All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It is to be understood that the terms "first," "second," and the like, as used herein, are not specifically intended to be used in a sequential or ordinal sense, nor are they intended to limit the application, and are interchangeable as appropriate, merely to distinguish between components or operations described in the same technical term.

Fig. 1 illustrates a flow of a method for restricting copying of file contents, which may be performed by an apparatus for restricting copying of file contents according to an embodiment of the present application.
As shown in fig. 1, the process specifically includes:
step 101, when determining that the file to be restricted from being copied is in an occupied state, obtaining the process name of the current foreground window of the computer system.
Step 102, if it is determined that the process name of the current foreground window is located in the process name record of the office software, it is determined that the process of the current foreground window is open to the file to be restricted from being copied, and the file name of the file to be restricted from being copied is obtained.
Step 103, determining whether the file name of the file to be limited to copy is in the file name record of the file content limited to copy.
And 104, if the file name of the file to be limited to copy is determined to be in the file name record of the file content limited to copy, limiting copy is carried out on the content of the file to be limited to copy.
In step 101, in order to ensure that the content of the file to be restricted from being copied, the technical solution in the embodiment of the present application needs to detect whether the file to be restricted from being copied is in an occupied state, and if it is determined that the file to be restricted from being copied is in an occupied state, the process name of the current foreground window of the computer system is obtained, so that the consumption of computer system resources caused by obtaining the process name of the current foreground window of the computer system when other files to be restricted from being copied are not in an occupied state can be avoided. If it is determined that the file to be limited and copied is not in the occupied state, in order to avoid the risk of copying the content of the file to be limited and copied, the attribute state of the file to be limited and copied needs to be continuously monitored, so that the copy limiting function can be started in time when the file to be limited and copied opened by the current foreground window process is determined.
Specifically, after determining that the file to be restricted from being copied is in an occupied state, the process identifier of the current foreground window can be timely acquired by utilizing the window process identifier acquisition function, and the process name of the current foreground window matched with the process identifier of the current foreground window can be timely and accurately acquired from a plurality of process names in the computing system based on the window process name acquisition function.
Taking a file needing to be limited to be copied as a text document as an example, the embodiment of the application can judge whether the text document is in an occupied state or not through an ISFileInuser, and if the text document is not in the occupied state, the attribute state of the text document needs to be acquired again; if the text document is in an occupied state, a foreground window handle in the local computer system can be acquired by using GetForeground. Then, a process identification or window title of the subsequent current foreground window may be acquired based on the foreground window handle as a pointer. For example, the process ID of the current foreground window may be obtained by a window process identifier obtaining function (e.g., getWindowThreadProcessId, etc.), and then the process name of the current foreground window that matches the process ID of the current foreground window may be further obtained by a window process name obtaining function (e.g., getProcessNameById, etc.).
It should be noted that, in the embodiment of the present application, the technical scheme is to detect whether the file to be restricted from being copied is in an occupied state; the method has the advantages that aiming at files which do not need to be limited to copy, whether the files are in an occupied state or not is not detected, and the follow-up step of limiting the copy of the file contents is not needed to be executed, so that the limited copy of the file contents is more targeted, the operation flow of limiting the copy is not needed to be executed for each file, the computer system resources consumed by the method flow of executing the scheme for the files which do not need to be limited to copy can be reduced, and the efficiency of limiting the copy of the file contents can be improved. For example, there are three files, namely, a file a, a file B and a file C, wherein, if the content of the specified file a needs to be restricted from being copied, it is only determined whether the file a is in an occupied state for the file a, and whether the file B or the file C is in an occupied state for the file B or the file C. The file requiring copy restriction is a pre-designated file requiring copy restriction.
In step 102, after the process name of the current foreground window of the computer system is obtained, it is determined whether the process name of the current foreground window is located in the process name record of the office software. If the process name of the current foreground window is determined to be in the process name record of the office software, the process of the current foreground window can be accurately confirmed to open the file to be limited from being copied, and meanwhile, the file name of the file to be limited from being copied can be timely obtained. Namely, the window title of the current foreground window is obtained through the window title obtaining function, and the file name of the file to be limited to copy is identified from the window title of the current foreground window, so that support can be provided for limiting copy of the content of the file to be limited to copy, which is opened for the process of the current foreground window or not. If the process name of the current foreground window is determined not to be in the process name record of the office software, confirming that the software type of the current foreground window opened by the process does not belong to the office software, and copying the software content corresponding to the software type of the current foreground window opened by the process is not limited. When the software type of the current foreground window, which is opened by the process, is confirmed not to belong to office software, the software content corresponding to the software type of the current foreground window, which is opened by the process, can be not required to be limited to be copied, and the step of continuously monitoring the attribute state of the file to be limited to be copied can be returned.
