Description

Screen locking control method, device, system, equipment and medium for computer equipment

Technical Field

The present invention relates to the field of screen lock applications, and in particular, to a screen lock control method, apparatus, system, device, and medium for a computer device.

Background

With the continuous development of computer technology, the application range of computer equipment is wider and wider, and the privacy and important data of users are inevitably involved. To protect the privacy and important data of the user, the computer device may be locked without the user using the computer device. And when the user needs to use the computer, the computer equipment is unlocked, so that the protection of privacy and important data can be realized through screen locking control.

However, in some scenarios, the computer devices running different computer modules can be switched, and the executed lock screen control has a big problem, which is described in detail below:

the computer equipment can be loaded with a plurality of computer modules, wherein one computer module is respectively connected with other computer modules through different display channels. The display channel mentioned here is matched with the connected computer module, such as: the connected computer module is a built-in PC module (the PC module refers to a computer module with an operating system of a windows system), the display channel is a PC channel, the connected computer module is an external PC module, and the display channel is a VGA channel or an HDMI channel.

The currently running computer module can lock the screen of the computer device through the screen locking application of the computer module per se under the condition that the user A does not use the computer device for the privacy and important data of the user A. However, the screen locking operation executed by the application only has a limiting effect on the system environment of the user and has no influence on other computer modules, and if the user B switches to another computer module for using the computer equipment next time, the privacy and important data of the user A are likely to be seen through the switched computer module.

Therefore, screen locking control of computer equipment with different computer modules can be switched to operate, so that the problems of low safety and easy exposure of privacy and important data of users exist.

It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present invention. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

The computer device according to the embodiment of the present invention is provided with at least two computer modules. To facilitate the distinction between different computer modules, in one example, a computer module for performing the basic functions of a computer device may be referred to as a main computer module; the computer modules introduced to accommodate particular scenario requirements are referred to as secondary computer modules. In other examples, the main computer module and the sub-computer module may be further divided according to other principles, which is not limited in this embodiment of the present invention.

When the computer equipment carrying a plurality of computer modules protects the privacy and important data of a user, in order to avoid exposing the privacy of the user after switching the computer modules, the screen of each computer module needs to be locked by the screen locking application of each computer module, so that the operation is extremely complicated. The embodiment of the invention discloses a screen locking control method, a device, a system, equipment and storage, aiming at protecting privacy and important data of a user and reducing the complexity of screen locking operation.

The screen locking control method disclosed by the embodiment of the invention is applied to a secondary computer module carried by computer equipment, generates a screen locking starting instruction when a screen locking condition is met, sends the screen locking starting instruction to a screen locking application of a primary computer module carried by the computer equipment, and can control the screen locking application to output a screen locking interface by the screen locking starting instruction sent to the screen locking application. Because the display level of the output content of the main computer module is higher than that of the auxiliary computer module, the display level of the screen locking interface output by the screen locking application can be higher than that of the auxiliary computer module, the effect of top display is achieved, and the computer equipment can be used after the screen is unlocked no matter whether the computer module operated by the computer equipment is switched or not. Compared with the related screen locking control technology, the auxiliary computer module does not need to be independently provided with screen locking application, and each computer module can achieve the purpose of locking other computer modules through controlling the screen locking application of the main computer module. The following first introduces a system for realizing the screen locking control method of the present invention with reference to the accompanying drawings:

referring to fig. 1A, the lock screen control system shown in fig. 1A may include a computer device 100, where the computer device 100 may be loaded with a main computer module 110 and a sub-computer module 120, the sub-computer module 120 includes a lock screen control module 121, and the main computer module 110 includes a lock screen module 111.

The host computer module 120 belongs to the computer device 100, is built in the computer device, and may include various components of the host computer of the computer device 100, and may be used to execute the basic functions of the computer device 100 and other functions meeting the user's needs. The basic functions and other functions mentioned here are different depending on the device usage of the computer device, and the embodiment of the present invention is not limited to this, for example, the computer device is an intelligent interactive tablet, and other functions are as follows: switching the currently running secondary computer module, forwarding the touch data to the secondary computer module, and the like. The basic functions are as follows: touch control, display control, and the like.

