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.
The Mobile terminal described in the embodiment of the present invention may include a smart phone, a tablet computer, a palm computer, a notebook computer, a Mobile Internet device (MID, Mobile Internet Devices), a wearable device, and the like, which are merely examples and are not exhaustive, and include but are not limited to the above Mobile terminal.
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 a fingerprint image. The embodiment of the invention is mainly applied to the mobile terminal in the black screen state, namely, the fingerprint unlocking operation is carried out on the mobile terminal in the state.
Alternatively, the mobile terminal may adopt the characteristics of a self-luminous screen such as an Organic Light-Emitting Diode (OLED) screen or an inconel screen, because the screen does not need an additional Light source, and thus after the screen is powered on, if a backlight value is not set, the screen may be kept in a completely black state without Emitting Light.
When needing to be explained, the embodiment of the invention is only suitable for the mobile terminal provided with the Android operating system. The fingerprint TA is a trusted application in applications supported by a secure operating system corresponding to a Trusted Execution Environment (TEE) of the mobile terminal. The TEE provides a secure execution environment for the trusted application TA while also protecting the TA's resources and data confidentiality, integrity and access rights. To guarantee the root of trust of the TEE itself, the TEE is authenticated and isolated from the android operating system during secure boot. In TEE, each TA is independent of each other and cannot access each other without authorization. The fingerprint identification module can be arranged on the front side or the back side or the side of the mobile terminal, and the specific composition form and the position of the fingerprint identification module are not limited uniquely in the embodiment of the invention.
Fig. 1 is a flowchart illustrating a fingerprint unlocking method according to a first embodiment of the present invention. The fingerprint unlocking method described in the embodiment includes the following steps:
101. if the mobile terminal is in the black screen state, when the fingerprint identification module of the mobile terminal is touched, fingerprint images are collected.
Wherein, mobile terminal is in under the black screen state, and under this state, mobile terminal's fingerprint identification module can be used to wait for gathering the fingerprint image, and when this mobile terminal's fingerprint identification module was touched, fingerprint identification module can be awaken up to gather the fingerprint image by the fingerprint identification module.
102. And carrying out fingerprint authentication operation on the fingerprint image.
The mobile terminal in the embodiment of the invention stores a preset fingerprint template in advance, and the preset fingerprint template is input by a user in advance before the embodiment of the invention is executed. The fingerprint authentication operation is that the mobile terminal matches a fingerprint image with a preset fingerprint template, when the matching of the fingerprint image and the preset fingerprint template is successful, the authentication result of the fingerprint authentication operation is authentication success, and when the matching of the fingerprint image and the preset fingerprint template is failed, the authentication result of the fingerprint authentication operation is authentication failure.
103. And in the process of executing the fingerprint authentication operation, performing awakening operation on the screen of the mobile terminal, but not lighting the screen.
The steps 102 and 103 may 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 step of performing the wake-up operation on the screen of the mobile terminal, but does not light up the screen. Or, one process executes the step of performing the fingerprint authentication operation on the fingerprint image, and the other process executes the step of performing the wakeup operation on the screen of the mobile terminal but not lighting the screen.
Alternatively, step 103 is executed in the process of executing step 102, that is, after step 102 starts executing, step 103 starts executing at a certain time before it is not finished yet.
Optionally, the waking up the screen of the mobile terminal may be powering on the screen, but not lighting the screen of the mobile terminal.
104. And when the authentication result of the fingerprint authentication operation is successful, lightening the screen.
Optionally, after step 104, after the screen is lit, unlocking may be performed. How to light up the screen in step 104 may include the steps of:
setting a backlight value, and lighting up a screen according to the backlight value. As for how to set the backlight value, the ambient brightness and the ambient color temperature may be obtained first, the backlight value corresponding to the ambient brightness and the ambient color temperature is obtained, and the screen is lit up according to the backlight value, so that the lit up screen is suitable for the environment.
Optionally, when the authentication result of the fingerprint authentication operation is that the authentication is successful, the screen-locking interface of the mobile terminal may be set to be transparent, and after the completion, the Power Management Service (PMS) may be notified to perform the screen-lighting operation, and at the same time, the fingerprint unlocking application (i.e., Keyguard) is notified to perform the unlocking operation, which may be understood as being performed by using one process, notifying the PMS to perform the screen-lighting operation, and performing another process, notifying the fingerprint unlocking application to perform the unlocking operation, or may be understood as: and executing by adopting one thread to inform the PMS to execute the screen-lighting operation, and executing by adopting the other thread to inform the fingerprint unlocking application to execute the unlocking operation. In the embodiment of the invention, after the screen locking interface is set to be transparent, the screen lightening operation and the unlocking operation are simultaneously executed, so that the fingerprint unlocking efficiency can be improved. In practical application, in the embodiment of the present invention, the unlocking operation process can be optimized to be about 200ms, that is, the unlocking operation can be completed after the unlocking operation is performed for 200ms after the unlocking operation is performed in a transparent state, so that the user does not have any bad influence, but the user feels that the unlocking speed is fast, and the user experience is improved.
