Fingerprint Evidence: Classifying Fingerprints

What is the difference between a plain whorl and a central pocket whorl?

• A plain whorl has a circular pattern where the line between the deltas cuts through the ridge line circles.

• A central pocket whorl has a circular pattern that is interrupted by a delta.

• A plain whorl has no circular pattern and is irregular in shape.

• A central pocket whorl has multiple deltas that intersect with the ridge lines.

What is a double loop whorl?

• A fingerprint pattern with two loops that swirl around each other.

• A fingerprint pattern with a single loop.

• A fingerprint pattern that consists of straight lines.

• A fingerprint pattern that has no identifiable features.

What is a tented arch in fingerprint classification?

• A type of fingerprint pattern where the ridge lines come in from one side, rise to a point in the middle, and exit on the other side.

• A fingerprint pattern characterized by circular whorls and loops.

• A pattern that resembles a series of parallel lines without any elevation.

• A fingerprint type that has no distinct ridge patterns and appears smooth.

What are deltas in fingerprint analysis?

• Points on a fingerprint where ridge lines converge

• Points on a fingerprint where ridge lines diverge, typically found in loop and whorl patterns

• The central core of a fingerprint

• The overall pattern of a fingerprint

What is an arch in fingerprint classification?

• A ridge line that comes in from one side, goes up in the middle, and leaves on the other side.

• A circular pattern of ridges that resembles a whorl.

• A series of parallel lines that run in the same direction.

• A pattern that consists of a series of loops that connect to each other.

What are the two main types of arches in fingerprint classification?

• Plain arch and tented arch

• Loop and whorl

• Radial and ulnar

• Composite and simple

What is a Central Pocket Whorl?

• A type of fingerprint where the line between the deltas cuts through the ridge line circles.

• A type of whorl fingerprint where the line between the deltas does not cut through the ridge line circles.

• A fingerprint pattern characterized by a series of parallel lines.

• A type of fingerprint that has no identifiable patterns.

What is the significance of fingerprint classification?

• It helps in identifying individuals based on unique patterns, aiding in forensic investigations.

• It is used to create digital signatures for online transactions.

• It serves as a method for storing personal information securely.

• It is primarily used for artistic purposes in design and fashion.
