Description

Technical Field

[0001] The present invention relates to the field of terminal technology, and in particular to a fingerprint entry method, device, mobile terminal and storage medium. Background Art

[0002] With the rapid development of fingerprint recognition technology and the rapid popularization of fingerprint sensors, almost all terminal devices are now equipped with various fingerprint sensors to realize various fingerprint recognition functions, such as terminal unlocking, secure payment, and identity verification based on fingerprint recognition. However, no matter what application scenario the fingerprint sensor is used in, in order to realize various functions of fingerprint recognition, the user needs to enter the fingerprint on the terminal in advance as the sample data for recognition, so that the subsequent unlocking, secure payment, and identity verification functions of the terminal can be realized.

[0003] In order to expand the application scenarios of fingerprint recognition and further improve the user experience, existing terminals often pre-install multiple (such as two) fingerprint modules on the terminal. Although setting up multiple fingerprint modules can bring many conveniences to users, such as users can directly set a startup fingerprint for a terminal application, terminals with multiple fingerprint modules are prone to the problem that users cannot successfully enter fingerprints during fingerprint entry due to the operation of other fingerprint modules. Summary of the invention

[0004] The main purpose of the present invention is to provide a fingerprint entry method, device, mobile terminal and storage medium, aiming to solve the technical problem that a terminal equipped with multiple fingerprint modules may easily cause the user to be unable to successfully enter the fingerprint during the fingerprint entry process due to the operation of other fingerprint modules.

[0005] After the fingerprint entry process of the terminal is resumed, detecting whether the fingerprint entry process contains a channel identifier of a fingerprint channel of the terminal;

[0006] When it is detected that the fingerprint recording process does not save the channel identifier, generating a fingerprint recording continuation instruction;

[0007] The fingerprint channel is switched according to the fingerprint continuation instruction, and fingerprint continuation is performed based on the switched fingerprint channel.

[0008] Optionally, after the fingerprint entry process of the terminal is resumed, the step of detecting whether the fingerprint entry process contains a channel identifier of a terminal fingerprint channel includes:

[0009] After the terminal is unlocked based on the unlocking fingerprint in the lock screen state, the fingerprint entry process corresponding to the fingerprint entry interface currently restored and displayed by the terminal is obtained;

[0010] It is detected whether a channel identifier for identifying a terminal fingerprint channel where the terminal fingerprint module is located is stored in the fingerprint entry process.

[0011] Optionally, before the step of generating a fingerprint continuation instruction when detecting that the fingerprint entry process does not save the channel identifier, the step includes:

[0012] If the channel identifier is saved in the fingerprint unlocking process of the terminal after the terminal is unlocked based on the unlocking fingerprint, it is determined that the channel identifier is not saved in the fingerprint entry process currently restored by the terminal.

[0013] Optionally, after the step of detecting that the fingerprint entry process does not save the channel identifier, the fingerprint entry method further includes:

[0014] The fingerprint entry interface currently restored and displayed by the terminal is redirected to the fingerprint entry selection interface, and the user is prompted to re-enter the fingerprint.

[0015] Optionally, the generated fingerprint continuation instruction carries the channel identifier.

[0016] The step of switching the fingerprint channel according to the fingerprint continuation instruction and continuing the fingerprint recording based on the switched fingerprint channel includes:

[0017] Acquire the channel identifier carried in the fingerprint continuation instruction, and switch the fingerprint channel of the terminal fingerprint module to the fingerprint entry process based on the channel identifier;

[0018] The fingerprint re-recorded by the user is acquired through the switched fingerprint channel, and the re-recorded fingerprint is stored.

[0019] Optionally, the fingerprint entry method further includes:

[0020] When a lock screen message broadcast by the terminal system is detected, the fingerprint entry interface currently displayed on the terminal is redirected to the fingerprint entry selection interface, and the user is prompted to re-enter the fingerprint after the terminal is unlocked.

[0021] Optionally, after the step of detecting whether the fingerprint entry process contains a channel identifier of a terminal fingerprint channel, the step further includes:

[0022] If it is detected that the fingerprint entry process stores the channel identifier, fingerprint continued recording is performed based on the fingerprint channel specified by the channel identifier.

