Biometrics — the science of using the body to identify a person — is everywhere, not just in science fiction, but in everyday life. Today, biometrics is on the cutting edge of security. It's used for access into banks and airports, as well as to keep money and personal information safe. Methods like fingerprinting and retinal scanning might be more familiar, but biometrics can also identify people based on ear shape, scent, vein pattern and much more. 

This book explores nine biometrics in detail, explaining how each works, where it's used, its pros and cons, and how it compares to other techniques. It also discusses privacy, security, why we need methods of identification and touches on biometrics of the future. Engaging and colourful design and playful illustrations alongside surprising anecdotes, historical context and humour make this an enjoyable, in-depth look at a hot topic. Informational text features include sidebars, diagrams, sources, a glossary and an index. (From OwlKids)

Biometrics won the 2017 Lane Anderson Award for Canadian science writing.

From the book

You are one in a million. Actually, if we include all the people roaming the planet, you're more like one in 7.4 billion. (But who's counting?) There are lots of things that make you stand out from the gigantic human crowd. Your ideas, values and beliefs are an important part of what make you an individual.

Your physical features play a big role in your uniqueness, too. Each day, you're recognized as "you" because of the way you look. And you recognize those who are important in your life just the same way. For instance, when you spot a family member getting out of a car, you know that person immediately based on his or her appearance. And that person knows you just by glancing your way.
