Document Summary
Overview: friction ridge skin, fingerprint identification, history, current practices (ace-v, future directions, fingermarks as evidence, visible fingermarks, latent fingermarks, detection methods. The general pattern is influences but hereditary not the case for the minute ridge details as these are the result of stress and variable pressure on the friction skin surface during growth of the fetus. Fingerprint identification: two fundamental principles underlying the use of fingerprints as a means of identifying individuals: Immutability: fingerprints do not change after they have formed: uniqueness: random nature of ridge characteristics, even for identical twins, more than a century of accumulated study but uniqueness difficult to prove empirically, general theory supported by mathematical models. Identical twins share the same dna profiles but have different fingerprints. History: 1880 henry faulds, a scottish missionary doctor, recognised the identification value of fingerprints and that the patterns did not change over time.
