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

The mobile terminals described in the embodiments of the present invention may include smart phones, tablet computers, PDAs, notebook computers, mobile Internet devices (MID, Mobile Internet Devices), wearable devices, etc. The above are only examples, not exhaustive, including but Not limited to the above mobile terminal, the mobile terminal in the embodiment of the present invention is installed with an Android (Android) operating system.

It should be noted that the mobile terminal in the embodiment of the present invention is provided with a fingerprint identification module, which is used for collecting fingerprint images. The embodiments of the present invention are mainly applied to a mobile terminal in a black screen state, that is, to perform a fingerprint unlocking operation on the mobile terminal in this state.

Optionally, the mobile terminal can adopt the characteristics of self-luminous screens such as Organic Light-Emitting Diode (OLED) screens and Incell screens. Because the screen does not require additional light sources, after the screen is powered on, if the backlight value is not set. , you can also keep the screen in a completely black state without lighting.

It should be noted that the embodiments of the present invention are only applicable to mobile terminals installed with the Android operating system. The fingerprint TA is a trusted application in the applications supported by a secure operating system corresponding to a trusted execution environment (Trust Execution Environment, TEE) of the mobile terminal. TEE provides a secure execution environment for trusted applications TA, and also protects the confidentiality, integrity and access rights of TA resources and data. In order to ensure the root of trust of the TEE itself, the TEE must be authenticated and isolated from the Android operating system during the secure boot process. In TEE, each TA is independent of each other and cannot access each other without authorization. The fingerprint identification module may be disposed on the front, back or side of the mobile terminal, and the embodiment of the present invention does not uniquely limit the specific composition and position of the fingerprint identification module.

Please refer to FIG. 1 , which is a schematic flowchart of a first embodiment of a fingerprint unlocking method according to an embodiment of the present invention. The fingerprint unlocking method described in this embodiment includes the following steps:

101. If the mobile terminal is in a black screen state, collect a fingerprint image when the fingerprint identification module of the mobile terminal is touched.

Wherein, the mobile terminal is in a black screen state. In this state, the fingerprint recognition module of the mobile terminal can be used to wait for a fingerprint image to be collected. When the fingerprint recognition module of the mobile terminal is touched, the fingerprint recognition module can be awakened, and the The fingerprint recognition module collects fingerprint images.

102. Perform a fingerprint authentication operation on the fingerprint image.

Wherein, a preset fingerprint template is pre-stored in the mobile terminal in the embodiment of the present invention, and the preset fingerprint template is previously entered by the user before executing the embodiment of the present invention. The fingerprint authentication operation means that the mobile terminal matches the fingerprint image with the preset fingerprint template. When the fingerprint image and the preset fingerprint template are successfully matched, the authentication result of the fingerprint authentication operation is that the authentication is successful. When the matching fails, the authentication result of the fingerprint authentication operation is authentication failure.

103. During the process of performing the fingerprint authentication operation, perform a wake-up operation on the screen of the mobile terminal, but do not light the screen.

The above steps 102 and 103 can be considered as two parallel processes, that is, one thread performs the step of performing the fingerprint authentication operation on the fingerprint image, and the other thread performs the wake-up operation on the screen of the mobile terminal, but does not light up all the steps described on the screen. Alternatively, one process performs the step of performing a fingerprint authentication operation on the fingerprint image, and another process performs the step of performing a wake-up operation on the screen of the mobile terminal without lighting the screen.

Optionally, step 103 is performed during the process of performing step 102, that is, after step 102 is started to be performed, step 103 is started to be performed at a certain moment before it ends.

Optionally, the above-mentioned wake-up operation on the screen of the mobile terminal may be a power-on operation on the screen, but the screen of the mobile terminal is not turned on.

104. When the authentication result of the fingerprint authentication operation is that the authentication is successful, turn on the screen.

Optionally, after step 104, after the screen is turned on, unlocking can be performed. In step 104, how to light up the screen may include the following steps:

Set the backlight value and light the screen according to the backlight value. As for how to set the backlight value, you can first obtain the ambient brightness and ambient color temperature, obtain the backlight value corresponding to the ambient brightness and the ambient color temperature, and light up the screen according to the backlight value. In this way, the illuminated screen is suitable for the environment.

