Finger Print Study guide

Alphonse Bertillon

Developed anthropometry, a system of detailed physical measurements and photographs for identification.

William Hershel

Pioneered the use of fingerprints in India by requiring natives to sign contracts with their handprints.

Francis Galton

Authored significant texts on fingerprints and established their uniqueness and permanence.

Dr. Juan Vucetich

Created a classification system for fingerprints that is still in use in many Spanish-speaking countries.

Sir Edward Henry

Developed a widely adopted classification system for fingerprints in English-speaking countries.

Fingerprint

A reproduction of the friction skin ridges found on the palm side of fingers and thumbs, unique to each individual.

Minutiae

Refers to the unique ridge characteristics of fingerprints that are critical for identification.

Analysis in ACE-V Method

Evaluates the quality of the fingerprint, identifying ridge patterns and distortions.

Henry Classification System

Assigns a numerical classification based on the presence of whorls in specific fingers.

Automated Fingerprint Identification System (AFIS)

Allows for the digital encoding of fingerprints, enabling high-speed processing and retrieval.

Identification

Concludes that two pieces of evidence share enough unique characteristics to originate from the same source.

Exclusion

Indicates that the evidence does not match, ruling out a connection between the prints.

Inclusion

Indicates insufficient data to make a definitive identification or exclusion.

2D Impressions

Prints left on flat surfaces, such as shoeprints in dust or ink.

3D Impressions

Formed in soft materials like soil or snow, capturing the depth and shape of the object.

Tire Track Analysis

Involves analyzing features like tread pattern, width, and unique wear characteristics.

Bitemark Comparison

Involves examining the type of bitemark, characteristics of teeth, and swabbing for DNA.

Interdigital Area

Class characteristics include general ridge flow; individual characteristics include unique ridge formations.

Thenar Area

Class features a half-moon pattern and individual features include distinct ridge formations.

Hypothenar Area

Class exhibits a 'down and out' pattern; individual characteristics include unique ridge details.
