Description

A terminal access control method

This application is a divisional application. The application number of the original application is 201880095183.6, and the original application date is July 13, 2018. The entire content of the original application is incorporated in this application by reference.

technical field

The present invention relates to the field of communication technology, in particular to a terminal access authority control method.

Background technique

With the increase of household terminal devices, such as smart TVs, set-top boxes, PADs, mobile phones, etc., people use more and more terminals in their daily life and study. Various terminals are becoming more and more attractive to minors, and the unrestrained and unrestricted use of terminals will also have a negative impact on minors.

In order to prevent minors from watching TV, set-top boxes, mobile phones, PADs and other terminal equipment unrestrainedly, many terminal equipment manufacturers usually produce terminals with a child lock function. After the child lock is turned on, the terminal equipment will not respond to operations, or only Provides limited access.

There are two main methods of locking and unlocking the existing child lock, namely: 1. Trigger the child lock through a specific key combination, and need to manually operate again when releasing it; 2. Install management software on the terminal and unlock it by entering a password.

However, no matter which child lock method is adopted, the user needs to manually input the unlocking operation. For example: after the terminal is locked, when the user needs to use the locked function, he first needs to enter a password to perform an unlocking operation to unlock the locked function. For example, for a smart TV or a set-top box, the locked channel or signal source needs to be unlocked through the remote control, and then the program of the channel or signal source can be watched normally. Only when the password input operation is performed on the currently unlocked channel or signal source on the interface can the current channel or signal source be re-locked, so as to prevent children from watching the program of the channel or signal source. It can be seen that no matter whether the user locks or unlocks the terminal function, he needs to use the remote control or the human-computer interaction interface to input a password once, which is cumbersome and inconvenient to use.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, but not all of them. It should be noted that, based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The main purpose of the embodiment of the present invention is to manage the use authority of the terminal, so as to prevent the terminal from being used without supervision when the relevant supervision personnel of the terminal are not present. It can be applied to various application scenarios that require the management of terminal use rights, such as preventing minors from using smart TVs, set-top boxes, and PADs without parental supervision; avoiding information leakage after terminal loss ; Prevent personal terminals from being used by strangers in the absence of the owner, etc. In the embodiment of the present invention, judging whether the terminal device is near the target device is used as a basis for judging whether the terminal device is within the control range of supervisors, so as to determine whether to implement or release access restriction. The selected target devices are usually portable devices of terminal supervisors, such as handheld terminals, smart bracelets, or other wearable devices.

The disclosed embodiments of the present invention relate to a terminal access authority control method, wherein the terminals can be of various types, such as smart TVs, set-top boxes, PADs, mobile phones, computers, smart home appliances and other smart terminals. Access rights can involve different content for different types of terminals. For example, for smart TVs or set-top boxes, the control of access rights can mean that you cannot watch certain channels or signal sources, or you cannot operate the TV, that is, you cannot watch any channels. ; For terminals such as PADs, mobile phones, and computers, the control of access rights can refer to the inability to use certain functions or applications, such as the playback of audio and video files, the opening of game applications, etc., or the inability to operate such terminals, that is, the terminal There is no response to the input operation instructions; for smart home appliances, some or all of its functions may also be restricted.

FIG. 1 is a flow chart of a method for controlling terminal access rights according to an embodiment of the present invention.

S101: Determine whether a terminal access authority control function is enabled in a first state.

When the access authority control function is set in the terminal, it is determined in the first state whether the access authority control function is enabled. The terminal can recognize or perceive the first state. For example, the terminal can identify its own state through a processor or other modules, for example, application execution state, action execution state, screen lock state and unlock trigger state, restart or power-on trigger state, and the like. The terminal can display its status through the display.

When the terminal recognizes the first state, it is determined whether the access authority control function of the terminal is in the enabled state. The access right control function is to restrict some or all functions in the terminal when certain conditions are met. The functions that can be restricted include the operation and/or use of some or all applications, the reading and/or writing of some or all terminal data, the receiving and/or playing of some or all media resources or channels, and the like.

The state of the access right control function may be manually set by the user in advance. The status of the access right control function can be enabled or disabled. The terminal can enable or disable the access control function by detecting user input. For example, the terminal may display a menu icon on the touch screen for enabling or disabling the access authority control function. The terminal may turn on or off the access right control function by detecting a touch input to a menu icon for turning on the access right control function or a menu icon for turning off the access right control function. If the terminal is a smart TV or a set-top box, the terminal may enable or disable the access authority control function by detecting a remote control selection of a menu icon for enabling the access authority control function or a menu icon for disabling the access authority control function. Figure 4 is a setting interface of an exemplary access authority control function according to an embodiment of the present invention. As shown in Figure 4, the user can choose to set whether to enable the above access authority control function according to needs, save the setting results, and choose to enable the access authority After the control function, the interface can be transferred to the access control function to set, select or manually input the target device, and then save it. If the device information and authority information have been set, after the access authority control function is enabled, the terminal performs access authority control according to the previous setting information. For terminals that need to be shut down after use, such as smart TVs or set-top boxes, if the access control function is enabled, the access control function will be enabled without resetting after each boot.