Optionally, when the authentication result of the fingerprint authentication operation is that the authentication is successful, the lock screen interface of the mobile terminal can be set to be transparent. , notify the fingerprint unlocking application (ie Keyguard) to perform the unlocking operation, which can be understood as: using one process to perform, informing the PMS to perform the bright-screen operation, and another process, informing the fingerprint unlocking application to perform the unlocking operation, or, it can be understood as: using a The thread executes, notifies the PMS to perform the bright screen operation, and another thread executes, notifies the fingerprint unlocking application to perform the unlocking operation. In the embodiment of the present invention, after the screen lock interface is set to be transparent, the screen brightening operation and the unlocking operation are performed at the same time, so the fingerprint unlocking efficiency can be improved. In practical applications, in the above embodiment of the present invention, since the unlocking operation process can be optimized to about 200ms, that is, the unlocking operation can be completed after 200ms after the transparent state. Therefore, the user does not have any bad influence. Users feel that the unlocking speed is very fast, which improves the user experience.

Optionally, after step 103, the following steps may also be included:

When the authentication result of the fingerprint authentication operation is that the authentication is successful, the screen remains black.

Optionally, in the above step 104, when the authentication result of the fingerprint authentication operation is that the authentication is successful, it is detected whether a pressing event for the fingerprint recognition module occurs, and when a pressing event for the fingerprint recognition module is detected. When an event occurs, the lighting of the screen is performed.

As mentioned in the above step 101, the fingerprint recognition module is only touched, and the touch may be just by mistake. Therefore, a pressing event can be set. If the mobile terminal detects the pressing event, it can be considered that the fingerprint recognition module is not mistakenly touched. .

Further optionally, the above-mentioned detection of whether a pressing event for the fingerprint identification module occurs may include the following steps:

Detect whether the touch strength of the touch is increasing within a specified time period, and whether the maximum touch strength of the touch is greater than a preset threshold, when the touch strength is increasing and the maximum touch strength of the touch is greater than the preset threshold. When the threshold is set, it is determined that a pressing event for the fingerprint recognition module has occurred.

The above specified time period can be set by the user or the system defaults, for example, the length of time between when the object touches the fingerprint recognition module and when the object leaves the fingerprint recognition module, or, considering that the fingerprint recognition may be touched for a long time, Therefore, the preset time period when the object touches the fingerprint recognition module can be defined as a specified time period. In addition, the above-mentioned preset threshold can be set by the user or the system defaults. The mobile terminal can detect whether the touch force of touching the fingerprint recognition module within a specified time period is increasing, and whether the maximum touch force of the touch is greater than a preset threshold, and the touch force of touching the fingerprint recognition module within the specified time period is increasing. , and when the maximum touch force of the touch is greater than the preset threshold, it is considered that a pressing event for the fingerprint recognition module has occurred. Of course, if the touch force of touching the fingerprint recognition module does not show an increasing trend within the specified time period, or when the maximum touch force of the touch is less than or equal to the preset threshold, it is considered that no pressing event for the fingerprint recognition module has occurred.

Further optionally, after the above-mentioned detection of whether a pressing event for the fingerprint identification module occurs, the following steps may also be included:

When no pressing event for the fingerprint identification module is detected, the screen is powered off again.

Wherein, in the process of the user touching the fingerprint identification module, if the mobile terminal does not detect a pressing event for the fingerprint identification module, it can be considered that the touch is a false touch, so that the screen can be disconnected again. When the pressing event of the fingerprint recognition module is detected, the screen brightening operation can be performed. In this way, the fingerprint recognition operation can be performed in advance by using the time difference between the user touching the fingerprint recognition module and the pressing event, so as to speed up the unlocking speed of the black screen.

Further optionally, after the above-mentioned detection of whether a pressing event for the fingerprint identification module occurs, the following steps may also be included:

When no pressing event for the fingerprint identification module is detected, the authentication result of the fingerprint authentication operation is discarded.

In the process of the user touching the fingerprint identification module, if the mobile terminal does not detect a pressing event for the fingerprint identification module, it can be considered that the touch is a false touch, and the authentication result of the fingerprint authentication operation can be discarded. When the pressing event of the fingerprint recognition module is detected, the screen-on operation can be performed. In this way, the time difference between the user touching the fingerprint recognition module and the pressing event can be used to perform the fingerprint recognition operation and the screen enabling in advance. When the event occurs, turn on the screen again to speed up the unlocking speed of the black screen.

