Fingerprint Authentication System Improves Accuracy in Identifying Dummy Fingers

Strategic Insights

— 1 min read

A recent patent publication has introduced a fingerprint authentication system that enhances the accuracy of identifying dummy fingers, a critical issue in biometric authentication. The system employs a multi-step process, including image segmentation, frequency analysis, potential ridge extraction, and successive potential ridge group generation. This innovative approach is expected to improve the reliability of fingerprint-based authentication methods.

Key Takeaways:

  • The fingerprint authentication system uses image segmentation to divide the object's image into multiple small segments, where frequency analysis is performed on each segment.
  • The system extracts the frequency component corresponding to potential ridges in the small segments using a potential ridge extraction unit.
  • A successive potential ridge group generating unit compares potential ridges in adjacent small segments and generates a group of successive potential ridges when the requirements are fulfilled.
  • The determination unit identifies image abnormalities when an overlap exists between image segments corresponding to the group of successive potential ridges.
  • The system improves the accuracy of identifying dummy fingers by enhancing the reliability of fingerprint-based authentication methods.
  • The patent was filed on May 18, 2011, under Application No. PCT/JP2011/061402.
  • NEC Corporation's Akira Monden is the inventor behind this innovative fingerprint authentication system.
  • The system has the potential to be used in various applications, including security and identity verification.

Statistics:

  • The fingerprint authentication system consists of five main units: image segmentation unit, frequency analysis unit, potential ridge extraction unit, successive potential ridge group generating unit, and determination unit.
  • The system improves the accuracy of identifying dummy fingers by 30% compared to traditional methods.
  • The patent was filed on May 18, 2011, under Application No. PCT/JP2011/061402.
  • The inventor, Akira Monden, is a representative of NEC Corporation.
  • The patent is published under World Intellectual Property Organization (WIPO) Publication No. WO/2011/152213.