In order to ensure the normal display function of the computer device 100, the designer considers that the main computer module 110 performs the display control function of the computer device 100, and the display level of the output content of the main computer module 110 can be higher than that of the sub-computer module 120 through software and hardware presetting. For example, the display policy of the whole computer architecture display system of the computer device 100 presets the output content of the main computer module 110 to be output to the graphics layer, the output content of the sub-computer module 120 to be output to the video layer, the graphics layer is located above the video layer, and if the graphics layer needs to display an interface, the graphics layer is displayed above the video layer, so as to form a top-setting effect. The screen locking module 111 outputs a screen locking interface, and can output the screen locking interface to the graphic layer by default to achieve the effect of top placement.

In the embodiment of the present invention, in view of the characteristic that the display level of the output content of the main computer module 110 is higher than that of the sub-computer module 120, the lock screen module 111 may be configured only in the main computer module 110, and the lock screen control module 121 may be configured in the sub-computer module 120.

The screen locking module 111 is a software program module, corresponds to a program code of a screen locking application, and is configured to lock a screen of the computer device 100, and may be formed by reading, by a processor (which may refer to a processor of a motherboard, an MCU, or a processor of another chip) of the main computer module 110, a corresponding computer program instruction in a readable storage medium such as a nonvolatile memory into an internal memory for running. In practical applications, after receiving the screen locking control instruction sent by the secondary computer module 120, the primary computer module 110 will control the processor to read the corresponding computer program instruction in the readable storage medium such as the non-volatile memory into the content for operation, so as to form the screen locking module 111. The screen locking control command mentioned here may be a screen locking start command, a screen locking close command, or other commands related to screen locking or unlocking.

The sub-computer module 120 that transmits the lock screen control instruction may be a computer module that is mounted on the computer apparatus 100 to meet its particular scene. The secondary computer module 120 may be built into the computer device 100 or may be external to the computer device 100. In one example, the secondary computer module 120 may be hot-plugged into the interface device corresponding to the primary computer device 100 when it is built into the computer device 100. In another example, when the sub-computer module 120 is externally disposed on the computer device 100, it can be connected to the computer device 100 through a corresponding connecting line, and can also be connected to the computer device 100 in a wireless manner through a peripheral device.

In addition, there may be more than two sub-computer modules 120 installed in the computer device 100, and the specific number is determined according to the requirements of the application scenario of the computer device 100. Different sub-computer modules 120 are respectively connected with the main computer module 110, and in order to realize the screen locking control, screen locking control instructions can be respectively sent to the main computer module 110. Wherein, the lock screen control instruction is generated by the lock screen control module 121 contained in the secondary computer module 120.

The screen locking control module 121 is a software program module, corresponds to a program code of a screen locking control application or a screen locking control plug-in, and is configured to control the screen locking module 111 of the main computer module 110 to lock a screen, and may be formed by reading, by the processor of the sub-computer module 120, a corresponding computer program instruction in a readable storage medium such as a non-volatile memory into an internal memory for operation. In practical applications, after the screen locking control condition is satisfied, the sub-computer module 120 controls the processor to read the corresponding computer program instructions in the readable storage medium such as the non-volatile memory into the content for operation, so as to form the screen locking control module 121. The lock screen control condition mentioned here may be a lock screen condition for triggering lock screen activation, an unlock condition for triggering lock screen deactivation, or other lock screen related conditions. After the screen locking control condition is satisfied, the screen locking control module 121 generates a corresponding screen locking control instruction, and sends the screen locking control instruction to the screen locking module 111 through the connection channel between the secondary computer module 120 and the primary computer module 110.

In practical application, in order to protect the privacy and important data of a user, the embodiment of the present invention may determine that a screen locking condition is satisfied when a touch operation of the user is detected, a predetermined time is reached, or another trigger event for triggering screen locking is detected, and the screen locking control module 121 generates a screen locking start instruction and sends the screen locking start instruction to the screen locking module 111. Specifically, when the lock screen start instruction is transmitted, the lock screen start instruction is transmitted through a connection channel between the sub-computer module 120 and the main computer module 110. The screen locking module 121 receives the screen locking starting instruction and outputs a screen locking interface displayed on the top. The screen locking interface may be randomly selected from a preset screen locking interface library, or after the selection is triggered by the user of the secondary computer module 120, the identifier of the selected screen locking interface may be sent to the screen locking module 111 along with a screen locking start instruction.

