Fingerprint Test 1 Review

What are the three basic fingerprint patterns?

• Star, Diamond, Oval

• Spiral, Zigzag, Swirl

• Square, Triangle, Circle

• Arch, Loop, Whorl

How are fingerprints analyzed in forensic science to determine identity?

• By comparing the unique patterns to a known database of fingerprints

• By analyzing the color of the fingerprint

• By counting the number of ridges on the fingerprint

• By measuring the temperature of the fingerprint

Describe the history of fingerprinting and its evolution as a forensic identification technique.

• Fingerprinting has been used for centuries, but it is not accurate for forensic purposes.

• Fingerprinting has a long history and has evolved into a reliable forensic identification technique.

• Fingerprinting was only recently discovered and is not a reliable forensic identification technique.

• Fingerprinting was initially used for art authentication, not for forensic identification.

What is the scientific basis for the uniqueness of fingerprints?

• Temperature of the hand

• Pattern of ridges and valleys on the skin's surface

• Number of freckles on the fingers

• Color of the skin

Discuss the role of fingerprints in criminal investigations and how they are used as evidence in court.

• Fingerprints are used to identify suspects and link them to the crime scene, serving as crucial evidence in court.

• Fingerprints are only used for identification and have no relevance in criminal investigations.

• Fingerprints are not admissible as evidence in court due to their unreliable nature.

• Fingerprints are often planted at the crime scene by the real criminal to mislead investigators.

Explain the concept of latent fingerprints and the techniques used to develop them for analysis.

• Latent fingerprints are impressions left by the friction ridge skin on human elbows. Techniques used to develop them for analysis include using a pencil eraser, applying lipstick, and using a feather duster.

• Latent fingerprints are impressions left by the friction ridge skin on human fingers. Techniques used to develop them for analysis include dusting, chemical methods, and alternate light sources.

• Latent fingerprints are impressions left by the friction ridge skin on human toes. Techniques used to develop them for analysis include blowing air on the surface, using a vacuum cleaner, and applying lotion.

• Latent fingerprints are impressions left by the friction ridge skin on human palms. Techniques used to develop them for analysis include washing the surface with water, using a hairdryer, and applying glitter.

How do modern biometric systems use fingerprints for identification and authentication?

• Scanning the fingerprint and comparing it to a database of known fingerprints

• Analyzing the color of the fingerprint and using it for authentication

• Capturing an image of the fingerprint, extracting unique features, and converting them into a digital template for comparison

• Measuring the temperature of the fingerprint and using it for identification

What is the process of lifting fingerprints from a crime scene?

• By using a magnifying glass and sketching the fingerprint

• By using a special adhesive tape and a lifting card

• By using a camera to take a picture of the fingerprint

• By using a paintbrush and watercolors

What is the principle behind the persistence of fingerprints?

• Fingerprints remain unchanged throughout an individual's lifetime

• Fingerprints change every few years

• Fingerprints are influenced by the individual's diet

• Fingerprints change with the seasons

What is the significance of minutiae in fingerprint analysis?

• Minutiae are irrelevant in fingerprint analysis

• Minutiae refer to the color variations in a fingerprint

• Minutiae are the unique ridge characteristics in a fingerprint

• Minutiae refer to the temperature variations in a fingerprint
