Czajka) Privacy & Security 3 The history of fingerprint recognition 4 1684: Nehemiah Grew • First scientific work on fingerprint structure. • Description of ridges, valleys, and sweat pores 5 1686: Marcello Malpighi • First classification of fingerprints - Definition of similar patterns that could be grouped • Similar work done centuries later - John Purkinji (1823, Poland) - Sir Edward R. Henry (1899, UK) 6 1850s: Sir William Herschel • Noted the role of fingerprints for identification • Understood the uniqueness and permanence of fingerprints • Recognized the legal value of fingerprints - Used fingerprints for contracts during his time as an officer in the Indian Civil Service 7 1880: Henry Faulds “Fingerprints from corpse no 125” • First experiments showing the uniqueness of fingerprints • First forensic use of a latent fingerprint left on a bottle - Exoneration of a burglary suspect in Tokyo 8 1888: Sir Francis Galton Galton, “Finger Prints.” New York: MacMillan and Co., 1892, 113. • Definition and classification of fingerprint “singular points” • Definition of minutiae (a.k.a. Galton’s Details) • Experiments demonstrating the high temporal stability and uniqueness of fingerprints - Estimated identification error probability of 1 in 64 billion 9 Mr. Galton also published a book… NY Times Book Review, Jan. 1st, 1893 “What Mr. Galton wants to show is that through the prints made by the finger tips we have an absolute method of identification. As to that stupid thing, palmistry, our authority says it has no more significance than the creases on old clothes.” “When one comes to the real practical use of the finger-mark method it seems to have none. If there be any reliance to be put in it as a means of identification it would require an expert having uncommon powers of observation.” Published: January 1, 1893 Copyright © The New York Times 10 Bertillonage System Suspect identification in the late 19th century • Lengths of bone • Attributes - height - weight - eye color 11 1903: Oops! • William West and Will West institutionalized at the same time at the Leavenworth penitentiary • Will West’s Bertillon record precisely matched that of William West (no relation) • Case undermined the entire Bertillonage System 12 1892: Juan Vucetich Rojas Case •Mother murders children; bloody fingerprint recovered at the scene •First criminal case where fingerprints were used to convict the suspect 13 1910: Edmond Locard • Experiments to derive the number of matching features required in court: 12 ‣ A defendant is pronounced guilty if at least 12 features match in the sample and reference material Image source: http://janinetissot.fdaf.org/jt_locard.htm Exchange Principle: when committing a crime we always leave something at the scene, and take something with us 14 1903-1924: Common Acceptance of Fingerprints • 1903: Scotland Yard begins to use fingerprints • 1915: Founding of the International Association for Identification • 1924: Fingerprint Identification Division established at the FBI 15 What did we know at the beginning of the 20th century? 1. Individual features of the fingerprints are unique in different fingers and stable over time (foundation of fingerprint recognition) 2. Fingerprint ridges and valleys can be grouped by similar shapes observed across the human population (foundation of fingerprint classification) 16 What do we observe from the finger? 17 Zooming in on the fingerprint surface 1. Base elements: ridges and valleys 2. Level 1 features: core and singular points 3. Level 2 features: minutiae (Galton’s details) 4. Level 3 features: sweat pores, incipient ridges, warts, scars, creases 18
