Description

Technical Field

[0001] The embodiments of the present invention relate to the field of mobile terminal security technology, and in particular to a method and device for prohibiting restoration of factory settings. Background Art

[0002] Android is widely used in mobile terminals used by government departments, educational institutions, medical institutions and other enterprises and institutions because of its advantages of open source, easy customization and rich application programs. In the use of these Android systems, applications that can be used in the Android system are often customized according to the usage scenarios, and the usage methods are limited. The Android system has an option to restore factory settings in the settings. Misoperation by users or restoration of mobile terminals after loss will result in the loss of original data, making the mobile terminal out of the control environment and no longer applicable to specific scenarios.

[0003] At present, the main way to prohibit factory reset based on the Android system is to hide or disable the factory reset option in the settings of the mobile terminal through the Android system manufacturer before the mobile terminal leaves the factory. The implementation of this method depends on the customization of the system manufacturer, and the modification and compilation of the system takes a long time and the process is cumbersome. In addition, the reusability is poor after actual application, and it cannot be guaranteed that the mobile terminal can be used again after switching scenes. And after a scene is used, the data of the scene cannot be cleared and other operations. Summary of the invention

[0004] In view of this, an object of the embodiments of the present invention is to provide a method and device for prohibiting factory reset, which can flexibly set the prohibition of factory reset.

[0024] When the system version number is not greater than the preset version number, the first function and the second function are called according to the instruction to lift the prohibition of restoring factory settings, so as to enable the host clear receiving component through the first function and enable the external storage formatting component through the second function.

[0025] Furthermore, the method further comprises:

[0026] Capturing the host clear instruction broadcast by the Android system through the host clear receiving component;

[0043] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] See also Figure 1 , shows a flowchart of the steps of the method for prohibiting factory reset according to the first embodiment of the present invention. It can be understood that the flowchart in the embodiment of the method is not used to limit the order of executing the steps. The following is an exemplary description with the computer device 5 as the execution subject. The details are as follows.

[0046] Step S100, when a user-triggered operation of prohibiting factory reset is detected, it is determined whether there is preset system signature information, wherein the system signature information is used to indicate that the permission authorized by the Android system to prohibit factory reset is obtained.

[0047] Exemplarily, when the user triggers the operation of prohibiting factory restoration, it is determined whether there is signature information that is the signature information of the system manufacturer. When it is determined that there is signature information of the system manufacturer, it can be considered that the permission to prohibit factory restoration has been authorized by the Android system, and thus the user has the authority to prohibit factory restoration on the Android system.

[0048] In an exemplary embodiment, the method further comprises:

[0049] A factory reset prohibition switch is set for the factory reset prohibition operation.

[0050] For example, in order to allow users to flexibly control the operation of prohibiting factory restore, a prohibit factory restore switch can be set for the prohibit factory restore operation, and the prohibit factory restore instruction and the release of the prohibit factory restore instruction are triggered according to the state of the prohibit factory restore switch. The prohibit factory restore switch can cooperate with the control instructions at any time to decide whether to execute the prohibit factory restore, thereby maintaining the reusability of the device. Among them, the prohibit factory restore switch can be a physical entity switch or a virtual switch, which can be triggered to open or close the switch through operation instructions such as rotation, touch, click, and slide.

[0051] Step S120: When it is determined that the system has the preset system signature information, a prohibition instruction of restoring to factory settings is triggered.

[0052] Exemplarily, the permission to execute the logic of prohibiting restoring factory settings is obtained through signature information, without making any modification to the system code of the Android system, thereby achieving decoupling from the Android system.

[0053] In an exemplary embodiment, see Figure 2 , the method further includes step S200 and step S220:

[0054] Step S200, monitoring whether the factory reset prohibition switch is in the on state; Step S220, when the factory reset prohibition switch is in the on state, triggering the factory reset prohibition instruction.

[0055] Exemplarily, when the factory reset prohibition switch is in the on state, the factory reset prohibition instruction is triggered to implement the factory reset prohibition operation according to the factory reset prohibition instruction.