If it is determined in the first state that the terminal access authority control function is off, go to step S106.

S106: Do not limit the terminal access authority, that is, respond to the corresponding operation of the terminal according to the normal state, for example, the first state is the power-on trigger state, then enter the power-on state when it is determined that the terminal access authority control function is off, and do not perform authority restrictions on subsequent operations ; If the first state is the unlock trigger state, enter the screen unlock state when it is determined that the terminal access control function is off, and do not perform permission restrictions for subsequent operations; if the first state is to use various functions of the terminal or read terminal data, Then when it is determined that the terminal access authority control function is off, various functions of the terminal can be used or data related to the terminal can be read without restriction.

If it is determined in the first state that the terminal access authority control function is enabled, go to step S102.

S102: Obtain terminal peripheral device information;

The peripheral device information of the terminal, that is, the information of other devices that are closer to the terminal in the environment where the terminal is located. In the embodiment of the present invention, whether a short-distance wireless communication connection can be established with the terminal, or whether it is found by the terminal through short-distance wireless communication technology can be used as an indicator to determine whether the device is relatively close to the terminal. Short-range wireless communication technologies include: wi-fi, Mesh, Bluetooth, ZigBee, Hlilink, Thread, NFC, UWB, etc.

There are multiple methods for a terminal to obtain information about its surrounding devices. It includes that a terminal can access a local area network through a local area network device, such as a wi-fi network, to obtain information about other devices in the local area network where it is located. For example, at home, terminals such as smart TVs, set-top boxes, and PADs can be connected to a home router in a wired or wireless manner to access a home local area network. Or it can search for the personal area network existing around it, such as searching for the nearby personal area network and its corresponding devices through a connection such as bluetooth or wi-fi.

There are many ways to obtain device information in the LAN. For example, in the LAN, all other device information in the same LAN can be obtained through the NetBios protocol. The specific protocol flow is shown in Figure 2. Terminal 201 sends NBNS to the LAN device. Name query request, the LAN device 200 broadcasts the NBNS Name query request to other devices 202 and 203 in the LAN after receiving the request, and the other devices 202 and 203 return the NBNS Name registration message to send the device information to the terminal 201 through the LAN device 200 , so that the terminal can obtain other device information in the LAN.

S103: Determine whether there is a target device according to the acquired device information.

The target device is usually set as the portable device of the terminal supervisor. Based on whether the target device and the terminal are in the same local area network, or whether the target device and the terminal can conduct short-distance wireless connections, it is judged whether the terminal is within the supervision range of the terminal supervisor. Therefore, it is necessary to judge whether the target device is based on the obtained device information. It exists in the obtained device information. In addition to obtaining the information of devices near the terminal, the above judgment also needs to obtain the information of the target device, that is, the information of the portable device of the terminal supervisor.

The target device information may be preset by the user through the menu selection interface of the terminal. For example, the terminal may display a menu interface for selecting or inputting target device information on the touch screen. The terminal may set the target device information by detecting a touch input or key input to a menu interface for selecting or inputting the target device information. If the terminal is a smart TV or a set-top box, the terminal may set the target device information by detecting a remote control selection or manual input to a menu interface for selecting or inputting the target device information.

FIG. 3 is an exemplary setting interface for access control information of a terminal in an embodiment of the present invention. In the embodiment of the present invention, setting the control information of a terminal mainly includes the setting of two types of information, which are device information and permission information. The embodiment of the present invention can be mainly applied to judging whether the supervisor of the terminal is within the supervisory scope of the terminal, so the setting of device information can be selected through network scanning or manually input the personal device (target device) information of the supervisor, the target device information One or more can be set as required, and the setting form can be a single information selection or manual input form, and can also be set in the form of a list of device information to set the list of devices that can control the access rights of the terminal.

In addition, as shown in FIG. 3 , you can also choose the type of permission control, for example, you can choose to only watch a specific channel, or only use a specific application, or prohibit the use. Figure 3 is only an example for the setting of authority information. The access authority control of the terminal can also be in the default state, which does not need to be selected. For example, after the authority control can be enabled by default, the terminal is in a prohibited state, and the use of all functions is restricted; or It may also be that different parent devices correspond to different permission restriction types.

