Fingerprinting Analysis

Why are fingerprints important?

• To analyze DNA profiles

• To track the location of a person

• To identify individuals based on unique patterns

• To determine the age of a person

How do you think fingerprinting is different from the late 1800s to now?

• Increased use of anthropometry for identification

• Introduction of automated fingerprint identification systems

• Decreased reliance on fingerprint patterns

• No significant changes in fingerprinting methods

What do you think is more valuable DNA or fingerprints? Why?

• Fingerprints, because they are truly unique to each individual

• DNA, because it provides more accurate identification

• Neither is valuable for identification purposes

• Both are equally valuable for identification purposes

What are ridge characteristics?

• Features that determine individuality in fingerprints

• Patterns found on the thickest portion of the finger pad

• Visible prints left by an individual on a surface

• Impressions made on a soft, malleable surface or object

What are the fingerprint patterns?

• Arches, loops, and whorls

• Primary, secondary, and tertiary patterns

• Plain, tented, and accidental whorls

• Visible/patent, latent, and plastic prints

What are the types of fingerprint impressions?

• Arches, loops, and whorls

• Primary, secondary, and tertiary impressions

• Plain, tented, and accidental whorls

• Visible prints/patent prints, plastic prints, and latent prints

Why are alternative light sources important?

• They can capture latent fingerprints without any physical or chemical treatment on a surface

• They are used to visualize fluorescent fingerprints

• They help in developing latent prints on porous substrates

• They provide additional lighting for crime scene investigations

How are fingerprints compared?

• By analyzing the size of pores on the papillary ridges

• Using AFIS and manual comparison by fingerprint experts

• By using reflective ultraviolet imaging systems

• By capturing latent fingerprints using chemical reagents

What is the role of minutiae in fingerprint analysis?

• They are used to determine the age of the individual

• They are unique features in fingerprint patterns used for identification

• They are used to determine the gender of the individual

• They are used to determine the race of the individual

What is the significance of latent fingerprints in crime scene investigations?

• They are used to determine the time of the crime

• They are used to identify potential suspects

• They are used to determine the cause of the crime

• They are used to determine the location of the crime