[0056] Step S140, prohibiting the operation of the host clear receiving component according to the prohibition of restoring factory settings instruction to achieve the operation of prohibiting restoring factory settings. The host clear receiving component is used to capture the host clear instruction broadcast by the Android system and perform the factory reset operation according to the host clear instruction.

[0057] Exemplarily, the host clear receiving component can be a MasterClearReceiver component, which is used to format the host when it is turned on. Since the logic of the Android system to perform factory reset is that when the Android system detects the triggering of the factory reset instruction, the Android system will send a broadcast android.intent.action.MASTER_CLEAR, that is, a host clear instruction; when the MasterClearReceiver component (full name: com.android.server.MasterClearReceiver) captures the broadcast, it starts to execute the factory reset logic. Therefore, regardless of whether the system version number of the Android system is less than Android 6.0, it is necessary to prohibit the operation of the host clear receiving component. When prohibiting the operation of the host clear receiving component according to the prohibition of factory reset instruction, it is aimed at Android systems with system version numbers greater than Android 6.0, because system versions before API 23 can store applications in external storage, such as SD cards. Therefore, when executing the prohibition of factory reset, different processing is required according to the system version number. For example, when the system version number is not greater than Android 6.0, it is necessary to prohibit the host from clearing the receiving component and the external storage formatting component from running; and when the system version number is greater than Android 6.0, it is only necessary to prohibit the host from clearing the receiving component from running.

[0058] In an exemplary embodiment, see Figure 3 The step S140 further includes:

[0059] Step S141, obtaining the system version number of the Android system according to the instruction prohibiting factory reset; Step S142, determining whether the system version number is greater than a preset version number; Step S143, when the system version number is greater than the preset version number, calling a preset first function according to the instruction prohibiting factory reset, and prohibiting the host from clearing the operation of the receiving component through the first function.

[0060] Exemplarily, the preset version number is pre-set, and its specific version number can be determined according to the naming rules of Android system versions of different manufacturers, for example, the preset version number is Android 6.0, and the corresponding API level is API 23. When the system version number is greater than Android 6.0, the host is prohibited from clearing the operation of the receiving component by calling the first function.

[0061] In an exemplary embodiment, see Figure 4 , after step S142, further comprising:

[0062] Step S144, when the system version number is not greater than the preset version number, calling the preset second function according to the prohibition of factory reset instruction; Step S145, prohibiting the operation of the external storage formatting component through the second function to realize the prohibition of factory reset operation, the external storage formatting component is used to capture the external storage clear instruction broadcast by the Android system, and perform the factory reset operation according to the external storage clear instruction.

[0063] Exemplarily, when the system version number is greater than the preset version number, the factory reset instruction is a host clear instruction; when the system version number is not greater than the preset version number, the factory reset instruction includes a host clear instruction and an external storage clear instruction. Therefore, when the system version number is greater than the preset version number, it is only necessary to prohibit the operation of the host clear receiving component to achieve the operation of prohibiting the factory reset; when the system version number is not greater than the preset version number, it is necessary not only to prohibit the operation of the host clear receiving component, but also to run the external storage formatting component to achieve the operation of prohibiting the factory reset. The external storage formatting component can be an ExternalStorageFormatter component, which is used to format the SD card when it is turned on. When the system version number of the Android system is less than Android 6.0, it is also necessary to call the second function to prohibit the operation of the external storage formatting component, and prevent the SD card from being formatted by prohibiting the external storage formatting component.

[0064] In an exemplary embodiment, see Figure 5 The method further includes steps S300 to S360:

[0065] Step S300, when it is monitored that the switch for prohibiting factory reset is changed from the on state to the off state, triggering the instruction for lifting the prohibition of factory reset, and obtaining the system version number of the Android system according to the instruction for lifting the prohibition of factory reset; Step S320, judging whether the system version number is greater than or equal to the preset version number; Step S340, when it is judged that the system version number is greater than the preset version number, calling the first function according to the instruction for lifting the prohibition of factory reset, so as to enable the host clear receiving component through the first function; Step S360, when the system version number is not greater than the preset version number, calling the first function and the second function according to the instruction for lifting the prohibition of factory reset, so as to enable the host clear receiving component through the first function and enable the external storage formatting component through the second function.

