[0044] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0045] It should be pointed out that the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0046] The embodiment of the present invention provides a method for window filtering, which can be executed by a terminal device, such as Figure 1 As shown, the method includes the following steps.

[0047] S101: Obtaining a handle of a top-level window that is at the top in display order among windows included in a terminal device.

[0048] When a user uses a terminal device, multiple windows can be opened at the same time. The windows are usually displayed in the order of user operations. That is, the window most recently operated by the user is usually displayed at the top. The closer the time of the last window operated by the user is to the current time, the closer the window is to the top.

[0049] In a terminal device, multiple open windows can form an overlapping window stack. The display order of each window in the window stack can be positioned along an imaginary axis, which extends outward from the screen of the terminal device and can be called the "Z axis". Therefore, the display order of each window in the window stack can also be called the "Z order". The window at the top of the Z order, that is, the top window, covers all other windows, and the window at the bottom of the Z order is covered by all other windows.

[0050] In this step, the terminal device obtains the handle of the window at the top of the display order, that is, the handle of the window at the top of the “Z order.” Specifically, the terminal device can implement this step by calling a system API, for example, the system API that can be called is GetTopWindow.

[0051] It should be noted that the form may include a programming window and a dialog box corresponding to the application. Since a new form may pop up in the terminal device as the user operates, the program is executed, etc., in order to ensure the comprehensiveness of the filtering of each form in the terminal device, the form filtering method in the embodiment of the present invention can be executed periodically, such as periodically obtaining the handle of the top-level form in the display order of each form included in the terminal device, and then executing the subsequent steps. The specific value of the period can be set according to the specific application scenario.

[0052] S102: According to the handle of the top-level window, the handles of other windows included in the terminal device are obtained in sequence.

[0053] Among them, after obtaining the handle of the top-level window, the handle of the next layer of window of the top-level window can be obtained according to the handle of the top-level window. By executing in this way in a loop, the handles of other windows included in the terminal device can be obtained in turn. Therefore, through steps S101 and S102, the handles of all windows included in the terminal device can be obtained.

[0054] Specifically, this step can be executed as follows: based on the handle of the top-level window, obtain the handle of the sub-level window that is displayed after the top-level window and adjacent to the top-level window; and based on the handle of the sub-level window, obtain the handle of the next window that is displayed after the sub-level window and adjacent to the sub-level window, until the handles of the windows included in the terminal device are obtained.

[0055] Since the handle of the window in the previous layer of the display order can be used to obtain the handle of the adjacent window in the next layer of the display order, in this step, the handle of the second layer of the window can be obtained by first using the handle of the top-level window, and then the handle of the next layer of the window can be obtained based on the handle of the second-level window. This cycle can be repeated to obtain the handle of each window in the display order from the top layer to the bottom layer, that is, the handles of each window included in the terminal device can be obtained.

[0056] It should be noted that in the embodiment of the present invention, the terminal device obtains the handle of the window in the next layer according to the handle of the window in the previous layer in the display order by calling the system API. For example, the system API that can be called is GetNextWindow.

[0057] S103: Determine the file information of the application corresponding to each window and the display information of each window according to the handle of each window included in the terminal device.

[0058] The window handle is a reference to a system internal data structure, which may include window title, name, display area, display status and other display information related to the window, so the window display information can be determined through the window handle. In addition, in the terminal device, a correspondence between the window handle and the corresponding application of the window can be established for each window, so the application corresponding to the window can be determined through the window handle, and then the file information of the application can be determined.

[0059] Specifically, the display information includes the name of the window, the display state and / or the relative position to the screen of the terminal device; the file information includes the properties of the application and / or the file signature of the application.

[0060] The display information indicates the associated information when the form is displayed, such as the name, title, logo, display status, relative position to the screen of the terminal device, etc. The display status may include display and hide, display means that the form is currently displayed on the screen of the terminal device, and hide means that the form is currently hidden in the screen of the terminal device. The relative position to the screen of the terminal device indicates the position of the form in the screen of the terminal device, which may be referred to as the display area. The attributes of the application may include multiple types, such as name, version number, description information, MD5 identification code, etc., and the file signature of the application may also include multiple types, such as a digital signature.

