Identity Management with Biometrics

By: Lisa Bock

Overview of this book

Biometric technologies provide a variety of robust and convenient methods to securely identify and authenticate an individual. Unlike a password or smart card, biometrics can identify an attribute that is not only unique to an individual, but also eliminates any possibility of duplication. Identity Management with Biometrics is a solid introduction for anyone who wants to explore biometric techniques, such as fingerprint, iris, voice, palm print, and facial recognition. Starting with an overview of biometrics, you’ll learn the various uses and applications of biometrics in fintech, buildings, border control, and many other fields. You’ll understand the characteristics of an optimal biometric system and then review different types of errors and discover the benefits of multi-factor authentication. You’ll also get to grips with analyzing a biometric system for usability and accuracy and understand the process of implementation, testing, and deployment, along with addressing privacy concerns. The book outlines the importance of protecting biometric data by using encryption and shows you which factors to consider and how to analyze them before investing in biometric technologies. By the end of this book, you’ll be well-versed with a variety of recognition processes and be able to make the right decisions when implementing biometric technologies.

Fine-tuning the decision process

When thinking about a biometric identifier, we know that it represents some human attribute. Because we are dealing with human attributes, there are times we must make some adjustments to the system so that the system returns an acceptable result.

In this section, we’ll see why there may be a need to upgrade the template on file because of significant changes to the client’s biometric identifier. We’ll also see how human intervention might be required during the matching process, as well as how we can tune the acceptance threshold. In addition, to always get the most accurate results, we’ll see why it’s important to prevent spoofing.

First, we’ll take a look at examining the client’s template.

Upgrading the template

A biometric system, like any other system, must be upgraded and maintained. In addition to the system, we must take the users into account. Over time, the system may not be able...
