Abstract

The present invention discloses a method and apparatus for improving fingerprint recognition performance, and a mobile terminal. The method comprises: monitoring an operating state of a test terminal; receiving a plurality of test fingerprint images, and selecting a fingerprint image meeting a preset condition from the plurality of test fingerprint images according to the operating state of the test terminal; matching the fingerprint image with a preset fingerprint module to obtain a matching score of the fingerprint image; and according to the matching score, setting a matching threshold used for determining whether fingerprint recognition is successful. According to the method and apparatus for improving fingerprint recognition performance,and the mobile terminal provided by embodiments of the present invention, the operating state of the test terminal is monitored; the fingerprint image meeting the preset condition is selected from the plurality of test fingerprint images according to the operating state of the test terminal; the fingerprint image is matched with the preset fingerprint module to obtain the matching score of the fingerprint image; and the matching threshold is set according to the matching score, so that false acceptance rate is effectively reduced without any need of adding a hardware cost.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a method, device and mobile terminal for improving fingerprint identification performance. Background technique [0002] With the advancement of technology, smart mobile terminals have become one of the essential tools in people's lives. Adding fingerprint identification technology to smart mobile terminals has become a mainstream technical solution. Fingerprint recognition technology can not only be applied to functions such as unlocking and waking up of mobile terminals, but also an important part of mobile payment. Therefore, higher requirements are put forward for the security of fingerprint recognition technology. FAR (FalseAcceptRate, False Acceptance Rate) is one of the indicators to measure the security of fingerprint identification technology, which refers to the error probability of accepting different fingerprints as the same fingerprint.
