With the popularization of intelligent terminals, the office work in a mode of carrying a Device (BYOD) by itself is more and more widely applied. BYOD means that office software of many companies is installed on a user's own terminal device so that the user can use company resources to work without being limited by time, place, equipment, personnel, network environment, and the like.
Office software of a company is generally installed on terminal equipment such as a personal computer, a mobile phone, a tablet computer and the like in an application form. In order to ensure the data security of mobile office, it is necessary to ensure that enterprise data such as text and pictures in office applications are not pasted into other applications installed on a terminal device through the copy function of the device.
In order to prevent the protected enterprise data in office applications from being pasted into other applications through the copy function of the device, the currently commonly adopted method is as follows: the user is prohibited from triggering a control event of the device by long pressing the screen of the device. However, since the control event of the device triggered by long pressing the device screen includes not only copying but also other functions such as selecting, sharing, collecting, reminding, deleting, downloading, adding to mail, etc., if the method of triggering the event of the device by long pressing the device screen by the user to prevent the contents from being copied to each other between the applications is prohibited, other control events are also prohibited.

Detailed Description
In the related art, a method for prohibiting a user from copying contents in a protected application to other applications is provided, which empties a clipboard storage space when a page in the application is closed or when the page in the application is shifted from a foreground operation to a background operation, so that the contents displayed in the page cannot be copied to other places. Although the method can prevent the content in the application from being copied to the second application, the content in different pages in the same application cannot be copied with each other. Meanwhile, when the user copies content from the second application a and pastes the content into the second application B, if the user opens the first application before pasting the content into the application B, even if the copy or cut operation of the content is not performed in the first application, when the first application is closed, the content in the second application a stored in the clipboard storage space is emptied, and the content in the second application a cannot be pasted into the second application B, and the copy or cut operation needs to be performed again in the second application a, which affects user experience.
Different from the prior art, the embodiment of the invention monitors the entry event and the exit event of the first application, and when the exit event of the first application is monitored, the first content in the clipboard storage space is stored in the first storage space corresponding to the first application, and the clipboard storage space is cleared, so that the content in the first application cannot be copied to the second application; when the first application entering event is monitored, the first content in the first storage space corresponding to the first application is stored in the clipboard storage space, so that the user can realize the copying of the content in the same first application, the content in the first application is prevented from being copied into the second application, and other control events triggered by the user pressing the device screen for a long time cannot be influenced.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic flow chart of a content copying method according to an embodiment of the present invention. In the embodiment of the present invention, the main body responsible for executing the content copying method may be the terminal device installed with the first application, or may be the first application. The method is described below with an execution subject as a terminal device, and includes the following steps:
s101: and monitoring an entry event and an exit event of the first application.
In this embodiment, the first application is a content-protected application, i.e., the content in the first application cannot be copied to other applications; the second application is an application whose content is not protected, i.e. the content in the second application can be copied to other applications.
Here, the entry event of the first application may include the following cases:
in one case, the first application enters the active state from the inactive state. Optionally, at this time, a human-computer interaction interface of the first application may be displayed to the user; or,
another situation may be that the first application is already started at this time, and it is monitored that the first application enters the foreground running state from the background running state, that is, it is considered that an entry event of the first application is detected. The two situations are collectively called as a first application entry in the invention.
The exit event may include the following: in one case, the first application enters a complete exit state from a foreground running state; or,
in another case, the first application enters the background running state from the foreground running state, and the two cases are collectively referred to as the exit of the first application in the present invention.
S102: when the exit event of the first application is monitored, the first content in the clipboard storage space is stored in the first storage space corresponding to the first application, and the clipboard storage space is emptied.
In a specific implementation, the clipboard storage space is a storage space provided by the operating system of the terminal device for temporarily storing the copied content or the cut content for the copy event and the cut event. The first storage space is a storage space provided by the operating system of the terminal device for the first application, and is used for temporarily storing the first content copied or cut by the user from the first application.