[0023] In addition, to achieve the above-mentioned purpose, the present invention also provides a fingerprint entry device, the fingerprint entry device comprising:

[0024] An identification detection module, used for detecting whether the fingerprint entry process of the terminal contains a channel identification of the terminal fingerprint channel after the fingerprint entry process of the terminal is resumed;

[0025] An instruction generation module, used for generating a fingerprint continuation instruction when detecting that the fingerprint entry process does not save the channel identifier;

[0026] The first fingerprint continuation module is used to switch the fingerprint channel according to the fingerprint continuation instruction, and to continue fingerprint recording based on the switched fingerprint channel.

[0027] In addition, to achieve the above object, the present invention also provides a mobile terminal;

[0028] The mobile terminal comprises: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein:

[0029] When the computer program is executed by the processor, the steps of the fingerprint entry method described above are implemented.

[0030] In addition, to achieve the above-mentioned purpose, the present invention also provides a storage medium;

[0031] The storage medium stores a computer program, and when the computer program is executed by the processor, the steps of the fingerprint entry method described above are implemented.

[0032] The embodiments of the present invention propose a fingerprint entry method, device, mobile terminal and storage medium. After the fingerprint entry process of the terminal is restored, it is detected whether the fingerprint entry process contains a channel identifier of the terminal fingerprint channel; when it is detected that the fingerprint entry process does not save the channel identifier, a fingerprint continuation instruction is generated; the fingerprint channel is switched according to the fingerprint continuation instruction, and fingerprint continuation is performed based on the switched fingerprint channel.

[0033] The present invention detects whether a channel identifier for a terminal fingerprint channel in which a terminal fingerprint module is located is saved in the fingerprint entry process currently restored by the terminal during the fingerprint entry process between terminal unlocking and restoring the lock screen. If the terminal is unlocked based on the unlocking fingerprint and the channel identifier is saved in the fingerprint unlocking process, resulting in no channel identifier saved in the fingerprint entry process currently restored by the terminal, a fingerprint continuation instruction is generated that carries the channel identifier of the fingerprint channel in which the terminal fingerprint module is located when the terminal is designated to perform fingerprint entry. According to the channel identifier, the fingerprint channel of the terminal fingerprint module is switched and connected to the fingerprint entry process currently restored by the terminal, and the fingerprint re-recorded by the user is obtained based on the fingerprint channel after the switching connection, and the fingerprint re-recorded by the user is entered and stored.

[0034] The invention realizes that, after the terminal is unlocked based on the unlocking fingerprint, the fingerprint channel of the terminal fingerprint module has switched to the fingerprint unlocking process, and the fingerprint channel required for fingerprint entry is not connected to the fingerprint entry process restored after the terminal is unlocked, a fingerprint continuation instruction containing a channel identifier specifying the fingerprint channel required for the current fingerprint entry process is generated. After the instruction is detected, based on the channel identifier carried on the instruction, the fingerprint channel of the terminal fingerprint module connected to the fingerprint unlocking process is switched back to the fingerprint entry process currently restored by the terminal, and the fingerprint recorded by the user is re-entered and stored based on the fingerprint channel, so that, in the process of recording fingerprints, when the terminal with multiple fingerprint modules switches the fingerprint channel based on different unlocking fingerprints, after the terminal is unlocked and the fingerprint entry process is restored, the fingerprint channel is switched back to the restored fingerprint entry process, so that the user can continue to perform the fingerprint entry operation on the original fingerprint entry process restored by the terminal unlocking after the fingerprint entry process is interrupted by the terminal lock screen.

[0046] The following description will be made by taking a mobile terminal as an example, and those skilled in the art will appreciate that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present invention can also be applied to fixed-type terminals.

[0047] See also Figure 1 , which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present invention, the mobile terminal 100 may include: RF (Radio Frequency, radio frequency) unit 101, WiFi module 102, audio output unit 103, A / V (audio / video) input unit 104, sensor 105, display unit 106, user input unit 107, interface unit 108, memory 109, processor 110, and power supply 111 and other components. Those skilled in the art can understand that Figure 1 The structure of the mobile terminal shown in the figure does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0048] Combine the following Figure 1 The following is a detailed introduction to the various components of the mobile terminal:

[0049] The radio frequency unit 101 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving the downlink information of the base station, it is sent to the processor 110 for processing; in addition, the uplink data is sent to the base station. Generally, the radio frequency unit 101 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 101 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communication can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution) and TDD-LTE (Time Division Duplexing-Long Term Evolution), etc.

