Patent Images
1. A method for biometric authentication of a user comprising the steps of:
- a) providing;
a mobile device comprising a camera and a screen;
a database; and
a randomly-generated image that is unique to each user using the mobile device;
b) capturing with the camera an image of a fingerprint of the user;
c) extracting first significant geographical areas of the fingerprint image;
d) extracting second significant geographical areas of the randomly-generated image;
e) concatenating the first significant geographical areas with the second significant geographical areas to produce a concatenated string;
f) comparing the concatenated string with an authenticated concatenated string that is stored in the database; and
g) returning a positive result if the compared strings match.

Abstract
This disclosure is of a biometric authentication system and method. The system includes a mobile device having a camera and a screen, and a database. The system is programmed to superimpose on the screen an overlay of a finger over a real-time image seen by the camera, capture an image of a fingerprint of a user with the camera, compare the captured image with an authenticated fingerprint image that is stored in the database, and return a positive result if the compared images match.
