Cross-Database Liveness Detection: Insights from Comparative Biometric Analysis
International Workshop on Social Communication and Information Activity in Digital Humanities(2024)
摘要
In an era where biometric security serves as a keystone of modern identity
verification systems, ensuring the authenticity of these biometric samples is
paramount. Liveness detection, the capability to differentiate between genuine
and spoofed biometric samples, stands at the forefront of this challenge. This
research presents a comprehensive evaluation of liveness detection models, with
a particular focus on their performance in cross-database scenarios, a test
paradigm notorious for its complexity and real-world relevance. Our study
commenced by meticulously assessing models on individual datasets, revealing
the nuances in their performance metrics. Delving into metrics such as the Half
Total Error Rate, False Acceptance Rate, and False Rejection Rate, we unearthed
invaluable insights into the models' strengths and weaknesses. Crucially, our
exploration of cross-database testing provided a unique perspective,
highlighting the chasm between training on one dataset and deploying on
another. Comparative analysis with extant methodologies, ranging from
convolutional networks to more intricate strategies, enriched our understanding
of the current landscape. The variance in performance, even among
state-of-the-art models, underscored the inherent challenges in this domain. In
essence, this paper serves as both a repository of findings and a clarion call
for more nuanced, data-diverse, and adaptable approaches in biometric liveness
detection. In the dynamic dance between authenticity and deception, our work
offers a blueprint for navigating the evolving rhythms of biometric security.