Judging whether the target device exists in the peripheral device information according to the acquired peripheral device information of the terminal. Specifically, it may be to find out whether there is a target device in the obtained peripheral device information. There are many ways to search, for example, according to the target device The setting sequence of the obtained peripheral device information is searched sequentially to see if there is a target device in the obtained peripheral device information. Once the target device is found, the search action will be stopped. The existence of the target device in the surrounding device information.

If there is a target device in the acquired peripheral device information, go to step S104.

S104: Release the restriction on the access authority of the terminal.

When the judgment result is that there is a target device in the acquired peripheral device information, it is considered that the terminal is within the supervisor's control range, and the access restriction on the terminal is released.

If there is no target device in the acquired peripheral device information, go to step S105.

S105: Perform corresponding access restriction on the terminal.

If the judgment result is that there is no target device in the acquired peripheral device information, it is considered that the terminal is not within the control range of the terminal supervisor, and the access authority restriction on the terminal is enabled.

The above rights management method, by obtaining the terminal peripheral device information, and whether the target device is in the vicinity of the terminal as a sign of whether the terminal is within the supervision of the control personnel, to determine whether to restrict or remove the access restriction on the terminal. The embodiment of the present invention is convenient and effective for terminal access authority management, and does not need to be manually set repeatedly. Once the target device and the controlled terminal are connected to the same local area network, the access authority restriction will be lifted. Once the target device leaves the local area network, the terminal will be accessed in time. The authority control avoids the problem in the prior art that you need to manually enter the memorized password to remove the authority restriction, or forget the password and cannot remove the authority restriction, or need to manually set the authority restriction again every time you leave.

The above rights management method is only a specific example of the present invention. The acquisition of peripheral device information of the terminal and the judgment of the target device can be carried out under any conditions and environments, and are not limited to determining the terminal access status in the first state. Whether the authority control function is enabled; if the access authority control function is enabled, the peripheral device information of the terminal is obtained and the target device is judged.

FIG. 8 is a flow chart of another method for controlling terminal access rights according to an embodiment of the present invention. For smart TVs or set-top boxes, in order to prevent unrestricted viewing of TV programs by minors, there are usually certain restrictions on the use of TV by minors, such as restricting viewing of specific programs or signal sources, or even Does not respond to any action. Therefore, it will be necessary to determine whether the terminal is configured with an access authority control function when a power-on action is detected. Fig. 8 is a flow chart of a method for executing the access authority control function of such a terminal.

S800: Determine whether a power-on trigger is detected.

The power-on trigger may be the input of a predetermined key, and the predetermined key may be a power key, a power-on key, or turning on a power supply. After detecting the power-on trigger, the terminal can turn on the screen display and enter the power-on state.

If a power-on trigger is detected, enter step S801, and if no power-on trigger is detected, no subsequent operations will be triggered.

S801: Determine whether the access control function is enabled.

After detecting the power-on trigger, the terminal determines whether the access control function of the terminal is enabled. The access right control function is to restrict some or all functions in the terminal when certain conditions are met. The functions that can be restricted include the operation and/or use of some or all applications, the reading and/or writing of some or all terminal data, the receiving and/or playing of some or all media resources or channels, and the like.

The state of the access right control function may be manually set by the user in advance. The status of the access right control function can be enabled or disabled. The terminal can enable or disable the access control function by detecting user input. For example, the terminal may turn on or off the access right control function by detecting a remote control selection of a menu icon for turning on the access right control function or a menu icon for turning off the access right control function. Figure 4 is a setting interface of an exemplary access authority control function according to an embodiment of the present invention. As shown in Figure 4, the user can choose to set whether to enable the above access authority control function according to needs, save the setting results, and choose to enable the access authority After the control function, the interface can be transferred to the access control function to set, select or manually enter the target device by pressing the key, and then save it. If the device information and authority information have been set, after the access authority control function is enabled, the terminal will perform access authority control according to the previous setting information, and the access authority control function will be turned on without resetting after each shutdown and startup.

If it is determined in the first state that the terminal access authority control function is disabled, go to step S806.

S806: Do not restrict terminal access rights; that is, respond to the corresponding operation of the terminal in a normal state, that is, after the power-on trigger, enter the power-on state when it is determined that the terminal access rights control function is off, and do not restrict the rights of subsequent operations.

If it is determined that the terminal access authority control function is enabled, go to step S802.

S802: Obtain device information in the local area network where the terminal is located.