Optionally, after step 103, the following steps may be further included:
and when the authentication result of the fingerprint authentication operation is successful, keeping the black screen state.
Optionally, in the 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 identification module occurs, and when the pressing event for the fingerprint identification module is detected, the screen is lighted.
In the step 101, the fingerprint recognition module is touched only, and the touch may be a false touch, so that a pressing event may be set, and if the mobile terminal detects the pressing event, the fingerprint recognition module may be considered not to be the false touch.
Further optionally, the detecting whether the pressing event for the fingerprint identification module occurs may include:
whether the touch strength of the touch presents an increasing trend or not within a specified time period and whether the maximum touch strength of the touch is greater than a preset threshold value or not are detected, and when the touch strength presents an increasing trend and the maximum touch strength of the touch is greater than the preset threshold value, a pressing event aiming at the fingerprint identification module is determined to occur.
The specified time period may be set by the user or default to the system, for example, the time period from the time when the object touches the fingerprint identification module to the time when the object leaves the fingerprint identification module, or the preset time period from the time when the object touches the fingerprint identification module may be defined as the specified time period in consideration of the fact that the fingerprint identification may be touched for a long time. In addition, the preset threshold value can be set by the user or the default of the system. The mobile terminal can detect whether the touch force of the touch fingerprint identification module presents the increasing trend in the appointed time period or not, and whether the maximum touch force of the touch is greater than the preset threshold or not, the touch force of the touch fingerprint identification module presents the increasing trend in the appointed time period, and when the maximum touch force of the touch is greater than the preset threshold, the pressing event aiming at the fingerprint identification module is considered to occur. Certainly, the touch strength of touching the fingerprint identification module in the specified time period does not present an increasing trend, or when the maximum touch strength of the touch is less than or equal to the preset threshold, it is considered that the pressing event aiming at the fingerprint identification module does not occur.
Further optionally, after detecting whether the pressing event for the fingerprint identification module occurs, the method may further include the following steps:
when a pressing event for the fingerprint identification module is not detected, the screen is powered off again.
Wherein, at the in-process of user touch fingerprint identification module, if mobile terminal does not detect the press event to this fingerprint identification module, can regard this touch as the mistake and touch to, can make the screen disconnection again. When detecting the pressing event of fingerprint identification module, then executable bright screen operation, so, usable user touch fingerprint identification module and the time difference between the pressing event carry out the fingerprint identification operation in advance to accelerate black screen unblock speed.
Further optionally, after detecting whether the pressing event for the fingerprint identification module occurs, the method may further include the following steps:
and when the pressing event aiming at the fingerprint identification module is not detected, abandoning the authentication result of the fingerprint authentication operation.
Wherein, at the in-process of user touch fingerprint identification module, if mobile terminal does not detect the press event to this fingerprint identification module, can regard this touch as the mistake and touch, can abandon the authentication result of fingerprint authentication operation. When detecting the press event of fingerprint identification module, then executable bright screen operation, so, usable user touch fingerprint identification module and press the time difference between the event, carry out fingerprint identification operation and screen enable in advance, when having taken place to press the event, light the screen again to accelerate black screen unblock speed.
It can be seen that, according to the embodiment of the present invention, when the mobile terminal is in a black screen state and the fingerprint identification module of the mobile terminal is touched, the fingerprint image is collected and the fingerprint authentication operation is performed on the fingerprint image, in the process of performing the fingerprint authentication operation, the screen of the mobile terminal is wakened up but the screen is not lighted, and when the authentication result of the fingerprint authentication operation is that the authentication is successful, the screen is lighted. Therefore, the screen can be awakened in advance in the process of executing the fingerprint authentication operation, so that the fingerprint authentication operation and the screen lighting are performed in parallel, and the fingerprint unlocking efficiency is improved.
In accordance with the above, please refer to fig. 2, which is a flowchart illustrating a fingerprint unlocking method according to a second embodiment of the present invention. The fingerprint unlocking method described in the embodiment includes the following steps:
201. if the mobile terminal is in the black screen state, when the fingerprint identification module of the mobile terminal is touched, fingerprint images are collected.
202. And carrying out fingerprint authentication operation on the fingerprint image.
203. And in the process of executing the fingerprint authentication operation, carrying out power-on operation on the screen of the mobile terminal, but not lighting up the screen.
