Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terminal to which the present application relates may be: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a digital camera, a Personal Digital Assistant (PDA), a navigation Device, a Mobile Internet Device (MID) or a Wearable Device (Wearable Device), such as a bracelet, a watch, etc.

Fig. 1 is a schematic view of a scenario applied in the embodiment of the present application. In the illustration of fig. 1, the terminal has failed to unlock. The method and the device can solve the problem that a user cannot unlock the terminal screen in the scene of forgetting the unlocking password of the terminal screen. Specific implementations may include the following: firstly, when the terminal sets or modifies the unlocking password, an unlocking terminal (also called a trusted unlocking device) is set, and the unlocking terminal is used for unlocking the terminal so that the terminal enters an operation interface. And secondly, generating a unique scanning code when the terminal sets or modifies the unlocking password, wherein the scanning code comprises the unlocking password and the unique identification code of the terminal. It should be understood that the unique identifier may be an International Mobile Equipment Identity (IMEI) of the terminal, a Serial Number (SN), or other identifiers to uniquely identify different terminals. When a user forgets an unlocking password of the terminal, the user can utilize the unlocking terminal or a scanning code to force password clearing or password resetting operation, or obtain the unlocking password from the unlocking terminal to unlock the current terminal, or scan a one-dimensional bar code, a two-dimensional code, a three-dimensional code, a four-dimensional code and the like to unlock the current terminal. The technical solution of the present application will be further described by way of examples as follows.

Fig. 2 is a schematic diagram of an embodiment of a method for unlocking a screen in an embodiment of the present application. This scheme is the example that realizes terminal screen unblock through the unblock terminal, and it specifically includes:

201. the first terminal sets an unlocking password.

The screen locking means that the screen of the terminal is in a locked state. In the embodiment of the application, the first terminal supports that the locking state of the current screen is released by unlocking the password in the screen locking state. The unlocking password type applied by the first terminal can comprise password unlocking of a digital password, a sliding track, a fingerprint and the like. The first terminal may set or modify the unlocking password. Fig. 3A is a schematic diagram of the unlocking password set by the first terminal being a digital password. Fig. 3B is a schematic diagram of the unlocking password set by the first terminal being a sliding track. Fig. 3C is a schematic diagram of the unlocking password set by the first terminal being a fingerprint.

The terminal screen locking mainly has two types: one is to lock the screen with beautifying as the main function; one is a lock screen which mainly plays a role in safety, and when the lock screen is unlocked, a password needs to be input or a correct squared figure needs to be drawn. The technical scheme is suitable for the lock screen which is unlocked by inputting the password or drawing the correct Sudoku pattern regardless of the lock screen which mainly plays a role of safety or the lock screen which mainly plays a role of beauty. The screen locking state is the locking state before unlocking, such as password input or correct drawing of Sudoku patterns and the like. The lock screen is related to the black screen and the information screen, and the lock screen and the information screen are different. In general, the black screen state is a state in which the screen is not lit or is not powered on. The screen turning-on state is a screen turning-off state, and if the terminal is not locked (namely the screen of the terminal is not locked), a user can directly enter a desktop by pressing a power key to turn on the screen; if the terminal is locked (namely the screen of the terminal is locked), the user presses a power key to light the screen, and the terminal can display a screen locking interface in a screen lighting state. When the mobile phone is defaulted to be on, the mobile phone does not operate for a first preset time (such as 15s), the mobile phone automatically turns off the screen, and after the mobile phone turns off the screen, the mobile phone does not operate for a second preset time (such as 5s), and the mobile phone is locked; or, when the mobile phone is on the screen, the mobile phone can be locked immediately and enters a screen-rest state by pressing the power key.

202. The first terminal sets the second terminal as a trust unlocking device and sends authentication information to the second terminal.

In the embodiment of the application, a user sets a trusted unlocking device for a first terminal, wherein the trusted unlocking device can be set by a second terminal while an unlocking password is initially set by the first terminal; or after the first terminal has set the unlocking password for a period of time, the user sets the second terminal as the trusted unlocking device in consideration of actual requirements; or when the user modifies the unlocking password of the first terminal, the trusted unlocking device is set for the first terminal. The scenario in which the user sets the trusted unlocking device for the first terminal is not limited.

For example, the unlocking password set by the first terminal is taken as a sliding track for explanation. After the unlocking password is set, the user can click to finish or perform the next operation, a prompt box can be popped up on the first terminal to prompt whether to set the trusted unlocking device so as to prevent forgetting the password and other similar information. If the user selects "yes", the first terminal may display an interface prompting the user to fill in authentication information in response to the user's operation. The authentication information may include, for example: the unique identification code of the first terminal and the unique identification code of the second terminal; or the unique identification code of the first terminal, the unique identification code of the second terminal and the appointment password; or the unique identification code of the first terminal, the unique identification code of the second terminal and the unlocking password of the first terminal; or other information such as the unique identification code of the first terminal, the unique identification code of the second terminal, the appointed password, the unlocking password of the first terminal and the like. The unique identification code of the first terminal is used for uniquely identifying the first terminal, and the unique identification code of the second terminal is used for uniquely identifying the second terminal.

Setting the agreed password is a way for security verification. The unlocking password of the first terminal can be used for sending the unlocking password to the first terminal by the second terminal to unlock the first terminal when the unlocking of the first terminal fails. For the unique identification code of the first terminal, the first terminal can automatically identify and acquire, and the unique identification code of the second terminal can be manually input by a user.

And after the user fills the authentication information, the next operation is carried out, and the mode of sending the authentication information to the second terminal is selected. For example, fig. 3D is a schematic diagram illustrating the first terminal setting the second terminal as a trusted unlocking device. As shown in fig. 3D, the first terminal may send the authentication information to the second terminal in a manner of hiShare, bluetooth, Wireless Fidelity (WIFI), a software account of a third-party application (such as a micro signal, a QQ number, etc.), a short message, and the like. Further, the first terminal may prompt that the authentication information is successfully sent, or may not prompt, and is not particularly limited. It should be noted that the interaction between the terminals may include: one is interaction in a short-distance wireless communication mode, such as bluetooth, WIFI direct connection, and the like; one is to interact through a third-party server, for example, WeChat, QQ and short message are all transferred through the server.

