Define minutiae in the context of fingerprinting.

Back

Minutiae are the unique features in a fingerprint, such as ridge endings and bifurcations, used for identification.

Front

What is an Island (dot) minutiae?

Back

A type of minutiae that appears as a small dot or island within the ridge pattern.

Front

What is an Ending Ridge minutiae?

Back

Front

What does Bifurcation (fork) refer to in fingerprinting?

Back

A minutiae where a single ridge splits into two separate ridges.

Front

What is a radial loop?

Back

Front

What is the significance of ridge endings in fingerprint analysis?

Back

Ridge endings are critical for identifying unique patterns in fingerprints.

Front

How can you identify a whorl fingerprint pattern?

Back

A whorl pattern has circular or spiral ridges that make at least one complete circuit.

Front

What is the difference between a loop and an arch fingerprint pattern?

Back

A loop has ridges that enter and exit from the same side, while an arch has ridges that rise in the center and exit on opposite sides.