It can be seen that, according to the embodiment of the present invention, when the mobile terminal is in a black screen state, when the fingerprint recognition module of the mobile terminal is touched, a fingerprint image is collected, and a fingerprint authentication operation is performed on the fingerprint image. , perform a wake-up operation on the screen of the mobile terminal, but do not light up the screen, and light up the screen when the authentication result of the fingerprint authentication operation is that the authentication is successful. In this way, in the process of performing the fingerprint authentication operation, the screen can be woken up in advance, that is, the fingerprint authentication operation and the lighting of the screen can be performed in parallel, and the fingerprint unlocking efficiency is improved.

Consistent with the above, please refer to FIG. 2 , which is a schematic flowchart of a second embodiment of a fingerprint unlocking method provided by an embodiment of the present invention. The fingerprint unlocking method described in this embodiment includes the following steps:

201. If the mobile terminal is in a black screen state, collect a fingerprint image when a fingerprint identification module of the mobile terminal is touched.

202. Perform a fingerprint authentication operation on the fingerprint image.

203. During the process of performing the fingerprint authentication operation, perform a power-on operation on the screen of the mobile terminal, but do not light the screen.

204. When the authentication result of the fingerprint authentication operation is that the authentication is successful, set a backlight value, and light the screen according to the backlight value.

Optionally, the above-mentioned setting of the backlight value may include the following steps:

The setting of the backlight value is performed when the time interval from the power-on operation is greater than a preset time length.

Wherein, the above-mentioned preset time length can be set by the user or the system defaults. In this way, the backlight value can be set at an appropriate time, which can not only improve the fingerprint unlocking efficiency, but also reduce the power consumption of the mobile terminal.

It should be noted that, under normal circumstances, power-on of the screen is a time-consuming process, which involves hardware power-on, register initialization and other steps, which often take 200-300ms, and the screen setting backlight itself takes less time. The essence is to write a value to the register, and then the screen can light up the backlight line by line, which generally takes less than 50ms. In the embodiment of the present invention, the process of lighting the screen under normal circumstances is divided into two major stages: powering on the screen (see above step 203 ), setting the backlight value (see above step 204 ), and letting the mobile terminal perform the The screen powers up. Therefore, based on the above description, the time-consuming but imperceptible screen power-on part can be completed in advance, and the backlight value can be set at an appropriate time. How to find a suitable logic? Specifically, when implementing, first set a logic that can prevent the setting of the backlight to the screen, Blocker, in this embodiment of the present invention, the Blocker is a pre-set logic that can prevent the setting of the backlight to the screen, that is, if the Blocker exists , the backlight cannot be set after the screen is lit. If the Blocker is released, the backlight will be set immediately, and then the Blocker can be used to realize the parallel bright screen of the fingerprint. It can be understood that Blocker can be understood as a timing operation.

Optionally, in the process of executing step 201, if the fingerprint recognition module of the mobile terminal is touched, it can request to brighten the screen, the TA can collect the fingerprint image, and at the same time, it can send a bright screen request to the Fingerprint Service. After receiving the screen bright request, check whether the current behavior is fingerprint bright screen. When the current behavior is fingerprint bright screen, set the Blocker and wait for the Blocker. After the Blocker has waited for a preset length of time, the Blocker is released, so you can Set the backlight value, and then light the screen according to the backlight value.

Optionally, in the process of implementing the embodiment of the present invention, if the fingerprint authentication operation has been completed, and the Blocker has not ended at this time, the PMS may directly notify the setting of the backlight value, cancel the Blocker, and set the backlight value, and then, according to the backlight value. Light up the screen.

It can be seen that, according to the embodiment of the present invention, when the mobile terminal is in a black screen state, when the fingerprint recognition module of the mobile terminal is touched, a fingerprint image is collected, and a fingerprint authentication operation is performed on the fingerprint image. , the screen of the mobile terminal is powered on, but the screen is not turned on. When the authentication result of the fingerprint authentication operation is that the authentication is successful, the backlight value is set, and the screen is lit according to the backlight value. In this way, in the process of performing the fingerprint authentication operation, the screen can be powered on in advance, that is, the fingerprint authentication operation and the lighting of the screen can be performed in parallel, and the fingerprint unlocking efficiency is improved.
