THINK.CHANGE.DO THE FINGERPRINT DETECTION (R)EVOLUTION Dr Xanthe Spindler Why fingerprints? • Rapid throughput • Maximise chances of identification • Potential for intelligence gathering http://www.moronail.net/img/2018_csi_keep_zooming_in_and_enhancing UTS: Centre for Forensic Science Why fingerprints? Complementary http://www.moronail.net/img/2018_csi_keep_zooming_in_and_enhancing UTS: Centre for Forensic Science Why fingerprints? • Unique • Immutable • Unchanging • Universal (almost!) • Easy to classify • Imprinted on everything we touch! UTS: Centre for Forensic Science The birth of fingerprinting • The incumbent: anthropometry • Challengers: – Sir William Herschel (India) – Dr Henry Fauld (Japan) – Sir Francis Galton (England) – Sir Edward Henry (England) – Dr Juan Vucetich (Argentina) UTS: Centre for Forensic Science The birth of fingerprinting 18911892 1894 19021903 1904 1912 1928 1957 1968 Will West William West UTS: Centre for Forensic Science So who stole the wine?
