Summary

By now, you have a better understanding of the basics of biometric technology. In addition to providing authentication, we learned that we can also use biometrics to identify an individual. You can now appreciate the rich history of biometrics, from early manual methods to today’s advanced systems. In this chapter, we explored how biometrics can provide a straightforward simple authentication process. You then learned how biometric technologies are ideal in many different applications and environments.

You now understand that biometrics can be assessed in one of two ways. We can use physiological biometrics or attributes that can be measured, such as a face and fingerprints. We can also evaluate behavioral biometrics, which are the way we do things such as signature or gait recognition. Because each individual has both behavioral and physiological characteristics, we may find that using both can complement one another and provide a more robust method to secure a...