[0050] WiFi is a short-range wireless transmission technology. Mobile terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

[0051] The audio output unit 103 can convert the audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0052] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processor (GPU) 1041 and a microphone 1042, and the graphics processor 1041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 106. The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a telephone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0053] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can also be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0054] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0055] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Specifically, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Specifically, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, a function key (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, etc., which are not specifically limited here.

[0056] Furthermore, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of the touch event. Then, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited here.

[0057] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0058] The memory 109 can be used to store software programs and various data. The memory 109 can be a computer storage medium, and the memory 109 stores the fingerprint entry program of the present invention. The memory 109 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0059] The processor 110 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 109 and calling data stored in the memory 109, thereby monitoring the mobile terminal as a whole. For example, the processor 110 executes the fingerprint entry program in the memory 109 to implement the steps of each embodiment of the fingerprint entry method of the present invention.

[0060] The processor 110 may include one or more processing units; optionally, the processor 110 may integrate an application processor and a modem processor, wherein the application processor mainly processes an operating system, a user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the modem processor may not be integrated into the processor 110.

[0061] The mobile terminal 100 may further include a power supply 111 (such as a battery) for supplying power to various components. Optionally, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as managing charging, discharging, and power consumption management through the power management system.

[0062] although Figure 1 Not shown, the mobile terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0063] To facilitate understanding of the embodiments of the present invention, the communication network system on which the mobile terminal of the present invention is based is described below.

[0064] See also Figure 2 , Figure 2A communication network system architecture diagram is provided for an embodiment of the present invention. The communication network system is an LTE system of universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204, which are sequentially connected for communication.

[0065] Specifically, UE201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0066] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 , etc. Among them, eNodeB 2021 can be connected to other eNodeBs 2022 through a backhaul (eg, an X2 interface), and eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 can provide UE 201 with access to EPC 203 .

[0067] EPC203 may include MME (Mobility Management Entity) 2031, HSS (Home Subscriber Server) 2032, other MMEs 2033, SGW (Serving Gate Way) 2034, PGW (PDN Gate Way) 2035 and PCRF (Policy and Charging Rules Function) 2036, etc. Among them, MME2031 is a control node that processes signaling between UE201 and EPC203, and provides bearer and connection management. HSS2032 is used to provide some registers to manage functions such as home location register (not shown in the figure), and save some user-specific information such as service features and data rates. All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, which selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0068] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0069] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present invention is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems, etc., which are not limited here.

[0070] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present invention are proposed.

[0071] The present invention provides a fingerprint entry method, which comprises:

[0072] After the fingerprint entry process of the terminal is resumed, whether the fingerprint entry process contains the channel identifier of the terminal fingerprint channel is detected; when it is detected that the fingerprint entry process does not save the channel identifier, a fingerprint continuation instruction is generated; the fingerprint channel is switched according to the fingerprint continuation instruction, and fingerprint continuation is performed based on the switched fingerprint channel.

[0073] For details, please refer to Figure 3 , Figure 3 1 is a flow chart of the first embodiment of the fingerprint entry method of the present invention. In the first embodiment of the fingerprint entry method of the present invention, the fingerprint entry method includes:

[0074] Step S10: after the fingerprint entry process of the terminal is resumed, detecting whether the fingerprint entry process contains a channel identifier of the terminal fingerprint channel.

[0075] When the terminal unlocks the screen based on identifying the unlocking fingerprint, the terminal immediately resumes the fingerprint entry process that was running in the foreground when the screen was locked. After the fingerprint entry process is resumed, the terminal detects whether the fingerprint module that identified the terminal when performing fingerprint entry still has a channel identifier that is connected to the fingerprint channel.

[0076] Specifically, for example, in Figure 6In the application scenario shown, when the smart terminal based on the Android system is performing a fingerprint entry operation, the screen is locked because no instructions triggered by the user have been received for a long time. In the locked screen state, the smart terminal identifies and compares the unlocking fingerprint input by the user based on the fingerprint unlocking module, and after the current locked screen state is released, the fingerprint entry process that is running in the foreground when the smart terminal enters the locked screen state will be restored based on the onResume (callback) method and the fingerprint entry process will be displayed on the smart terminal screen. The fingerprint entry interface output by the fingerprint entry process when the smart terminal is locked will be displayed. After the fingerprint entry process is restored, it is detected whether the currently restored fingerprint entry process still has a channel identifier that indicates that the fingerprint module of the smart terminal has been connected to the fingerprint channel when the smart terminal is performing fingerprint entry.

