Fingerprints + Minutiae

Front

What is a minutiae in fingerprint analysis?

Back

Minutiae are the specific features of a fingerprint, such as ridge endings and bifurcations, that are used to identify and compare fingerprints.

Front

Define 'Enclosure' in the context of fingerprints.

Back

An enclosure, also known as an 'eye', is a type of minutiae where a ridge bifurcates and then rejoins, forming a closed shape.

Front

What is a 'Bifurcation' in fingerprint terminology?

Back

A bifurcation, or fork, is a minutiae where a single ridge splits into two separate ridges.

Front

What does 'Delta' refer to in fingerprint patterns?

Back

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

Front

What is the significance of 'Ridge Ending' in fingerprint analysis?

Back

A ridge ending is a type of minutiae where a ridge terminates abruptly, which is crucial for fingerprint identification.

Front

What percentage of the population has 'Arches' as their fingerprint pattern?

Back

5% of the population has arches as their fingerprint pattern.

Front

What is the difference between 'Loops' and 'Whorls' in fingerprint patterns?

Back

Loops are fingerprint patterns that enter from one side and exit the same side, while whorls are circular patterns that have two or more deltas.

Front

Define 'Island' in fingerprint analysis.

Back

An island, also known as a dot, is a small, isolated ridge that appears within a fingerprint.

Front

What are 'Pores' in the context of fingerprints?

Back

Pores are small openings in the skin that can be found on ridges of fingerprints, often associated with sweat glands.

Front

Explain the term 'Ridge Count' in fingerprint analysis.

Back

Ridge count is the number of ridges between the core and the delta in a fingerprint pattern, used for classification.
