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.

Understanding voice recognition

While there are many different biometrics, using our voice to identify and authenticate is becoming more commonplace. Voice recognition is gaining in popularity because the technology required to input and transmit voices is already in place. Technologies include the telephony infrastructure, along with components such as speakers and microphones that are built into mobile devices.

In this section, we’ll outline voice recognition and the history that shaped the ability to recognize speech, along with an explanation of how our voices are digitized.

First, let’s take a look at what defines voice recognition.

Defining voice recognition

Voice recognition, also called speaker verification, uses a person’s voice to either identify or authenticate into a system. Voice recognition systems are capable of differentiating between individual voices.

There are many things that can influence the way we speak. A person’s...
