• Fingerprint Recognition for Small Fingerprint Sensor

* Objective

  • Highly accurate fingerprint matching using a small-sized fingerprint sensor in mobile environments

* Issue

  • Acquisition of full fingerprint in enrollment process : fingerprint image selection or merging
  • Various feature extraction for accurate matching of small fingerprint images
    : extraction of minutiae, ridge flow, ridge frequency, micro-textures, etc.
  • Matching based on fusion of the multiple feature sets : feature-level fusion, score-level fusion, etc

* Flow chart

  • fingerprint enrollment

  • fingerprint matching

* Application

  • Phone unlocking : Protecting private data in mobile devices
  • Authentication for E-commerce applications