Optionally, in a specific implementation manner, as shown in fig. 3E, before the authentication information is filled in, the manner of selecting to send the authentication information may also be that, fig. 3E is a schematic diagram of setting the second terminal as the trusted unlocking device for the first terminal.

It should be noted that, the first terminal sends the authentication information to the second terminal, where the authentication information may be sent by the user, and a long-press operation is executed after the user fills the authentication information, the first terminal responds to the long-press operation of the user, and displays an "address book, a WeChat friend, a QQ friend, and the like", and the user selects again, and if the address book is selected, the first terminal may display a contact in the address book, select a contact A, and send the authentication information to the contact A in a short message manner; and if the WeChat friend is selected, the first terminal displays the WeChat friend, selects the friend B and sends authentication information to the friend B. It should be understood that the manner in which the first terminal determines the authentication information, and the manner in which the authentication information is transmitted to the second terminal are not particularly limited.

203. The second terminal establishes a trust mechanism with the first terminal.

In the embodiment of the application, the second terminal receives authentication information sent by the first terminal, and the authentication information includes a unique identification code of the first terminal and a unique identification code of the second terminal. The unique identification code of the first terminal is used for indicating that the second terminal is determined as the trust unlocking equipment of the first terminal; the unique identification code of the second terminal is used for matching with the identification code of the second terminal, if the matching is successful, the second terminal can default to trust unlocking equipment of the first terminal, establish a trust mechanism with the first terminal, and store the unique identification code of the first terminal, namely, the unique identification code of the first terminal has the authority to unlock the first terminal. Fig. 3F is a schematic diagram of the second terminal establishing a trust mechanism with the first terminal. As shown in fig. 3F, after the second terminal receives the authentication information, if the authentication information is successfully matched, the second terminal may display a prompt message indicating that the matching is successful. If the matching is not successful, the establishment of the trust mechanism fails, and the second terminal has no permission to unlock the first terminal.

Optionally, fig. 3G is a schematic diagram of establishing a trust mechanism between the second terminal and the first terminal. In fig. 3G, after the second terminal receives the authentication information and passes the verification, the user may confirm the verification information again, that is, may prompt "do the second terminal agree with the trusted unlocking device of the first terminal? "and the like. And if the user clicks 'consent', the second terminal responds to the operation of the user, establishes a trust mechanism with the first terminal, stores the unique identification code of the first terminal, becomes trust unlocking equipment of the first terminal and can unlock the first terminal. If the user does not agree with the first terminal, the second terminal responds to the operation of the user, the establishment of the trust mechanism with the first terminal fails, and the second terminal cannot unlock the first terminal.

Alternatively, fig. 3H is a schematic diagram of the second terminal establishing the trust mechanism with the first terminal. In fig. 3H, the authentication information further includes an agreed password, and the agreed password is used to ensure the security of the authentication information. Therefore, the second terminal not only needs to be matched with the unique identification code of the second terminal, but also needs to verify the appointed password, and when both the unique identification code and the appointed password indicate success, the second terminal can default to be the trust unlocking device of the first terminal and establish a trust mechanism with the first terminal. And if the verification of the appointed password by the second terminal fails or the unique identification code of the second terminal fails to be matched, establishing the trust mechanism fails.

Fig. 3I is a schematic diagram of a trust mechanism established between a second terminal and a first terminal. In fig. 3I, the second terminal needs to not only match the unique identifier of the second terminal, but also verify the agreed upon password. After the second terminal verifies the appointed password, the user can confirm the verification information again, and the second terminal responds to the operation of the user and establishes a trust mechanism with the first terminal.

Optionally, the authentication information may further include an unlocking password of the first terminal. When the user of the first terminal forgets the screen locking password, the second terminal can send the unlocking password of the first terminal to the first terminal after receiving the unlocking request of the first terminal, and the unlocking password is used for unlocking the first terminal.

Optionally, after the authentication information is successfully matched by the second terminal, an authentication response may also be sent to the first terminal, where the authentication response is a response of the second terminal to the authentication request, and informs the first terminal that the establishment of the trust mechanism is successful.

It should be noted that, after the first terminal and the second terminal establish the trust mechanism, the second terminal may perform remote authorization operations on the first terminal, such as clearing a password, forcibly locking, shutting down, and the like. The forced locking can be understood as that the first terminal is lost or cannot be found, the user information is worried about leakage, remote operation can be carried out through the second terminal, and the first terminal is locked. The forced locking can also be understood as that the first terminal is not set with an unlocking password, but the user loses the first terminal, and the first terminal can be locked by setting the unlocking password for the first terminal through the second terminal. It is understood that the authentication information received by the second terminal may or may not be displayed on the display screen.

204. The first terminal responds to the operation of the user and sends an unlocking request to the second terminal.

In the embodiment of the application, the first terminal responds to the operation of a user and sends an unlocking request to the second terminal, wherein the unlocking request comprises the unique identification code of the first terminal and the unique identification code of the second terminal. The unique identification code of the first terminal is used for performing the verification action on the second terminal, and the unique identification code of the second terminal is used for finding the second terminal sending the unlocking request, namely the object sending the unlocking request.

The first terminal sending the unlocking request to the second terminal may include, but is not limited to, the following implementation manners:

(1) and if the unlocking failure times are larger than or equal to a preset threshold value in the screen locking state of the first terminal, the first terminal sends an unlocking request to the second terminal. Fig. 4A is a schematic diagram of a first terminal sending an unlocking request to a second terminal. It should be understood that, in the illustration of fig. 4A, the number of times of unlocking the first terminal within a preset time period is used up, prompting "whether to unlock by trusting the unlocking device? Or whether the password is cleared by the trusted device. The user can select 'yes' or 'no' according to the requirement, and if the user selects 'yes', the first terminal responds to the operation of the user and sends an unlocking request to the second terminal. Optionally, in a specific implementation manner, if the unlocking times within the preset time duration are used up, the first terminal may be automatically triggered to send the unlocking request to the second terminal, and the user is not required to select whether to unlock the device by trust.

