ENHANCED FACE SPOOFING DETECTION THROUGH GEOMETRIC TEMPORAL DYNAMIC ANALYSIS

Abstract

Face spoofing, the act of presenting a fake face or biometric feature to deceive authentication systems, poses a significant threat to the security of facial recognition systems. With the proliferation of biometric authentication in various applications, including mobile devices, banking, and surveillance systems, the vulnerability to face spoofing attacks has become a pressing concern. This paper provides a comprehensive review and analysis of face spoofing detection techniques, focusing on both traditional methods and recent advancements. The review begins by outlining the various types of face spoofing attacks, including printed photos, replay attacks, 3D masks, and makeup disguises. Subsequently, it discusses the challenges faced by face spoofing detection systems, such as the high variability in spoofing materials, illumination conditions, and presentation attacks. Traditional techniques, including texture analysis, motion analysis, and color-based methods, are examined, highlighting their strengths and limitations Furthermore, the paper explores recent advancements in face anti-spoofing, including deep learning-based approaches, convolutional neural networks (CNNs), and recurrent neural networks (RNNs). It discusses the effectiveness of these techniques in mitigating the vulnerabilities of conventional methods and their ability to handle complex spoofing attacks with higher accuracy and robustness. Additionally, the review investigates datasets commonly used for training and evaluating face spoofing detection algorithms, emphasizing the importance of diverse and representative datasets for reliable performance assessment. Furthermore, it discusses evaluation metrics, benchmarking protocols, and open challenges in the field to provide insights into future research directions.
