2 THE FINGERPRINT  The reader acquires the fingerprint image

3 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.

4 PATTERN IS CREATED  These reference points along with their relative positioning create a pattern which is as unique as the fingerprint image itself

5 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

6 POOR FINGERPRINT REGISTRATION  The reader acquires a poor fingerprint image  This can be due to a number of reasons 1.Incorrect finger placement (refer to end user guide) 2.Damaged collagen ridges under the skin 3.Damaged capillaries under the skin 4.Not enough ridge ends, dots or a ridge junctions (a bifurcation) Damaged collagen

7 POOR FINGERPRINT REGISTRATION = = Good clear image Poor image Enough points registered Not enough points registered Ievo reader will recognise Ievo reader may recognise

8 POOR FINGERPRINT REGISTRATION = Tip of finger scanned: not enough points for recognition

9 POOR FINGERPRINT REGISTRATION = Incomplete finger scanned: Not enough points for recognition Incorrect finger placement on the glass registration plate

10 GOOD FINGERPRINT REGISTRATION = Complete finger scanned: enough points for recognition Try to ensure centre of fingerprint is in the middle of the glass registration plate

11 GOOD FINGERPRINT REGISTRATION = Complete finger scanned: enough points for recognition Try to ensure centre of fingerprint is in the middle of the image

12 GOOD FINGERPRINT REGISTRATION Complete finger scanned: enough points for recognition =

13 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