There are multiple ways for a terminal to obtain device information in its local area network. These include that the terminal can access the local area network through a local area network device, such as a wireless router; or search the personal area network of other surrounding devices to obtain information about other devices in the local area network where it is located. For example, at home, terminals such as smart TVs and set-top boxes can be connected to a home router in a wired or wireless manner to access the home local area network, and obtain other access device information by scanning the home local area network. Or you can search the personal area network established by other devices in the surrounding area to obtain the device information in the local area network where the terminal is located. There can be one or more LANs where the terminal is located.

S803: Determine whether the target terminal device is in the local area network where the terminal is located according to the acquired information about the local area network device.

The target device is usually set as the portable device of the terminal supervisor. Based on whether the target device is in the same local area network as the terminal, it is judged whether the terminal is within the supervisory scope of the terminal supervisor. Therefore, it is necessary to judge whether the target device exists in the obtained device information according to the obtained device information. In addition to obtaining the information of devices near the terminal, the above judgment also needs to obtain the information of the target device, that is, the information of the portable device of the terminal supervisor.

The target device information may be preset by the user through the menu selection interface of the terminal. The terminal may set the target device information by detecting a remote control selection or a manual key input to a menu interface for selecting or inputting the target device information.

Fig. 3 is an exemplary setting interface for terminal access authority control in the embodiment of the present invention. In the embodiment of the present invention, setting the authority control information for the terminal mainly includes the setting of two types of information, namely device information and authority information. The embodiment of the present invention can be mainly applied to judging whether the supervisor of the terminal is within the supervisory scope of the terminal, so the setting of device information can be selected through network scanning or manually input the personal device (target device) information of the supervisor, the target device information One or more can be set as required, and the setting form can be a single information selection or manual input form, and can also be set in the form of a list of device information to set the list of devices that can control the access rights of the terminal.

In addition, as shown in FIG. 3 , you can also choose the type of permission control, for example, you can choose to only watch a specific channel, or only use a specific application, or prohibit the use. Figure 3 is only an example for the setting of authority information. The access authority control of the terminal can also be in the default state, which does not need to be selected. For example, after the authority control can be enabled by default, the terminal is in a prohibited state, and the use of all functions is restricted; or It may also be that different parent devices correspond to different permission restriction types.

According to the obtained LAN device information to determine whether the target device exists in the obtained LAN device information, specifically, it can be to find out whether there is a target device in the obtained LAN device information. There are many ways to search, such as according to The setting sequence of the target device, sequentially search whether there is a target device in the obtained LAN device information, and stop the search action once the target device is found, or search in parallel whether there is a target device in the obtained LAN device information, and obtain all Existence of the target device in the acquired LAN device information.

If there is a target device in the acquired LAN device information, go to step S804.

S804: Release the restriction on the access authority of the terminal.

When the judgment result is that there is a target device in the acquired LAN device information, it is considered that the terminal is within the supervisor's control range, and the access restriction on the terminal is lifted.

If there is no target device in the acquired LAN device information, go to step S805.

S805: Restrict the access authority of the terminal.

If the judgment result is that there is no target device in the obtained LAN device information, it is considered that the terminal is not within the control range of the terminal supervisor, and the access restriction on the terminal is enabled.

In the above rights management method, whether the target device is in the vicinity of the terminal is used as a sign of whether the terminal is within the supervision scope of the controller, so as to determine whether to restrict or remove the access restriction on the terminal. The embodiment of the present invention is convenient and effective for terminal access authority management, without repeated manual setting, the terminal searches the network when it is turned on, and once the target device and the terminal to be controlled are in the same local area network, the access authority restriction is lifted, avoiding the need for prior art There is a problem that you need to remember the password to manually enter the permission restriction, or forget the password and cannot remove the permission restriction.

FIG. 9 is a flow chart of another method for controlling terminal access rights according to an embodiment of the present invention.

S901: Trigger acquisition of terminal peripheral device information when a specific condition is met.

The specific condition may be a specified action, that is, the terminal is triggered to acquire peripheral device information every time a specified action is detected, or a set trigger period, that is, the peripheral device information is acquired every specific time.

S902: Obtain information about peripheral devices of the terminal.

The peripheral device information of the terminal, that is, the information of other devices that are closer to the terminal in the environment where the terminal is located. In the embodiment of the present invention, whether a short-distance wireless communication connection can be established with the terminal, or whether it is found by the terminal through short-distance wireless communication technology can be used as an indicator to determine whether the device is relatively close to the terminal. Short-range wireless communication technologies include: wi-fi, Mesh, Bluetooth, ZigBee, Hlilink, Thread, NFC, UWB, etc.