[0066] Exemplarily, when it is necessary to lift the prohibition of restoring factory settings, the prohibition of restoring factory settings switch is changed from the on state to the off state, and the instruction to lift the prohibition of restoring factory settings is triggered based on the off state. Due to the different system version numbers, the components enabled for lifting the prohibition of restoring factory settings are also different. It can be understood that the steps for implementing the operation of prohibiting restoring factory settings are executed in reverse order. First, the first function can be called according to the instruction to lift the prohibition of restoring factory settings to enable the host clear receiving component, and then it can be determined whether the system version number of the Android system is greater than or equal to the preset version number. If it is greater than or equal to the preset version number, the external storage formatting component is enabled. It is also possible to first determine whether the system version number of the Android system is less than the preset version number, and then when the system version number is greater than or equal to the preset version number, enable the host clear receiving component, which simplifies the operation process of prohibiting and lifting the prohibition of restoring factory settings.

[0067] Exemplarily, when the system version number is less than a preset version number, the host clear receiving component and the external storage formatting component are enabled so as to convert the host clear receiving component and the external storage formatting component from a previously disabled state to an enabled state, so that the subsequent host clear receiving component and the external storage formatting component can normally execute data operation instructions, such as executing operation instructions to restore factory settings.

[0068] The first function can disable and enable the host clear receiving component, and perform different operations on the host clear receiving component according to the disable factory reset instruction and the release factory reset instruction. The second function can disable and enable the external storage formatting component, and perform different operations on the external storage formatting component according to the disable factory reset instruction and the release factory reset instruction.

[0069] In an exemplary implementation, the first interface and the second interface may be pre-set, the first function may be called through the first interface, and the second function may be called through the second interface. Before the first interface and the second interface call the first function and the second function, it is necessary to determine whether there is signature information, so that the execution permission for the Android system can be obtained through the signature information, and the component prohibition operation of the Android system is realized, thereby prohibiting the factory reset operation.

[0070] In this embodiment, by implementing the logic code for prohibiting factory reset in the written application according to the scenario, the development workload of the Android system is reduced and the Android development cycle is shortened. In addition, the logic code for prohibiting factory reset can be applied to any device based on the Android system, and can be operated by using an API call function. The set API is based on the Android source code, and the API includes a first interface and a second interface, which has a wide adaptability.

[0071] In an exemplary embodiment, see Figure 6 The method further includes steps S400 to S420:

[0072] Step S400, capturing the host clear instruction broadcast by the Android system through the host clear receiving component; Step S420, when the host clear instruction is captured by the host clear receiving component, executing the preset factory restore logic to implement the factory restore operation.

[0073] Exemplarily, after the prohibition of factory reset is lifted, when the Android system detects that a factory reset instruction is triggered, the Android system will send a broadcast host clear instruction. The host clear instruction can be: android.intent.action.MASTER_CLEAR. The host clear instruction broadcast by the Android system is captured by the host clear receiving component, and then the factory reset operation is executed according to the factory reset logic.

[0074] Embodiment 2

[0075] Please continue reading Figure 7, showing a schematic diagram of program modules of the second embodiment of the device for prohibiting factory restoration of the present invention. In this embodiment, the device 50 for prohibiting factory restoration may include or be divided into one or more program modules, one or more program modules are stored in a storage medium, and are executed by one or more processors to complete the present invention, and can implement the above-mentioned method for prohibiting factory restoration. The program module referred to in the embodiment of the present invention refers to a series of computer program instruction segments that can perform specific functions, and is more suitable for describing the execution process of the device 50 for prohibiting factory restoration in a storage medium than the program itself. The following description will specifically introduce the functions of each program module of this embodiment:

[0076] The judgment module 500 is used to judge whether there is preset system signature information when a user-triggered prohibition of restoring factory settings operation is monitored. The system signature information is used to represent the permission authorized by the Android system to allow the prohibition of restoring factory settings to be executed.

[0077] Exemplarily, when the user triggers the operation of prohibiting factory reset, it is determined whether there is signature information that is the signature information of the system manufacturer. When it is determined that there is signature information of the system manufacturer, the user has the authority to prohibit factory reset on the Android system.

