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
