Problems solved by technology

[0004] However, due to the limited size of the fingerprint module of the mobile terminal, the fingerprint information that can be obtained is limited, and because the pre-saved fingerprint template is fixed, when the user unlocks the mobile terminal with the fingerprint, it often happens that the fingerprint cannot be entered once. In the case of successfully unlocking the mobile terminal, at this time, in order to unlock the mobile terminal, the user needs to enter his fingerprint multiple times, which leads to a very unsatisfactory fingerprint unlocking experience for the user

Abstract

The invention discloses a fingerprint identification method, a fingerprint template updating method, a fingerprint template updating device and a mobile terminal. The method comprises the following steps: acquiring a fingerprint image input by a user; comparing the fingerprint image with N fingerprint templates in a pre-stored fingerprint template group, and making a mobile terminal execute a corresponding target operation and further judging whether the matching value between the fingerprint image and the ith fingerprint template in the pre-stored fingerprint template group is greater than a second preset threshold if the matching value between the fingerprint image and the ith fingerprint template in the pre-stored fingerprint template group is greater than a first preset threshold, wherein the second preset threshold is greater than the first preset threshold; and generating a new fingerprint template according to the fingerprint image and adding the new fingerprint template to the fingerprint template group if the matching value is greater than the second preset threshold. According to the fingerprint identification method provided by the embodiment, the fingerprint templates are no longer fixed, and the fingerprint templates in the fingerprint template group are constantly improved and supplemented according to the fingerprint image used by the user in the subsequent using process.

Description

technical field [0001] The invention relates to the field of identification technology, in particular to a fingerprint identification method, a fingerprint template update method, a device and a mobile terminal. Background technique [0002] Fingerprint identification technology is a relatively mature biometric identification technology at present, and has become the standard configuration of flagship models of mainstream mobile terminal manufacturers. Fingerprint identification can not only be used for functions such as unlocking and waking up mobile terminals, but also an important part of mobile payment. Fingerprint for mobile payment, while convenient for users to pay, improves the security of mobile payment. [0003] At present, when a user uses fingerprint technology to unlock a mobile terminal or make mobile payment, the user needs to enter his fingerprint information into the mobile terminal in advance, and the mobile terminal will generate a fingerprint template acc...
