What is Biometric Identification Technology?

• Uses biological characteristics to identify
  person
• Characteristics are unique
• Finger Prints, Voice, Iris
• Greater security, More convenient

How Does Voice Authentication Work?

• Captures physical characteristics of voice
• Points of Inflection
• Harmonic and Resonant Frequencies
• Compared to voiceprints in a database
• Finds match and
• grants clearance

What a Voiceprint Looks Like
5
Security

• Voice is one of least accurate biometrics
  Jackie Fenn, Gartner Inc.
• Background Noise
• Equipment Quality
• Day-to-Day Changes
• Sensitivity Threshold Settings
• Too Low Insecure

6
Practicality

• Easiest biometric method to integrate
• Telephone or Microphone
• Only biometric system with remote access
• Saves time and money

7
Current Use

• Systems range from 50 personal use to 50,000
  corporate use
• Useful for sensitive systems with many users,
  performing repetitive actions
• Currently 4.1 market share
• Law Enforcement
• Union Pacific Railroad

8
Future of Voice Authentication

• Industry wide standards must be adapted
• File Format
• Interface
• Will one day be used in
• Banks and Credit Cards
• Highly Regulated Industries
• High Level National Security