The first content is the content which is copied to the clipboard storage space by a user through triggering a copy event or a cut event, and comprises text, pictures and the like which can be copied.
Here, the first content in the clipboard storage space may be saved to the first storage space corresponding to the first application in the following manner:
when the terminal device monitors the exit event of the first application, whether the first content exists in the storage space of the clipboard is detected by detecting whether a copy event or a cut event is triggered after the first application is monitored to enter the terminal device for the last time and before the first application exits the terminal device for the next time.
For example, if the first content is: "ABCDEFG", then the first content saved to the first storage space is also "ABCDEFG".
Optionally, after the first content is saved in the first storage space, a data identifier may be added to the first storage space, where the data identifier is used to indicate that the first content is in the first storage space.
Correspondingly, if the first content does not exist in the clipboard storage space at this time, a data identifier for indicating that the first storage space is empty is added to the first storage space.
For example, the data added to the first storage space indicating that the first storage space is empty is identified as "null", and the data added to the first storage space indicating that the first content is stored in the first storage space is identified as "full".
In particular, with respect to the above-described embodiments,
if the detection is after the first application is monitored to enter for the last time, and a copy event or a cut event is triggered before the first application exits for the last time, the first content in the clipboard storage space is saved into the first storage space.
Once the storage event or the cutting event is triggered, the first content is necessarily stored in the clipboard storage space, so that when the replication event or the cutting event is triggered is monitored, the first content in the clipboard storage space at the moment only needs to be stored in the first storage space.
For example, if the first content is: "1234567", then the first content stored in the first storage space is also "1234567".
If the copy event or the cut event is not triggered after the last monitoring of the first application entry event and before the first application exit event this time, it is considered that no operation is required on the clipboard storage space at this time.
In another optional embodiment, when the first content in the clipboard storage space is saved in the first storage space, a data identifier may be further added to the first storage space, where the data identifier is used to indicate that the first content is in the first storage space.
And if the first content does not exist in the clipboard storage space at the moment, adding a data identifier for indicating that the first storage space is empty to the first storage space.
For example, the data added to the first storage space indicating that the first storage space is empty is identified as "null", and the data added to the first storage space indicating that the first content is stored in the first storage space is identified as "full".
In another alternative embodiment, in practice, not all content in a first application can be copied to a second application, for example, content in a certain first application includes: enterprise technical data, enterprise product data; the enterprise technical data cannot be copied to the second application as the technical secret, and the enterprise product data is information to be distributed to the public and can be copied to the second application, so that the content in the first application is selectively prevented from being copied to the second application. At this time, when an exit event of the first application is monitored, storing the first content in the clipboard storage space into the first storage space corresponding to the first application, and when the clipboard storage space is emptied, when the exit event of the first application is monitored, acquiring security configuration information corresponding to the first content;
and if the security configuration information indicates that the first content cannot be acquired by the second application, storing the first content in the clipboard storage space into the first storage space corresponding to the first application, and clearing the clipboard storage space.
In a specific implementation, the security configuration corresponding to the first content is set by the application at the time of installation. For first content which cannot be copied to a second application, the corresponding security configuration information is used for indicating that the first content cannot be acquired by the second application; for the first content which can be copied to the second application, the corresponding security configuration information is used for indicating that the first content can be acquired by the second application.
Therefore, when a quit event of the first application is detected, the security configuration information corresponding to the first content is acquired first, and when the security configuration information corresponding to the first content indicates that the first content cannot be acquired by the second application, the first content in the clipboard storage space is stored in the first storage space corresponding to the first application, and the clipboard storage space is emptied. If the security configuration information corresponding to the first content indicates that the first content can be acquired by the second application, the clipboard is kept unchanged.
S103: when an entry event of a first application is monitored, first content in a first storage space corresponding to the first application is saved in a clipboard storage space.