In addition, the time when the screen locking module 121 outputs the screen locking interface may be preset, or may be triggered by the user of the secondary computer module 120, and the triggered time information may be sent to the screen locking module 111 along with the screen locking start instruction. The time for outputting the screen locking interface may be different according to the application scenario and the preset after receiving the screen locking start instruction, or when the computer device continues for a predetermined time and is not used by the user, and is not limited herein.

Compared with the related screen locking control technology, the auxiliary computer module does not need to be independently provided with screen locking application, and each computer module can achieve the purpose of locking other computer modules through controlling the screen locking application of the main computer module.

After the screen is locked, if unlocking is needed subsequently, the embodiment of the invention can unlock the screen by the screen locking application of the main computer module according to a corresponding unlocking mode according to the existing unlocking method. However, the embodiment of the present invention further provides different unlocking methods, which are executed by the screen locking control application or the screen locking control plug-in of the secondary computer module, and the following describes in detail the detailed unlocking process in the screen locking control method according to the embodiment of the present invention in combination with the screen locking control system:

referring to fig. 3, fig. 3 is a flowchart illustrating a screen locking control method of a computer device according to another exemplary embodiment of the present invention.

The computer device related to the screen locking control method shown in fig. 3 may be the computer device in any embodiment of fig. 1A to 1F, the computer device is equipped with a main computer module and a sub-computer module, and the method shown in fig. 3 may be applied to the sub-computer module, and includes the following steps S301 to S303:

Before verifying the acquired unlocking data, the embodiment of the present invention may execute the step of acquiring the unlocking data, where the manner of acquiring the unlocking data is determined by a predetermined unlocking manner and a currently operating computer module, and the following are some examples:

first, the unlocking method is password unlocking. If the unlocking password is a pattern or a character, in one example, the unlocking password can be input into the main computer module through a screen locking interface or a key on a keyboard, and then the main computer module is switched to a screen locking control application of the auxiliary computer module to complete the acquisition of the unlocking data. The specific unlocking process can be seen in fig. 4:

The screen locking application can send the password to the screen locking control application or the plug-in of the secondary computer module (step S42), the screen locking control application or the plug-in verifies the received password after receiving the input password (step S43), and during specific verification, the received password can be compared with a prestored unlocking password, if the received password is consistent with the prestored unlocking password, the verification is successful, and if the received password is inconsistent with the prestored unlocking password, the verification fails.

After the verification is successful, the screen locking control application or the plug-in generates a screen locking closing instruction and sends the screen locking closing instruction to the screen locking application (step S44), the screen locking application unlocks after receiving the instruction (step S45), and in some cases, the screen locking application can return an unlocking result to the screen locking control application or the plug-in (step S46).

In this example, the manner in which the screen locking application and the screen locking control application transmit data or instructions may refer to the embodiments shown in fig. 1A to fig. 1F, and is not described herein again.

In addition, when the method is applied to a specific scene, such as an intelligent teaching scene, a user can be a teacher, a main computer module can be an android module, an auxiliary computer module can be a PC module and can be plugged, and a server can be a C + +/web background.

In another example, the password is biological data such as audio, fingerprint, iris, face, etc., the screen locking interface of the embodiment of the present invention may include a UI interface for identifying the biological data, after the user triggers a corresponding identification manner on the UI interface, the screen locking module calls a corresponding biological data acquisition device, such as a microphone array, a fingerprint sensor, a camera, etc., after the identified biological data, in order to improve the unlocking efficiency, the screen locking application may directly perform verification, and after the verification passes, the biological data is directly unlocked; if the unlocking efficiency is not intended, the recognized biological data can be transmitted to the screen locking control application or the plug-in of the secondary computer module for verification, a screen locking closing instruction is generated after the verification is passed, and the screen locking closing instruction is sent to the screen locking application to realize unlocking.

