BrandPost: Introduction to Biometric Modalities

You might associate biometrics with the fingerprint scanner on your smartphone, or the face camera at the airport, but in truth there are a wide range of biometric types, or modalities.

Every biometric modality works along the same basic principle: capture and measure specific biological (anatomical and physiological) or behavioral characteristics, analyze them to create and store a digital representation called a template, then match new captures against the template to verify identity. Where they differ is in what’s captured, how it’s captured, and how easy and accurate the process is.

Friction ridge biometrics identify, store, and compare the complex patterns of the friction ridges found on the fingers or toes, the soles of the feet, and the palms of the hand. Formed in the womb, these ridges are unique to every person and are permanent – two key features of any effective biometric. The technology to capture, analyze, and store friction ridge patterns is already familiar and mature; the capture process is fast and very accurate.