(2) And if the unlocking fails in the screen locking state of the first terminal, responding to the unlocking operation input by the user, and sending an unlocking request to the second terminal by the first terminal. Fig. 4B is a schematic diagram of the first terminal sending an unlocking request to the second terminal. It should be understood that in the illustration of fig. 4B, the user may choose to trust the unlocking device to unlock the device if the unlocking password input by the user for the first time fails to unlock the device, or if the unlocking password input by the user for the second time fails to unlock the device, the first terminal sends an unlocking request to the second terminal in response to the operation of the user. For example, if the unlocking password input by the user fails to unlock, the first terminal may display a prompt message, such as "2 unlocking opportunities remain, and if the unlocking password is continuously mistaken for 3 times and is to be locked for 3 hours, you may choose to trust the device to unlock".

(3) And the first terminal responds to the unlocking operation input by the user in the screen locking state and sends an unlocking request to the second terminal. Fig. 4C is a schematic diagram of the first terminal sending an unlocking request to the second terminal. It should be understood that, in the illustration in fig. 4C, the user may directly select the trusted device to unlock without inputting an unlocking password in the screen-locked state, and the first terminal sends an unlocking request to the second terminal in response to the user operation.

(4) The method comprises the steps that when a first terminal is in a screen locking state, if the number of times of unlocking failure is larger than or equal to a preset threshold value, the first terminal presents first prompt information, the first prompt information is used for prompting a user whether to send an unlocking request to a second terminal, the first terminal obtains operation of the user based on the first prompt information, and the first terminal sends the unlocking request to the second terminal.

(5) The method comprises the steps that a first terminal acquires identity authentication information input by a user in a screen locking state; and if the identity authentication information input by the user is matched with the preset identity authentication information, the first terminal sends an unlocking request to the second terminal. For example, the authentication information may be the name of the parent, the favorite movie, the most impressive thing, etc.

(6) The first terminal presents second prompt information in a screen locking state, the second prompt information comprises contact ways of at least two contacts, and the second prompt information is used for prompting a user to select the contact to be sent with an unlocking request; the method comprises the steps that a first terminal obtains selection operation input by a user; if the contact person targeted by the selection operation is a preset contact person, the first terminal sends an unlocking request to a second terminal, and the second terminal is a terminal corresponding to the preset contact person; and if the contact person targeted by the selection operation is not the preset contact person, triggering an alarm prompt by the first terminal.

It should be understood that, when the first terminal sends the unlocking request to the second terminal, the unlocking request may be sent by means of hiShare, bluetooth, wireless fidelity, short message, Universal Serial Bus (USB), and the like, and is not limited herein.

205. And the second terminal verifies the unlocking request and sends unlocking information to the first terminal.

In this embodiment of the application, after the second terminal receives the unlocking request sent by the first terminal, the interface of the second terminal is presented as shown in fig. 4D, and fig. 4D is a schematic diagram of the second terminal sending the unlocking information. The unlocking information is information for unlocking the first terminal. The unlocking request may include a unique identification code of the first terminal, the unique identification code of the first terminal being used to uniquely identify the first terminal; and if the unique identification code of the first terminal is the same as the unique identification code pre-stored by the second terminal, the second terminal sends unlocking information to the first terminal, and the unlocking information is used for executing relevant operation of releasing the screen locking state of the first terminal.

The second terminal verifies the unlocking request and sends unlocking information to the first terminal, which may include the following situations:

the unlocking request comprises the unique identification code of the first terminal and the unique identification code of the second terminal. If the second terminal determines that the identification code of the first terminal is matched with the identification code of the first terminal in the verification information, the verification is successful, and if the second terminal verifies that the unique identification code of the second terminal is matched with the unique identification code of the second terminal, the verification is successful, and the first terminal sends unlocking information to the second terminal.

Or the unlocking request comprises the unique identification code of the first terminal, the unique identification code of the second terminal and the appointed password. The second terminal also needs to verify the agreed password included in the unlocking request, that is, if the unique identification code of the first terminal, the unique identification code of the second terminal and the agreed password are successfully verified, the second terminal sends unlocking information to the first terminal.

Or, if the unique identifier of the first terminal and the unique identifier of the second terminal are successfully verified, the second terminal may display a prompt message, which is similar to "is friend a requested to unlock, is it determined that friend a's terminal is unlocked? And the user can click other identifiers such as 'confirm' or 'yes', and the second terminal responds to the operation of the user and sends unlocking information to the second terminal.

Or, if the unique identifier of the first terminal and the unique identifier of the second terminal are successfully verified, and the agreed password is also successfully verified, the second terminal may display a prompt message, which is similar to "is friend a requesting to unlock and is determined to be friend a terminal unlock? And the user can click other identifiers such as 'confirm' or 'yes', and the second terminal responds to the operation of the user and sends unlocking information to the second terminal.

Or acquiring identity authentication information input by a user; and if the identity authentication information input by the user is matched with the preset identity authentication information, the second terminal sends unlocking information to the first terminal.

The unlocking information may include a first unlocking password of the first terminal, and the first unlocking password is used for unlocking the first terminal; or the unlocking information may include a first unlocking password of the first terminal, and a screen locking password setting interface is displayed after the first terminal is unlocked, wherein the screen locking password setting interface is used for a user to reset the unlocking password; or the unlocking information is used for forcibly clearing the first unlocking password of the first terminal, namely clearing the unlocking password of the first terminal and entering an operation interface; or the unlocking information is used for forcibly clearing the first unlocking password of the first terminal and then displaying a screen locking password setting interface, and the screen locking password setting interface is used for the user to reset the second unlocking password.

