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.
