fingerprint classification a procedure in which fingerprints are grouped in a consistent and reliable way, so that different impressions of a same finger fall into a same group.
ridge characteristics(Galtons details) ridge endings, bifurcation, enclosures and other ridge details which must match in two fingerprints to establish their common origin
invisible fingerprints those not readily seen but that can be developed through powders or chemicals
inked fingerprint
latent fingerprint print impressions caused by perspiration on the ridges of the fingers being transferred to a surface or occurring as residues of oil, dirt, or grease
patent(plastic) fingerprint fingerprints that are easily spotted without the use of magnesium powders, ultra violet lights or chemicals that might assist in the visualization of such a print.
arches ridges flow in one side and flow out the opposite side. There are no deltas in an arch pattern.
loops a loop class of fingerprints characterized by ridge lines that enter from one side of the patter and curve around the exit from the same side of the pattern
whorls something that whirls, coils, or spirals or whose form suggests such movement
voice prints graphic record of an individual's voice characteristics made by a sound spectrograph that records energy patterns emitted by speech
scientific basis of fingerprint identification
A.F.I.S the automated fingerprint identification system is a bio-metric identification (ID) methodology that uses digital imaging technology to obtain, store, and analyze fingerprint data.
dissimilarity the difference in the fingerprints
discrepancy a lack of similarity between two facts or objects
dactylography the impression on a surface of the curves formed by the ridges on a fingertip; especially, such an impression made in ink and used as a means of identification
core the most important part of something
individualization the development of individual traits
class one/level one detail
class two/level two detail