[0077] Furthermore, step S10 includes:

[0078] Step S101, after the terminal is unlocked based on the unlocking fingerprint in the lock screen state, the fingerprint entry process corresponding to the fingerprint entry interface currently restored and displayed by the terminal is obtained.

[0079] When the terminal is in the locked screen state, after identifying the unlocking fingerprint input by the user and comparing the unlocking fingerprint sample data, it is determined that the unlocking fingerprint is correct and the current locked screen state of the terminal is released, the fingerprint entry interface corresponding to the terminal's current moment restored and displayed based on the callback method is obtained, and the fingerprint entry process that is running in the foreground of the terminal when the terminal is locked.

[0080] Specifically, for example, when the smart terminal is in the lock screen state, it identifies the unlocking fingerprint input by the user based on the fingerprint unlocking module, and compares the identified unlocking fingerprint with the stored unlocking fingerprint sample data, thereby determining that the unlocking fingerprint input by the user is correct and releasing the current lock screen state. Then, it detects the fingerprint entry process running in the foreground of the terminal when the smart terminal identified by the fingerprint entry interface that is restored and displayed based on the onResume method is in the lock screen.

[0081] Step S102, detecting whether a channel identifier identifying a terminal fingerprint channel where the terminal fingerprint module is located is stored in the fingerprint entry process.

[0082] When the terminal is unlocked based on the unlocking fingerprint and the currently restored terminal lock screen is obtained, after the fingerprint entry process is running in the terminal foreground, it is detected whether the currently restored fingerprint entry process still saves the fingerprint module that identified the terminal when the fingerprint was entered, and the channel identifier of the fingerprint channel that has been connected.

[0083] Specifically, for example, when the smart terminal is in the locked screen state, it releases the current locked screen state by identifying and comparing the unlocking fingerprint input by the user based on the fingerprint unlocking module, and obtains the fingerprint entry interface identified by the smart terminal that is restored and displayed based on the onResume method. When the smart terminal is locked, after the fingerprint entry process is running in the foreground of the terminal, it detects whether the channel identifier used to identify that the fingerprint module of the smart terminal is currently connected to the fingerprint channel is saved in the currently restored fingerprint entry process.

[0084] It should be noted that, in the various running processes based on fingerprint recognition and comparison of the smart terminal, the various running processes based on fingerprint recognition and comparison can only continue when the fingerprint module of the smart terminal has been connected to the fingerprint channel. For example, when the fingerprint unlocking module of the smart terminal is connected to the fingerprint channel, the smart terminal can run the recognition and comparison based on the unlocking fingerprint, thereby releasing the fingerprint unlocking process from the locked screen state; when the fingerprint entry module of the smart terminal is connected to the fingerprint channel, the smart terminal can run the fingerprint entry process; wherein, the fingerprint channel is a virtual or physical channel connecting the fingerprint module of the smart terminal and the fingerprint sample database on the smart terminal.

[0085] Step S20: When it is detected that the fingerprint entry process does not save the channel identifier, a fingerprint continuation instruction is generated.

[0086] If it is not detected that the fingerprint module used to identify the terminal for fingerprint entry is still saved in the currently restored fingerprint entry process and the channel identifier of the fingerprint channel has been connected, a fingerprint continuation instruction is generated to continue fingerprint entry based on the currently restored fingerprint entry process.

[0087] Specifically, for example, when the smart terminal unlocks the screen and obtains the fingerprint entry interface that is restored and displayed by the smart terminal based on the onResume method, the fingerprint entry process that is running in the foreground of the terminal when the smart terminal is locked is obtained, and it is further detected that the fingerprint entry process currently restored by the smart terminal does not contain a channel identifier for identifying that the fingerprint module of the smart terminal is currently connected to the fingerprint channel, a fingerprint continuation instruction based on the fingerprint entry process currently restored by the smart terminal is immediately generated to continue executing the fingerprint entry operation, and the fingerprint continuation instruction is sent to the driver layer of the smart terminal.

[0088] Furthermore, before step S20, the fingerprint entry method of the present invention further includes:

[0089] Step A: If the channel identifier is saved in the fingerprint unlocking process of the terminal after the terminal is unlocked based on the unlocking fingerprint, it is determined that the channel identifier is not saved in the fingerprint entry process currently restored by the terminal.

