Poroscopy

Fingerprints have been used as a vital tool in §personal identification for over a century due to §their uniqueness and permanence. Despite of the fact §that these are unique and permanent, there have been §occasions when fingerprint science has been §challenged. Recent cases of erroneous identification §in Shirley McKie, Stephan Cowans and Brandon §Mayfield cases raised doubts on the reliability of §fingerprint evidence. This has lead forensic §community to look for extended set features to give §further boost to this vital tool and to further §increase its potential as evidence. One of these §efforts lead to the use of third level features (&§sub-features) in existing identification system. §This book introduces to the readers the authenticity §of third level sub-features, in particular §poroscopy, in personal identification. This book §focuses on:§1.The effect of substrate on the reproducibility of §inked fingerprint pore dimensions §2.Pore area reproducibility in latent prints §developed using Cyanoacrylate and Ninhydrin §development methods§3.Reproducibility of pore area in Direct §microscopic images.
