Minutiae

Front

What is a dot in the context of minutiae?

Back

A dot is a type of minutiae that appears as a small point or dot in fingerprint analysis.

Front

What is a bifurcation in fingerprint analysis?

Back

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

Front

What are the three main fingerprint patterns?

Back

The three main fingerprint patterns are Loop, Arch, and Whorl.

Front

What is the core in fingerprint analysis?

Back

The core is the central area of a fingerprint pattern, often found in whorls and arches.

Front

What is a ridge ending?

Back

A ridge ending is a type of minutiae where a ridge terminates abruptly.

Front

What is an island in fingerprint analysis?

Back

An island is a type of minutiae that appears as a small ridge that is completely surrounded by other ridges.

Front

What is a spur in fingerprint analysis?

Back

A spur is a type of minutiae that resembles a small branch or spur off a ridge.

Front

What is the difference between a loop and an arch?

Back

A loop has one or more ridges that enter from one side, loop around, and exit on the same side, while an arch has ridges that enter from one side and exit on the opposite side without looping.

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

How can you identify a whorl pattern?

Back

A whorl pattern can be identified by the presence of circular or spiral ridges that form a complete circuit.
