What is a whorl fingerprint pattern?

Back

A whorl fingerprint pattern has circular or spiral ridges that make a complete circuit.

Front

What is the purpose of the Henry Classification System?

Back

Front

What are minutiae in fingerprint analysis?

Back

Minutiae are the unique features of a fingerprint, such as ridge endings and bifurcations, used for identification.
