Fingerprint Patterns & Minutiae

Front

What is an accidental whorl?

Back

An accidental whorl is a fingerprint pattern that does not fit into the standard categories of loops, whorls, or arches. It contains features of more than one type of pattern.

Front

What is the core in fingerprint analysis?

Back

The core is the central part of a fingerprint pattern, typically found in whorls and loops, where the ridges converge.

Front

What is a short ridge in fingerprint minutiae?

Back

A short ridge is a type of minutiae that appears as a small segment of a ridge that does not connect to other ridges.

Front

What is a trifurcation in fingerprint analysis?

Back

A trifurcation is a type of minutiae where a single ridge splits into three separate ridges.

Front

What are the three main types of fingerprint patterns?

Back

The three main types of fingerprint patterns are loops, whorls, and arches.

Front

What is a bifurcation in fingerprint minutiae?

Back

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

Front

What is a delta in fingerprint analysis?

Back

A delta is a point on a fingerprint pattern where two ridges diverge, forming a triangular shape.

Front

What is a loop in fingerprint patterns?

Back

A loop is a fingerprint pattern characterized by ridges that enter from one side, curve around, and exit the same side.

Front

What is a whorl in fingerprint patterns?

Back

A whorl is a fingerprint pattern that has circular or spiral ridges, with at least two deltas.

Front

What is an arch in fingerprint patterns?

Back

An arch is a fingerprint pattern where ridges enter from one side and exit the other side, without any cores or deltas.
