The mobile phone clipboard function has been widely used as a basic function, and a user can arbitrarily copy/clip his/her desired contents in a certain application and then paste the contents to a desired place in other applications. However, the clipboard often contains user sensitive data, such as a bank card number, a password, a verification code, an identification card number, a telephone, an address, and the like, which are easy to risk being illegally accessed or revealed by an application, and even being excessively utilized to achieve the purpose of advertisement pushing. The existing clipboard protection scheme cannot effectively protect the privacy of a user.

In order to solve the technical problem that user sensitive data in a clipboard is easy to be illegally accessed or leaked by an application, the embodiment of the application provides a clipboard access control method, which is applied to electronic equipment and used for avoiding the situation that the data in the clipboard is illegally accessed or leaked by some applications, and improving the safety of user data. Specifically, when the clipboard replication information is utilized, the embodiment of the application can determine the associated application corresponding to the replication information, when the application sends a read request for the replication information, determine whether the application is the associated application corresponding to the replication information, and if the application is determined to be the associated application corresponding to the replication information, grant the read request for the replication information to the application. Otherwise, if the application is not the associated application corresponding to the copy information, rejecting the read request of the application to the copy information.

It is understood that the electronic device in the present application may be a mobile phone, tablet, desktop, laptop, handheld, notebook, ultra-mobile personal computer (UMPC), netbook, as well as a cellular phone, personal digital assistant (personal digital assistant, PDA), artificial intelligence (artificial intelligence, AI) device, wearable device, vehicle-mounted device, smart home device, and/or smart city device. The embodiment of the application does not particularly limit the specific form of the electronic device. The method for managing and controlling access to the clipboard provided by the application is described in detail below by taking the application of the method provided by the application to a mobile phone as an example in combination with the accompanying drawings.

Fig. 1 is a schematic diagram of a method for managing access to a clipboard, where the method is applied to an electronic device, and the electronic device includes a first application, a second application, and a system clipboard. As shown in fig. 1, the method may include:

the first application determines 101 the copy information selected by the user.

The first application determines copy information selected by a User after detecting a copy operation of the User on a User Interface (UI).

In some embodiments of the present application, if the user-selected copy information includes a uniform resource identifier (Uniform Resource Identifier, URI), the first application may create a Content Provider (Content Provider) for storing the copy information.

102, the first application invokes the system clipboard.

After determining the copy information selected by the user, the first application may send a copy operation command to the system clipboard service to invoke the system clipboard to write the copy information.

And 103, writing the copy information by the system clipboard, and storing the copy information.

104, the system cut board acquires the context information corresponding to the copy information, analyzes the context information and determines the target pasting application corresponding to the copy information.

In the embodiment of the application, the target pasting application is an application which authorizes or allows pasting of the copy information and has the authority to read the copy information. The target paste application may include one or more applications. The context information corresponding to the copy information generally includes information related to the copy information. For example, as shown in fig. 2, the information received by the electronic device is schematically shown, and some verification code notifications include an application corresponding to the verification code, that is, a target pasting application corresponding to the verification code. By analyzing the verification code notification, the application in the verification code notification can be determined to be the target paste application corresponding to the copy information (e.g., verification code), such as the XX video in fig. 2 can be determined to be the target paste application corresponding to the copy information (e.g., verification code "308859").

For another example, as shown in fig. 3, another information diagram received by the electronic device is shown, and some order notifications include an order number and also include a service provider corresponding to the order. By analyzing the order notification, an application that the service provider corresponding to the order provides service for the user can be determined as a target pasting application corresponding to the copy information (e.g., order number). As shown in FIG. 3, the service provider corresponding to the order in an order notification is XX buying, the application served by the service provider is application A, and application A can be determined to be the target pasting application corresponding to the copy information (e.g., order number "123456").

In some embodiments of the present application, the system clipboard obtaining the context information corresponding to the copy information may include: and acquiring the screen content currently corresponding to the first application, identifying the screen content, and acquiring the context information corresponding to the copy information. A system screen service may be invoked to obtain the current screen content of the electronic device.

In some embodiments, the contextual information may be analyzed based on a particular keyword match. For example, the specific keyword may include an application name, after the user copies the verification code of a piece of information in the short message application, the user performs application name matching on the information, and determines the application name included in the short message. The application corresponding to the application name may be determined as the target pasting application, or the application corresponding to the application name may be determined as the target pasting application after the application corresponding to the application name is determined to be installed on the electronic device. For example, an application list installed on the electronic device may be acquired, and after the acquired application list is determined to include an application corresponding to the application name, the application is determined to be a target application. In addition, the semantic analysis can be performed on the context information based on algorithms such as machine learning, deep learning and the like, so as to determine the target pasting application. Further, the target paste application may also be determined by recognition of specific characters (e.g., brackets "[ MEANS FOR ] etc.) in combination with semantic parsing of the context information. For example, an application in a particular character may be determined as a target paste application.

The above method of analyzing the context information is merely illustrative, not limiting, and other ways of analyzing the context information may be used.

In some embodiments of the present application, if a plurality of applications are determined after the context information is analyzed, one or more target pasting applications may be determined among the plurality of applications based on a selection of a user, or the plurality of applications may be all determined as target pasting applications.

