Abstract

Embodiments of the present invention provide a fingerprint identification method and a mobile terminal, wherein the method includes: acquiring humidity information and fingerprint information of the detection object; judging whether the acquired fingerprint information is consistent with the preset fingerprint information according to the acquired humidity information Information matches. The embodiments of the present invention can improve the accuracy of fingerprint identification.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fingerprint identification method and a mobile terminal. Background technique [0002] With the improvement of users' security awareness, it is more and more common for fingerprints to be used as the only password certificate to open mobile terminals. Therefore, the accuracy of fingerprint recognition is more and more concerned by users. At present, fingerprint recognition is to match the detected fingerprint with the fingerprint stored in the storage unit of the mobile terminal, and the user's finger will sweat or touch liquid, resulting in the fingerprint being recognized. An error occurred or could not be recognized. [0003] To sum up, the accuracy of fingerprint recognition is low when the object to be recognized has a certain humidity. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a fingerprint identificat...
