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.
Claims20
A method for biometric authentication of a user comprising the steps of:
- a) providing:
- a mobile device comprising a camera and a screen;
- and
- a database;
- b) superimposing on the screen an overlay of a finger over a real-time image as currently seen through the camera;
- c) capturing with the camera an image of a fingerprint of the user;
- d) comparing the captured image with an authenticated fingerprint image that is stored in the database;
- and
- e) returning a positive result if the compared images match.
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.
A biometric authentication system comprising:
- a mobile device comprising a CCD or CMOS camera and a screen;
- and
- a database;
- wherein 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.
