The first electronic device 100 may switch and display the state of the control 253 between an open state and a closed state in response to a user operation (for example, a touch operation acting on the control 253). The control 253 is in an open state, which means that the text received by the input box 252 is displayed in a hidden form. The control 253 is in the closed state, which means that the text received by the input box 252 is displayed in a visible form.

In response to a user operation on the control 254, such as a touch operation, the first electronic device 100 may send the text received in the input box 252 to the second electronic device 200 via a Bluetooth connection. The second electronic device 200 detects whether the received text is the same as the pre-stored unlock password. If they are the same, the second electronic device 200 sends a notification to the first electronic device 100, and the notification is used to notify that the unlocking password has been verified. After receiving the notification, the first electronic device 100 stores the relationship between the dedicated fingerprint information and unlocking the function of the second electronic device 200. Through this relationship, the first electronic device 100 can send an unlocking instruction to the second electronic device 200 when detecting that the fingerprint information input by the user matches the dedicated fingerprint information.

In the embodiment of the present application, the user interface 25 may also be displayed before the special fingerprint information is collected, that is, before the user interface 23 is displayed. For example, in response to detecting a touch operation on the option 226 on the user interface 22, the first electronic device 100 displays the user interface 25. After the unlocking password of the second electronic device 200 is verified, the first electronic device 100 may display the user interface 23 and the user interface 24 in response to the touch operation on the control 254.

It is not limited to displaying the user interface 25 on the first electronic device 100 to verify the unlocking password of the second electronic device 200. The unlocking password of the second electronic device 200 may also be verified in the second electronic device 200, and then the second electronic device 200 may send the verification result to the first electronic device 100 via the Bluetooth connection.

After the dedicated unlocking fingerprint information is set through the process shown in (A) to (D) in FIG. 9, the setting entry 226 on the user interface 22 shown in FIG. 10 prompts "special fingerprint" 226a. The fingerprint list 228 also includes a “special fingerprint” identification 228a, which may prompt “only for unlocking the PC”.

The input box 162 is used to input text and can receive an unlock password. The input box 252 may prompt "password".

In response to a user operation on the control 163, such as a mouse click operation on the control 163, the second electronic device 200 detects whether the text received in the input box 162 is the same as the pre-stored unlock password. If the same, the second electronic device 200 unlocks and displays the unlocked user interface, such as a desktop. The application icon on the desktop can respond to the double-click operation of the mouse, so that the second electronic device 200 starts the corresponding application and displays the user interface corresponding to the application.

The control 164 is used to switch to another user name.

After going through the examples described in FIGS. 4 to 9, the first electronic device 100 may send an unlocking instruction to the second electronic device 200 in response to the fingerprint corresponding to the dedicated fingerprint information input by the user. The second electronic device 200 can detect whether the first electronic device 100 from which the unlocking instruction comes is a trusted device according to the unlocking instruction, and detect whether the signal strength of the Bluetooth connection is greater than a set threshold. If the first electronic device 100 is a trusted device and the signal strength of the Bluetooth connection is greater than the set threshold, the second electronic device 200 performs unlocking.

Specifically, please refer to FIG. 12, which is a schematic diagram of some user interfaces provided by embodiments of the present application. As shown in (A) of FIG. 12, the second electronic device 200 is in a locked state, and the user interface 16 is displayed. The first electronic device 100 may collect fingerprint information through a fingerprint recognizer. When the collected fingerprint information is dedicated fingerprint information, the first electronic device 100 may notify the second electronic device 200 to unlock. When the first electronic device 100 is a trusted device and the signal strength of the Bluetooth connection is greater than the set threshold, the second electronic device 200 performs unlocking. As shown in (B) of FIG. 12, the second electronic device 200 displays the user interface 17, that is, displays the desktop.

As shown in (B) of FIG. 12, the user interface 17 may include an application icon list 171, a mouse prompt 172, and a toolbar 173. among them:

The toolbar 173 may include multiple tool options, such as a “start” option, a volume option, and so on. The toolbar 173 may also include application icons, for example, a WeChat application icon, a word application icon, and an excel application icon.

As shown in (A) and (B) in Figure 12, when the first electronic device 100 is locked, it can collect the dedicated fingerprint information of the second electronic device 200 and perform fingerprint information verification. When the dedicated fingerprint information corresponding to the device 200 matches, the second electronic device 200 is notified to unlock. After the second electronic device 200 receives the unlocking instruction, when the signal strength of the Bluetooth connection is greater than or equal to the first threshold and the trusted information includes the device identification of the first electronic device 100, the unlocking is performed.

Among them, the user's authority to operate the first electronic device 100 in the locked screen state is limited. After verifying the user's identity (for example, verifying face information, fingerprint information, etc.), the first electronic device can open and close applications installed on the first electronic device 100 in response to user operations.

