• Touchless Fingerprint Recognition

1. Motivation

  • Touch-based fingerprint Sensors have several problems by user's contact
  • Inconsistent contact
  • Skin condition changes
  • Latent problems

2. Touchless Sensor

  • System structure
  • Advantages
    • Capturing consistent image
    • Robust to skin conditions and deformation
  • Image Comparison
  • Research issue in Touchless fingerprint recognition
    • Expand effective region for registration
    • Capturing 5 fingerpritnt at once

3. Applications

  • Foreigner registration system in border controls & Latent problem
  • Person identification system for requiring high security & Latent problem
  • Multimodal biometric system & Latent problem
