  1. Middleware: Getting Between Biometric Readers and Template Transfer/Storage Mira LaCousCTO, VP Technology and Development BIO-key International, Inc. 651-687-0414mlacous@bio-key.com

  2. Abstract • A crucial factor in the acceptance of biometrics is getting information and templates from biometric readers into a usable format for storage and comparison against a database. "Middleware" solutions play a major role in streamlining this information for use with other biometric templates and solutions.

  3. Agenda • Purpose of Middleware with Biometrics. • What does Middleware Really Do? • User Interface • Application Interfaces • Security • Logic Control • Communications • Storage / Retrieval • Biometrics • Thoughts on Standards.

  4. Purpose of Middleware • Users interacting with complex systems. • Managing the overall process. • A case example…

  5. What does Middleware Do? • Provide essential functions: • User Interface • Application Interfaces • Security • Logic Control • Communications • Storage / Retrieval • We’ll focus on Biometric Authentications.

  6. The Architecture

  7. User Interface Requirements • User interaction and prompting. • User training and guidance. • Error and Exception handling. • Cool look and feel… it is a ‘new’ technology.

  8. API Requirements • Must be flexible for various systems. • Provide the key functionality of: • Administration • Enrollment • Authentication • Reports and Logs • May conform to standards, like BioAPI.

  9. Security Requirements • Examine all forms of spoofing/hacking. • Protect templates and models. • Prohibit replay and other attacks. • Preserve privacy. • Stop identity theft or use.

  10. Logic Control Requirements • Must make decisions at various levels. • Determine flow and control of authentication. • User Interaction • Security handling • Retry / Fail • Ultimately the decision for access / denial.

  11. Communications Requirements • Handles the transport of data and control. • Issues of Firewalls must be considered. • Consider standards: • TCP/IP & HTTP • 802.11b & Blue Tooth • USB & USB2 & Firewire • and many, many more • Again, must fit various needs.

  12. Storage Requirements • Centralized or Distributed. • Manages significant data for Biometrics. • Support Verification or Identification. • Suitable for various applications. • Meets standards and open… yet secure. • Cost effective…

  13. Now, the Biometric • Accuracy is required • Low False Accepts (major security issue) • Low False Rejects (piss off factor) • Low Failure to Enroll (missing populations) • Accessibility • Must be easy to use • Non-intrusive • Intuitive operation, when possible • Cost effective

  14. Standards • Each are can have a standard… • Templates (CBEFF, NIST, etc) • APIs (BioAPI, BAPI, HAAPI, etc) • Security (FIPS, X.509, CDSA, IPSEC, etc) • Storage (M1, Relational, ODBC, etc) • Industry (AAMVA, HIPAA, LDAP, Novell, etc) • Can fall to lowest common denominator. • Costs, advantages, requirements must all be weighed and examined.

  15. Is it Magic? • With the right components and structure, anything is possible. • There are many ways to the solution…