[0061] It should be noted that some parameters included in the file information of the application are calculated by a preset algorithm, for example, MD5 identification code and digital signature. MD5 identification code refers to a unique identification code calculated by the MD5 algorithm for the file corresponding to the application. The MD5 algorithm is a preset algorithm. In the embodiment of the present invention, other algorithms can also be preset to calculate the unique identification code. Digital signature refers to a file corresponding to the application calculated by a preset algorithm. The preset algorithm can include multiple types.

[0062] In the embodiment of the present invention, each window establishes a correspondence between the window handle and the application corresponding to the window, which can be established by the process running the application. For example, when the window is running, there is a mapping relationship between its handle and the corresponding process, so the PID (unique identifier of the program process in the operating system) of the process corresponding to the window can be obtained according to the window handle, and then the application corresponding to the process can be determined through the PID of the process, that is, the correspondence between the window handle and the application corresponding to the window is established.

[0063] In the embodiment of the present invention, the method of determining the display information of a window according to the handle of each window can be implemented by calling a system API. For example, when determining the display area of ​​a window, it can be implemented by calling the system API: GetWindowRect, and when determining the name and title of the window, it can be implemented by calling the system API: GetWindowText. The method of determining the file information of the application corresponding to the window according to the handle of each window can also be implemented by calling a system API. For example, when determining the PID of the process corresponding to the window, it can be implemented by calling the system API: GetWindowThrea dProcessId, and when determining the file information, it can be implemented by calling the system API: GetFileVersionInfo.

[0064] S104: Filter each window according to the preset filtering strategy, file information and display information.

[0065] The filtering policy indicates the policy information for filtering the window, which may include target display information and target file information. The target display information indicates the display information of the filtered window, and the target file information indicates the file information of the filtered window. For example, in the embodiment of the present invention, if it is necessary to filter out the window corresponding to a certain application, the attribute of the application can be determined as the target file information, so that the window of the application can be filtered out from the windows included in the terminal device in this step.

[0066] The filtering strategy is preset and can be set according to user needs. Specifically, the preset filtering strategy can be obtained from the server and stored so as to be used for filtering the form in this step.

[0067] Therefore, before executing this step, the following steps may also be performed: sending a filtering policy request to the server; receiving response information sent by the server, and updating the preset filtering policy according to the response information.

[0068] The terminal device can send a filtering policy request to the server to request the filtering policy of the window in the server. After receiving the request from the terminal device, the server can send the stored filtering policy to the terminal device, that is, send a response message to the terminal device, and the response message includes the filtering policy. After receiving the response message, the terminal device can update the preset filtering policy in the terminal device according to the filtering policy in the response message. Among them, if the terminal device sends a filtering policy request to the server for the first time, the filtering policy in the response message can be directly stored as the preset filtering policy, which is equivalent to updating the preset filtering policy. Specifically, a network interface can be established between the terminal device and the server, and then the terminal device and the server can exchange data through the network interface.

[0069] It should be noted that the terminal device may also pre-set corresponding operations for the filtered windows, such as hiding, closing, etc. In this step, the set corresponding operations may be directly executed after the windows are filtered out, and no other operations may be performed on the filtered windows, and normal processing may be sufficient.

[0070] In an embodiment of the present invention, the terminal device can first obtain the handle of the top-level window in the top layer of the display order, and then can sequentially obtain the handles of each window included based on the handle of the top-level window, and then determine the display information of the window and the file information of the corresponding application according to the handle of each window, so as to achieve filtering of each window in the terminal device in combination with the preset strategy. In this way, in an embodiment of the present invention, the handles of each window are obtained according to the handle of the top-level window, and then the file information and display information of the application corresponding to each window can be determined, and filtering of each window is achieved based on the file information and display information, so that each window in the terminal device can be filtered, thereby improving the comprehensiveness of window filtering, and filtering the window from both the file information and the display information, thereby improving the accuracy of window filtering.

[0071] It should be noted that the preset filtering strategy may include target display information and target file information, and the target display information and target file information may also include a variety of information for filtering. When performing window filtering in step S104, it is usually determined in turn whether the display information and file information of the window meet the target display information and target file information, and then the filtered window is determined. Among them, when filtering the window, when it is determined that a certain information of the window meets the target information in the preset filtering strategy, the window can be determined as the filtered window, and the preset filtering strategy that has not been executed subsequently does not need to be executed again.

