Fingerprint identification method and apparatus thereof

Abstract

Embodiments of the invention disclose a fingerprint identification method and an apparatus thereof. The method and the apparatus are used for increasing a fingerprint identification rate. The method comprises the following steps of acquiring first fingerprint information collected by a collector by a processor and determining whether the first fingerprint information matches with stored template fingerprint information; if the first fingerprint information does not match with the stored template fingerprint information, acquiring second fingerprint information collected by the collector, merging the second fingerprint information and the first fingerprint information to form third fingerprint information, and then determining whether the third fingerprint information matches with the template fingerprint information; if the third fingerprint information matches with the template fingerprint information, determining that fingerprint identification is successful. In the scheme, the fingerprint information collected at different moments during one acquisition process is superposed and then the information matches with the template fingerprint information so that the fingerprint identification rate can be increased.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to a fingerprint identification method and device. Background technique [0002] Fingerprint identification refers to identification by comparing the detailed feature points of different fingerprints. Starting from iPhone5s, mobile phone fingerprint recognition has attracted more and more attention, and more and more smartphones support fingerprint recognition, which is mainly used in two application scenarios of fingerprint unlocking and fingerprint payment. [0003] As the mobile phone becomes thinner and the fingerprint recognition module becomes smaller and smaller, the fingerprint information recorded at one time is limited. During the fingerprint registration, the user may press the same fingerprint area repeatedly, resulting in limited fingerprint information saved at the end of the final registration.

Problems solved by technology

[0003] As the mobile phone becomes thinner and the fingerprint identification module becomes smaller and smaller, the fingerprint information entered at one time is limited. During the fingerprint entry, the user may press the same fingerprint area repeatedly, resulting in limited fingerprint information saved at the end of the final entry.

[0004] In the prior art, in the process of fingerprint recognition, only one fingerprint information is collected for one recognition, and if the fingerprint information collected once deviates from the input area, the fingerprint recognition will fail, thus affecting the fingerprint recognition rate