The process name record of the office software is determined by the following method: setting a process name of at least one office software, and storing the process name of the at least one office software in a process name record of the office software. Therefore, by presetting the process names of the office software, whether the process name of the current foreground window belongs to the process name of the office software can be conveniently and accurately determined in time, and reliable and accurate support is provided for limiting copying of software contents which are required to be opened for the process of the current foreground window.
Taking a file needing to be limited to copy as an example, if it is determined that the process name of the current foreground window is not located in the process name record of the office software, it is indicated that the software type of the process opening of the current foreground window is not office software, and limited copy is not required for the software content corresponding to the software type of the process opening of the current foreground window. If the process name of the current foreground window is determined to be in the process name record of the office software, the software type for indicating that the process of the current foreground window is opened is office software, so that the window title of the current foreground window can be acquired through a window title acquisition function (such as GetWindow text and the like), and the file name of the text document is identified from the window title.
In the above steps 103 and 104, after the file name of the file to be limited to copy is obtained, it is determined whether the file name of the file to be limited to copy is located in the file name record of the file content limited to copy. If the file name of the file to be limited to copy is determined to be in the file name record of the file content limited to copy, limiting copy is carried out on the content of the file to be limited to copy; if it is determined that the file name of the file to be restricted from copying is not located in the file name record of the file content restricted from copying, it is not necessary to restrict copying with respect to the content of the file to be restricted from copying.
Wherein the file name record of the file content limited copy is determined by: setting a file name of at least one file content requiring copy restriction, and storing the file name of at least one file content requiring copy restriction in a file name record of the file content requiring copy restriction. Therefore, the file names of the file contents needing to be limited for copying are preset, so that support can be provided for the follow-up timely and accurate determination of whether the software contents which need to be opened for the process of the current foreground window are limited for copying.
Taking a file requiring copy restriction as an example, the method further includes determining whether the file name of the text document is in a file name record of file content copy restriction after the file name of the text document is acquired, that is, determining whether the file name of the text document belongs to the file restricted from copy. If the file name of the text document does not belong to the document which is limited to be copied, the file name indicates that the limited copy is not required for the content of the text document opened by the current office software window interface; if the file name of the text document belongs to the document which is limited to be copied, the text document which is opened by the current office software window interface needs to enable the copy limiting function so as to be capable of timely limiting the copy of the content of the text document which is opened by the current office software window interface, thereby realizing the copy limiting function for a certain text document or a certain type of text document, having good portability, and further solving the problems that in the prior art, the copy limiting of a single document or a certain batch of documents cannot be performed due to the global copy function of a computer system which is limited by the starting process.
In order to better explain the embodiment of the method for restricting copying of file contents of the present application, the following describes the flow of another method for restricting copying of file contents provided by the embodiment of the present application through a specific implementation scenario.
As shown in fig. 2, the process includes the steps of:
step 201, it is determined whether the file to be restricted from being copied is in an occupied state. If yes, go to step 202; and if not, re-acquiring the attribute state of the file to be restricted from being copied.
Step 202, obtaining the process name of the current foreground window.
Step 203, it is determined whether the process name of the current foreground window is the process name of the office software. If yes, go to step 204; if not, go to step 201.
Step 204, obtaining the file name of the file opened by the process of the current office software.
Step 205, it is determined whether the file name of the file belongs to the file name of which copying is restricted. If yes, go to step 206; if not, go to step 201.
And 206, limiting the content of the file opened by the current foreground window interface, and not allowing copying.
The above embodiment shows that, by acquiring the process name of the current foreground window of the computer system only when the file to be restricted from copying is determined to be in the occupied state, the consumption of computer system resources caused by acquiring the process name of the current foreground window of the computer system when other files not restricted from copying are in the occupied state can be avoided. Then, if the process name of the current foreground window is determined to be in the process name record of the office software, it can be accurately confirmed that the process of the current foreground window opens the file to be limited from being copied, and meanwhile, the file name of the file to be limited from being copied can be timely obtained, so that when the file name of the file to be limited from being copied is determined to be in the file name record of the file content limited from being copied, the limited copying of the content of the file to be limited from being copied is realized. Therefore, the scheme can realize the copy limiting function of a certain copy limiting file without setting a password for each copy limiting file, and can simultaneously prevent copy limiting for other copy limiting files, thereby ensuring the high efficiency and convenience of file content copy limiting, ensuring the safety of the content of the copy limiting file, and reducing the risk of leakage of the content of the copy limiting file. In addition, when the copying is limited for the files needing to be limited, the scheme does not influence the normal use of the copying function of other applications in the local computer system, and has good compatibility.
