Problems solved by technology

In this way, when other objects (such as objects or other parts of the user) accidentally touch the fingerprint detection component, the mobile terminal will turn off the fingerprint unlocking function, resulting in the user being unable to use the fingerprint unlocking function.

Embodiment Construction

[0048] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0049] Embodiments of the present disclosure provide a method and device for unlocking. The method can be used in a terminal, where the terminal can be a terminal with a fingerprint unlocking function, such as a mobile terminal such as a mobile phone or a tablet computer. The terminal may include a fingerprint detection component, a processor and a memory. Among them, the fingerprint de...

Abstract

The invention relates to an unlocking method and device, and belongs to the technical field of fingerprint recognition. The method comprises the following steps: acquiring a detection signal detected by a fingerprint detection part; and determining a matching degree between the detection signal and a pre-stored reference fingerprint signal, executing unlocking processing when the matching degree is greater than a first preset matching degree threshold value, keeping a screen locking state and recording a fingerprint error event when the matching degree is smaller than the first preset matching degree threshold value and greater than a second preset matching degree threshold value, and ignoring the detection signal when the matching degree is smaller than the second preset matching degree threshold value. Through adoption of the unlocking method and device, the situation that a terminal turns off a fingerprint unlocking function due to error touch can be avoided.

Description

technical field [0001] The present disclosure relates to the technical field of fingerprint identification, in particular to a method and device for unlocking. Background technique [0002] With the development of mobile terminal technologies, mobile terminals are used more and more widely, and have become one of the most important tools in people's daily work and life. In the process of using the mobile terminal, in order to ensure the security of user information, a fingerprint unlocking function is set in the mobile terminal. Through the fingerprint unlocking function, the user can conveniently perform an unlocking operation on the mobile terminal. [0003] In practice, the fingerprint signal is generally detected by the fingerprint detection part in the mobile terminal. The user can touch the detection end of the fingerprint detection part with a finger, and the fingerprint detection part will detect the fingerprint signal. The mobile terminal can compare the detected f...
