, from mobile phones to financial transactions. However, the systems are increasingly vulnerable to spoofing attacks, where imposter individuals attempt to deceive the biometric sensors using counterfeit biometrics, like images, 3D prints, or printed fingerprints. Spoofing attack development poses a significant threat to the security and reliability of biometric authentication systems. Current defense mechanisms are typically ineffective in providing real-time detection and adequate protection against sophisticated spoofing attacks. This research aims to fill the large gap in current biometric security systems using research into new detection and defense methods against spoofing attacks. The core focus is on designing advanced algorithms and machine learning models capable of detecting subtle but noticeable artifacts in biometric information that point to manipulation or forgery. Secondly, the research delves into multi-modal biometric systems that combine various biometric modalities (e.g., face recognition, fingerprint, and iris scanning) to enhance spoofing resilience. The research also delves into the integration of explainable AI practices such that detection models not only exhibit high accuracy but also provide interpretable and transparent results. This research aims to enhance the resistance of biometric systems to emerging spoofing methods with the innovations proposed, thereby offering a practical solution to a real problem for existing authentication technology. The results will help to make the security and reliability of biometric identification more robust in many sensitive sectors, including financial institutions, government security, and personal devices.