Here, the monitored entry event of the first application is an entry event after the last monitoring of the exit event of the first application. If the first application is installed and the first application is monitored for the entering event, the first content in the first storage space does not need to be saved in the clipboard storage space because the first content does not exist in the first storage space.
When the method is implemented, the first content in the first storage space corresponding to the first application may be saved in the clipboard storage space in the following manner.
When the terminal device monitors an entry event of the first application, whether the first content is stored in the current first storage space is detected. If the first content is stored in the first storage space at this time, the first content is stored in the clipboard storage space.
For example, if it is detected that the first content "keldhxwisjds" is stored in the first storage space, the first content "keldhxwisjds" is copied to the clipboard storage space.
And if the first content is not stored in the current first storage space, namely no content is stored in the current first storage space, the clipboard is not processed.
Here, it should be noted that, when detecting whether the first content is currently stored in the first storage space, whether the first content is currently stored in the first storage space may be detected by accessing the first storage space to detect whether the first content is currently stored in the first storage space. The method of detecting the data identifier of the first storage space to indicate that the first storage space has the first content or indicate that the first storage space is empty may also be adopted to detect whether the first content is currently stored in the first storage space.
In the content copying method provided by the embodiment of the invention, by monitoring an entry event and an exit event of a first application, when the exit event of the first application is monitored, first content in a clipboard storage space is stored in a first storage space corresponding to the first application, and the clipboard storage space is emptied, so that the content in the first application cannot be copied into a second application; when the first application entering event is monitored, the first content in the first storage space corresponding to the first application is stored in the clipboard storage space, so that the user can realize the copying of the content in the same first application, the content in the first application is prevented from being copied into the second application, and other control events triggered by the user pressing the device screen for a long time cannot be influenced.
Fig. 2 is a schematic flow chart of another content copying method according to a second embodiment of the present invention. On the basis of the above embodiment, in the content copying method provided by the embodiment of the present invention:
s201: before saving the first content in the first storage space corresponding to the first application to the clipboard storage space, the method further includes: and saving the second content of the second application in the clipboard storage space to a second storage space corresponding to the second application.
In a specific implementation, the second storage space is a storage space provided by an operating system of the terminal device for an application other than the first application. The second storage space is used for temporarily storing second content copied or cut by the user from the second application.
Here, it is to be noted that, in one terminal apparatus, a plurality of content-protected applications and a plurality of content-unprotected applications may be installed; optionally, each content-protected application is uniquely associated with a first storage space; the plurality of content unprotected applications have a second storage space in common.
And storing the second content of the second application in the clipboard storage space into a second storage space corresponding to the second application, wherein the second content can be executed when the second application exits or when an entry event of the first application is monitored.
When the terminal device monitors the entry event of the first application, any one of the following methods may be adopted to store the second content of the second application in the clipboard storage space into the second storage space corresponding to the second application.
I, detecting whether second content exists in the clipboard storage space by accessing the clipboard storage space; or,
and II, detecting whether the second content exists in the storage space of the clipboard by detecting whether a copy event or a cut event is triggered after the first application is monitored to exit for the last time and before the first application enters for the next time.
Specifically, in the above embodiment (i), after the exit event of the content-protected first application is monitored, the first content in the clipboard storage space is stored in the first storage space corresponding to the first application, and the clipboard is emptied, so that after the first application exits and before the next entry of the first application, if the memory exists in the clipboard storage space, the content of the second application whose content is not protected is stored. And if the second content exists in the clipboard storage space at the moment, saving the second content in the clipboard storage space to the second storage space.
For example, if the second content is: "ABCDEFG", then the second content saved to the second storage space is also "ABCDEFG".
Optionally, after the second content in the clipboard storage space is saved in the second storage space, a data identifier may be added to the second storage space, where the data identifier is used to indicate that the second storage space has the second content.
Correspondingly, if the second content does not exist in the clipboard storage space at this time, a data identifier for indicating that the second storage space is empty is added to the second storage space.
