[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.

[0059] In order to protect the security of a user's sensitive information when the screenshot function of an electronic device is used, the present application provides a screenshot method, apparatus, device and medium.

[0060] Example 1:

[0061] All implementation methods of the embodiments of this application comply with the relevant provisions of national laws and regulations regarding the acquisition, storage, use, and processing of data.

[0062] Figure 1 A schematic diagram of a first screenshot process provided by some embodiments is shown, such as Figure 1 As shown, the process includes the following steps:

[0063] S101: Performing a screenshot of the current display interface according to the received screenshot instruction, and obtaining data information corresponding to the current display interface.

[0064] The screenshot method provided in the embodiment of the present application is applied to an electronic device, which may be, for example, a PC, a mobile terminal, or a server. In one possible implementation, the screenshot method provided in the embodiment of the present application may be applied to an electronic device installed with an iOS system.

[0065] In one possible implementation, when a user needs to take a screenshot of the current display interface of an electronic device, a screenshot command can be triggered in the electronic device, and the electronic device can receive the screenshot command. After receiving the screenshot command, the electronic device can take a screenshot of the current display interface according to the received screenshot command and obtain data information corresponding to the current display interface. For example, the electronic device can obtain data information such as a binary data stream corresponding to the current display interface.

[0066] S102: Determine whether the current display interface includes a sensitive information input field. If so, modify the sub-data information corresponding to the information in the sensitive information input field in the data information.

[0067] In order to protect the security of the user's sensitive information when the screenshot function of the electronic device is used, the electronic device can determine whether the current display interface contains a sensitive information input field. In one possible implementation, when determining whether the current display interface contains a sensitive information input field, it can be determined whether any input field included in the current display interface is configured with a preset screenshot privacy protection control. If any input field included in the current display interface is configured with a preset screenshot privacy protection control, it can be determined that the current display interface contains a sensitive information input field. If any input field included in the current display interface is not configured with a preset screenshot privacy protection control, it can be determined that the current display interface does not contain a sensitive information input field.

[0068] In a possible implementation, if the current display interface includes a sensitive information input field, the electronic device may modify the sub-data information corresponding to the information in the sensitive information input field in the acquired data information corresponding to the current display interface.

[0069] It is understandable that if the current display interface does not contain a sensitive information input field, the electronic device may not modify the data information corresponding to the current display interface obtained, and may directly generate and display a screenshot image of the current display interface based on the binary data stream and other data information obtained from the current display interface.

[0070] S103: Generate and display a screenshot image based on the modified data information.

[0071] In one possible implementation, after the electronic device modifies the sub-data information corresponding to the information in the sensitive information input field, when the electronic device generates a screenshot image based on the modified data information, the sub-image of the area where the sensitive information input field is located in the screenshot image can be a blank, black, mosaic or other blurred image. This application does not specifically limit the method of modifying the sub-data information, and it can be flexibly set according to needs.

[0072] For example, assuming the current display interface contains a sensitive information input field for an ID number, regardless of whether the user's ID number is entered in the sensitive information input field, the sub-data information corresponding to the information in the sensitive information input field can be modified so that, in the screenshot generated based on the modified data information, the sub-image corresponding to the sensitive information input field for the ID number can be a blank or blurred image. Because the sub-image corresponding to the area where the sensitive information input field is located in the screenshot is a processed blurred image and does not display the user's specific sensitive information, the screenshot generated based on the modified data information can effectively protect the user's sensitive information.

[0073] For ease of understanding, the screenshot process provided by this application is illustrated below through a specific embodiment. Figure 2 A schematic diagram of a second screenshot process provided by some embodiments is shown, such as Figure 2 As shown, the process includes the following steps:

[0074] S201: Taking a screenshot of the current display interface according to the received screenshot instruction, and obtaining data information corresponding to the current display interface.

[0075] S202: Determine whether a preset screenshot privacy protection control is configured in any input field included in the current display interface. If so, proceed to S203; if not, proceed to S205.

[0076] S203: Determine whether the current display interface includes a sensitive information input field, and modify the sub-data information corresponding to the information in the sensitive information input field in the data information.

[0077] S204: Generate and display a screenshot image based on the modified data information.

[0078] S205: Determine that the current display interface does not include a sensitive information input field, and directly generate and display a screenshot image based on the data information obtained in S201.

[0079] Since the present application can take a screenshot of the current display interface according to the received screenshot instruction, obtain the data information corresponding to the current display interface; determine whether the current display interface contains a sensitive information input field, and if so, modify the sub-data information corresponding to the information in the sensitive information input field in the data information; and generate and display a screenshot image based on the modified data information, so that the user's sensitive information will not be displayed in the screenshot obtained by the screenshot, that is, the user's sensitive information will not be saved as a screenshot, thereby protecting the security of the user's sensitive information when the screenshot function of the electronic device is used.

[0080] Example 2:

[0081] All implementation methods of the embodiments of this application comply with the relevant provisions of national laws and regulations regarding the acquisition, storage, use, and processing of data.

[0082] In order to configure the screenshot privacy protection control, based on the above embodiment, in the embodiment of the present application, the process of pre-configuring the screenshot privacy protection control includes:

[0083] Create a secure screenshot container;

[0084] Adding a text input box tool to the secure screenshot container and setting the text input box tool to a ciphertext display state; wherein the text input box tool contains an encrypted information protection sub-container;

[0085] Add an encryption information protection control to the encryption information protection sub-container in the text input box tool.

[0086] In one possible implementation, a screenshot privacy protection control can be created based on a secure screenshot container developed based on the native system control of the iOS system. Exemplarily, the secure screenshot container may include SIPCView, and a screenshot privacy protection control can be created based on the secure screenshot container SIPCView developed based on the native system control of the iOS system. Since the present application can create a screenshot privacy protection control based on a secure screenshot container (SIPCView) developed based on the native system control of the iOS system, when the user's sensitive information is protected based on the screenshot privacy protection control, the electronic device can have a higher execution efficiency, and in addition, the application scenario of the screenshot method can be wider.

[0087] Figure 3 A schematic diagram of a screenshot privacy protection control provided by some embodiments is shown. Figure 3 As shown, in one possible implementation, when configuring the screenshot privacy protection control, a secure screenshot container (SIPCView) can be created first; then, a text input box tool can be added to the secure screenshot container (SIPCView). Exemplarily, the text input box tool can include a UITextField, and the text input box tool UITextField can be added to the secure screenshot container (SIPCView). In one possible implementation, in order to configure the sub-image of the area where the sensitive information input field in the screenshot image is located as a blurred image, so as to protect the security of the user's sensitive information when the screenshot function is used, the display state of the text input box tool (UITextField) can be set to a ciphertext display state.

[0088] In one possible implementation, the text input box tool may include an encrypted information protection subcontainer, and based on the encrypted information protection subcontainer, the sub-image of the area where the sensitive information input field is located in the screenshot image may be configured as a blurred image, thereby achieving the purpose of protecting the security of the user's sensitive information when the screenshot function is used. In one possible implementation, the sub-controls contained in the text input box tool (UITextField) may be traversed to determine the location of the encrypted information protection subcontainer in the text input box tool (UITextField) that can implement screenshot protection (ciphertext display). Then, the encrypted information protection control is added to the encrypted information protection subcontainer in the text input box tool (UITextField), thereby completing the configuration (assembly) of the screenshot privacy protection control. In one possible implementation, the encrypted information protection control may include SIPCContentView, and the encrypted information protection control SIPCContentView may be added to the encrypted information protection subcontainer in the text input box tool (UITextField).

[0089] For ease of understanding, the process of configuring the screenshot privacy protection control in this application is described below through a specific embodiment. Figure 4 A schematic diagram of a process for configuring a screenshot privacy protection control provided by some embodiments is shown. Figure 4 As shown, in one possible implementation, when configuring the screenshot privacy protection control, you can first traverse the sub-controls contained in the text input box tool (UITextField) to determine the location of the encrypted information protection sub-container in the text input box tool (UITextField) that can implement screenshot protection (ciphertext display). At the same time, create a secure screenshot container (SIPCView), add the text input box tool (UITextField) to the secure screenshot container (SIPCView), and set the display state of the text input box tool (UITextField) to the ciphertext display state. Then, add the encrypted information protection control (SIPCContentView) to the encrypted information protection sub-container in the text input box tool (UITextField), thereby realizing (completing) the configuration (assembly) of the screenshot privacy protection control.

[0090] For ease of understanding, the screenshot process provided by this application is explained below through a specific embodiment. Figure 5 A third screenshot process diagram provided by some embodiments is shown. Figure 5 As shown, the process includes the following steps:

[0091] S501: Create a secure screenshot container SIPCView.

[0092] S502: Add a text input box tool UITextField to SIPCView, and set the UITextField to the ciphertext display state.

[0093] S503: Add the encrypted information protection control SIPCContentView to the encrypted information protection subcontainer in the UITextField to complete the configuration (assembly) of the screenshot privacy protection control.

[0094] S504: Configuring a screenshot privacy protection control in an input field in the display interface of the App.

[0095] S505: Performing a screenshot of the current display interface according to the received screenshot instruction, and obtaining data information corresponding to the current display interface.

[0096] S506: Determine whether a preset screenshot privacy protection control is configured in any input field included in the current display interface. If so, proceed to S507; if not, proceed to S509.

[0097] S507: Determine whether the current display interface includes a sensitive information input field, and modify the sub-data information corresponding to the information in the sensitive information input field in the data information.

[0098] S508: Generate and display a screenshot image based on the modified data information.

[0099] S509: Determine that the current display interface does not include a sensitive information input field, and directly generate and display a screenshot image based on the acquired data information.

[0100] Example 3:

[0101] All implementation methods of the embodiments of this application comply with the relevant provisions of national laws and regulations regarding the acquisition, storage, use, and processing of data.

[0102] In order to configure the screenshot privacy protection control in the input field, based on the above embodiments, in the embodiment of the present application, the process of configuring the screenshot privacy protection control in the input field includes:

[0103] If the screenshot privacy protection control is added to the input box of the preset field, the sub-control corresponding to the input box of the preset field is added to the screenshot privacy protection control.

[0104] In one possible implementation, when configuring a screenshot privacy protection control in an input field, the control can be manually configured in the input field. Since manual configuration of the screenshot privacy protection control in an input field is typically performed only on one input field at a time, for ease of description, the manual configuration of the screenshot privacy protection control in an input field is referred to as "individual addition." Figure 6 A schematic diagram of a process for adding a separate screenshot privacy protection control is shown in some embodiments. Figure 6 As shown, the electronic device displays the display page in the App that requires screenshot privacy protection, and the user manually configures the screenshot privacy protection control to the location of the input bar of the fields that require screenshot privacy protection, such as ID number, password, etc. (for the convenience of description, called preset fields); at the same time, the sub-control corresponding to the input bar of the preset field can be added to the screenshot privacy protection control, thereby realizing (completing) the configuration of the screenshot privacy protection control in the input bar.

[0105] In a possible implementation, in order to quickly and intelligently configure the screenshot privacy protection control in the input field, the screenshot privacy protection control may be automatically and intelligently configured in the input field based on the electronic device. Figure 7 A schematic diagram of a process for intelligently configuring a screenshot privacy protection control in an input field is shown in some embodiments. Figure 7 As shown, for example, the user can pre-configure fields such as ID number and password as preset fields. The electronic device can recognize the preset fields contained in the display interface and add a screenshot privacy protection control in the input box of the preset field. At the same time, the electronic device can also add the sub-control corresponding to the input box of the preset field to the screenshot privacy protection control, thereby realizing (completing) the configuration of the screenshot privacy protection control in the input bar.

[0106] In one possible implementation, Figure 8 A schematic diagram of a screenshot privacy protection control configured in an input box provided by some embodiments is shown. Figure 8 As shown, taking the encrypted information protection control as SIPCContentView as an example, the SIPCContentView in the screenshot privacy protection control can be used to carry the sub-control corresponding to the input field. When adding the sub-control corresponding to the input field contained in the display interface to the screenshot privacy protection control, the sub-control corresponding to the input field can be added to the SIPCContentView in the screenshot privacy protection control.

[0107] Example 4:

[0108] All implementation methods of the embodiments of this application comply with the relevant provisions of national laws and regulations regarding the acquisition, storage, use, and processing of data.

[0109] In order to quickly and intelligently configure the screenshot privacy protection control in the input field, based on the above embodiments, in the embodiment of the present application, the process of configuring the screenshot privacy protection control in the input field includes:

[0110] If any display interface is detected to be called, the sub-controls corresponding to each input field contained in the display interface are added to the screenshot privacy protection control respectively, and the screenshot privacy protection control is configured at the position of each input field respectively.

[0111] In a possible implementation, in order to quickly and intelligently configure the screenshot privacy protection control in the input bar, the screenshot privacy protection control can be configured in each input bar contained in the display interface in an intelligent and batch manner based on the electronic device. For the convenience of description, the method of configuring the screenshot privacy protection control in each input bar contained in the display interface is referred to as global addition (batch addition). In addition, when the screenshot function of the electronic device in the related art is used, the user's sensitive information may be screenshoted and saved (for the convenience of description, it is referred to as not having a screenshot protection function) is referred to as method one, and when the screenshot function of the electronic device in this application is used, the user's sensitive information can be protected (for the convenience of description, it is referred to as having a screenshot protection function) is referred to as method two.

