Front

What is a whorl in fingerprint patterns?

Back

A whorl is a fingerprint pattern characterized by circular or spiral ridges that form a complete circuit.

Front

What is a loop in fingerprint patterns?

Back

A loop is a fingerprint pattern that has ridges that enter from one side, loop around, and exit on the same side.

Front

What is an arch in fingerprint patterns?

Back

An arch is a fingerprint pattern where the ridges enter from one side and exit from the other side, with no loops or whorls.

Front

What is a plastic fingerprint?

Back

Bifurcation is a type of minutiae where a single ridge splits into two separate ridges.

Front

What is an enclosure (or eye) in fingerprint minutiae?

Back

An enclosure, or eye, is a type of minutiae where a ridge bifurcates and then reunites, forming a small enclosed space.

Front

What is the significance of minutiae in fingerprint analysis?

Back

Minutiae are the unique features of fingerprints that are used to identify individuals, as they vary greatly from person to person.