204. And when the authentication result of the fingerprint authentication operation is successful, setting a backlight value, and lightening the screen according to the backlight value.
Optionally, the setting the backlight value may include the following steps:
and when the time interval from the power-on operation is greater than a preset time length, executing the setting of the backlight value.
The preset time length can be set by the user or defaulted by the system. Therefore, the backlight value can be set at a proper time, the fingerprint unlocking efficiency can be improved, and the power consumption of the mobile terminal can be reduced.
It should be noted that, in general, screen power-on is a time-consuming process, wherein steps such as hardware power-on, register initialization and the like are involved, time consuming 200-300 ms is often required, and screen setting backlight itself is time consuming, which is essentially to write a value into a register, and then the screen lights the backlight row by row, and the time consuming is generally within 50 ms. In the embodiment of the invention, the process of lightening the screen under the normal condition is divided into two large stages: and powering on the screen (see the step 203), setting a backlight value (see the step 204), and enabling the mobile terminal to power on the screen in advance. Thus, based on the above description, the time-consuming but imperceptible portion of the screen power-up can be completed in advance and at an appropriate timing, the backlight value can be set. How to search for proper logic, specifically, in the implementation, a logic capable of preventing a screen from being provided with backlight is firstly set, namely, in the embodiment of the invention, a logic capable of preventing the screen from being provided with backlight is set in advance, namely, if the logic exists, the backlight cannot be set after the screen is lightened, if the logic is released, the backlight is set immediately, and then, the logic can be used for realizing the parallel screen lightening of the fingerprint. It is understood that Blocker can be understood as a timed operation.
Optionally, in the process of executing step 201, if the Fingerprint identification module of the mobile terminal is touched, the mobile terminal may request to illuminate a screen, the TA may collect a Fingerprint image, and meanwhile, may send a screen-illuminating request to a Fingerprint Service, after the Fingerprint Service receives the screen-illuminating request, detect whether the current behavior is Fingerprint-illuminating, and when the current behavior is Fingerprint-illuminating, set a Blocker, wait for the Blocker, after the Blocker waits for a preset time length, the Blocker is released, so a backlight value may be set, and then, the screen is illuminated according to the backlight value.
Optionally, in the process of executing the embodiment of the present invention, if the fingerprint authentication operation is completed and a Blocker is not yet completed at this time, the PMS may directly notify to set the backlight value, cancel the Blocker, set the backlight value, and further light up the screen according to the backlight value.
It can be seen that, according to the embodiment of the present invention, when the mobile terminal is in a black screen state and the fingerprint identification module of the mobile terminal is touched, the fingerprint image is collected and subjected to fingerprint authentication operation, in the process of executing the fingerprint authentication operation, the screen of the mobile terminal is powered on but the screen is not lighted, and when the authentication result of the fingerprint authentication operation is successful, the backlight value is set and the screen is lighted according to the backlight value. Therefore, the screen can be electrified in advance in the process of executing the fingerprint authentication operation, so that the fingerprint authentication operation and the screen lighting are performed in parallel, and the fingerprint unlocking efficiency is improved.

Referring to fig. 5, the handset includes: radio Frequency (RF) circuit 510, memory 520, input unit 530, display unit 540, sensor 550, audio circuit 560, Wireless Fidelity (Wi-Fi) module 570, processor 580, and power supply 590. Those skilled in the art will appreciate that the handset configuration shown in fig. 5 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
The following describes each component of the mobile phone in detail with reference to fig. 5:
The memory 520 may be used to store software programs and modules, and the processor 580 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 520. The memory 520 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 520 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit 530 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 530 may include a touch panel 531 and other input devices 532. The touch panel 531, also called a touch screen, can collect touch operations of a user on or near the touch panel 531 (for example, operations of the user on or near the touch panel 531 by using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 531 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 580, and can receive and execute commands sent by the processor 580. In addition, the touch panel 531 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 530 may include other input devices 532 in addition to the touch panel 531. In particular, other input devices 532 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit 540 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 540 may include a display panel 541, and optionally, the display panel 541 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 531 may cover the display panel 541, and when the touch panel 531 detects a touch operation on or near the touch panel 531, the touch panel is transmitted to the processor 580 to determine the type of the touch event, and then the processor 580 provides a corresponding visual output on the display panel 541 according to the type of the touch event. Although the touch panel 531 and the display panel 541 are shown as two separate components in fig. 5 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 531 and the display panel 541 may be integrated to implement the input and output functions of the mobile phone.
The handset may also include at least one sensor 550, such as a light sensor, motion sensor, and other sensors.
