Biometric systems encounter variability in data that influence capture, treatment, and u-sage
of a biometric sample. It is imperative to first analyze the data and incorporate this …

Finger image quality assessment is a crucial part of any system where a high biometric
performance and user satisfaction is desired. Several algorithms measuring selected …

A new software-based liveness detection approach using a novel fingerprint
parameterization based on quality related features is proposed. The system is tested on a …

Fingerprint recognition systems are vulnerable to artificial spoof fingerprint attacks, like
molds made of silicone, gelatin or Play-Doh.“Liveness detection”, which is to detect vitality …

One of the open issues in fingerprint verification is the lack of robustness against image-
quality degradation. Poor-quality images result in spurious and missing features, thus …

Cross-view gait recognition authenticates a person using a pair of gait image sequences
with different observation views. View difference causes degradation of gait recognition …

This work reports a vulnerability evaluation of a highly competitive ISO matcher to direct
attacks carried out with fake fingers generated from ISO templates. Experiments are carried …

Biometric-based recognition has been replacing conventional recognition methods in
security systems. Modern electronic devices such as smartphones and online services have …

This paper addresses the problem of efficiently and accurately generating two-vector tests
for crosstalk induced effects, such as pulses, signal speedup and slowdown, in digital …
