unit 3:Fingerprint Analysis and Identification

A collection of flashcards covering key vocabulary and concepts related to fingerprint analysis and identification techniques.

Individual Evidence

Evidence that can be traced back to a unique source, such as fingerprints.

Minutiae Patterns

Points of comparison in fingerprint analysis used to make a match.

Latent Fingerprints

Invisible prints left behind by oils on the fingertips.

Visible Prints

Fingerprints made by fingers touching a surface after contact with colored materials.

Plastic Prints

Ridge impressions left on soft materials.

RUVIS

Reflected Ultraviolet Imaging System, a device used to locate latent fingerprints on non-porous surfaces.

Porous Surfaces

Surfaces that have small spaces to hold liquids or gases, such as paper and clothing.

Non-porous Surfaces

Hard surfaces without pores, such as glass and metal.

Fingerprint Powders

Used to adhere to the oils in fingerprints for visualization.

Ninhydrin

A chemical used to develop fingerprints on porous surfaces by reacting with amino acids to produce a purple color.

Cyanoacrylate Fuming

A technique that reacts with moisture and components in latent prints to produce a white visible material.

Amido Black

A dye that binds with positively charged proteins in blood for fingerprint development.

Superglue Fuming

Process of developing latent prints using cyanoacrylate which creates permanent prints.

IAFIS

Integrated Automated Fingerprint Identification System, a database used for matching fingerprints.

ACEV

Analysis, Comparison, Evaluation, Verification - the process used in fingerprint analysis.
