• An ROC curve plots, parametrically as a function of the decision threshold, the rate of “false
positives”(ie impostor attempts accepted) on the x-axis, against the corresponding rate of …

How can scientific progress be measured? How do we know if a pattern recognition
algorithm performs better on average than another one? How much data is needed to claim …

In this chapter, we give an overall perception to biometrics technologies and systems. First,
the background of biometrics is introduced in Section 1.1. After some basic concepts …

Chances are this is not your first exposure to the field of biometric identification. After all, the
first modern biometric device was introduced on a commercial basis over 25 years ago …

Biometrics is an emerging science and technology with fierce competition and
manufacturers continually refining the technology and claiming high accuracy.“High …

Figure 1.2 shows a schematic of how the biometric authentication process works in practice,
using the sensor (ngerprint reader) in a mobile phone. Because of the decision-theoretic …

Biometric recognition, or simply Biometrics, is a rapidly evolving field with applications
ranging from accessing one's computer to gaining entry into a country. Biometric systems …

In the academic literature, the matching accuracy of a biometric system is typically quantified
through measures such as the Receiver Operating Characteristic (ROC) curve and …

Many aspects of biometrics remain far from being settled. This trend report sets out a number
of relevant insights, experiences and developments in that regard. The report is based on …
