Problems solved by technology

However, due to hardware space or cost constraints, the size of the fingerprint capture window may be limited to 9mm x 4mm or possibly smaller
These limitations can lead to higher false rejection or false acceptance rates in the enrollment and verification of the user's fingerprint, which can adversely affect the user experience of the device

Abstract

Embodiments of apparatus, computer program product, and method for verifying fingerprint images are disclosed. In one embodiment, a method of verifying fingerprint images includes receiving an inquiry fingerprint image of a user, identifying pattern characteristics of the inquiry fingerprint image, identifying minutiae characteristics of the inquiry fingerprint image, determining a weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image, where 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 verifying 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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of two applications: U.S. Application Serial No. 14 / 941,273, "Fingerprint Verification System," filed November 13, 2015, which claims U.S. Provisional Application No. 62 / 126,127, "Fingerprint Verification System," and U.S. Provisional Application No. 62 / 233,263, "Fingerprint Verification System," filed September 25, 2015. The aforementioned US applications are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to the field of computer security. In particular, the present invention relates to devices, computer program products and methods for authenticating fingerprint images. Background technique [0004] The use of fingerprint authentication access systems instead of passwords or PINs to control user access to devices is known in the smartphone industry or in the computer industry. However, due to hardware space or cost con...
