Fingerprinting Flashcard

Front

What is the core in fingerprint analysis?

Back

The core is the central part of a fingerprint pattern, often used as a reference point for classification.

What are the natural oils on skin responsible for in fingerprinting?

Back

Natural oils on the skin leave behind fingerprints when we touch surfaces, creating a unique pattern.

Front

What is a bifurcation in fingerprint analysis?

Back

A bifurcation is a point where a ridge splits into two, indicating a branching pattern in the fingerprint.

Front

What is an ending ridge in fingerprint analysis?

Back

An ending ridge is a ridge that terminates or ends abruptly, contributing to the unique features of a fingerprint.

Front

What is an arch fingerprint pattern?

Back

An arch is a fingerprint pattern characterized by ridges that enter from one side and exit from the other, forming a wave-like shape.

Front

What is a loop fingerprint pattern?

Back

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

Front

What is a whorl fingerprint pattern?

Back

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

Front

What is the significance of deltas in fingerprint analysis?

Back

Deltas are points where ridge lines diverge, and they are crucial for classifying fingerprint patterns.

Front

How do environmental factors affect fingerprinting?

Back

Environmental factors like moisture can influence the clarity and quality of fingerprints left on surfaces.

Front

What is the primary method used to analyze fingerprints?

Back

The primary method used to analyze fingerprints is ridge counting and pattern classification.
