Description

Unlocking control method and mobile terminal

Technical Field

The invention relates to the technical field of mobile terminals, in particular to an unlocking control method and a mobile terminal.

Background

The fingerprint is the line formed by the concave-convex skin on the finger abdomen at the tail end of the human finger, and the fingerprint of a person is combined with the heredity and the environment and is closely related to the health of the human body, so that the fingerprint is different among people, and the fingerprint repetition rate is extremely low and is about 150 parts per billion, so the fingerprint is called as a human body identity card. It is based on such characteristics of fingerprints that fingerprints are widely used as information for identity authentication.

For example, fingerprint identification technology has become the standard matching of the flagship model of the mainstream mobile terminal manufacturer. The fingerprint identification process comprises the following steps: extracting features, saving data and image matching. After the original fingerprint image of the human fingerprint is read by the fingerprint identification module, the characteristic point matching is carried out on the fingerprint image and a pre-stored registered fingerprint template; and unlocking after the matching is successful.

The speed of the unlocking time directly affects the efficiency of the user for using the equipment, and the speed of the unlocking time becomes a bright point of product competition of various manufacturers at present, and how to shorten the unlocking time so as to improve the unlocking efficiency is an important direction for the research of technicians in the field.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

In order to better understand the embodiments of the present invention, some basic concepts in the Android system are described below.

The Power Management Service (PMS) is used for controlling Power supply response of each module of the mobile terminal, such as controlling Power supply response of a display screen, when the system wakes up.

The fingerprint unlocking process of the mobile terminal in the screen-off state in the prior art is shown in fig. 1. The method comprises the steps that a user firstly presses a fingerprint identification module of the mobile terminal, an operating system of the mobile terminal generates a pressing interruption event, the mobile terminal wakes up a Power Management Service (PMS) of a system kernel after detecting the pressing interruption event, after waking up the PMS, a display screen power supply response is generated through the PMS, a display screen is lightened, a default main lock screen interface is loaded, the mobile terminal further wakes up the fingerprint identification module of the mobile terminal, the mobile terminal acquires fingerprint data of the user through the fingerprint identification module, the fingerprint data are identified, the main lock screen interface is unlocked after identification is successful, namely the main lock screen interface loaded on the display screen is removed, a system application interface is loaded at the same time, and the whole unlocking process is completed.

Based on the above-mentioned prior art, the following describes embodiments of the present invention in detail. An embodiment of the present invention provides a fingerprint unlocking control method, as shown in fig. 2, including:

s201, when the mobile terminal detects that the distance between the mobile terminal and the wearable device is smaller than a preset threshold value in first system time, awakening a Power Management Service (PMS) of the mobile terminal;

the mobile terminal is in a screen-off state, and the wearable device is an electronic device such as a smart watch, a smart bracelet and a smart ring which are worn on a wrist or a finger by a user. The preset threshold may be, for example, 5cm, 10cm, 20cm, or the like, and specifically, the distance between the mobile terminal and the wearable device when the user holds the mobile terminal to unlock the fingerprint may be stored, and an average value of a plurality of distances is counted as the preset threshold, or the preset threshold is set by the user.

In addition, in order to reduce the probability that the mobile terminal does not wake up the PMS due to the fact that the distance between the mobile terminal and the wearable device is smaller than the preset threshold value when the mobile terminal is detected in a non-fingerprint unlocking scene, judgment can be assisted according to parameters detected by sensors of the mobile terminal such as a photosensitive sensor, and if the ambient light intensity is detected to be lower than the preset light intensity threshold value, the mobile terminal does not actively start the PMS service and the like.

It can be understood that, the implementation manner of the mobile terminal detecting that the distance between the mobile terminal and the wearable device is smaller than the preset threshold at the first system time may be various, and the embodiment of the present invention is not limited uniquely.

In an embodiment, the implementation manner that the mobile terminal detects that the distance between the mobile terminal and the wearable device is smaller than the preset threshold at the first system time may be:

The effective communication distance of the NFC module is generally within 20cm, and in a scene where a user holds the mobile device to unlock a fingerprint, the distance between the mobile terminal and the wearable device is usually less than 20cm, so that a preset threshold value can be set to be 20 cm.

In another embodiment, the implementation manner that the mobile terminal detects that the distance between the mobile terminal and the wearable device is smaller than the preset threshold at the first system time may be:

In the process of determining the distance between the mobile terminal and the wearable device by means of phase sequence comparison, the preset signal sequence may be a wireless signal sequence that can be recognized by the mobile terminal, such as a designated sequence 0101010101 composed of 0 and 1.

