AFIS TECHNOLOGY

Axis AFIS an enhanced Automated Fingerprint Identification System meets the dynamic challenges faced by the Civil Government & Law Enforcement Agencies and Enables Businesses by providing technology for their Growth. The Axis AFIS is designed to curb identity fraud by validating a person unique identity, and by verifying identity information of persons claiming a right to services or benefits. Axis AFIS essentially does Identification & Restores Public Trust Origination can save money by deterring those who pray on their benefits program. But more than the money saved and the fraud detected they can restore the public's trust. And for the truly deserving that's priceless.

D
edicated to fingerprint software / matching and searching technologies for high end low cost fingerprint search systems (AFIS), Axis Software's business is focused in fingerprint search identification. Axis Software provides a wide range of fingerprint matching and software services. We supply complete fingerprint software / hardware search system products. Axis also assists agencies in fingerprint identification system design, system development and implementation and fingerprint software, right up to supplying a complete fingerprint ID system

As suppliers of the algorithmic fingerprint software components and subsystems that are the heart of any fingerprint search system, Axis prides itself on accuracy

 

Fingerprint Software / Systems >>

Axis has a complete suite of fingerprint processing algorithms, which is integrated into identification system package. The software suite performs the following tasks :

Image Processing >>
Captured fingerprint images are processed through a series of image processing algorithms to obtain a clear unambiguous skeletal image of the original gray tone impression, clarifying smudged areas, removing extraneous artifacts and healing most scars, cuts and breaks.
         
Feature Detection for Matching >>

Ridge ends and bifurcations (minutiae) within the skeletal image are identified and encoded, providing critical placement, orientation and linkage information for the matcher.

   
Matching Fingerprint Search >>

The "hyperladder" matcher then compares data from the input search print against all appropriate records in the database to determine if a probable match exists. Even prints of poorer quality, if they contain sufficient hyperladder match criteria, are identified.

The software provided is both innovative and robust:

 

Robust to image quality >>

Scanned and camera captured live and inked fingerprints are often blurred, smudgy or broken up (as below). Ridges often show discontinuities and vary greatly in contrast. Scars and creases may exist or disappear, depending on when the print is taken, and of course, fingers can be dirty.

The image processing technology used by Axis is designed to be maximally robust to these problems.We clean up and "clarify" the finger image before encoding a print, minimizing to the maximum extent possible the "garbage in, garbage out" problem.

 

Robust to finger placement >>

Finger placement in the center of a finger scanner platen is not critical using our software. Capture of finger image data by camera from paper copy does not require the centering of the finger image under the camera. The area of interest detector (part of the image processing algorithm suite) locates and processes the finger image, regardless of location. No core or other reference point within the fingerprint is necessary.

Robust to finger orientation >>

We will match a finger that has been placed on the platen at any angle. We are not concerned about finger orientation. Our orientation independent code demonstrates with subjects routinely placing their fingers at odd angles, even upside down on the finger scanner platen

The bottom line is that our image processing, encoding and matching algorithm suite is the best currently available in the industry. The algorithms have been designed to perform well under adverse conditions. They provide high accuracy with minimal false positives. They work with images rejected by most other systems
