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.

Learning the structure of the eye

Concurrent to understanding the concept of iris recognition, we’ll want to take a minute to study the eye itself. We’ll also want to take a look at some diseases and aging factors that can alter the effectiveness of obtaining an acceptable iris image.

Let’s start with an overview of the most common eye elements.

Viewing the major elements of the eye

The human eye is in a family called Camera Eyes. It is referenced as such because a camera has a lens that opens during image capture to allow light to pass through and enter the camera. Similar to a camera, the pupil regulates the amount of light that enters the eye.

As shown in the following screenshot, we see the major structures of the eye. The iris is the colored portion in the front of the eye, the pupil is in the center of the iris, and the retina is at the back of the eye:
