[0061] To facilitate the understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will be described first below.

[0062] The secure sandbox technology is a security mechanism that can provide an isolated environment for the client. The virtual environment constructed using the secure sandbox technology is called a sandbox, which can also be referred to as a sand box. The data of the client of the mobile terminal device is stored in the sandbox of the client to prevent other systems or other clients from accessing it. The operating system of the mobile terminal device cannot directly access the data in the sandbox of the client, resulting in difficulty for the operating system to clean the data in the sandbox of the client, and the data cleaning efficiency is relatively low. In a possible scenario, it is necessary for the user to manually trigger the data cleaning function provided by the client to clean the data in the sandbox. The efficiency of the user manually triggering the data cleaning is relatively low, which easily leads to the backlog of the data to be cleaned and occupies storage resources.

[0063] Based on this, the embodiments of the present application provide a data cleaning method. In this method, the operating system obtains a first cleaning instruction for the data in the sandbox of the target client, and sends a second cleaning instruction to the target client through the inter-process communication interface connected to the target client. In response to obtaining the second cleaning instruction sent by the operating system from the inter-process communication interface, the target client cleans the data in the sandbox. In this way, the communication between the operating system and the target client can be realized by using the inter-process communication interface, and the operating system triggers the cleaning of the data in the sandbox of the client, thereby improving the efficiency of cleaning the data in the sandbox of the client.

[0064] The following will be described with reference to the scenario example shown in the accompanying drawings. Those skilled in the art can understand that Figure 1 The shown framework schematic diagram is only an example in which the embodiments of the present application can be implemented. The scope of application of the embodiments of the present application is not limited by any aspect of this framework.

[0065] In a possible implementation, refer to Figure 1 as shown Figure 1It is a schematic framework diagram of an exemplary application scenario provided by an embodiment of the present application. The data cleaning method provided by the embodiment of the present application can be applied to a mobile terminal device. The mobile terminal device is, for example, a mobile phone, a tablet computer, or other devices. The operating system 100 of the mobile terminal device communicates with the client 101 of the mobile device through an IPC (Inter-Process Communication) interface. As an example, the operating system 100 includes a cleaning management module 1001. The client 101 includes a cleaning management module 1011. The cleaning management module 1001 communicates with the cleaning management module 1011 through the IPC interface. The cleaning management module 1001 included in the operating system 100 is used to manage the cleaning tasks of the operating system 100. The cleaning tasks of the operating system 100 can be triggered and created by the user, or automatically created based on the running requirements of the operating system 100. The created cleaning tasks can be triggered and executed in real time, or triggered and executed at a scheduled time. The cleaning management module 1001 obtains a first cleaning instruction for the data in the sandbox of the client 101, and sends a second cleaning instruction to the cleaning management module 1011 through the inter-process communication interface connected to the cleaning management module 1011 of the client 101. The second cleaning instruction is used to instruct the client 101 to clean the data in the sandbox of the client 101. The cleaning management module 1011 of the client 101 responds to obtaining the second cleaning instruction and cleans the data in the sandbox of the client 101. In this way, it can be realized that the operating system triggers the cleaning of the data in the sandbox of the client, improving the data cleaning efficiency.

[0066] To facilitate understanding of a data cleaning method provided by an embodiment of the present application, a data cleaning method provided by an embodiment of the present application will be described below with reference to the accompanying drawings.

[0067] See Figure 2 As shown, this figure is a schematic flowchart of a data cleaning method provided by an embodiment of the present application. As Figure 2 shown, the method may include S201 - S203:

[0068] S201: The operating system obtains a first cleaning instruction for the data in the sandbox of the target client.

[0069] The target client and the operating system belong to the same device. The target client is a client installed on this device. The target client can be a pre-configured client that can perform data cleaning in the sandbox. As an example, the information of the client that can clean the data in the sandbox is pre-configured. Based on the information of the client that can clean the data in the sandbox configured, the operating system can determine the client that can clean the data in the sandbox.

[0070] The operating system obtains a first cleaning instruction for the data within the sandbox of the target client. The embodiments of this application do not limit the triggering manner of the first cleaning instruction. In a possible implementation, the first cleaning instruction is generated by the user's trigger or automatically triggered by the operating system. The user and the operating system can configure the time to execute the first cleaning instruction. For example, configure to execute the first cleaning instruction immediately or configure to execute it at a scheduled time. In another possible implementation, the first cleaning instruction can be triggered when a cleaning task is executed. The cleaning task can be set by the user or automatically generated by the operating system. The cleaning task can be executed in real time, that is, after obtaining the cleaning task information, the cleaning task information is immediately executed to generate the first cleaning task. The cleaning task can also be executed at a scheduled time. The scheduled execution time can be set in advance. For example, for a cleaning task set by the user, the user can set the time to execute the cleaning task. The cleaning task can also be executed periodically. For example, for a cleaning task set by the user, the user can set the cycle duration for periodic execution of the cleaning task.

[0071] The first cleaning instruction is for the data within the sandbox of the target client. The target client targeted by the first cleaning instruction can be determined according to the user or the operating system's running requirements. For example, the target client targeted by the first cleaning instruction can be a client selected by the user. The first cleaning instruction includes the client information of the target client. For another example, the target client targeted by the first cleaning instruction can be all the clients that can clean the data within the sandbox. In this way, flexible selection of the target client can be achieved, and the cleaning requirements can be met.

[0072] S202: The operating system sends a second cleaning instruction to the target client through the inter-process communication interface connected to the target client.

[0073] The operating system and the target client communicate through the IPC interface. The IPC interface between the operating system and the target client can be established in advance.

[0074] The operating system sends a second cleaning instruction to the target client through the IPC interface connected to the target client. The second cleaning instruction is used to instruct the target client to clean the data within the sandbox of the target client. The operating system can use the second cleaning instruction to trigger the target client to clean the data within the sandbox. The data format of the second cleaning instruction can be a predefined data format for the target client to process the second cleaning instruction.

[0075] S203: In response to obtaining the second cleaning instruction sent by the operating system of the device from the inter-process communication interface, the target client cleans the data within the sandbox.

[0076] After the target client obtains the second cleaning instruction through the IPC interface, it cleans the data in the sandbox. The cleaning of the data in the sandbox by the target client can be implemented by the cleaning function configured by the target client. In some possible implementation manners, the target client obtains information about the data in the sandbox, determines the data that can be cleaned based on the information about the data in the sandbox, and cleans the data that can be cleaned.

[0077] Based on the relevant content of S201 - S203 above, it can be seen that the operating system can trigger the target client to clean the data in the sandbox, without manually triggering the client to clean the data in the sandbox, improving the cleaning efficiency of the data in the sandbox of the client, facilitating the management of the running resources of the device, and improving the running efficiency of the device.

[0078] In some possible implementation manners, the operating system can also interact with the target client to obtain information about the data in the sandbox of the target client, and then determine whether it is necessary to clean the target client.

[0079] See Figure 3 As shown, the data cleaning method provided by the embodiment of the present application includes the following steps:

[0080] S301: The operating system obtains a first cleaning instruction for the data in the sandbox of the target client.

[0081] For the introduction of the target client and the first cleaning instruction, please refer to the specific description of S201 above, which will not be repeated here.

[0082] It should be noted that in some possible implementation manners, the first cleaning instruction may also include a cleaning condition. The cleaning condition is the condition for triggering the target client to execute the cleaning operation. The cleaning condition included in the first cleaning instruction is related to the cleaning requirement. For the introduction of the cleaning condition, please refer to the following text.

[0083] S302: The operating system sends a cleaning information acquisition request to the target client through the inter - process communication interface.

[0084] After the operating system obtains the first cleaning instruction, it first sends a cleaning information acquisition request to the target client. The cleaning information acquisition request is used to request to obtain information about the data in the sandbox of the target client. The data format of the cleaning information acquisition request can be a pre - agreed data format so that the target client can process the cleaning information acquisition request.

[0085] The embodiments of the present application do not limit the specific content included in the cleaning information acquisition request. In a possible implementation, the content included in the cleaning information acquisition request is determined based on the cleaning condition included in the first cleaning instruction. For example, the cleaning condition is that the data type is a preset type. The first cleaning instruction includes the preset type. The cleaning information acquisition request includes a request for the data type of the data in the sandbox. As another example, the cleaning condition is that the data volume is greater than the cleaning threshold. The first cleaning instruction includes the cleaning threshold. The cleaning information acquisition request includes a request for the data volume of the data in the sandbox. In another possible implementation, the content included in the cleaning information acquisition request is preset content. For example, the cleaning information acquisition request includes a request for information on cleanable data among the data in the sandbox of the target client. By using the obtained information on cleanable data, it is possible to determine the data that can be safely cleaned, avoid incorrect data cleaning, and improve the accuracy of data cleaning. The information on cleanable data includes, for example, one or more of the data volume and data type of the cleanable data.

[0086] S303: The target client obtains a cleaning information acquisition request sent by the operating system of the device through an inter-process communication interface.

[0087] S304: The target client sends cleaning information to the operating system through an inter-process communication interface.

[0088] After obtaining the cleaning information acquisition request, the target client processes the cleaning information acquisition request. Based on the situation of the data in the sandbox, cleaning information is generated. The cleaning information includes information on the data in the sandbox of the client.

[0089] The embodiments of the present application do not limit the specific content included in the information on the data in the sandbox of the client. As an example, the content included in the cleaning information generated by the target client can be preset content. For example, it is pre-set that the information on the data in the sandbox includes information on cleanable data. The information on cleanable data includes one or more of the data volume and data type. As another example, the content included in the cleaning information generated by the target client is related to the content included in the cleaning information acquisition request. For example, the cleaning information acquisition request includes a request for the data type. The information on the data in the sandbox generated by the target client includes the data type of the data in the sandbox. As another example, the cleaning information acquisition request includes a request for the data volume. The information on the data in the sandbox generated by the target client includes the data volume of the data in the sandbox.

[0090] In a possible implementation, the cleaning information further includes cleaning interface information of the target client. The cleaning interface is used to clean the data in the sandbox of the target client. The cleaning interface information is used to describe the cleaning interface of the target client.

[0091] S305: The operating system obtains the cleaning information sent by the target client through the inter-process communication interface.

[0092] The operating system processes the obtained cleaning information. It determines whether the cleaning information meets the cleaning conditions. The cleaning conditions are the conditions for triggering the target client to perform the cleaning operation.

[0093] The embodiments of this application do not limit the specific content of the cleaning conditions. In one possible implementation, the cleaning conditions are pre-set fixed cleaning conditions. For example, the data volume of the cleanable data is greater than the cleaning threshold. Another example is that the preset cleaning time is reached. In another possible implementation, the first cleaning instruction includes the cleaning conditions. The cleaning conditions can be configured by the user or the operating system that triggers the generation of the first cleaning instruction, or the cleaning conditions are determined by the cleaning task executed by the one that triggers the generation of the first cleaning instruction.

[0094] As an example, the cleaning conditions are related to the cleanable data. For example, the cleaning condition is that the data volume of the cleanable data is greater than the cleaning threshold. Another example is that the data type of the cleanable data is a preset type.

[0095] S306: The operating system determines that the information of the data in the sandbox meets the cleaning conditions.

[0096] After the operating system determines that the information of the data in the sandbox included in the obtained cleaning information meets the cleaning conditions, it then executes S307. If the operating system determines that the information of the data in the sandbox does not meet the cleaning conditions, it does not send the second cleaning instruction to the target client. In this way, it can be used to judge whether it is necessary to trigger the target client to clean the data, improving the fine degree of control over the data cleaning of the target client.