[0090] Specifically, for example, when a user performs a fingerprint entry operation based on a finger different from the unlocking fingerprint and before the smart terminal locks the screen, based on the fingerprint entry module of the smart terminal, when the user inputs the unlocking fingerprint on the fingerprint unlocking module of the smart terminal based on the finger where the unlocking fingerprint is located to release the lock screen state of the smart terminal, the smart terminal needs to switch the fingerprint channel connected to the fingerprint entry module to the fingerprint unlocking module during fingerprint entry because the fingerprints identified and collected during the fingerprint entry process and the fingerprint recognition and unlocking process are inconsistent. After the smart terminal completes the unlocking through fingerprint recognition and comparison, the fingerprint channel is still connected to the fingerprint unlocking module but not to the fingerprint entry module of the current fingerprint entry process restored based on the onResume method. That is, at this time, the channel identifier used to identify that the fingerprint module has been connected to the fingerprint channel is still saved in the fingerprint unlocking process of the current smart terminal. It can be determined that the channel identifier is not saved in the fingerprint entry process restored after the smart terminal is unlocked.

[0091] Furthermore, in another embodiment, after the step of detecting whether the fingerprint entry process saves the channel identifier, the fingerprint entry method of the present invention further includes:

[0092] Step S40: If it is detected that the fingerprint entry process has saved the fingerprint channel identifier, fingerprint continued entry is performed based on the fingerprint channel specified by the channel identifier.

[0093] If it is detected that the currently restored fingerprint entry process still stores a channel identifier indicating that the fingerprint module has been connected to the fingerprint channel when the terminal was performing fingerprint entry, the fingerprint channel to which the fingerprint module has been connected is determined based on the channel identifier, and the fingerprint input by the user continues to be entered.

[0094] Specifically, for example, when the smart terminal unlocks the screen and obtains the fingerprint entry process that was running in the foreground of the terminal when the smart terminal was locked, as indicated by the fingerprint entry interface that is restored and displayed by the smart terminal based on the onResume method, it is further detected that the fingerprint entry process currently restored by the smart terminal still stores a channel identifier for identifying that the fingerprint module of the smart terminal is currently connected to a fingerprint channel. Then, on the fingerprint entry interface currently restored and displayed on the screen of the smart terminal, a dialog box prompting the user to continue the fingerprint entry operation is output, and based on the confirmation instruction fed back by the user, the fingerprint input by the user based on the touch and press operation is recognized again, and the recognized fingerprint is stored as fingerprint sample data.

[0095] It should be noted that when the user performs a fingerprint entry operation based on the same finger as the unlocking fingerprint before the smart terminal locks the screen, when the user unlocks the smart terminal based on the finger with the unlocking fingerprint, the smart terminal does not need to switch the fingerprint channel because the fingerprints collected during the fingerprint entry process and the fingerprint recognition and unlocking process are the same. That is, at this time, the channel identifier used to identify that the fingerprint module is connected to the fingerprint channel is still saved in the fingerprint entry process of the current smart terminal.

[0096] Step S30: switching the fingerprint channel according to the fingerprint continuation instruction, and performing fingerprint continuation based on the switched fingerprint channel.

[0097] After the channel identifier is not detected on the currently restored fingerprint entry process and a fingerprint continuation instruction is generated to continue entering fingerprints based on the currently restored fingerprint entry process, the fingerprint channel of the terminal connected to the fingerprint sample database is switched to the fingerprint entry module of the fingerprint entry process based on the fingerprint continuation instruction, and fingerprint continuation is performed based on the connected fingerprint channel.

[0098] Specifically, for example, when it is detected that the fingerprint entry process currently restored by the smart terminal does not store a channel identifier for identifying that the fingerprint module of the smart terminal is currently connected to the fingerprint channel, a fingerprint continuation instruction is generated based on the fingerprint entry process currently restored by the smart terminal to continue the fingerprint entry operation. After the fingerprint continuation instruction is sent to the driver layer of the smart terminal, the driver layer switches the fingerprint channel of the fingerprint unlocking module currently connected to the fingerprint unlocking process of the smart terminal to the fingerprint entry module of the fingerprint entry process that has been restored by the smart terminal based on the fingerprint continuation instruction. After completing the fingerprint channel switching, a dialog box prompting the user to continue the fingerprint entry operation is output on the fingerprint entry interface currently restored and displayed on the screen of the smart terminal. Based on the confirmation instruction fed back by the user, the fingerprint input by the user based on the touch and press operation is recognized again, and the recognized fingerprint is stored as fingerprint sample data.