For example, the data added to the second storage space indicating that the second storage space is empty is identified as "null", and the data added to the second storage space indicating that the second content is stored in the second storage space is identified as "full".
Specifically, in the above embodiment (II),
(1) if a copy event or a cut event is triggered before the first application enters this time, the second content in the clipboard storage space is saved to the second storage space.
Since the second content is inevitably stored in the clipboard storage space once the storage event or the clipping event is triggered when the user uses the second application, when the copy event or the clipping event is triggered, it is only necessary to store the second content in the clipboard storage space into the second storage space.
For example, if the second content is: "1234567", then the second content stored in the second storage space is also "1234567".
If a copy event or a cut event is not triggered before the last monitoring of the first application entry, then it is assumed that no operations are required on clipboard storage.
Or,
(2) and if the condition that the copying event or the cutting event is triggered before the first application is monitored to enter is detected, storing the second content in the clipboard storage space into the second storage space, and adding two data identifications for the second storage space, wherein the data identifications are used for indicating that the first content exists in the second storage space.
And if the second content does not exist in the clipboard storage space at the moment, adding a data identifier for indicating that the second storage space is empty to the second storage space.
For example, the data added to the second storage space indicating that the second storage space is empty is identified as "null", and the data added to the second storage space indicating that the second content is stored in the second storage space is identified as "full".
S202: when the exit event of the first application is monitored, the first content in the clipboard storage space is stored in the first storage space corresponding to the first application, and after the clipboard storage space is emptied, the second content in the second storage space corresponding to the second application is stored in the clipboard storage space.
In a specific implementation, the following manner may be adopted to store the second content in the second storage space corresponding to the second application into the clipboard storage space.
And when the terminal equipment monitors the exit event of the first application, detecting whether the second content is stored in the current second storage space. And if the second content is stored in the second storage space at the moment, storing the second content into the clipboard storage space.
For example, if it is detected that the second content "keldhxwisjds" is stored in the second storage space, the second content "keldhxwisjds" is copied to the clipboard storage space.
And if the second content is not stored in the current second storage space, namely no content is stored in the current second storage space, the clipboard is not processed.
Here, it should be noted that, when detecting whether the second content is currently stored in the second storage space, whether the second content is currently stored in the second storage space may be detected by accessing the second storage space to detect whether the first content is currently stored in the second storage space. The method of detecting the data identifier of the second storage space to indicate that the second storage space has the second content or indicate that the second storage space is empty may also be adopted to detect whether the second content is currently stored in the second storage space.
By adopting the embodiment, after the first application is monitored to enter, the second content in the clipboard storage space is stored in the second storage space corresponding to the second application; and when the exit event of the first application is monitored, storing second content in a second storage space corresponding to the second application into the clipboard storage space, so that the clipboard storage space can be restored to a state before the first application is opened. When the content in the second application a is copied to the second application B, if the user opens the first application before pasting the content to the application B, when the first application is closed, the clipboard storage space is also restored to the state before opening the first application, so that the content to be copied to the second application B does not need to be copied or cut again from the second application a, and the pasting is directly performed in the second application B, thereby improving the user's perception.
In addition, in another optional embodiment, in the step S201, after the second content of the second application in the clipboard storage space is stored in the second storage space corresponding to the second application, the clipboard storage space may be emptied, so that the second content of the second application cannot be copied into the first application, and the first application and the second application are completely isolated, that is, the content in the first application cannot be copied into the second application, and the content in the second application cannot be copied into the first application.
In another embodiment of the present invention, in order to prevent a second application from accessing a first storage space corresponding to a first application to obtain a first content after saving the first content in the first storage space, the method further includes, after saving the first content in the clipboard storage space in the first storage space corresponding to the first application:
encrypting the first content in the first storage space;
saving the first content in the first storage space corresponding to the first application to the clipboard storage space, including:
and decrypting the first content in the first storage space and storing the first content in the clipboard storage space.
