Fingerprint Verification System

A mobile device configured to verify fingerprint images, comprising:

• one or more sensors configured to receive an inquiry fingerprint image of a user;
• one or more processors that include a control logic, wherein the control logic includes
• logic configured to identify pattern characteristics of the inquiry fingerprint image;
• logic configured to identify minutiae characteristics of the inquiry fingerprint image;
• logic configured to determine a weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image, wherein the weighted combination comprises a pattern matching weight and a minutiae matching weight derived in accordance with a separation of a first empirical probability density function of genuine fingerprints from a second empirical probability density function of impostor fingerprints;
• and
• logic configured to verify the inquiry fingerprint image based on a set of fused scores computed using the weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image.

A non-transitory computer-readable storage medium including instructions stored thereon that, when executed, cause a mobile device to verify fingerprint images, comprising:

• instruction configured to receive an inquiry fingerprint image of a user;
• instruction configured to identify pattern characteristics of the inquiry fingerprint image;
• instruction configured to identify minutiae characteristics of the inquiry fingerprint image;
• instruction configured to determine a weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image, wherein the weighted combination comprises a pattern matching weight and a minutiae matching weight derived in accordance with a separation of a first empirical probability density function of genuine fingerprints from a second empirical probability density function of impostor fingerprints;
• and
• instruction configured to verify the inquiry fingerprint image based on a set of fused scores computed using the weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image.
