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)

Presentation Transcript

  1. THE FINGERPRINT • The reader acquires the fingerprint image

  2. 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.

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

  4. 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

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

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

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

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

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

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

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

  12. 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
