  • In few years, we expect the basic infrastrcuture in place. Infrastructure includes no-frills bank account when Ram got his UID number. We also expect banking system to incrporate UID number in their system and complete interbank transfer using UID #.As his attendance data is processed, throug NREGA scheme, weekly payment will be directly deposited through interbank system to his bank account. If there is a mobile phone number tied to his UID #, he will be notified of the deposit.More importantly, usign his biometric, he can withdraw money through local bank representatives in the village.Entire process will be near instantenous and without any intermediate agents.

    • 10. Architecture Principles
      • Open standards to ensure interoperability.
      No vendor lock-in across the system
      Use of open-source technologies wherever prudent
      Multi-Platform Support – Linux, Microsoft
      10
    • 11. Arch/Design Choices
      SEDA (Staged Event Driven Architecture) allows smarter failure handling
      Fully distributed compute platform
      Highly asynchronous using a high speed messaging layer
      Data sharded across RDBMS and DFS over distributed platform

    • 12. Fingerprints : concepts and principles
      • Fingerprints are composed of ridges and valleys
      • 13. Ridges ending and bifurcations are creating some
      characteristics known as minutiae
      3 levels used for the biometric engine:
      • Level 1: ridge flow  classification
      • 14. Orientation, pattern, focal areas (Core, delta), …
      • 15. Level 2: ridge path  matching
      • 16. Features vectors (Minutiae)
      • 17. Ridge ending, bifurcation…
      • 18. Level 3: ridge features  Verification / Future matching
      • 19. Pores, ridges shapes, scars …
    • Iris: concepts and principles
      • Iris is the colored part of the eye
      • 20. Iris is made of colored tubes
      • 21. Iris contains a biometric pattern
      • 22. Rings, furrows, freckles and the corona
      • 23. Features and their location
      3 steps for the biometric engine:
      • Image is filtered to remove noise and reflexion
      • 24. The border of the iris is searched
      • 25. Apply Gabor transformation