[0078] In an exemplary embodiment, the system is also used to perform the following method:

[0079] A factory reset prohibition switch is set for the factory reset prohibition operation.

[0080] For example, in order to allow users to flexibly control the operation of prohibiting factory reset, a factory reset switch can be set for the factory reset operation, and the factory reset instruction and the factory reset instruction can be triggered according to the state of the factory reset switch. The factory reset switch can decide whether to execute the factory reset at any time in accordance with the control instruction, thereby maintaining the reusability of the device.

[0081] The trigger module 502 is used to trigger the prohibition of restoring to factory settings instruction when it is determined that there is preset system signature information.

[0082] Exemplarily, the permission to execute the logic of prohibiting restoring factory settings is obtained through signature information, without making any modification to the system code of the Android system, thereby achieving decoupling from the Android system.

[0083] In an exemplary embodiment, the system is also used to perform the following method:

[0084] Monitor whether the factory reset prohibition switch is in an on state; when the factory reset prohibition switch is in the on state, trigger the factory reset prohibition instruction.

[0085] Exemplarily, when the factory reset prohibition switch is in the on state, the factory reset prohibition instruction is triggered to implement the factory reset prohibition operation according to the factory reset prohibition instruction.

[0086] The prohibition module 504 is used to prohibit the operation of the host clear receiving component according to the prohibition of restoring factory settings instruction to realize the operation of prohibiting restoring factory settings. The host clear receiving component is used to capture the host clear instruction broadcast by the Android system and perform the factory reset operation according to the host clear instruction.

[0087] Exemplarily, the host clear receiving component can be a MasterClearReceiver component. Since the logic of the Android system to perform factory reset is that when the Android system detects the triggering of the factory reset instruction, the Android system will send a broadcast android.intent.action.MASTER_CLEAR. When the MasterClearReceiver component (com.android.server.MasterClearReceiver) captures the broadcast, it starts to execute the factory reset logic. Therefore, regardless of whether the system version number of the Android system is less than Android 6.0, it is necessary to prohibit the operation of the host clear receiving component. When prohibiting the operation of the host clear receiving component according to the prohibition of factory reset instruction, it is aimed at Android systems with system versions greater than Android 6.0, because system versions before API 23 can store applications in external storage, such as SD cards. Therefore, when executing the prohibition of factory reset operation, different processing needs to be performed according to the system version number. For example: when the system version number is not greater than Android6.0, it is necessary to prohibit the operation of the host clear receiving component and the external storage formatting component; and when the system version number is greater than Android6.0, it is only necessary to prohibit the operation of the host clear receiving component.

[0088] In an exemplary embodiment, the prohibition module 504 is further configured to:

[0089] According to the instruction prohibiting factory reset, the system version number of the Android system is obtained; it is determined whether the system version number is greater than the preset version number; when the system version number is greater than the preset version number, a preset first function is called according to the instruction prohibiting factory reset, and the host is prohibited from clearing the operation of the receiving component through the first function.

[0090] Exemplarily, the preset version number is pre-set, and its specific version number can be determined according to the naming rules of Android system versions of different manufacturers, for example, the preset version number is Android 6.0, and the corresponding API level is API 23. When the system version number is greater than Android 6.0, the host is prohibited from clearing the operation of the receiving component by calling the first function.

[0091] In an exemplary embodiment, the prohibition module 504 is further configured to:

[0092] When the system version number is not greater than the preset version number, the preset second function is called according to the prohibition of factory reset instruction; the operation of the external storage formatting component is prohibited by the second function to realize the prohibition of factory reset operation, and the external storage formatting component is used to capture the external storage clearing instruction broadcast by the Android system, and perform the factory reset operation according to the external storage clearing instruction.