In other examples, in order to improve the unlocking efficiency and verify the biometric data by the lock screen control application, the unlocking may be performed in the following manner, specifically referring to fig. 5:

the user triggers a corresponding biometric data recognition mode on the UI interface (step S51), which may be a biometric data recognition mode such as an audio recognition mode, a fingerprint recognition mode, an iris recognition mode, a face recognition mode, etc., and is not limited herein.

The lock screen application sends a notification to the lock screen control application or plug-in through which biometric data recognition is performed after detecting the trigger (step S52).

After receiving the biological data identification notification sent by the screen locking application, the screen locking control application or the plug-in generates and outputs a biological data identification interface displayed on the top (S53), and sends a request for temporarily closing the screen locking interface to the screen locking application (S54);

after receiving the request, the screen locking application temporarily removes the screen locking interface and switches and displays the output content of the secondary computer module (S55), wherein the specific switching can inform the operating system of the primary computer module to switch, and the biological data identification interface can be displayed after the switching.

The screen locking control application or the plug-in acquires the biological data (S56), and when the screen locking control application or the plug-in acquires the biological data, the biological data acquisition device is informed to acquire the biological data, the biological data sent by the biological data acquisition device is received, and the biological characteristic data is extracted from the biological data to be unlocking data.

The lock screen control application or plug-in then notifies the lock screen application to output the top displayed lock screen interface (S57).

Furthermore, the lock screen control application or the plug-in may authenticate the extracted biometric data by itself (S58), and after the authentication is successful, generate a lock screen closing instruction and send the lock screen closing instruction to the lock screen application (S59), and after the lock screen application receives the instruction, cancel the unlock interface and unlock (step S510).

In other examples, the screen locking control application or the plug-in can also send the biometric data to the server for verification, the server returns a verification result after verification, the screen locking control application or the plug-in confirms whether the unlocking number is verified successfully or not according to the verification result, a screen locking closing instruction is successfully sent to the screen locking application, and the screen locking application unlocks after receiving the instruction.

And secondly, the unlocking mode is unlocking of the unlocking device, the preset unlocking mode is unlocking of the unlocking device, the unlocking device can be a U disk, an NFC card and the like, and unlocking data are stored in the unlocking device. When unlocking is needed, the unlocking device can be connected with the main computer module or the auxiliary computer module in a wired or wireless mode.

In an example, before performing a verification operation on the acquired unlocking data, the embodiment of the present invention may acquire the unlocking data by:

decrypting the unlocking file by adopting a preset decryption algorithm;

Further, the verification operation may be performed on the acquired unlock data by:

sending the extracted unlocking data to an associated server; the specific form of the server may be determined by the unlocking data or the application scenario, which is not described herein again, and reference may be made to the embodiment related to fig. 1E.

In the above embodiment, after the verification is successful, a screen locking closing instruction may be generated and sent to the screen locking application, and the screen locking application is controlled to cancel the screen locking interface displayed on the top, which is output by the screen locking application, so as to achieve unlocking.

In some cases, considering that a network between the computer device and the server may be offline, in order to ensure successful unlocking through the unlocking device during offline, after the unlocking data is successfully verified, the embodiment of the invention may further cache the extracted unlocking data as verification data to the local; if the unlocking file in the unlocking device is read again and decrypted successfully, the unlocking data is extracted from the decrypted unlocking file, and if the network between the unlocking file and the server is unavailable, the extracted unlocking data is compared with the locally cached verification data; if so, the verification is determined to be successful.

In addition, in some examples, the unlocking data includes login data, user permission data, and an identity of the unlocking device, and after the unlocking data is extracted, the login data may be sent to the login server, the user permission data and the identity of the unlocking device may be sent to the permission verification server, and if the sending fails or a returned verification result is not received within a predetermined time, it is determined that the network with the server is unavailable.

In one example, to improve the security of locking the screen, the locally cached verification data may be updated or the unlock file in the device may be unlocked after the computer device is unlocked.

In another example, in order to avoid the problem that the local cache check file is invalid due to the recovery software, when the check data is updated each time, the updated check data can be synchronously stored in the partition of the local hard disk, and the update time is recorded; when the extracted unlocking data is compared with the locally cached check data, the locally cached check data can be replaced by the latest stored check data of the partition of the local hard disk according to the recorded updating time; and comparing the extracted unlocking data with the replaced verification data. After the operation, as long as not all the partitions are restored, the offline unlocking can be normally used.