[0099] For further information, please refer to Figure 4 , Figure 4 FIG. 5 is a detailed flow chart of step S30 of the fingerprint entry method of the present invention. Step S30 includes:

[0100] Step S301, obtaining the channel identifier carried in the fingerprint continuation instruction, and switching the fingerprint channel of the terminal fingerprint module to the fingerprint entry process based on the channel identifier.

[0101] It should be noted that the channel identifier is saved on the fingerprint entry process that is not currently restored, and the fingerprint continuation instruction generated based on the currently restored fingerprint entry process to continue entering fingerprints carries the fingerprint module of the designated terminal and the channel identifier of the connected fingerprint channel.

[0102] Specifically, for example, detect and obtain the fingerprint entry process generated based on the current recovery, the fingerprint continuation instruction for continuing to enter the fingerprint carries the fingerprint module used to identify the terminal when performing fingerprint entry, the channel identifier of the connected fingerprint channel, and based on the channel identifier, the fingerprint channel of the terminal currently connected to the fingerprint unlocking module is switched to the fingerprint entry module of the fingerprint entry process currently restored based on the onResume method.

[0103] Step S302: acquiring the fingerprint re-recorded by the user through the switched fingerprint channel, and storing the re-recorded fingerprint.

[0104] After the switching connection of the fingerprint channel is completed, in the currently restored fingerprint entry process, the fingerprint channel to which the fingerprint module has been connected is determined through the channel identifier, the fingerprint input by the user continues to be entered, and the entered fingerprint is stored in the fingerprint sample data of the terminal.

[0105] Specifically, for example, after the driver layer switches the fingerprint channel of the terminal currently connected to the fingerprint unlocking module to the fingerprint entry module of the fingerprint entry process currently restored based on the onResume method, a dialog box prompting the user to continue the fingerprint entry operation is output on the fingerprint entry interface currently restored on the screen of the smart terminal, and based on the confirmation instruction fed back by the user, the fingerprint input by the user based on the touch and press operation is recognized again, and the recognized fingerprint is stored as fingerprint sample data in the fingerprint sample database of the smart terminal.

[0106] In this embodiment, when the terminal releases the lock screen state based on identifying the unlocking fingerprint, the terminal immediately restores the fingerprint entry process that was running in the foreground when the screen was locked. After the fingerprint entry process is restored, it is detected whether the fingerprint entry process currently restored by the terminal still stores a channel identifier that indicates that the fingerprint module of the terminal has been connected to the fingerprint channel when the terminal performed fingerprint entry. If the channel identifier is not detected in the currently restored fingerprint entry process, a fingerprint continuation instruction is generated to continue entering fingerprints based on the currently restored fingerprint entry process. Based on the fingerprint continuation instruction, the fingerprint channel of the terminal connected to the fingerprint sample database is switched to the fingerprint entry module of the fingerprint entry process, and fingerprint continuation is performed based on the connected fingerprint channel.

[0107] The invention realizes that after the terminal is unlocked based on the unlocking fingerprint, the fingerprint channel of the terminal fingerprint module has been switched to the fingerprint unlocking process, and the fingerprint recording process restored after the terminal is unlocked is not connected to the fingerprint channel required for fingerprint recording, a fingerprint continuation instruction containing a channel identifier specifying the fingerprint channel required for the current fingerprint recording process is generated, after the instruction is detected, based on the channel identifier carried in the instruction, the fingerprint channel of the terminal fingerprint module connected to the fingerprint unlocking process is switched back to the fingerprint recording process currently restored by the terminal, and the fingerprint recorded by the user is re-recorded and stored based on the fingerprint channel, so that, in the process of recording fingerprints, after the terminal with multiple fingerprint modules switches the fingerprint channel based on different unlocking fingerprints, after the fingerprint recording process is restored, the fingerprint channel is switched back to the restored fingerprint recording process, so that the user can continue to record the fingerprint on the original fingerprint recording process restored after the terminal is unlocked after the fingerprint recording process is interrupted by the terminal lock screen, thereby avoiding the problem that the terminal is locked during the fingerprint recording process, and the fingerprint recording process cannot be continued after being unlocked by the unlocking fingerprint, thereby improving the recording efficiency of the fingerprints of the terminals with multiple fingerprint modules.

