This document discusses issues with biometrics technologies, specifically face recognition. It provides an overview of image issues including resolution, orientation, scale, lighting, image currency, and facial expressions. It also discusses privacy issues regarding video surveillance and personal data security. The document outlines the typical stages of identification/authentication technologies and notes some common places public assumes they are under video surveillance like stores, banks, and gas stations. It closes by stating biometrics will be widespread but users should be aware of its issues and limitations.

4. Today’s Agenda
Presentation Title Here

5. • After completing this lesson you will be able
to:
– have an overview knowledge about Biometric
Technologies image issues.
– have an overview knowledge about Biometric
Technologies privacy issues.

6.  It requires almost no interaction on behalf of the
user.
 It is accurate and allows for high enrolment and
verification rates.
 It can use your existing hardware infrastructure,
existing cameras and image capture Devices will
work with no problems

9. Issues with Face Recognition

10. • Resolution/Quality
• Orientation
• Scale
• Lighting
• Image Currency
– Physiologic changes due
to aging
• Face expression

14. • Video Surveillance or privacy?
• Personal data security

15. Video Surveillance, Biometrics, and Privacy
In what public places do you already
assume you are under video surveillance?
When you walk
into a building
from a parking
lot?

16. Video Surveillance, Biometrics, and Privacy
In what public places do you already
assume you are under video surveillance?
When you shop
at your favorite
store? Or go to
your bank?

17. Video Surveillance, Biometrics, and Privacy
In what public places do you already
assume you are under video surveillance?
When you buy
gas for your car?

18. Video Surveillance, Biometrics, and Privacy
Is it possible to use the technology to
track you? Or study your habits?
What about my information which is
captured?
……..

19. Video Surveillance, Biometrics, and Privacy
Biometrics technology are going to be every where,
but we need to be aware of its issues and
limitations:
• Image issues
• Personal data security
• ……

20. Next lesson…
- What about other issues like:
- Design
- Matching
- …
- This will be our next lesson.