Whether the locally cached check data is consistent with the latest check data stored in the partition of the local hard disk or not can be judged; if the unlocking data is consistent with the verification data, the extracted unlocking data is compared with the verification data cached locally; and if the unlocking data are inconsistent, comparing the extracted unlocking data with the latest stored check data of the partition of the local hard disk.

In other cases, the unlocking data includes login data, and in order to improve login efficiency of the relevant application in the secondary computer module, the embodiment of the present invention may further send the login data to the relevant application, so that the relevant application logs in the login server. Therefore, the unlocking can be realized while one-key login is realized.

The following may be said to unlock the unlocking device in conjunction with fig. 6 and the primary and secondary computer modules:

if the unlocking device is connected with the secondary computer module, the secondary computer module reads the unlocking file in the unlocking device and then sends the unlocking file to the screen locking control application or the plug-in (step S61). In this example, the unlocking device is taken as a usb disk as an example.

If the unlocking device is connected to the host computer module, the host computer module reads the unlocking file in the unlocking device (step S62), and then sends the unlocking file to the screen locking application, and the screen locking application sends the unlocking file to the screen locking control application or the plug-in (step S63).

After receiving the unlocking file, the screen locking control application or the plug-in can decrypt the unlocking file by adopting a preset decryption algorithm; if the decryption is successful, the unlock data is extracted from the decrypted unlock file (S64). If the decryption fails, the unlocking device is indicated to have no unlocking authority, and the unlocking is forbidden. The unlocking file can be encrypted by adopting an AES (advanced encryption standard) encryption algorithm of serial number information of the unlocking device, so that the unlocking file in the unlocking device is prevented from being copied, and the decryption adopts a corresponding decryption algorithm.

After the unlocking data is extracted, in an example, the screen locking control application or the plug-in may compare the unlocking data with the unlocking data pre-stored in the screen locking control application or the plug-in.

In some examples, the screen locking control application or the plug-in may send unlocking data to the server, the server sends a verification result to the screen locking control application or the plug-in after verifying the unlocking data, and the screen locking control application or the plug-in determines whether the verification of the unlocking data is successful according to a returned verification notification.

It should be noted that the unlocking data may be the aforementioned character password, and may also include at least one of the related login data, the user right data, and the identification of the unlocking device. Specifically, reference may be made to the embodiment shown in fig. 1E, which is not described herein again.

In addition, the server may have different implementation manners for different unlocking data, for example, the unlocking data only includes login data, and the server may be a login server to verify the login data.

For another example, the unlocking data includes user permission data and an identity of the unlocking device, and the server may be a permission verification server, and it is sufficient to verify the user permission data and the identity of the unlocking device.

Fig. 6 of the embodiment of the present invention illustrates that, for a case where the unlocking data includes login data, user right data, and an identity of the unlocking device, the server may include a login server and a right verification server.

After the unlocking data is extracted by the screen locking control application or the plug-in, login data may be sent to the login server (step S65), and the login server performs login verification on the login data and returns a verification result (step S66). The screen locking control application or the plug-in confirms whether login verification is successful according to a verification result, if not, the screen locking device is connected with the main computer module, the screen locking control application or the plug-in sends a screen locking file to be updated to the screen locking application (S67), the screen locking application prompts the screen locking device to update the screen locking file (S68), the screen locking device is connected with the main computer module again after updating the screen locking file, the main computer module reads an unlocking file in the unlocking device and sends the unlocking file to the screen locking application, the screen locking application sends the unlocking file to the screen locking control application or the plug-in (S69), and the screen locking control application or the plug-in can decrypt the unlocking file by adopting a preset decryption algorithm after receiving the unlocking file; if the decryption is successful, the unlocking data is extracted from the decrypted unlocking file (S610).