It should be noted that, the manner in which the second terminal sends the unlocking information to the first terminal may be: for example, the unlocking password included in the unlocking information is a digital password, and the second terminal may send the digital password to the first terminal in a short message, a notification, a WeChat message, a QQ message, or the like. The unlocking password included in the unlocking information is a sliding track, the second terminal can send a picture indication of the sliding track to the first terminal, and the picture indication can be sent to the first terminal in the modes of short messages, notifications, WeChat messages, QQ messages and the like. The user can slide the unlocking password to unlock the first terminal according to the sliding track displayed by the picture. The unlocking password included in the unlocking information is a fingerprint, the second terminal can send the fingerprint to the first terminal in a picture mode through short messages, notifications and the like, and the first terminal automatically identifies the fingerprint to unlock.

It should be understood that, when the second terminal sends the unlocking information to the first terminal, the unlocking information may also be sent in a manner of hiShare, bluetooth, wireless fidelity, short message, USB, and the like, which is not limited herein.

206. And the first terminal responds to the unlocking information and executes the relevant operation of releasing the screen locking state.

And after receiving the unlocking information sent by the second terminal, the first terminal uses the unlocking information to unlock. Specifically, the following situations can be included:

(1) fig. 4E is a schematic diagram of unlocking the first terminal. In fig. 4E, the unlocking information includes a first unlocking password of the first terminal. If the first unlocking password is a digital password, the second terminal can send the first unlocking password in a short message, a notification, a WeChat message, a QQ message and the like, and the user can manually input the first unlocking password to unlock the terminal according to the first unlocking password contained in the short message, the notification, the WeChat message, the QQ message and the like displayed on the screen locking interface. Or, the unlocking information may include a first unlocking password, and the first terminal may automatically recognize and fill the first unlocking password for unlocking. It should be understood that whether the first terminal displays the first unlocking password may also depend on the way in which the second terminal sends the unlocking message to the first terminal, and if the unlocking message is a short message, the first unlocking password is usually displayed, or if the unlocking message is other information, the first unlocking password may not be displayed.

If the first unlocking password is a sliding track, the first terminal can directly display the sliding track on the idle position of the unlocking interface except the unlocking password input interface of the received unlocking information, and a user refers to the input sliding track to unlock or automatically identifies the filling sliding track to unlock. If the first unlocking password is a fingerprint, the first terminal can directly and automatically identify the fingerprint to unlock.

(2) Fig. 4F is a schematic diagram of the unlocking of the first terminal. In fig. 4F, after the first terminal is unlocked according to the unlocking information, a screen locking password setting interface may be further displayed, and the user may reset the second unlocking password for the first terminal.

(3) Fig. 4G is a schematic diagram of unlocking the first terminal. In fig. 4G, the first terminal forcibly clears the first unlocking password according to the unlocking information, that is, the first terminal forcibly clears the previously set first unlocking password, and can directly enter the operation interface, and does not enter the screen locking state again before the password is reset next time.

(4) Fig. 4H is a schematic diagram of the first terminal unlocking. In fig. 4H, after the first terminal forcibly clears the first unlocking password according to the unlocking information, a screen locking password setting interface may also be displayed, and the user may reset the second unlocking password for the first terminal. Optionally, when the second unlocking password is reset, whether to reserve the trusted unlocking device may be selected, and if not, the trusted unlocking device may be deleted, and if so, the second terminal continues to be the trusted unlocking device of the first terminal. Further, the first terminal can also send the reset second unlocking password to the second terminal; the second terminal may receive the second unlocking password transmitted by the first terminal.

Optionally, displaying a reset lock screen password setting interface for the first terminal may include: and the first terminal displays a screen locking password setting interface after detecting unlocking according to the first unlocking password or forcibly clearing the first unlocking password. It should be understood that, in the above illustration, the unlocking password is mainly described by taking a sliding track as an example, and other unlocking manners are similar, and are not described again here.

In the embodiment of the application, a user can set the trusted unlocking device for the terminal device of the user, and when forgetting the unlocking password, the user can unlock the terminal device through the trusted unlocking device. The method for unlocking without clearing terminal data is provided for a user; the security of unlocking (such as a mobile phone bound to family) can be ensured by verifying the unique identification code of the trusted unlocking device.

Fig. 5 is a schematic flowchart of a method of unlocking a screen in an embodiment of the present application, and as shown in fig. 5, the method includes:

501. the first terminal sets an unlocking password.

In the embodiment of the application, the first terminal supports setting of the unlocking password, the screen locking state of the first terminal can be released by the set unlocking password, and the type of the applied unlocking password can include password unlocking of the types of a digital password, a sliding track, a fingerprint and the like. Specifically, reference may be made to any one of fig. 3A to 3C, which is not described herein again.

502. The first terminal generates a first scan code.

In the embodiment of the application, the first terminal may generate the first scan code when the unlocking password is set or modified. The first scanning code is used for bearing relevant information of an unlocking password of the first terminal, so that the first terminal can execute unlocking relevant operation when the first scanning code is scanned. The information carried by the first scan code includes, but is not limited to, the following descriptions:

(1) the information carried by the first scanning code may include a unique identification code of the first terminal and a first unlocking password of the first terminal, and the unique identification code of the first terminal is used for uniquely identifying the first terminal; the first unlocking password can unlock the screen locking state of the first terminal under the condition that the screen of the first terminal is locked, and the unique identification code of the first terminal is used for determining that the first scanning code is only the scanning code of the first terminal for unlocking the screen locking state.

(2) The information carried by the first scanning code comprises a user identifier and a first unlocking password of the first terminal, and the user identifier is used for uniquely identifying the user of the first terminal. For example, the user identifier may be authentication information (e.g., an identification number, a passport number, a social security number, etc.) of the user.

(3) The information carried by the first scanning code comprises a unique identification code of the first terminal, a user identification and a first unlocking password of the first terminal.

(4) The information carried by the first scanning code comprises first indication information for clearing the first unlocking password of the first terminal, namely, the first unlocking password of the first terminal can be cleared after the first terminal scans the first scanning code, so that the first terminal can remove the screen locking state.