When the second electronic device 200 is in the locked state, the user's authority to operate the second electronic device 200 is limited. After verifying the user's identity (for example, verifying the password, fingerprint information, etc.), the second electronic device 200 can open and close the application installed on the second electronic device in response to the user's operation.

In the examples shown in (A) and (B) in FIG. 12, the first electronic device 100 does not need to be in the unlocked state to verify the dedicated fingerprint information for unlocking the second electronic device 200. In this way, the operation flow of unlocking the second electronic device 200 is reduced, and the convenience of unlocking is improved.

The user interface displayed after the second electronic device 200 is unlocked is not limited to the desktop, and may be the user interface displayed before the second electronic device 200 is locked.

It is not limited to the locked screen state. When the first electronic device 100 is in the unlocked state, fingerprint information can also be collected and verified through the fingerprint recognizer, and the second electronic device 200 is notified to unlock when it is verified that the dedicated fingerprint information corresponding to the second electronic device 200 matches. The embodiment of the present application does not limit the state of the first electronic device 100.

Not limited to the locked state, the second electronic device 200 may also be unlocked after receiving the notification when the screen is off, to display the user interface 17. Wherein, in the off-screen state, the display screen of the second electronic device 200 is in the off state.

Let's take a specific scenario as an example. The first electronic device 100 is a mobile phone, and the second electronic device 200 is a PC. The PC is in a locked state, that is, the PC can display the user interface 13. After the setup process described in Figures 4-10, Xiao Ming holds the mobile phone close to the PC, and inputs special fingerprint information (for example, the fingerprint information corresponding to the fingerprint of the left index finger) on the mobile phone. When the mobile phone is close to the PC, the signal strength of the Bluetooth connection with the PC is greater than the first threshold. After the mobile phone detects that the fingerprint is the dedicated fingerprint information of the PC, it sends an unlocking instruction to the PC. After the PC detects the unlocking instruction, it can unlock the PC when it detects that the device name "Mate20PRO" of the mobile phone is included in the trusted device list, and the signal strength of the Bluetooth connection is greater than or equal to the first threshold. That is, the PC can display the user interface 17. In this way, fingerprint information can be collected and authenticated on the mobile phone, and the PC can be unlocked after the authentication succeeds, thereby improving the security of unlocking the PC.

In another scenario, after the PC is unlocked, Xiao Ming needs to carry the phone away from the PC to make and receive calls. When Xiao Ming holds the mobile phone away from the PC, the signal strength of the Bluetooth connection between the mobile phone and the PC is less than the second threshold. When the PC detects that the signal strength of the Bluetooth connection is less than or equal to the second threshold, it can lock the PC. In this way, when Xiao Ming is not near the PC, the PC can be automatically locked, thereby reducing information leakage on the PC and improving the security of the information on the PC.

The following describes the device unlocking method provided by the embodiment of the present application.

The device unlocking method provided by the embodiment of the present application may include the following processes: (1) the process of storing dedicated fingerprint information in the first electronic device 100 and storing the list of trusted devices in the second electronic device 200. (2) The process of using the fingerprint reader on the first electronic device 100 to unlock the second electronic device 200. Please refer to FIG. 13, which is a schematic flowchart of a method for unlocking a device according to an embodiment of the present application. As shown in FIG. 13, the process of storing dedicated fingerprint information by the first electronic device 100 and storing the list of trusted devices by the second electronic device 200 may include steps S101 to S103. The process of using the fingerprint reader on the first electronic device 100 to unlock the second electronic device 200 may include steps S104 to S112. The following are introduced separately.

S101. The first electronic device 100 and the second electronic device 200 establish a Bluetooth connection.

For the process of establishing a Bluetooth connection between the first electronic device 100 and the second electronic device 200, reference may be made to the detailed description of the user interface described in FIGS. 4-6.

After the Bluetooth connection is established, the second electronic device 200 can store the connection record. After the Bluetooth connection is disconnected, when the first electronic device 100 approaches the second electronic device 200 again, the second electronic device 200 reconnects with the first electronic device according to the connection record. The device 100 establishes a Bluetooth connection.

S102. The first electronic device 100 stores the dedicated fingerprint information of the second electronic device 200.

Wherein, the dedicated fingerprint information of the second electronic device 200 is used to verify the fingerprint information input by the user on the first electronic device 100, and if the verification is passed, an unlocking instruction is sent to the second electronic device 200. For the process of storing the dedicated fingerprint information of the second electronic device 200 by the first electronic device 100, reference may be made to the detailed description of the user interface described in FIGS. 9-11.

S103. The second electronic device 200 stores a list of trusted devices, where the list of trusted devices includes the identity of the first electronic device 100.

For the process of storing the list of trusted devices by the second electronic device 200, reference may be made to the detailed description of the user interface described in FIGS. 7-8.