S202, the mobile terminal detects touch operation of a fingerprint identification module aiming at the mobile terminal at a second system time, and fingerprint data are acquired, wherein the first system time is before the second system time;

in a specific implementation, the specific implementation manner of the mobile terminal acquiring the fingerprint data is as follows:

the mobile terminal passes through n2 bottom data values are obtained to n2 normal response electrodes of fingerprint identification module, n2 bottom data values are fingerprint data, the response electrode array of fingerprint identification module includes n1 unusual response electrodes with n2 normal response electrodes, n1, n2 are positive integer.

The interval duration between the first system time and the second system time is less than a preset interval duration; the preset interval duration may be, for example, 100s, 200s, 300s, or the like, that is, the mobile terminal may turn on the PMS periodically within a period in which the distance is less than the preset threshold, with the preset interval duration being a single continuous turn-on duration of the PMS, so that power loss caused by turning on the PMS may be reduced, and power may be saved to a certain extent.

Alternatively, the first and second electrodes may be,

the residual electric quantity of the mobile terminal is greater than or equal to a preset electric quantity; the preset power may be 20%, for example, that is, in a low power state, a user may set the mobile terminal not to actively start the PMS, so as to provide a more flexible setting scheme.

Alternatively, the first and second electrodes may be,

In addition, before the mobile terminal acquires the fingerprint data through the fingerprint identification module, the mobile terminal already wakes up the fingerprint identification module, specifically, the fingerprint identification module can be woken up at the first system time or the second system time, or the fingerprint identification module can be waken up all the time.

S203, the mobile terminal executes fingerprint identification processing aiming at the fingerprint data;

in a specific implementation, the performing fingerprint identification processing on the fingerprint data includes:

extracting feature points in the fingerprint image;

It is thus clear that mobile terminal is at the fingerprint identification in-process, through the unusual bottom data value of revising unusual response electrode collection for the bottom data value that the fingerprint identification module was gathered more accords with actual value, is favorable to promoting the rate of accuracy that fingerprint identification handled, thereby promotes fingerprint unblock security.

The implementation manner of determining the n1 reference bottom layer data values corresponding to the n1 abnormal sensing electrodes according to the n2 bottom layer data values collected by the n2 normal sensing electrodes of the fingerprint identification module can be diversified.

In an embodiment, the implementation of determining the n1 reference bottom layer data values corresponding to the n1 abnormal sensing electrodes according to the n2 bottom layer data values collected by the n2 normal sensing electrodes of the fingerprint identification module is as follows:

determining an average of the n2 underlying data values;

In another embodiment, the implementation manner of determining the n1 reference bottom layer data values corresponding to the n1 abnormal sensing electrodes according to the n2 bottom layer data values collected by the n2 normal sensing electrodes of the fingerprint identification module is as follows:

And S204, if the mobile terminal detects that the fingerprint identification processing result is successful, controlling the PMS to light up a display screen of the mobile terminal and loading a preset interface.

The mobile terminal can load a preset interface without loading a main lock screen interface.

Wherein, preset the interface and include:

It can be seen that, in the embodiment of the present invention, when detecting that the distance between the mobile terminal and the wearable device is smaller than the preset threshold, the mobile terminal wakes up the PMS service, and when the fingerprint identification processing is successful, the PMS is controlled to light up the display screen, and the preset interface is loaded.

It should be noted that, in the embodiment of the present invention, specific implementation manners of performing fingerprint identification processing on the fingerprint data may be various, and the embodiment of the present invention is not limited only. In addition, since the total time of the fingerprint identification processing procedure is generally within 300ms, and the operation time of waking up the PMS by the operating system of the mobile terminal generally needs about 400ms, that is, if the above fingerprint identification processing and the flow of waking up the PMS are executed serially, the mobile terminal needs to consume about 700ms of time, but the processing time of 400ms can be saved by the mobile terminal by adopting the processing method of waking up the PMS in advance described in the embodiment of the present invention. Therefore, the unlocking control method described in the embodiment of the invention can shorten the screen-on time of the mobile terminal in unlocking, and improve the user experience.

Optionally, in this embodiment of the present invention, when the mobile terminal detects that the distance between the mobile terminal and the wearable device is smaller than the preset threshold at the first system time, the following operations are further performed:

and the mobile terminal forbids a main lock screen interface loading service of the mobile terminal. Because the main lock screen interface loading service of the mobile terminal is forbidden in the first system time, the main lock screen interface does not need to be loaded after the subsequent fingerprint identification processing is successful.

Optionally, in the embodiment of the present invention, if the mobile terminal detects that the result of the fingerprint identification processing is an identification failure, the PMS is dormant, and the disabling of the loading service on the main lock screen interface is released.