There are multiple methods for a terminal to obtain information about its surrounding devices. It includes that the terminal can access the local area network through the local area network device to obtain the information of other devices in the local area network where it is located. For example, at home, a terminal may be connected to a home router in a wired or wireless manner to access a home local area network. Or you can set up a personal area network by yourself, or search the personal area network of other devices.

S903: Determine whether there is a target terminal device according to the acquired peripheral device information.

The target device is usually set as the portable device of the terminal supervisor. Based on whether the target device and the terminal are in the same local area network, or whether the target device and the terminal can conduct short-distance wireless connections, it is judged whether the terminal is within the supervision range of the terminal supervisor. Therefore, it is necessary to judge whether the target device is based on the obtained device information. It exists in the obtained device information. In addition to obtaining the information of devices near the terminal, the above judgment also needs to obtain the information of the target device, that is, the information of the portable device of the terminal supervisor.

The target device information may be preset by the user through the menu selection interface of the terminal. For example, the terminal may display a menu interface for selecting or inputting target device information on the touch screen. The terminal may set the target device information by detecting a touch input or key input to a menu interface for selecting or inputting the target device information. If the terminal is a smart TV or a set-top box, the terminal may set the target device information by detecting a remote control selection or manual input to a menu interface for selecting or inputting the target device information.

Fig. 3 is an exemplary setting interface for terminal access authority control in the embodiment of the present invention. In the embodiment of the present invention, setting the authority control information for the terminal mainly includes the setting of two types of information, namely device information and authority information. The embodiment of the present invention can be mainly applied to judging whether the supervisor of the terminal is within the supervisory scope of the terminal, so the setting of device information can be selected through network scanning or manually input the personal device (target device) information of the supervisor, the target device information One or more can be set as required, and the setting form can be a single information selection or manual input form, and can also be set in the form of a list of device information to set the list of devices that can control the access rights of the terminal.

In addition, as shown in FIG. 3 , you can also choose the type of permission control, for example, you can choose to only watch a specific channel, or only use a specific application, or prohibit the use. Figure 3 is only an example for the setting of authority information. The access authority control of the terminal can also be in the default state, which does not need to be selected. For example, after the authority control can be enabled by default, the terminal is in a prohibited state, and the use of all functions is restricted; or It may also be that different parent devices correspond to different permission restriction types.

Judging whether the target device exists in the peripheral device information according to the acquired peripheral device information of the terminal. Specifically, it may be to find out whether there is a target device in the obtained peripheral device information. There are many ways to search, for example, according to the target device The setting sequence of the obtained peripheral device information is searched sequentially to see if there is a target device in the obtained peripheral device information. Once the target device is found, the search action will be stopped. The existence of the target device in the surrounding device information.

If there is a target device in the acquired peripheral device information, go to step S904.

S904: Release the restriction on the access authority of the terminal.

When the judgment result is that there is a target device in the acquired peripheral device information, it is considered that the terminal is within the supervisor's control range, and the access restriction on the terminal is released.

If there is no target device in the acquired peripheral device information, go to step S905.

S905: Restrict the access authority of the terminal.

If the judgment result is that there is no target device in the acquired peripheral device information, it is considered that the terminal is not within the control range of the terminal supervisor, and the access authority restriction on the terminal is enabled.

In the above rights management method, whether the target device is around the terminal is used as a sign of whether the terminal is within the supervision scope of the controller, so as to determine whether to restrict or remove the access restriction on the terminal. The embodiment of the present invention is convenient and effective for terminal access authority management, and does not need to be manually set repeatedly. Once the target device and the controlled terminal are connected to the same local area network, the access authority restriction will be lifted. Once the target device leaves the local area network, the terminal will be accessed in time. The authority control avoids the problem in the prior art that you need to manually enter the memorized password to remove the authority restriction, or forget the password and cannot remove the authority restriction, or need to manually set the authority restriction again every time you leave.

The terminal 501 can obtain the information of other access devices in the LAN through the LAN device 500, and can pass a short message The distance wireless communication technology searches for connectable devices to obtain peripheral device information. The peripheral device information can be obtained by searching the surrounding personal area network, or combined with one or more acquisition methods at the same time to comprehensively obtain peripheral device information. After the terminal 501 acquires the peripheral device information (device A, device B, and device C), it judges whether the target device is included in the acquired device information. Compare, or search in order whether there is target device information in the obtained device information. As shown in Figure 5, if after comparison, it is found that device C exists in the access control device information (target device C) saved by the terminal, it is considered that the supervisor of target device C is also around the terminal, that is, the terminal is in the supervisor If the target device does not exist in the obtained device information, it is considered that the terminal is not within the control range of the supervisor, and then according to the access control function The settings limit all or part of the operations on the terminal.