S104. The first electronic device 100 detects fingerprint information input by the user.

In the embodiment of the present application, the first electronic device 100 can detect the fingerprint information input by the user through a fingerprint recognizer. The fingerprint reader is, for example, a capacitive type, a radio frequency type, or an optical type. Capacitive fingerprint readers collect fingerprint information through changes in capacitance. The radio frequency fingerprint recognizer collects fingerprint information through radio frequency signals. The optical fingerprint recognizer collects fingerprint information through the principle of light refraction and reflection, and the optical fingerprint recognizer is, for example, an under-screen fingerprint module.

S105. The first electronic device 100 verifies the fingerprint information.

After the fingerprint information is collected by the fingerprint recognizer, the first electronic device 100 respectively compares the collected fingerprint information with the stored fingerprint information. The stored fingerprint information can be one or more. For example, the first electronic device 100 stores fingerprint information identified by “fingerprint 1”, fingerprint information identified by “fingerprint 2”, and fingerprint information identified by “special fingerprint”. Refer to the example described in FIG. 10. The first electronic device 100 compares the collected fingerprint information with the three fingerprint information respectively. When the collected fingerprint information matches the fingerprint information identified by the "special fingerprint", step S106 is executed.

Here, fingerprint information matching means that the similarity between two fingerprint information is greater than a set threshold.

S106: When it is detected that the fingerprint information matches the dedicated fingerprint information corresponding to the second electronic device 200, the first electronic device 100 sends an unlocking instruction to the second electronic device 200.

S107. After receiving the unlocking instruction, the second electronic device 200 detects whether the first electronic device 200 that sends the unlocking instruction is a trusted device.

Here, the second electronic device 200 may detect whether the device name or MAC address of the first electronic device 100 is included in the trusted device list to determine whether the first electronic device 200 is a trusted device. If the device name or MAC address of the first electronic device 100 is included in the trusted device list, the first electronic device 200 is a trusted device. If the device name or MAC address of the first electronic device 100 is not included in the trusted device list, the first electronic device 200 is not a trusted device.

In some embodiments, the second electronic device 200 may also obtain the device name or MAC address of the first electronic device 100 according to the Bluetooth connection with the first electronic device 100. In other embodiments, the unlocking instruction may be sent through the Bluetooth connection between the first electronic device 100 and the second electronic device 200. The unlocking instruction may carry the device name or MAC address of the first electronic device 100.

S108. The second electronic device 200 detects whether the signal strength of the Bluetooth connection with the first electronic device 100 is greater than a first threshold.

In the embodiment of the present application, the second electronic device 200 may detect the received signal strength indication (RSSI) to determine the signal strength of the Bluetooth connection. If the RSSI is greater than the first threshold, it indicates that the signal strength of the received Bluetooth connection is greater than the first threshold. Among them, when the Bluetooth unlocking service of the application layer is running, the Bluetooth unlocking service (Bluetooth Serivce) can perform RSSI detection.

In another possible embodiment, the second electronic device 200 may periodically monitor the RSSI.

Wherein, step S107 and step S108 do not limit the execution order, and the second electronic device 200 may also first determine whether the signal strength of the Bluetooth connection is greater than the first threshold. When the signal strength of the Bluetooth connection is greater than the first threshold, it is detected whether the first electronic device 100 is a trusted device.

S109. When it is detected that the first electronic device 100 is a trusted device and the signal strength is greater than the first threshold, the second electronic device 200 detects whether it is in a locked state.

S110. When the second electronic device 200 is in the locked state, the second electronic device 200 performs unlocking.

Refer to the detailed description of the user interface described in FIG. 9 for the process of the second electronic device 200 performing unlocking.

S111. When it is detected that the signal strength is less than the second threshold, the second electronic device 200 detects whether it is in an unlocked state.

Wherein, the second threshold may be smaller than the first threshold.

S112. When the second electronic device 200 is in an unlocked state, the second electronic device 200 performs locking.

After the second electronic device 200 performs the lock, the user interface 13 is displayed.

In the embodiment of the present application, when the option 1581 in the example described in FIG. 8 is in the selected state, it indicates that the second electronic device has enabled the dedicated fingerprint unlocking function, and the second electronic device 200 performs the unlocking process of steps S107 to S110. When the first electronic device 100 detects that the collected fingerprint information matches the dedicated fingerprint information, it will send an unlocking instruction to the second electronic device 100. After receiving the unlocking instruction, the second electronic device 200 detects that the first electronic device 100 is a trusted device and the signal strength is greater than the first threshold before unlocking the locked state. In this way, fingerprint information can be collected and authenticated through the fingerprint recognizer on the first electronic device 100, thereby improving the security of unlocking. In addition, the second electronic device 200 also performs trusted device detection and signal strength detection to further improve the security of unlocking.

