THINK.CHANGE.DO T HE FINGERPRINT DETECTION ( R ) EVOLUTION Dr Xanthe Spindler

Why fingerprints? • Rapid throughput • Maximise chances of identification • Potential for intelligence gathering UTS: Centre for Forensic Science http://www.moronail.net/img/2018_csi_keep_zooming_in_and_enhancing

Why fingerprints? Complementary UTS: Centre for Forensic Science http://www.moronail.net/img/2018_csi_keep_zooming_in_and_enhancing

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
