Latent Fingermark Development:Literature Review and Prospect
摘要
Abstract
Fingermark is one of the most valuable physical evidence and generalized proof of identity for its characteristics of specialty and stability. Latent fingermark, the most common evidence, poses the most challenges when being examined to show contrast present yet non-sufficient between the mark and its support. Surface phenomena and environmental conditions play an important role in the choice of fingerprint detection techniques. In general, all surfaces bearing latent fingermarks can be divided into three types: porous, semi-porous and nonporous. Property of an unknown surface has to be considered before any attempt is made to develop latent fingermark. Preliminary test should be conducted on a similar surface before proceeding with any treatment of an evidential item. Along with the fingermark detection technology being improved, the process has been further optimized and its sensitivity and specificity being advanced. In this paper, the latest techniques and material used in different surfaces to enhance and record fingermarks are reviewed. A larger number of techniques are presented here and discussed according to surface properties from practical perspective. For example, optical detection, fingerprint powder, small-particle reagent (SPR), cyanoacrylate fuming and vacuum metal deposition (VMD) can be used to nonporous surface. Ninhydrin, physical developer (PD) can be used to porous surface, some miscellaneous techniques can be applied to a wide range of porous and nonporous surfaces, even for some challenging surfaces. Furthermore, some modern instrument analysis techniques can be used to enhance the visualization of latent fingermarks. Finally, we summarize the advance of research on the development of latent fingermarks, discuss the challenges facing the fingermarks examiners, and predict the future and perspective research of latent fingermarks development.关键词
