THE FINGERPRINT

The reader acquires the fingerprint image

UNIQUE POINTS IDENTIFIED

Each fingerprint contains unique reference points known as ‘Minutiae’

These are located where a ridge ends, at a dot or a ridge junction (a bifurcation)

A reader can identify and acquire up to 100 points.

PATTERN IS CREATED

These reference points along with their relative positioning create a pattern which is as unique as the fingerprint image itself

THE ALGORITHM ENCRYPTS

The pattern is then converted into a binary code via an algorithm

The binary code is encrypted and transferred onto the ievo board

Note: It is impossible to re-create the original fingerprint image from this code or its pattern

POOR FINGERPRINT REGISTRATION

The reader acquires a poor fingerprint image This can be due to a number of reasons1. Incorrect finger placement (refer to end user

guide)2. Damaged collagen ridges under the skin3. Damaged capillaries under the skin4. Not enough ridge ends, dots or a ridge

junctions (a bifurcation)

THE TECHNOLOGY

Multi-Spectral Imaging (MSI) – quality of fingerprint image

Other Biometric Readers Image

I-Evo Reader Image

The image that is captured is encrypted and stored, it can not be reproduced from the database in which it is stored, therefore:-

iEvo does not contravene data protection or human right laws iEvo is not the same method the Police use when taking fingerprints
