PDA Biometric Integration

Daniel Dougherty

NSF REU at U.Va

Summer 2005


Program goals

Program Goals

  • Enable Privaris fingerprint scanner login for Web portal

  • Enable PDA login for Web portal using Biometric Interface


Problems faced privaris scanner

Problems faced: Privaris Scanner

  • How to interface with device

  • How to write programs for device

  • How to store information on device

  • How to access information once stored

  • How to interface with existing web portal


Interfacing with device

Interfacing with Device

  • Bluetooth adapter problems

  • Unable to successfully communicate with device


Results

Results?

  • How to write programs for device

  • How to store information on device

  • How to access information once stored

  • How to interface with existing web portal


Problems faced pda interface

Problems Faced: PDA Interface

  • How to write programs and web services in .NET

  • How to write and compile programs for PDA

  • How to use API for Biometric scanner

  • How to interface with existing web portal


Design options

Design Options

  • Storage of template (local or database)

    • Local File: Faster processing of templates

      (Better usability)

    • Database: Can’t send false acceptance

      (Better security)


Design options1

Design Options

  • Web service or client-side application

    • Service:

      • No implementation on local device

      • Server-side processing, less resource consumption

    • Client-Side:

      • No need to send new template across network


Design problems

Design Problems

  • Web Service:

    • BioAPI library failure

    • Bugs in Desktop portal interface

  • Client-side:

    • .NET libraries now limited

      • Can’t allocate memory for templates

      • Can’t launch external programs (Browser)

      • Attempted work-around with standard libraries


Results1

Results?

  • Substantial progress

  • Partial completion of client-side application

  • Still work left to enable PDA Biometric login


Possible future work

Possible Future Work

  • Access over wireless network

    • Ran across some issues with web services on the wireless network early on, but was unable to pursue these issues further due to time constraints

  • Encryption of information transferred over wireless network to/from PDA

  • Develop a PDA-specific version of web portal with smaller, mainly text based interface


  • Login