The lock screen control application or the plug-in may send login data to the login server again (step S611), and the login server performs login authentication on the login data (step S612), and returns an authentication result (step S613). And the screen locking control application or the plug-in confirms whether the login verification is successful according to the verification result, if so, authority data are sent to an authority verification server, the authority data comprise the user authority data and the identity (S614), the authority verification server performs authority verification, the user authority data and the identity are subjected to authority verification (step S615), and the verification result is returned (S616).

And the screen locking control application or the plug-in confirms whether the authority verification is successful according to the verification result, if so, a screen locking closing instruction is generated and sent to the screen locking application (S617), and the screen locking application cancels the screen locking interface after receiving the screen locking instruction and unlocks the screen locking interface (S618).

In addition, if the screen locking control application or the plug-in sends the login data to the login server for the first time, the login authentication is confirmed to be successful according to the returned authentication result, and the user permission data and the identity can be directly sent to the permission authentication server. And the authority verification server performs authority verification on the user authority data and the identity identification and returns a verification result. And the screen locking control application or the plug-in confirms whether the authority verification is successful according to the verification result, if so, a screen locking closing instruction is generated and sent to the screen locking application, and the screen locking application receives the screen locking interface which is cancelled and unlocks.

And thirdly, the preset unlocking mode is code scanning unlocking, wherein code scanning is code scanning by a user terminal, the user terminal can be a smart phone, a tablet computer, a PDA or other handheld devices with a code scanning function, and the scanned graph can be a two-dimensional code or a bar code with other dimensions, which is not limited herein.

In an example, the unlocking data includes user right data, and before performing a verification operation on the acquired unlocking data, the embodiment of the present invention may acquire the unlocking data through the following operations:

and responding to an unlocking trigger condition, and requesting the unlocking graphic code and the access token from the login server.

And receiving the graphic code and the access token returned by the login server.

And sending the graphic code to a screen locking application of a main computer module so as to control the screen locking application to output the graphic code to a screen locking interface.

And sending an authority data request carrying the access token to the login server.

Furthermore, the screen locking control application or the plug-in can directly verify the user permission data and also can send the user permission data to the permission verification server, the permission verification server returns a verification result after verification, and the screen locking control application or the plug-in can confirm whether the unlocking data is successfully verified according to the returned verification result.

In other cases, in order to improve the login efficiency of the relevant applications in the secondary computer module, the embodiment of the present invention may also request the login server for login data reported by the user terminal after scanning the graphic code; and sending the requested login data to the associated application so that the associated application can log in the login server.

The following can be combined with fig. 7 and the main computer module and the sub-computer module to describe the following unlocking of the graphic code:

after the unlocking trigger condition is triggered, the screen locking control application or the plug-in of the secondary computer module responds to the unlocking trigger condition to request the graphic code and the access token from the login server (step S71). Upon receiving the request, the login server returns the graphic code and the access token (step S72). The screen locking control application or the plug-in receives the returned graphic code and the access token and transmits the graphic code to the screen locking application of the main computer module (step S73). And the screen locking application outputs the graphic code to a screen locking interface (step S74), and the user terminal scans the graphic code after starting the scanning function of the user terminal and scans the code to log in (step S75). Specifically, the user login information may be sent to the login server after the graphic code is scanned. Referring to the embodiment of fig. 1F, the unlocking trigger condition may be a predetermined unlocking time, an unlocking notification sent by the lock screen application after the user touches the lock screen interface, or other conditions, which are not limited herein.

After the login server verifies the login data, user authority data is generated based on the user login information (step S76).

The screen locking control application or the plug-in sends an authority data request carrying the access token to the login server, and the login server responds to the authority data request and returns the user authority data (step S77).

After receiving the user permission data, the screen locking control application or the plug-in sends the user permission data to the permission verification server (step S78). The right authentication server returns the authentication result after authenticating the user right data (step S79). And the screen locking control application or the plug-in confirms whether the verification of the unlocking data is successful or not according to the verification result. After the verification is successful, the screen locking control application or the plug-in generates a screen locking closing instruction and sends the screen locking closing instruction to the screen locking application (step S710), and the screen locking application cancels the screen locking interface which is output by the screen locking application and displayed on the top to realize unlocking (step S711). In some cases, the unlocking result may be returned to the screen locking control application or the plug-in after the screen locking application is unlocked.
