Document Summary

Alphonse bertilion 1st to develop a system for personal identification: relied on detailed description of the subject, anthropometry= system of precise body measurements (cid:1005)(cid:1012)(cid:1013)(cid:1006): fra(cid:374)(cid:272)is galto(cid:374) pu(cid:271)lished te(cid:454)t(cid:271)ook (cid:862)fi(cid:374)ger pri(cid:374)ts(cid:863) Insisted the british gov. adopt fingerprint as replacement for bertillion system: next step: creation of classification systems for filing multiple prints in a logical order, dr. juan vucetich devised classification system for spanish-speaking countries. Sir edward henry devised classification system for english-speaking countries. Fingerprints= reproduction of friction skin ridges found on the palm side of the fingers + thumbs: basic principles: Fingerprint= individual characteristic because no 2 fingers have identical friction ridges. A fingerprint will remain unchanged throughout a perso(cid:374)"s lifeti(cid:373)e. Fingerprints have general ridge patterns that allow them to be classified. Principle one= the probability of 2 identical fingerprints existing is extremely small: galton calculated that approx. 64 billion different fingerprints exist in the world.
