Spoof Detection Using Localized Illumination for Biometric Authentication Systems - A simplified explanation of the abstract
This abstract first appeared for US patent application 18319200 titled 'Spoof Detection Using Localized Illumination for Biometric Authentication Systems
Simplified Explanation
- The patent application describes a biometric authentication system that uses a touch-sensitive display for user input. - The system includes a biometric authentication manager that can determine the shape of the user input and alter the luminosity and/or color of certain parts of the display. - This technique allows the system to create variable illumination patterns on the display, which can produce a reflection of the user's fingerprint. - The system then analyzes this fingerprint reflection to determine its authenticity and to detect spoof fingerprints. - The innovation aims to enhance the security of biometric authentication by using spatially, temporally, and/or chromatically variable illumination patterns.
Original Abstract Submitted
This document describes a biometric authentication system including a biometric authentication manager is configured to receive user input at a touch-sensitive display, determine a shape of the user input, and alter a luminosity and/or color of one or more portions of a region of the touch-sensitive display. Through such a technique, the biometric authentication manager can implement spatially, temporally, and/or chromatically variable illumination patterns to produce a fingerprint reflection, receive the fingerprint reflection, and then analyze the fingerprint reflection for authenticity and/or for liveness characteristics effective to detection spoof fingerprints.