[0097] S307: The operating system sends the second cleaning instruction to the target client through the inter-process communication interface connected to the target client.

[0098] For the specific description of the second cleaning instruction, please refer to the specific description of the second cleaning instruction in S202 above, which will not be elaborated here.

[0099] In some possible implementations, the cleaning information includes information about the data that can be cleaned. The second cleaning instruction sent by the operating system to the target client is used to instruct the target client to clean the data that can be cleaned. Further, the second cleaning instruction is used to instruct the target client to clean the data that can be cleaned and meets the cleaning conditions. For example, the cleaning condition is that the amount of the data that can be cleaned is greater than the cleaning threshold. The second cleaning instruction is used to instruct the target client to clean all the data that can be cleaned, or to instruct the target client to clean a part of the data that can be cleaned and whose amount is greater than the cleaning threshold. Another example is that the cleaning condition is that the data type of the data that can be cleaned is a preset type. The second cleaning instruction is used to instruct the target client to clean the data that can be cleaned and is of the preset type.

[0100] In addition, when the cleaning information further includes the cleaning interface information of the target client, the operating system can determine the cleaning interface of the target client by using the cleaning interface information. Or, in some possible implementations, the cleaning interface information of the target client is obtained or configured in advance. The operating system can determine the cleaning interface of the target client by using the cleaning interface information.

[0101] An embodiment of the present application provides a possible implementation manner for the operating system to send a second cleaning instruction to the target client, including: the operating system sends a call instruction to the cleaning interface of the target client. The call instruction is used to trigger the call of the cleaning interface to implement the cleaning of the data in the sandbox of the target client. In this way, the cleaning function provided by the client, that is, the cleaning interface of the client, can be used to implement the cleaning of the data in the sandbox of the client, reducing the additional configuration for the cleaning function of the client and lowering the cost.

[0102] S308: In response to the second cleaning instruction sent by the operating system of the device obtained from the inter-process communication interface, the target client cleans the data in the sandbox.

[0103] For the specific description of S308, please refer to the specific description of S203 above, which will not be repeated here.

[0104] When the second cleaning instruction instructs the target client to clean the data that can be cleaned and meets the cleaning conditions, the target client can, based on the second cleaning instruction, clean the data that can be cleaned and meets the cleaning conditions in the sandbox.

[0105] In a possible implementation manner, an embodiment of the present application provides a specific implementation manner for the target client to clean the data in the sandbox in response to the second cleaning instruction sent by the operating system of the device obtained from the inter-process communication interface, including:

[0106] In response to obtaining, from the inter-process communication interface, a call instruction sent by the operating system for the cleaning interface, the cleaning interface is called to clean the data in the sandbox.

[0107] After the target client obtains the call instruction for the cleaning interface from the IPC interface, the cleaning interface is called to clean the data in the sandbox. The embodiments of the present application do not limit the manner in which the cleaning interface cleans the data in the sandbox. In a possible implementation manner, the manner in which the cleaning interface cleans the data is set in advance. The cleaning interface cleans the data in the sandbox based on the preset manner of cleaning the data. In another possible implementation manner, the cleaning interface can perform data cleaning based on the cleaning manner indicated by the call instruction. For example, the call instruction indicates to clean the cleanable data that meets the cleaning conditions. The cleaning interface can, based on the call instruction, clean the cleanable data in the sandbox that meets the cleaning conditions. In this way, the data that needs to be cleaned can be determined more accurately, the probability of cleaning important data that should not be cleaned can be reduced, and the waste of resources caused by over-cleaning can be avoided.

[0108] Based on the relevant content of S301 - S308 above, the operating system interacts with the target client to obtain cleaning information. In this way, fine-grained cleaning of the data in the sandbox of the target client can be achieved, and the degree of control and the accuracy of cleaning of the data in the sandbox of the target client can be improved.

[0109] Based on the data cleaning method for the operating system of a device provided in the above method embodiments, the embodiments of the present application further provide a data cleaning device, which can be applied to the operating system of a device.
