3D APPLICATION FOR FINGERPRINT

IDENTIFICATION

Ioan ARON1

Abstract: The demonstrations of fingerprint identification presented so far

are based on the examination and processing of digital images in a two-

dimensional system, providing biometric limitations for evaluation when

having to deal with the identification of a person from whom we only have a

print which does not contain sufficient identification elements or when the

print was deposited on a soft base (dough, paint, silicone, wax, gel, etc..),

difficult to reveal by traditional methods, the only method available being

direct photographs that do not alter the details of the print.

Key words: dactyloscopy, print, identification, fingerprint examination,

comparative examination.

1. Introduction

Forensic identification of the person

according to dermal impressions is

scientifically based on the dermal ridge

design properties: uniqueness

(individuality) and fixity (stability) and

inalterability.

The uniqueness of the dermal ridge

pattern was found by researchers in the

field of fingerprint based on the studies

carried out and the practical experience

in this area, who reached the indubitable

conclusion that it is impossible to

meet two people with identical fingerprint

designs, each finger having a unique

morphology .

By developing the human body,

a number of changes intervene due

to age and certain diseases, but the form

of the dermal ridge pattern remains

the same, which demonstrates the

fixity and inalterability of the papillary

design.

Experiments conducted have shown

that taking the fingerprints from a person

at long intervals and comparing them

with each other, it appears that their

structure remains the same, changing

only in size.

There are cases when the burns and deep

cuts affect the dermis and because

of them, after healing, the dermal ridge

pattern is no longer visible, leaving

scars that are very important features

in fingerprint identification, given their

form and the place they occupy

in the morphology of the pattern.

In Romania, coroner Nicolae Minovici

made in 1896 the first research in

dactyloscopy, and the fingerprint recording

and classification system replaced

anthropometry in 1914.

Since 1923 Dr. Andrei Ionescu

established the fingerprint

classification system based on

combining the methods of VUCETICH,

OLORITZ and DAEE.
