Chapter 9: Considering Alternate Biometrics
Many of us are familiar with the more common biometrics, such as face, fingerprint, and iris recognition. However, each of us has other unique features we can explore as alternate biometrics. In this chapter, we’ll take a look at the lesser-known biometrics that are in use today or have the potential to be used in the future.
We’ll learn how we can use other elements of the hand as a biometric identifier. In addition to using our hand to obtain fingerprints, we can also use palm prints, hand geometry, and palm veins. We’ll then cover how we can use gait recognition, or the way we walk, as a viable biometric. You’ll see how gait recognition is a passive biometric that is optimal for threat management in large venues such as malls and arenas.
Although not used as much, you’ll see why using deoxyribonucleic acid (DNA) and the retina provides strong spoof-proof biometrics when security is imperative....