In this way, it can be ensured that only the first application can obtain the first content in the first storage space. And because the first content is encrypted, even if a second application accesses the first storage space and obtains the encrypted first content from the first storage space, the encrypted first content cannot be decrypted, and thus the first content cannot be obtained.
In another alternative embodiment, when installing an application, an application protection list may be configured in a configuration file of the application, and when recognizing that an application of the same vendor is installed, an identification of the application may be added to the application protection list. Applications that are in the same application protection list may allow copying of content to each other.
For example, if a third application is also installed in the terminal device. When the first application and the third application belong to the same enterprise manufacturer, the two application identifications can be added to the same application protection list, and the first application and the third application are allowed to copy contents mutually.
When the third application does not belong to the same vendor, the first application and the third application are not added to the same application protection list, and mutual content copying between the first application and the third application is not allowed.
In the content replication method provided in the embodiment of the present invention, after monitoring an entry event of a first application, the method further includes: and detecting whether the first application and the third application are in the same application protection list, and if the first application and the third application are in the same application protection list, storing the contents stored in the third storage space and the first storage space for a later time into the clipboard storage space.
In one embodiment, the first application and the third application each have their own storage space, and when an exit event of the first application is detected, the content in the clipboard is copied to the first storage space, and when an exit event of the third application is detected, the content in the clipboard is copied to the third storage space. The first storage space and the third storage space are isolated from each other. In order to realize that the contents between the two applications can be copied with each other, the contents stored in the two storage spaces can be restored to the clipboard.
In the alternative, it is possible to,
and if the first application and the third application are in the same application protection list, the third storage space corresponding to the third application and the first storage space corresponding to the first application are the same storage space. By the embodiment, the content of the application belonging to the same manufacturer can be copied mutually.
Referring to fig. 3, a third embodiment of the present invention further provides a content replication method, where the method includes:
s301: an entry event and an exit event of the first application are monitored.
S302: and when the entry event of the first application is monitored, storing the content A corresponding to the second application in the clipboard storage space into the space A.
S303: the shear plate is emptied. Step 303 is an optional operation, and contents copied or cut by other applications may be brought into the first application through the clipboard without clearing the clipboard. If step S303 is not performed, S304 is performed after S302 is performed.
S304: in the running process of the first application, a user executes a cutting operation or a copying operation, and the content B to be copied or cut is stored in the clipboard storage space.
S305: and when the exit event of the first application is monitored, storing the corresponding content B in the first application in the clipboard storage space into the space B.
S306: the shear plate is emptied.
S307: and saving the content A corresponding to the second application saved in the space A into the clipboard storage space to restore the state of the clipboard storage space before S302.
By the method, the first application and the second application can be divided, so that the first application can be isolated from the second application, the content of the second application cannot be copied into the first application, and the content of the first application cannot be copied into the second application.
In addition, in another optional embodiment, the content replication method provided by the present invention may further include:
monitoring an exit event of the first application;
when the exit event of the first application is monitored, the first content in the clipboard storage space is stored in the first storage space corresponding to the first application, and the clipboard storage space is emptied.
And when the entering event of the first application is monitored, the second content in the storage space of the clipboard is not saved in the second storage space, and the clipboard is not emptied.
Or, when the entry event of the first application is monitored, the clipboard will not be emptied although the second content in the clipboard storage space will be saved to the second storage space.
In this way, copying of content in the second application into the first application may be achieved.
Based on the same inventive concept, the embodiment of the present invention further provides a content copying method apparatus corresponding to the content copying method, and as the principle of the apparatus in the embodiment of the present invention for solving the problem is similar to the content copying method described above in the embodiment of the present invention, the implementation of the apparatus may refer to the implementation of the method, and repeated details are not described again.
As shown in fig. 4, a content copying apparatus provided in the fourth embodiment of the present invention is applied to a terminal device, and includes:
a monitoring module 41, configured to monitor an entry event and an exit event of the first application;