[0093] Exemplarily, when the system version number is greater than the preset version number, the factory reset instruction is a host clear instruction; when the system version number is not greater than the preset version number, the factory reset instruction includes a host clear instruction and an external storage clear instruction. Therefore, when the system version number is greater than the preset version number, it is only necessary to prohibit the operation of the host clear receiving component to achieve the operation of prohibiting the factory reset; when the system version number is not greater than the preset version number, it is necessary not only to prohibit the operation of the host clear receiving component, but also to run the external storage formatting component to achieve the operation of prohibiting the factory reset. The external storage formatting component can be an ExternalStorageFormatter component. When the system version number of the Android system is less than Android 6.0, it is also necessary to call the second function to prohibit the operation of the external storage formatting component, and prevent the SD card from being formatted by prohibiting the external storage formatting component.

[0094] In an exemplary implementation, the first interface and the second interface may be pre-set, the first function may be called through the first interface, and the second function may be called through the second interface. Before the first interface and the second interface call the first function and the second function, it is necessary to determine whether there is signature information, so that the execution permission for the Android system can be obtained through the signature information, and the component prohibition operation of the Android system is realized, thereby prohibiting the operation of restoring the factory settings.

[0095] In this embodiment, the logic code for prohibiting factory reset is implemented in the written application according to the scenario, which reduces the development workload of the Android system and shortens the Android development cycle. In addition, the logic code for prohibiting factory reset can be applied to any device based on the Android system, and can be operated by using API call functions, and the set APIs are all based on Android source code, which has wide adaptability.

[0096] In an exemplary embodiment, the system is also used to perform the following method:

[0097] When it is monitored that the switch for prohibiting factory reset is changed from the on state to the off state, a command for lifting the prohibition of factory reset is triggered, and the system version number of the Android system is obtained according to the command for lifting the prohibition of factory reset; it is determined whether the system version number is greater than the preset version number; when it is determined that the system version number is greater than the preset version number, the first function is called according to the command for lifting the prohibition of factory reset, so as to enable the host clear receiving component through the first function; when the system version number is not greater than the preset version number, the first function and the second function are called according to the command for lifting the prohibition of factory reset, so as to enable the host clear receiving component through the first function and enable the external storage formatting component through the second function.

[0098] Exemplarily, when it is necessary to lift the prohibition of restoring factory settings, the prohibition of restoring factory settings switch is changed from the on state to the off state, and the instruction to lift the prohibition of restoring factory settings is triggered based on the off state. Due to the different system version numbers, the components enabled for lifting the prohibition of restoring factory settings are also different. It can be understood that the steps for implementing the operation of prohibiting restoring factory settings are executed in reverse order. First, the host clear receiving component can be enabled according to the instruction to lift the prohibition of restoring factory settings, and then it can be determined whether the system version number of the Android system is greater than the preset version number. If it is greater than the preset version number, the external storage formatting component is enabled. It is also possible to first determine whether the system version number of the Android system is not greater than the preset version number, and then when the system version number is greater than or equal to the preset version number, enable the host clear receiving component, which simplifies the operation process of prohibiting and lifting the prohibition of restoring factory settings.

[0099] Exemplarily, when the system version number is not greater than a preset version number, the host clear receiving component and the external storage formatting component are enabled so as to convert the host clear receiving component and the external storage formatting component from a previously disabled state to an enabled state, so that the subsequent host clear receiving component and the external storage formatting component can normally execute data operation instructions, such as executing operation instructions to restore factory settings.

[0100] The first function can disable and enable the host clear receiving component, and perform different operations on the host clear receiving component according to the disable factory reset instruction and the release factory reset instruction. The second function can disable and enable the external storage formatting component, and perform different operations on the external storage formatting component according to the disable factory reset instruction and the release factory reset instruction.

[0101] In an exemplary embodiment, the system is also used to perform the following method:

[0102] The host clearing receiving component captures the host clearing instruction broadcasted by the Android system; when the host clearing receiving component captures the host clearing instruction, the preset factory restoration logic is executed to implement the factory restoration operation.

[0103] Exemplarily, after the prohibition of factory reset is lifted, when the Android system detects that a factory reset instruction is triggered, the Android system will send a broadcast host clear instruction. The host clear instruction can be: android.intent.action.MASTER_CLEAR. The host clear instruction broadcast by the Android system is captured by the host clear receiving component, and then the factory reset operation is executed according to the factory reset logic.
