Fingerprinting Requirements 1.Give a short history of fingerprinting.

Name the surfaces of the body where friction or papillary ridges are found. b. Name the two basic principles supporting the science of fingerprints and give a brief explanation of each principle. c.

Make these on an 8-by-8-inch fingerprint identification card available from your local police department or counselor. b. Using clear adhesive tape, a pencil, and plain paper, record your own fingerprints or those of another person. 5.Show your merit badge counselor you can identify the three basic types of fingerprint patterns and their subcategories. Using your own hand, identify the types of patterns you see.
Why Do We Use Fingerprints? A very good way to identify people who might look alike, or who try to hide their real identity like identical twins DNA of identical twins is the same but not their fingerprints Fingerprints are permanent they never change They have individuality no 2 are the same
History (part 1) Ancient History fingerprints used in many cultures as identifying marks for legal documents and contracts. 1686 - Marcello Malpighi notes the common characteristics of spirals, loops and ridges in fingerprints, using the newly invented microscope for his studies. 1880 - Dr. Henry Faulds, a British surgeon and Superintendent of a Hospital in Tokyo, published an article where he discussed fingerprints as a means of personal identification, and the use of printers ink as a method for obtaining such fingerprints. Solved a murder by matching the killers prints to prints on a bottle at the scene. 1888 - Sir Francis Galtons became the first to provide scientific evidence that no two fingerprints are exactly the same, and that prints remain the same throughout a persons lifetime. He calculated that the odds of finding two identical fingerprints were 1 in 64 billion (.00011 in a 100 billion today, according to certain studies and the use of computer analysis). 1896 - British official Sir Edward Richard Henry developed a finger print identification system of his own, which included 1,024 primary classifications. 1901 - Henry began training investigators to use the Henry Classification System after founding Scotland Yard's Central Fingerprint Bureau. Within a few years, the Henry Classification System was in use around the world, and fingerprints had been established as the uniform system of identification for the future. The Henry Classification System is still in use today in English speaking countries around the globe.
History (part 2) 1902 - Alphonse Bertillon, director of the Bureau of Identification of the Paris Police, is responsible for the first criminal identification of a fingerprint without a known suspect. 1924 - The U.S. Congress acts to establish the Identification Division of the F.B.I. The National Bureau and Leavenworth are consolidated to form the basis of the F.B.I. fingerprint repository. By 1946, the F.B.I. had processed 100 million fingerprint cards; that number doubles by 1971. 1990s - AFIS, or Automated Fingerprint Identification Systems, begin widespread use around the country. This computerized system of storing and cross-referencing criminal fingerprint records would eventually become capable of searching millions of fingerprint files in minutes, revolutionizing law enforcement efforts. 1999 - The FBI phases out the use of paper fingerprint cards with their new Integrated AFIS (IAFIS) site at Clarksburg, West Virginia. IAFIS will starts with individual computerized fingerprint records for approximately 33 million criminals, while the outdated paper cards for the civil files are kept at a facility in Fairmont, West Virginia.
The Difference Between Criminal Fingerprinting and Biometric Fingerprinting Who are you? Criminal Identification Vs Who you are. Civil Identification grants you access to something (computers buildings etc)
Automated Fingerprint Identification System - AFIS
How Fingerprints Work Friction Skin is on your palms, feet and fingers Humans and only a few other animals like primates have friction skin Oils, dirt and other substances can be transferred to smooth objects to leave prints
Types of Finger Prints 60% - 65% 30% - 35% 5%
How does an examiner determine one from the other? Latent print identification relies on three levels of detail 1. Ridge flow (patterns) Level 1 detail loop, whorl, or arch (and subcategories) 2. Ridge formations (ridge Level 2 detail endings, bifurcations, dots, or combinations) 3. Ridge path deviation (ridge Level 3 detail - structure or formation, which includes ridge width, shape, pores and other details)