[0072] Specifically, the following is combined Figure 1 In the embodiment shown in FIG. 1 , the method for filtering the form in step S104 is specifically described in the embodiment of the present invention. Since step S104 needs to be executed for each form, the execution process of any form is described as an example in the embodiment of the present invention. Figure 2 As shown, the method includes the following steps.

[0073] S201: Determine whether the display information of the window meets the target display information.

[0074] In this step, the window may be filtered according to its displayed information.

[0075] The display information may include the name, title, display area, display status, etc. of the window, and the target display information may include the name, title, display area, display status, etc. of the window that needs to be filtered out. For example, in the embodiment of the present invention, it is necessary to filter out the window in the specified area, and the specified area can be determined as the target display information, so that it can be judged in this step whether the display area of ​​the window is the specified area. If it is, it can be directly determined that the window is a filtered window, that is, a filtered window, and step S204 is executed; if not, step S202 can be executed to continue to judge. For another example, in the embodiment of the present invention, it is necessary to filter out the window with a specified title, and the title can be determined as the target display information, so that it can be judged in this step whether the title of the window is the specified title. If it is, it can be directly determined that the window is a filtered window, and step S204 is executed; if not, step S202 can be executed to continue to judge.

[0076] It should be noted that the target display information may include multiple parameters. In this step, the window needs to be judged according to each parameter in the target display information. After determining that the display information of the window does not meet the parameters in the target display information, it can be determined that the display information of the window does not meet the target display information, and step S202 is executed. Otherwise, step S204 is executed.

[0077] S202: If not, determine whether the file information of the application corresponding to the window satisfies the target file information.

[0078] After determining that the target information of the window does not meet the target display information, it is also necessary to determine whether the file information of the application corresponding to the window meets the target file information.

[0079] The file information may include the properties of the application and the file signature of the application, etc., and the target file information may include the properties and the corresponding application corresponding to the form to be filtered out. For example, in the embodiment of the present invention, it is necessary to filter out the form with an illegal digital signature, and then an illegal digital signature library may be set to determine it as the target file information, so that in this step, it can be determined whether the file signature of the corresponding application in the file information of the form belongs to the illegal digital signature library. If so, the form can be directly determined to be a filtered form, and step S204 is executed; if not, the judgment can be continued, or step S203 is executed to determine it is a normal form. For another example, in the embodiment of the present invention, it is necessary to filter out the form corresponding to the specified application, and then the name of the specified application can be set as the target file information, so that in this step, it can be determined whether the file name of the corresponding application in the file information of the form is the name of the specified application. If so, the form can be directly determined to be a filtered form, and step S204 is executed; if not, the judgment can be continued, or step S203 is executed to determine it is a normal form.

[0080] It should be noted that the target display information may include multiple parameters. In this step, the window needs to be judged according to each parameter in the target display information. After determining that the display information of the window does not meet the parameters in the target display information, it can be determined that the display information of the window does not meet the target display information, and step S202 is executed. Otherwise, step S204 is executed.

[0081] S203: If not, determine that the window is a normal window.

[0082] The normal windows refer to windows that do not need to be filtered out. For these windows, the embodiment of the present invention does not need to process them and can be executed normally.

[0083] S204: If yes, determine that the window is a filtered window, and perform an operation corresponding to the filtered window.

[0084] The filtered window indicates the window that needs to be filtered out. In the embodiment of the present invention, operations corresponding to the filtered window can be pre-set, so after the filtered window is determined, the operation corresponding to the filtered window can be performed on it.

[0085] In an embodiment of the present invention, each window is filtered according to the file information and display information of the window, so that each window in the terminal device can be filtered, which improves the comprehensiveness of window filtering, and filters the window from both file information and display information to improve the accuracy of window filtering.

[0086] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a window filtering device 300, such as Figure 3 As shown, the device 300 includes:

[0087] The acquisition unit 301 is used to acquire the handle of the top-level window which is at the top level in the display order among the windows included in the terminal device;