[0112] Since the method usually adopted by the electronic device by default is method one in the related art that does not have a screenshot protection function, if you want the electronic device to adopt method two in this application that has a screenshot protection function, you need to change (transform) the method implementation corresponding to method one (for the convenience of description, referred to as method implementation one) to the method implementation corresponding to method two (for the convenience of description, referred to as method implementation two). In one possible implementation, based on the idea of ​​aspect-oriented programming (AOP), the runtime mechanism can be used to dynamically change the method implementation one of the lifecycle method (method one) that has been displayed by the controller in the electronic device to the method implementation two corresponding to method two (for the convenience of description, referred to as dynamic exchange method).

[0113] Figure 9 A schematic diagram of a dynamic switching method provided by some embodiments is shown. Figure 9 As shown, since electronic devices have a method cache queue for each class object to store the mapping relationship (correspondence) between the method name in the method name list and the method implementation in the method implementation list, what needs to be done to dynamically exchange methods is to use the Runtime mechanism to dynamically change the mapping relationship between the method name and the method implementation, see Figure 9That is, the Runtime mechanism can be used to change the method implementation one corresponding to method one (method name one) to method implementation two (method implementation with screenshot protection function), and change method implementation one (method implementation without screenshot protection function in related technology) to the method implementation corresponding to method two (method name two).

[0114] Since the method implementation corresponding to method one is usually the method implementation adopted by electronic devices, when the method implementation of method one corresponding to the App display interface is changed (transformed) into method implementation two (method implementation with screenshot protection function), the electronic device can use the screenshot method with screenshot protection function in this application to take a screenshot of the App display interface, so that when taking a screenshot of the App display interface, the user's sensitive information will not be displayed in the screenshot, that is, the user's sensitive information will not be captured and saved, thereby protecting the security of the user's sensitive information when the screenshot function of the electronic device is used.

[0115] It is understandable that if the display interface of the App does not perform the steps of the above-mentioned dynamic exchange method, when the electronic device takes a screenshot of the display interface in the App, the screenshot method without the screenshot protection function in method one can still be used.

[0116] In a possible implementation, when using the Runtime mechanism to perform the steps of the dynamic exchange method based on the idea of ​​AOP, considering that each display interface usually has operations that are called and displayed, the electronic device can add the sub-controls corresponding to each input field contained in the display interface to the screenshot privacy protection control when it monitors that any display interface is called, and configure the screenshot privacy protection control to the position of each input field, so as to configure the screenshot privacy protection control in each input field, that is, to implement the steps of the above-mentioned dynamic exchange method.

[0117] Similar to the above embodiment, in a possible implementation, taking the encrypted information protection control as SIPCContentView as an example, the sub-controls corresponding to each input field contained in the display interface can be added to the SIPCContentView in the screenshot privacy protection control.

[0118] For ease of understanding, the dynamic switching method process provided by this application is explained below through a specific embodiment. Figure 10 A schematic diagram of a dynamic switching method provided by some embodiments is shown. Figure 10 As shown, the process includes the following steps:

[0119] First call the original life cycle method, that is, call method one first. At this time, the method implementation corresponding to method one is method implementation one (a method implementation that does not have a screenshot protection function in the related art), and the dynamic exchange method can be started at the same time.

[0120] In one possible implementation, the process of the dynamic swap method may include: when monitoring the display interface being called, all sub-controls contained in the display interface (sub-controls corresponding to all input boxes) can be traversed, and then the sub-controls corresponding to all input boxes are added to the screenshot privacy protection control respectively, and the screenshot privacy protection control is configured at the location of each input box respectively, thereby completing (implementing) the steps of the dynamic swap method.

[0121] Figure 11 A fourth screenshot process diagram provided by some embodiments is shown, such as Figure 11 As shown, the process includes the following steps:

[0122] S1101: Performing a screenshot of the current display interface according to the received screenshot instruction, and obtaining data information corresponding to the current display interface.

[0123] S1102: Determine whether the current display interface has completed (implemented) the steps of the dynamic exchange method. If so, proceed to S1103; if not, proceed to S1105.

[0124] S1103: The input field configured with the preset screenshot privacy protection control in the current display interface is used as the sensitive information input field, and the sub-data information corresponding to the information in the sensitive information input field in the acquired data information corresponding to the current display interface is modified.

[0125] S1104: Generate and display a screenshot image based on the modified data information, that is, take a screenshot using the method with the screenshot protection function in this application.

[0126] S1105: directly generating and displaying a screenshot image based on the acquired data information corresponding to the current display interface, that is, taking a screenshot in a manner without a screenshot protection function in related technologies.
