Fingerprints

Front

What are minutiae in the context of fingerprints?

Back

Minutiae are the unique features in a fingerprint pattern, such as ridge endings, bifurcations, and dots, that help in identifying and differentiating fingerprints.

Front

What is the significance of deltas in fingerprint patterns?

Back

Deltas are points where ridge lines diverge, and they are crucial for classifying fingerprint patterns. A plain whorl typically has 2 deltas.

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 the most common fingerprint pattern?

Back

Loops are the most common fingerprint pattern, making up about 60-70% of all fingerprints.

Front

What does AFIS stand for?

Back

AFIS stands for Automated Fingerprint Identification System, a technology used to automatically match fingerprints against a database.

Front

How do arches differ from other fingerprint patterns?

Back

Arches have ridges that enter on one side and exit on the other side, unlike loops and whorls which have more complex patterns.

Front

What is the role of fingerprint analysis in forensic science?

Back

Fingerprint analysis is used in forensic science to identify individuals based on the unique patterns of their fingerprints, aiding in criminal investigations.

Front

How can fingerprints be classified?

Back

Fingerprints can be classified based on their patterns: loops, whorls, and arches, as well as by the number of deltas and core points.

Front

What is the purpose of using minutiae in fingerprint identification?

Back

Minutiae are used in fingerprint identification to create a unique fingerprint profile, allowing for accurate matching and verification.

Front

What is the difference between a loop and a whorl fingerprint?

Back

A loop fingerprint has ridges that enter and exit from the same side, while a whorl has circular or spiral patterns with at least two deltas.