(5) The information carried by the first scanning code comprises second indication information for skipping the first terminal to input the first unlocking password, namely, after the first terminal scans the first scanning code, an interface for inputting the first unlocking password can be automatically skipped, so that the screen locking state of the first terminal is released.

The first scan code may be a one-dimensional bar code, a two-dimensional code, a three-dimensional code, a four-dimensional code, or the like. Taking the first scan code as a two-dimensional code for example, the two-dimensional code may include an unlocking password and a unique identifier of the first terminal, and the unique identifier of the first terminal may be an identifier such as IMEI or SN. For example, fig. 6A is a schematic diagram of a first terminal generating a two-dimensional code. In fig. 6A, when the user sets the unlock password, prompt information may be generated, and the two-dimensional code may be generated according to a determination operation that the user clicks in the prompt information. For example, the unlock code is 123456 and the IMEI is 866369030001848, and the generated two-dimensional code may include both of these information. When the two-dimensional code is generated, the unique identification code of the first terminal can be automatically acquired, the unlocking password can be manually input by a user, or the first terminal can automatically acquire the unlocking password set or modified by the user.

It should be noted that there may be more than one two-dimensional code generated by the first terminal, and if the unlocking password is modified once, the first terminal generates one two-dimensional code, and may also prompt the last generated two-dimensional code to be invalidated, whether to delete or not, and thereby effectively ensure that the two-dimensional code displayed by the second terminal is the latest unlocking two-dimensional code, and the first terminal may be unlocked.

503. The first terminal sends a first scanning code to the electronic equipment.

In this embodiment, after the first terminal generates the first scanning code, the user may also fill in or select an account storing the first scanning code. If the filled account is a mailbox address, a network disk address and the like, the first terminal sends the first scanning code to the server, namely the electronic equipment is the server; if the filled account is a mobile phone number, a WeChat account, a QQ account, a microblog account and the like, the first terminal sends the first scanning code to the second terminal, namely the electronic equipment is the second terminal.

It should be understood that the first scan code is taken as a two-dimensional code, and the account storing the first scan code is described by taking a mailbox address as an example. Fig. 6B is a schematic diagram of the first terminal sending the two-dimensional code. In fig. 6B, the first terminal may directly transmit the two-dimensional code to the mailbox address "12345678 @ qq.com".

Optionally, the first terminal may also send a short message to a second terminal corresponding to the first mobile phone number in the mobile phone address list in a short message manner, where the short message may include a two-dimensional code; of course, the first contact corresponding to the first mobile phone number is generally a family, a friend, a classmate, and the like that the user thinks is relatively reliable.

For the wechat account, after the two-dimensional code is generated, a first wechat account for storing the two-dimensional code can be filled, and the first terminal sends the two-dimensional code to a second terminal for logging in the first wechat account. Fig. 6C is a schematic diagram of the first terminal sending the two-dimensional code. In fig. 6C, the user may not fill or save the account of the two-dimensional code, and after the first terminal generates the two-dimensional code, the user may perform a long-time pressing operation on the two-dimensional code. And the first terminal responds to the operation of the user for pressing the two-dimensional code for a long time (namely the time for pressing the two-dimensional code by the user exceeds a preset threshold), and displays a sent list, such as information, WeChat, QQ, Xinlang microblog, a payment treasure and the like. If the user clicks the WeChat, a WeChat friend list of the first terminal user can be displayed, the target friend is selected, and the two-dimensional code is sent to the target friend. It should be understood that the target friend may also be the account of the first terminal user, that is, the account of the first terminal user may be logged in on the second terminal to save or display the two-dimensional code.

It should be noted that step 503 is an optional step. Alternatively, after the first scan code is generated, the first terminal may print the first scan code and store the first scan code in a relatively secure place, such as a safe. When the user of the first terminal forgets the unlocking password, the first terminal can be used for scanning the first scanning code, and the screen locking state of the first terminal is released.

504. And the first terminal responds to the operation input by the user in the screen locking state and opens the code scanning application.

If the user forgets to unlock the password, the unlocking related operation can be executed according to the first scan code saved previously. In the embodiment of the present application, the information stored in the first scan code may be obtained by opening a viewfinder window of a code scanning application (e.g., a camera, a standalone code scanning application) and reading the first scan code. Illustratively, the user may implement the present functionality in several ways:

(1) fig. 6D is a schematic diagram of the first terminal opening the code scanning application. As shown in fig. 6D, the first terminal receives an unlocking password input by the user, the number of times of unlocking failure reaches an upper limit within a preset duration, the user may manually select to use the two-dimensional code unlocking function, and the first terminal opens the code scanning application in response to an operation selected by the user.

(2) Fig. 6E is a diagram illustrating that the first terminal opens the code scanning application. As shown in fig. 6E, the first terminal receives an unlocking password input by the user, the number of times of unlocking failure reaches an upper limit within a preset duration, and the first terminal is directly triggered to automatically open the code scanning application.

(3) Fig. 6F is a diagram illustrating the first terminal opening the code scanning application. In fig. 6F, the first terminal receives the unlocking password input by the user, the unlocking fails, the user may manually select to use the code scanning unlocking function, and the first terminal responds to the operation of the user to open the code scanning application.

(4) And the first terminal responds to the opening operation input by the user in the screen locking state and opens the code scanning application. For example: fig. 6G is a schematic diagram of the first terminal opening the code scanning application. In fig. 6G, the first terminal initially displays the password unlock input and the code scan unlock, and when the user selects the code scan unlock, the first terminal responds to the user operation to open the code scan application.

(5) When the first terminal is in a screen locking state, if the number of times of unlocking failure is greater than or equal to a preset threshold value, the first terminal presents user prompt information, and the user prompt information is used for prompting a user whether to open a code scanning application; and the first terminal acquires the operation of the user based on the user prompt information and opens the code scanning application.

