In the finger-vein authentication, there are two problems in practice. One is that the quality of
the vein image will be reduced under bad environment conditions; the other is the irregular …

Biometric systems consist of devices, algorithms, and procedures used to recognize
individuals or classes of individuals based on their physical or behavioral characteristics …

Biometric and multibiometric science play an important role in human authentication
systems nowadays. Finger vein pattern is one of the most reliable and secure biometrics due …

Multibiometric systems are very applicable in human identification systems nowadays.
However, using different biometrics may need extra acquisition sensors besides algorithm …

Accuracy of a transient simulator is critically dependent on its device models, and device
model evaluation is often a bottleneck in transient simulation performance. This paper …

In recent years, biometric systems for identification purposes have been developed for
different traditional methods like fingerprint, face, iris, retina, voice, signature, hand …

Many researchers estimated the confidence interval of the evaluation index such as FMR
and studied the relationship between the confidence interval width of FMR and sample size …

Biometrics is defined by the International Organization for Standardization (ISO) as “the
automated recognition of individuals based on their behavioral and biological …

Before a biometrics system is implied, we evaluated its performance by testing data. While a
test dataset, instead of the universal dataset, is used, the performance indices cannot be …

This chapter presents an overview of biometric systems, with the goal of providing context for
the technology described in the presented work. The principles of biometric recognition, their …
