U3.15 Biometric Product Selection

U3.15 Biometric Product Selection

1. Reliability of the sensor

   • Sensors users touch require more maintenance
     • More subject to vandalisim
   • Sensors that dont require direct contact are usually more robust

2. Secuirty

   • In terms of errors
     • Best ERR
       • Iris Recognition has best ERR 1 in 1 mil
     • Lowest ERR
       • Speech and Signature
     • Medium ERR
       • Fingerprint

3. Performance

   • How fast can ID&A be confirmed.
     • Response times of less than 5 seconds for 1 to 1 match
   • Identification systems are slower due to comparing samples to the database

4. Cost

   • Retina & Hand geometry require specialist hardware
   • Speaker or face use off the shelf microphone/camera
   • More mature widely adopted tech is usually cheaper

5. User acceptance

   • Protection of privacy
   • Health risks / monitoring
   • Hygene
   • Bad associations IE fingerprint and crime

6. Life detection

   • Is the sample being taken from a live individual?

7. Unsuitable users

   • There will always be a certain level of unsuitable users
     • not able IE, nor arms, eyes
     • not willing, religious reasons

8. Size of the sensor

   • Large not good for mobile application
   • Chip sensors easily integrated
