Introduction

The biometric recognition system responds to automated based on artificial intelligence and pattern recognition, which enables identification and / or verification of the identity of persons from morphological or behavioral characteristics. The major systems are fingerprints (AFIS), hand geometry, face, facial thermo gram (facial Recognition, iris, retina, voice, style writing, etc. Also, the wild-type characteristic morphology or behavior, directly related to the degree of variation over the same time, being much lower in the former case than in the second, and as we know, the behavior is closely psychological factors related to these yes they are direct function of time.

Automated Fingerprints Identification System

The technology has been developed through, computer automation systems for fingerprint identification (AFIS), which based on the most advanced techniques of applying computer science to carry out in minutes the search function and comparing, Thus, ten print fingerprint chip as latent prints that would require days if using the normal method. AFIS system is to convert existing paper files in magnetic files, regardless of the fingerprinting system which fingerprints are classified. It is done through a procedure or photo detectors, a digital imaging (scanning), which directly reads the information displayed in ten print chips, this process is called conversion. The information for each fingerprint is digitally encoded by a high speed computer to facilitate processing. This makes AFIS systems, are highly effective and easy to operate. (Wilson, 1997)

AFIS systems offer great advantages such as: discrimination, i.e. can be selected with great precision to a few, candidates, including a voluminous file of fingerprints, to identify both latent and ten print cards, store information such as name, age, sex and date of birth, can integrate information such as the type of crime, instead of smuggling etc. Another big advantage is speed. Has the ability to "auto search", i.e. conducts searches and matches without having a list of suspects. AFIS systems are able to operate independently or as part of a network, which can be fully autonomous. One of its most important features is to be integrated to other devices or databases, both remote and local to cover larger geographical areas.

The main technical characteristics of an AFIS system are:

Quick and automatic conversion of fingerprints into digital information.

Encoding latent or low-quality ten print auxiliary capacities to give a treatment that improves water quality.

Manually editing low-quality ten print cards automatically encrypted.