(6) The method comprises the steps that a first terminal acquires identity authentication information input by a user in a screen locking state; and if the identity authentication information input by the user is matched with the preset identity authentication information, the first terminal opens the code scanning application. For example, the identity authentication information may be a privacy question, such as the name of the parent, favorite movie or the most impressive thing; or may require the user to enter a biometric for verification, etc.

It is understood that the first terminal releases the lock screen state in response to the code scanning operation of the code scanning application, which may be implemented by the following contents in step 505 and step 506, or may be implemented in other implementations, which are not limited in particular.

505. The second terminal displays the first scanning code.

The first scanning code may be stored in the second terminal or in the server. For example: the two-dimension code is stored in a mailbox address, a network disk address, a microblog account, a WeChat account and a QQ account; or in a gallery of the second terminal, or in a short message. The second terminal can check the short message sent by the first terminal to display the two-dimensional code; or the second terminal logs in the mailbox address and displays the two-dimensional code, as shown in fig. 6H, fig. 6H is a schematic diagram of the second terminal displaying the two-dimensional code; or the second terminal logs in other account numbers such as WeChat, QQ, Sino microblog and cloud, and the two-dimensional code sent by the first terminal is checked and displayed.

It should be understood that the timing of step 504 and step 505 is not limited, and step 505 is an optional step.

506. And the first terminal responds to the code scanning operation of the code scanning application and releases the screen locking state.

In the embodiment of the application, the object of the code scanning operation is a scanning code; the first terminal, in response to the code scanning operation of the code scanning application, releases the screen locking state, which may include: the first terminal responds to code scanning operation of code scanning application, and if information carried by the scanning code is matched with preset information, the screen locking state is released; the method may further comprise: and if the information carried by the scanning code is not matched with the preset information, the first terminal presents prompt information. The prompt message may be a scan code error or an alarm prompt.

Illustratively, the first terminal uses the scanning code application to scan the first scanning code displayed by the second terminal to release the screen locking state of the first terminal. Fig. 6I is a schematic diagram of the first terminal scanning the two-dimensional code. It should be understood that, in fig. 6I, the two-dimensional code includes the unlocking password and the unique identification code of the first terminal, the unique identification code of the first terminal may be determined again as the unlocking two-dimensional code of the first terminal, otherwise, there may be several terminals whose unlocking passwords are the same, and when only the unlocking password is included in the two-dimensional code, other terminals scan the two-dimensional code and may also unlock the two-dimensional code, which may not effectively guarantee the security thereof. The unlocking password of the first terminal can be unlocked.

Fig. 6J is a schematic diagram of unlocking when the first terminal scans the two-dimensional code, and as shown in fig. 6J, the first terminal opens the code scanning application in the screen locking state. And the first terminal scans the two-dimensional code to check the information, and if the check is successful, the first terminal can be automatically unlocked. Or fig. 6K is a schematic diagram of unlocking by scanning the two-dimensional code by the first terminal, as shown in fig. 6K, the first terminal scans the two-dimensional code to perform information verification, and if the verification is successful, the password resetting interface is automatically jumped out, and the user can reset a new unlocking password. If the verification fails, the verification information can be prompted to be unmatched, and other operations are not carried out.

Optionally, if the information carried in the two-dimensional code includes second indication information for skipping the first terminal to input the first unlocking password, after the first terminal scans the first scanning code, the interface for inputting the first unlocking password may be automatically skipped, so as to release the screen locking state of the first terminal.

It should be understood that a threshold value may also be set for the number of times the first terminal scans the two-dimensional code without unlocking. For example, the first terminal scans the two-dimensional code for 5 times continuously, and is not unlocked yet, then, in the next 3 hours, the function of unlocking by scanning the two-dimensional code is prohibited, and a lawbreaker is prevented from maliciously using the function of unlocking by scanning the two-dimensional code to acquire user information.

In a possible implementation manner, when the code scanning application is opened, the first terminal can send a two-dimensional code request to the second terminal, the second terminal can send the two-dimensional code to the first terminal according to the two-dimensional code request, and when the first terminal receives a two-dimensional code picture, the two-dimensional code can be automatically scanned and identified, so that unlocking is performed. The problem that only the first terminal is available and the second terminal does not exist to display the two-dimensional code at present, so that the first terminal cannot be unlocked can be effectively solved.

Optionally, if the first unlocking password of the first terminal is updated to the second unlocking password, the first terminal generates a second scanning code according to the second unlocking password and the unique identification code of the first terminal; or the first terminal updates the first scanning code periodically according to the current unlocking password and the unique identification code of the first terminal to generate a third scanning code. The regenerated second scan code or third scan code may be automatically or manually selected by the user to be sent to the second terminal or server.

It should be noted that, in a possible implementation manner, the code scanning application may be other applications such as a camera, that is, the camera has functions of scanning a barcode, a two-dimensional code, a three-dimensional code, a four-dimensional code, and the like.

In the embodiment of the application, a user can generate a unique scanning code for the terminal of the user, and the scanning code can be a bar code, a two-dimensional code, a three-dimensional code, a four-dimensional code and the like. In the above embodiments, the two-dimensional code is mainly used as an example for explanation, and other scan codes are similar. The scanning code comprises the unique identification code and the unlocking password of the first terminal, so that the user can perform unlocking operation by scanning the two-dimensional code when forgetting to unlock the password. The method provides a way for unlocking without clearing terminal data when the user forgets the unlocking password; the method for generating the two-dimensional code by using the unlocking password and the unique identification code of the terminal ensures the uniqueness of the unlocking secret key and improves the unlocking safety.

Fig. 7 is a schematic diagram of an embodiment of a method for unlocking a screen in an embodiment of the present application, where the method includes:

701. the first terminal sets an unlocking password.

In the embodiment of the application, the first terminal supports setting of the unlocking password, the screen locking state of the first terminal can be released by the set unlocking password, and the type of the applied unlocking password can include password unlocking of the types of a digital password, a sliding track, a fingerprint and the like. The first terminal may set or modify the unlocking password, which may specifically refer to any one of fig. 3A to 3C, and details are not described here.

