Sutton- University of Wolverhampton, UK - Forensic Science International Vol. 179, Issues 2-3 6 August 2008, Pages 172-175 ABSTRACT- The study of the reproducibility of friction ridge pore detail in fingermarks is a measure of their usefulness in personal identification. Pore area in latent prints developed using cyanoacrylate and ninhydrin were examined and measured by photomicrography using appropriate software tools. The data were analysed statistically and the results show that pore area is not reproducible in developed latent prints, using either of the development techniques. The results add further support to the lack of reliability of pore area in personal identification.

Unusual, Genius, Stupid Tactics for More Fingerprint and Facial Identifications - Ed German 2016 IAI Presentation
November 30, 2009 The National Institute of Justice (NIJ) has awarded researchers at Virginia Tech a two-year, $854,907 grant to develop a quantitative approach to measuring and establishing a standard for "standard for "sufficiency" of information available in friction ridge (fingerprint) patterns.
With issuance of the 1973 IAI resolution which stated, "That no valid basis exists at this time for requiring that a pre-determined number......", the standardization committee strongly recommended a federally funded study of fingerprints. Twenty-seven years later a solicitation for such a study was issued.
The grant funding for this solicitation was recalled and the solicitation was rewritten to include all pattern evidence sciences. This does not infer that friction ridge individualization validation is not needed. The
National Institute of Justice (NIJ) has identified the need for
validation of