In the embodiment of the present application, after the second electronic device 200 is unlocked, it directly displays the user interface 17, such as a desktop, and there is no need to input the CTRL+ALT+DEL shortcut key to make the second electronic device 200 display the desktop. In this way, user operations are saved and the convenience of unlocking the device is improved.

In a possible implementation manner, the first electronic device 100 may also verify that it matches the dedicated fingerprint information before establishing a Bluetooth connection with the second electronic device 200. Specifically, the first electronic device 100 may detect that the collected fingerprint information matches the dedicated fingerprint information. If the Bluetooth connection with the second electronic device 200 has not been established, the first electronic device 100 can detect whether the Bluetooth connection with the second electronic device 200 is established within a set time (for example, 2 minutes) after the fingerprint is matched. If a Bluetooth connection is established with the second electronic device 200 within the set time, the first electronic device 100 can send an unlocking instruction to the second electronic device 200 through the Bluetooth connection. If the Bluetooth connection with the second electronic device 200 is not established after the set time, the first electronic device 100 does not perform any operation for the matching dedicated fingerprint information detected this time.

The following is a scenario to illustrate that a Bluetooth pairing has been performed between the user's mobile phone and the computer, but the Bluetooth connection has not been established. When the user holds the mobile phone close to the computer, the mobile phone has detected that the collected fingerprint information matches the dedicated fingerprint information when the Bluetooth connection has not been established. When the user continues to hold the mobile phone close to the computer, the Bluetooth connection between the mobile phone and the computer is successful 5 seconds after the fingerprint matching is detected. Then the mobile phone sends an unlocking instruction to the computer through the Bluetooth connection. The computer detects the Bluetooth connection signal strength according to the unlocking instruction and detects whether the mobile phone is a trusted device. If the Bluetooth connection signal strength is greater than the first threshold, and the mobile phone is a trusted device, the computer will unlock and display the desktop.

In the device unlocking solution described above, when the first electronic device 100 does not establish a Bluetooth connection with the second electronic device 200, the first electronic device 100 can still match the dedicated fingerprint information, and then send the second electronic device to the second electronic device after the Bluetooth connection is established. 200 sends an unlock command. In this way, the fingerprint verification process can be performed in advance before the Bluetooth connection is established, which can improve the efficiency of Bluetooth unlocking. In addition, the situation that the user cannot unlock the second electronic device after inputting a fingerprint before the connection is established is reduced, and the convenience of Bluetooth unlocking is improved.

When the option 1581 in the example described in FIG. 8 is in the unselected state, the second electronic device 200 may perform unlocking when detecting that the first electronic device 100 is a trusted device and the signal strength is greater than the first threshold. Specifically, please refer to FIG. 14, which is a schematic flowchart of a method for unlocking a device according to an embodiment of the present application. As shown in FIG. 14, the process of using the fingerprint reader on the first electronic device 100 to unlock the second electronic device 200 may include steps S201 to S212.

S201. The second electronic device 200 is turned on, and the Bluetooth chip is turned on by default.

After the Bluetooth chip is turned on, the Bluetooth unlocking service can be run.

S202: The second electronic device 200 detects whether the trusted device list is empty through the Bluetooth unlock service.

S203. When the trusted device list is not empty, the second electronic device 200 monitors whether there is a Bluetooth connected device.

S204: When the trusted device list is empty, the second electronic device 200 turns off the Bluetooth unlocking service.

Wherein, after the second electronic device 200 turns off the Bluetooth unlocking service, it no longer monitors whether it is a trusted device or the signal strength.

S205: When it is monitored that the first electronic device 100 and the second electronic device 200 establish a Bluetooth connection, the second electronic device 200 detects whether the first electronic device 100 is a trusted device.

S206: When it is detected that the first electronic device 100 is a trusted device, the second electronic device 200 monitors whether the signal strength of the Bluetooth connection with the first electronic device 100 is greater than the first threshold.

S207: When it is monitored that the signal strength of the Bluetooth connection with the first electronic device 100 is greater than the first threshold, the second electronic device 200 detects whether it is in a locked state.

S208: When the second electronic device 200 is in the locked state, the second electronic device 200 performs unlocking.

S209: When it is monitored that the signal strength is less than the second threshold, the second electronic device 200 detects whether it is in an unlocked state.

S210: When the second electronic device 200 is in an unlocked state, the second electronic device 200 performs locking.

When the option 1581 is in the unselected state, it indicates that the second electronic device 200 has not enabled the dedicated fingerprint unlocking function. The second electronic device 200 can unlock the second electronic device 200 when the first electronic device 100 is close to the second electronic device 200 without using fingerprint information or other information for authentication, thereby improving the convenience of unlocking. This is achieved in response to the user's setting through option 1581, which improves the security of unlocking.