[0108] Further, based on the first embodiment of the fingerprint entry method of the present invention, a second embodiment of the fingerprint entry method of the present invention is proposed. In this embodiment, after the step of detecting that the fingerprint entry process does not save the channel identifier, the fingerprint entry method of the present invention further includes:

[0109] Step B: Jump the fingerprint entry interface currently restored and displayed by the terminal to the fingerprint entry selection interface, and prompt the user to re-enter the fingerprint.

[0110] If the currently restored fingerprint entry process is not detected, and the channel identifier that indicates that the fingerprint module of the terminal was connected to the fingerprint channel when the fingerprint entry was performed is still saved, the fingerprint entry interface that has been restored by the terminal will be jumped on the terminal screen to display the previous fingerprint entry selection interface of the current fingerprint entry process, so that the user can re-start the fingerprint entry process based on the current selection interface to perform the fingerprint entry operation.

[0111] Specifically, for example, in Figure 7 In the schematic diagram of the smart terminal interface shown in the figure, when the smart terminal unlocks the screen and obtains the fingerprint entry interface that is restored and displayed by the smart terminal based on the onResume method, the fingerprint entry process that is running in the foreground of the terminal when the screen is locked is further detected. When the fingerprint entry process currently restored by the smart terminal does not store a channel identifier for identifying that the fingerprint module of the smart terminal is currently connected to a fingerprint channel, the currently restored fingerprint entry process is displayed on the terminal screen. Figure 7 The fingerprint entry interface shown in B will jump to the display as shown in Figure 7A is a selection interface for the previous fingerprint entry in the fingerprint entry process, so that the user can restart the fingerprint entry process based on the selection interface to perform the fingerprint entry operation.

[0112] Furthermore, the fingerprint entry method of the present invention further comprises:

[0113] Step C: when a lock screen message broadcast by the terminal system is detected, the fingerprint entry interface currently displayed on the terminal is redirected to a fingerprint entry selection interface, and the user is prompted to re-enter the fingerprint after the terminal is unlocked.

[0114] The terminal system broadcasts a lock screen message to all currently running processes of the terminal before the terminal is locked. When the lock screen message is detected, the fingerprint entry interface currently displayed on the terminal screen will jump to display the previous fingerprint entry selection interface of the current fingerprint entry process, so that the user can re-select the fingerprint module on the current selection interface to enter the fingerprint after the terminal is unlocked.

[0115] It should be noted that when the smart terminal has not received any user input for a long time and before entering the lock screen state, the terminal system will broadcast a lock screen message to each running process that is still running in the terminal, so that each running process can save parameters such as the current running progress.

[0116] Specifically, for example, when the intelligent terminal is about to lock the screen because it has not received any user operation for a long time, the intelligent terminal system broadcasts a lock screen message. After detecting the lock screen message, the control terminal ends the fingerprint entry process currently in operation and jumps to the current display of the terminal. Figure 7 The fingerprint entry interface shown in B is as follows Figure 7 The previous fingerprint entry selection interface in the fingerprint entry process shown in A allows the user to restart the fingerprint entry process to perform fingerprint collection and entry operations on the fingerprint entry selection interface restored based on the onResume method after the smart terminal is unlocked.

[0117] In this embodiment, if it is not detected that the currently restored fingerprint entry process still stores the channel identifier that indicates that the fingerprint module of the terminal has been connected to the fingerprint channel when the terminal performs fingerprint entry, the fingerprint entry interface that has been currently restored by the terminal will be jumped on the terminal screen to display the previous fingerprint entry selection interface of the current fingerprint entry process, so that the user can re-start the fingerprint entry process based on the current selection interface to perform the fingerprint entry operation; the lock screen message broadcast by the terminal system to all the currently running processes of the terminal before the terminal is locked is detected. When the lock screen message is detected, the fingerprint entry interface currently displayed on the terminal screen will be jumped to display the previous fingerprint entry selection interface of the current fingerprint entry process, so that the user can re-select the fingerprint module on the current selection interface to enter the fingerprint after the terminal is unlocked.

[0118] The invention realizes that the fingerprint entry interface in the terminal fingerprint entry process directly jumps to the fingerprint entry selection interface in the current fingerprint entry process, so that the user can directly trigger the fingerprint entry instruction on the selection interface after the terminal is unlocked to restart the fingerprint entry process to collect and enter the fingerprint, thereby avoiding the problem that the terminal is locked during the fingerprint entry process and cannot continue the fingerprint entry before the lock screen after the fingerprint is unlocked, thereby further improving the fingerprint entry efficiency.
