SYSTEMS AND METHODS FOR PERFORMING FINGERPRINT BASED USER AUTHENTICATION USING IMAGERY CAPTURED USING MOBILE DEVICES
First Claim
1. A method for performing fingerprint recognition, the method comprising:
- capturing, by a mobile device having a camera, a storage medium, instructions stored on the storage medium, and a processor configured by executing the instructions, images depicting a plurality of fingers of a subject;
detecting, with the processor using a finger detection algorithm, the plurality of fingers depicted in one or more of the images;
identifying, with the processor from one or more of the images according to a segmentation algorithm, a respective fingertip segment for each finger among the plurality of fingers;
extracting, with the processor for each finger, discriminatory features from the respective fingertip segment; and
generating a biometric identifier including the extracted discriminatory features;
storing the generated biometric identifier in the memory with the processor.

Abstract
Technologies are presented herein in support of a system and method for performing fingerprint recognition. Embodiments of the present invention concern a system and method for capturing a user'"'"'s biometric features and generating an identifier characterizing the user'"'"'s biometric features using a mobile device such as a smartphone. The biometric identifier is generated using imagery captured of a plurality of fingers of a user for the purposes of authenticating/identifying the user according to the captured biometrics and determining the user'"'"'s liveness. The present disclosure also describes additional techniques for preventing erroneous authentication caused by spoofing. In some examples, the anti-spoofing techniques may include capturing one or more images of a user'"'"'s fingers and analyzing the captured images for indications of liveness.
