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.

Measuring an individual’s gait

Gait recognition is a behavioral biometric that identifies the manner and style of how we walk. Using a gait to identify an individual is an unobtrusive biometric that does not require the cooperation of the individual. In this section, we’ll outline how gait recognition works and how this biometric can aid law enforcement in threat management.

Let’s start with how we define and assess a subject’s gait or stride.

Characterizing a gait

Gait recognition is a unique biometric that measures the various parameters involved when we walk. The gait cycle consists of several iterations of foot-to-surface (or heel strike) contact for the same foot.

Let’s first outline what is measured when assessing our gait.

Measuring our stride

When we walk, we move through various phases, according to the position of our feet and legs. All of these movements can be measured. Phases range from the stance, through the resultant...