702. The first terminal sets a second terminal connected with the first terminal as a trust unlocking device.

In the embodiment of the present application, the first terminal takes a mobile phone as an example, and the second terminal takes a smart watch as an example for description. Fig. 8A is a schematic diagram of a mobile phone setting a connected smart watch as a trusted unlocking device in a setup. In fig. 8A, the mobile phone may first establish a bluetooth connection with the smart watch, and then set the smart watch as a trusted unlocking device of the mobile phone in the setup. Fig. 8B is a schematic diagram of the mobile phone setting the connected smart watch as a trusted unlocking device in the smart watch application. In fig. 8B, the APP of the smart watch is installed on the mobile phone, and the user can open the application of the smart watch installed on the mobile phone and set the smart watch as the trusted unlocking device of the mobile phone.

Or when the unlocking password of the mobile phone is initially set, the smart watch connected with the mobile phone can be set as a trusted unlocking device of the mobile phone; or, after the mobile phone has been set with the unlocking password, after a period of time, the user may enter the setting interface again in consideration of actual needs, and set the smart watch connected with the mobile phone as the trusted unlocking device of the mobile phone.

It should be understood that the connection with the first terminal here may refer to a scenario that the first terminal and the second terminal are bluetooth-connected or USB-connected, or a scenario that the first terminal and the second terminal have bluetooth-connected before or USB-connected before. Optionally, after the first terminal sets the second terminal as the trusted unlocking device, an indication message may be sent to the second terminal, where the indication message includes a bluetooth address of the first terminal, and the indication message is used to inform that the second terminal is the unlocking device of the first terminal, and the first terminal may be unlocked.

Optionally, when the first terminal sets the second terminal connected to the first terminal as the trusted unlocking device, the first unlocking password of the first terminal may also be sent to the second terminal.

It should be noted that each bluetooth enabled device has a bluetooth address. When the mobile phone establishes Bluetooth connection with other terminals, the mobile phone can store the Bluetooth address of each terminal, and if the mobile phone sets one or more terminals establishing Bluetooth connection as trusted unlocking equipment, the mobile phone can correspondingly store an identifier or indication information. As shown in table 1 below, the handset stores the bluetooth address of the device that establishes a bluetooth connection with the handset and exemplary information of whether it is a trusted unlock device.

Bluetooth address of connected device	Unlocking a device for trust
		EB：F3：AC：F6：E9：17	Is that
FC：F5：EC：E6：R9：50	Whether or not
		AM：E5：BC：N6：R7：35	Whether or not

TABLE 1

Optionally, the corresponding device type, such as a mobile phone, a bracelet, a notebook, etc., may also be included in table 1, which is not limited herein.

703. The first terminal acquires unlocking information.

In this embodiment of the application, the unlocking information acquired by the first terminal may be an unlocking request sent by the first terminal to the second terminal, the unlocking information sent by the second terminal to the first terminal according to the unlocking request, or the unlocking information actively sent by the second terminal to the first terminal, and the first terminal is not required to send the unlocking request.

The method for sending the unlocking request to the second terminal by the first terminal includes, but is not limited to, the following implementation manners:

(1) in the screen locking state, the first terminal responds to an unlocking operation input by a user, and determines that the trusted unlocking device of the first terminal is the second terminal according to the table 1, and sends an unlocking request (shown in fig. 4C) to the second terminal, and the second terminal feeds back unlocking information according to the unlocking request.

(2) In the screen-locking state, if the number of times of unlocking failure is greater than or equal to a first preset threshold, the first terminal automatically sends an unlocking request to the second terminal (see fig. 4A).

(3) In the screen-locked state, if the unlocking fails, the first terminal sends an unlocking request to the second terminal in response to an unlocking operation input by the user (see fig. 4B).

(4) When the first terminal is in a screen locking state, if the number of times of unlocking failure is larger than or equal to a first preset threshold value, the first terminal presents first prompt information, the first prompt information is used for prompting a user whether to send an unlocking request to the second terminal, and the first terminal acquires the operation of the user based on the first prompt information and sends the unlocking request to the second terminal.

(5) And if the first terminal detects the second terminal within a preset range in the screen locking state, the first terminal sends an unlocking request to the second terminal.

(6) And if the first terminal detects that the duration of the second terminal is greater than or equal to a second preset threshold value in a preset range in the screen locking state, the first terminal sends an unlocking request to the second terminal.

(7) The first terminal presents second prompt information in a screen locking state, the second prompt information comprises contact ways of at least two contacts, and the second prompt information is used for prompting a user to select the contact to be sent with an unlocking request; the method comprises the steps that a first terminal obtains selection operation input by a user; if the contact person targeted by the selection operation is a preset contact person, the first terminal sends an unlocking request to a second terminal, and the second terminal is a terminal corresponding to the preset contact person; and if the contact person targeted by the selection operation is not the preset contact person, triggering an alarm prompt by the first terminal.

It should be understood that the unlocking request includes a bluetooth address of the first terminal, and when the second terminal can authenticate whether to establish the trusted unlocking device with the first terminal, the bluetooth addresses included in the indication information sent to the second terminal are the same, and if the bluetooth addresses are the same, the second terminal sends the unlocking information to the first terminal.

The second terminal sends the unlocking information to the first terminal, and the method may further include:

(1) and the second terminal receives the unlocking operation input by the user and sends unlocking information to the first terminal. For example: fig. 8C is a schematic diagram of the smart watch sending unlocking information to the mobile phone. It should be understood that, in fig. 8C, the unlocking identifier is an identifier capable of unlocking the mobile phone, the user clicks the unlocking identifier, the second terminal responds to the clicking operation of the user, pops up a prompt message, and confirms to the user whether to send the unlocking message to the mobile phone again. If the user selects 'yes', the second terminal sends unlocking information to the first terminal; and the first terminal receives unlocking information in a screen locking state. When the first terminal receives the unlocking information, whether the second terminal is the connected trusted unlocking device set by the first terminal or not can be determined according to the table 1, and if yes, the first terminal uses the unlocking information to unlock.

