Fingerprint Patterns & Minutiae

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, resembling a fork.

Front

Define ridge ending in the context of fingerprints.

Back

A ridge ending is a type of minutiae where a ridge terminates abruptly, indicating the end of a fingerprint ridge.

Front

What is a bridge in fingerprint patterns?

Back

A bridge is a type of minutiae that connects two ridges, forming a small bridge-like structure.

Front

Explain what an island (dot) is in fingerprint analysis.

Back

An island, also known as a dot, is a small ridge that is isolated and surrounded by empty space, resembling a dot.

Front

What are deltas in fingerprint patterns?

Back

Deltas are points on a fingerprint where two ridges diverge, forming a triangular shape, often found in whorls.

Front

Identify the term: short ridge.

Back

A short ridge is a small segment of a ridge that does not extend the full length of a typical ridge.

Front

What is a hook in fingerprint minutiae?

Back

A hook is a type of minutiae that resembles a hook shape, where a ridge curves back on itself.

Front

Define trifurcation in fingerprint analysis.

Back

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

Front

What is the significance of minutiae in fingerprint identification?

Back

Minutiae are critical for fingerprint identification as they provide unique characteristics that differentiate one fingerprint from another.

Front

Explain the term 'loop' in fingerprint patterns.

Back

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