Abstract

Fingerprints are considered to be most reliable for the personal identification of individuals in criminal investigations, civil disputes and also for routine identification purposes. At different social statuses; there is a need of verification of personality. The most vital and conventional clue in any crime in most circumstances is the fingerprints. Molecular Fingerprints is the new technology in which fingerprint residues contain a large number of inorganic and organic substances in them. Though the inorganic components are present in every fingerprint residue, the presence of those elements/ mineral components may be present in abnormally higher levels indicating / prompting the subject’s specific association of them with these elements eitherduetotheiroccupation,consumptionandconstantexposureofsuchelements/minerals or due to the environment with the abundance of such elements in fingerprint residues. This paper reviews many literatures that used only morphometric analysis of the minutiae details or third level details which includes the pore dimensions of fingerprint for Personal Identification. As far as what we found in literature, the study is only limited to Morphometric Analysis. However,basedontheliteraturewereviewed,tofillinguptheexistingresearchgap,advanced instrumentation techniques were used for the analysis of the elemental composition of the human sweat collected from the fingerprint.