(2) And if the second terminal detects the first terminal in the preset range, the second terminal sends unlocking information to the first terminal.

(3) And if the second terminal detects that the duration of the first terminal is greater than a preset threshold value in a preset range, the second terminal sends unlocking information to the first terminal.

For example: fig. 8D is a schematic diagram of the distance between the mobile phone and the smart watch being within a preset range. In fig. 8D, when the second terminal detects the first terminal within the preset distance range (L), or detects that the duration of the first terminal reaches a preset threshold, the second terminal sends unlocking information to the first terminal, and the first terminal receives the unlocking information in the screen-locked state; when the first terminal receives the unlocking information, whether the second terminal is the connected trusted unlocking device set by the first terminal or not can be determined according to the table 1, and if yes, the first terminal uses the unlocking information to unlock.

Or, when the first terminal detects the second terminal within a preset range (L) in the screen-locked state, or detects that the duration of the second terminal reaches a preset threshold, it may be determined that the trusted unlocking device of the first terminal is the second terminal according to table 1, and send an unlocking request to the second terminal, where the second terminal feeds back unlocking information according to the unlocking request.

Optionally, the unlocking information may include a first unlocking password of the first terminal, and the first unlocking password is used for unlocking the first terminal; or the unlocking information may include a first unlocking password of the first terminal, and a screen locking password setting interface is displayed after the first terminal is unlocked, wherein the screen locking password setting interface is used for a user to reset the unlocking password; or the unlocking information is used for forcibly clearing the first unlocking password of the first terminal, namely clearing the unlocking password of the first terminal and entering an operation interface; or the unlocking information is used for forcibly clearing the first unlocking password of the first terminal and then displaying a screen locking password setting interface, and the screen locking password setting interface is used for the user to reset the second unlocking password.

It should be noted that, when the first terminal sends an unlocking request to the second terminal, or the second terminal sends unlocking information to the first terminal, the first terminal and the second terminal are in a state where bluetooth is being connected.

704. And the first terminal responds to the unlocking information and executes the relevant operation of releasing the screen locking state.

In this embodiment of the application, the first terminal responds to the unlocking information to perform a relevant operation of releasing the lock screen state, which may include but is not limited to the following implementation manners:

(1) if the unlocking information includes a first unlocking password of the first terminal, the first terminal can be unlocked using the first unlocking password. Specifically, refer to fig. 4E, which is not described herein again.

(2) If the unlocking information comprises a first unlocking password of the first terminal and indication information for resetting the unlocking password, the first terminal can use the unlocking information to unlock and display a screen locking password setting interface, and a user can reset a second unlocking password. Specifically, reference may be made to fig. 4F, which is not described herein again.

(3) The first terminal may clear the first unlocking password using the unlocking information if the unlocking information includes indication information to clear the unlocking password. Specifically, reference may be made to fig. 4G, which is not described herein again.

(4) If the unlocking information comprises the indication information for clearing the unlocking password and the indication information for resetting the unlocking password, the first terminal can use the unlocking information to clear the first unlocking password and display a screen locking password setting interface, and the user can reset the second unlocking password. Specifically, refer to fig. 4H, which is not described herein again.

It should be noted that after receiving the unlocking information, the first terminal may further identify whether the smart watch is a connected device set to trust for unlocking, and may unlock the smart watch only if the verification is successful; or resetting the password after unlocking, or clearing the password, or resetting the password after clearing the password. That is, the bluetooth address of the second terminal may also be included in the unlocking information.

Fig. 8E is a schematic diagram illustrating whether the unlocking is performed by the smart watch on the first terminal. It should be understood that the unlocking information sent by the second terminal to the first terminal may not be actively requested by the first terminal, in this case, as shown in fig. 8E, when the first terminal receives the unlocking information, a prompt message may be given to the user, such as "whether to unlock through the smart watch? "and the like, to ensure the security of the first end-user information.

In the embodiment of the application, when the user forgets the unlocking password, the unlocking can be performed through the trusted unlocking device connected with the terminal. A feasible scheme is provided for forgetting the unlocking password, and the unlocking password can be cleared without clearing user data on the terminal or reset after clearing the unlocking password; according to the method and the device, the problem that the user forgets the unlocking password of the terminal can be safely and effectively solved by authorizing the unlocking of the connected terminal (such as a bracelet, an intelligent watch and the like).

In a possible implementation manner, if the first terminal receives unlocking information sent by the second terminal in a black screen state, the unlocking information comprises a unique identification code and an unlocking password of the first terminal, and the unlocking password is used for removing the screen locking state of the first terminal; the first terminal can respond to the unlocking information sent by the second terminal, light the screen, enter a screen locking state, present a screen locking interface and automatically fill an unlocking password in the screen locking interface; the first terminal releases the screen locking state.

In a possible implementation manner, if the first terminal detects that the second terminal is within a preset distance range (such as 5cm), the first terminal sends an unlocking request to the second terminal, wherein the unlocking request is used for requesting the second terminal to release the screen locking state of the first terminal, and the first request comprises a unique identification code of the first terminal and a unique identification code of the second terminal; the method comprises the steps that a first terminal receives unlocking information sent by a second terminal, the unlocking information is response of the second terminal to an unlocking request, the unlocking information comprises a unique identification code and an unlocking password of the second terminal, and the unlocking password is used for releasing the screen locking state of the first terminal; and responding to the received unlocking information, the first terminal presents a screen locking interface, an unlocking password is automatically filled in the screen locking interface, and the screen locking state is released.

Optionally, if the first terminal monitors that the second terminal is within the preset distance range, the automatically sending, by the first terminal, the unlocking request to the second terminal may include: and if the first terminal detects that the second terminal is in the preset distance range and the duration of the second terminal in the preset distance range is greater than the preset time threshold, the first terminal sends an unlocking request to the second terminal.
