BIS4 SERVER ARCHITECTURE

The operational architecture shown below includes hot swap redundancy The second BIS4 server can be physically separated in another data centre anywhere in the world the implementation of the BIS4 server however is flexible and allows single server operation without redundancy.


Biometric identification server features BIS4

1. Four modes of biometric matching iris face, voice and fingerprint.
2. Identification ( recognition) & verification Enroll, update, delete, inactive
3. Compatible with DB2. oracle81, MS SQL
4. Administrator, operator and user ( with role based security)
5. Searches iris record at 1 million records per sec. running on dual Intel itanium
    processor
6. Impostor detection during enrollment (prevents multiple identities)
7. Searches against a wanted list
8. Defined user attributes ( eg wanted list flag )
9. Data base compactable with DB2 and oracle 8i
10. Every transaction is auditable
11. Multi threaded sockets interface
12. Transmits MACed, nonced and encrypted data (prevents replay)
13. Data encryption (database level3)
14. API security
15. Automatic storage of iris images (4KB) to assure no re-enrollment required for a
      future algorithm upgrade
16. Compatible with multiple biometric Biocam and other iris cameras
17. Supports three level of auditing
18. Optional personal information database
19. Operationally integrates with legacy or new personal information database