Determining one or more target paste applications among the plurality of applications based on the user's selection may include: the system clipboard sends the determined multiple applications to the first application; the first application presents the plurality of applications to a user; the first application determines a target paste application among the plurality of applications based on the user's selection and sends the determined target paste application to the system clipboard. When the system clipboard transmits the determined plurality of applications to the first application, the algorithm analysis result may be transmitted to the first application. The plurality of applications may be all applications calculated by the system clipboard, and the determining of the partial applications among the plurality of applications may be based on a preset selection rule. The preset selection rule may include selecting an application matching probability that has a matching probability greater than a preset threshold value among all applications to represent a matching degree of the application of the context information corresponding to the copy information. The higher the probability of matching, the higher the degree of matching of the application to the copy information. Or may be selected from a number of applications (e.g., selecting the application with the probability value of the first five) among all applications. Or it may also be to select all applications installed by the electronic device or select some applications installed by the electronic device among the plurality of applications after comparison with the local installed application list, and so on.

The first application may present all the multiple applications sent by the system clipboard, or may present part of the applications in the multiple applications according to a preset selection rule (e.g., present an application with a relatively high probability, present an application in which all or part of the applications are installed, which is determined by comparing the application with a local installed application list, etc.). After the first application receives the plurality of applications sent by the system clipboard, the plurality of applications can be directly displayed without presenting the plurality of applications. The application search box is used for assisting a user in determining a target pasting application corresponding to the copy information. The application search box can facilitate the user to search the application so as to improve the efficiency of determining the target pasting application.

It may be appreciated that, if the system clipboard determines a plurality of applications based on the analysis of the context information, the system clipboard may not send the determined application information of the plurality of applications to the first application, and may directly request the first application to determine the target paste application. After the first application receives the request sent by the system cut-off board, an application selection button can be displayed on an interface corresponding to the first application, and the application selection button is used for assisting a user in determining a target pasting application. And determining a target pasting application corresponding to the copy information based on the selection of the application selection button by the user. The application selection button may be displayed at a preset position corresponding to the copy information. For example, as shown in fig. 4, an application selection button of "copy to" is displayed next to the copy information (456456). When the user clicks the "copy to" application selection button, an application list for displaying applications installed on the electronic device may be popped up for the user to select a target paste application, as shown in fig. 5. The user may select from a list of applications that pop up to determine one or more target paste applications. It will be appreciated that the pop-up application list may display applications installed on the electronic device in a preset display rule, such as displaying applications installed on the electronic device according to the frequency with which the user uses the application. As shown in fig. 5, the pop-up application list may further include an application search box to facilitate the user to input an application name for searching applications, and it may be appreciated that the application search box may also be popped up separately.

In some embodiments of the present application, after determining the target pasting application corresponding to the copy information, a prompt for the target pasting application may also be generated and displayed according to a preset prompt rule. For example, after determining that the target pasting application corresponding to the copy information is application C, a prompt as shown in fig. 6 is generated and displayed, and the user is prompted to allow only application C to access and acquire the copy content (456456). By displaying the prompt for the target pasting application, a user can intuitively determine the target pasting application corresponding to the copy information.

The second application sends 105 a read request for the copy information to the system clipboard.

The system clipboard determines 106 whether the second application is a target paste application.

In some embodiments of the present application, after determining the target paste application corresponding to the copy information, the method further includes: and associating the copy information with the target pasting application to obtain association information. And if a read request of the second application to the copy information is received, the system cut-off board determines whether the second application is the target pasting application according to the association relation.

And if the second application is not the target pasting application, the system cut board refuses the reading request of the second application and does not send the copy information to the second application. After the system clipboard determines not to send the copy information to the second application, a rejection prompt may be popped up to the user. The rejection prompt is used to prompt the user that the second application has been rejected. Wherein the rejection prompt may include the second application information and the behavior of the second information being rejected (attempt to read the clipboard behavior). The rejection prompt may also include a rejection reason (e.g., the copy information allows only the target paste application to read, does not allow other applications to read, etc.). As shown in fig. 7, the rejection prompt may be displayed on the display interface of the electronic device in a box-flicking mode, where the rejection prompt includes a second application name (XXX video), and a rejection action (attempting to obtain the copy content of this time) corresponding to the second application.

In some embodiments of the present application, if the second application is not the target pasting application, the system clipboard may display an inquiry box for inquiring whether the user allows the second application to read the copy information, and determining whether to send the copy information to the second application based on a selection of the user. It will be appreciated that if the second application is not the target paste application, the system clipboard may display a prompt box that may include content related to reject prompts and query boxes. On the prompt box, the user can learn about the rejected second application and can choose whether to allow the second application to read the copy information. In some embodiments of the present application, after determining the copy information selected by the user, the first application determines a sensitivity level of the copy information, and if the second application is not the target paste application and the sensitivity level of the copy information is greater than a preset sensitivity threshold, the system clipboard may display an inquiry box or a rejection prompt. And only when the sensitivity level of the copied information is larger than a preset sensitivity threshold, the behavior of reading the copied information for the application without the reading authority is generated to reject the prompt or inquiry bullet frame, so that the occurrence frequency of the reject prompt or inquiry bullet frame can be reduced.

If the second application is the target pasting application, the system clipboard executes 107 to send the copy information to the second application. In some embodiments of the present application, after the system clipboard sends the replication information to the second application, the system clipboard deletes the saved replication information, and if there is associated information corresponding to the replication information, the system clipboard may delete the associated information corresponding to the replication information. The system clipboard sends the copy information to the second application, and a use prompt corresponding to the second application can be generated to prompt the user that the second application has acquired the copy content, so that the user perceives the process that the second application accesses the system clipboard, and the safety of the data of the system clipboard is improved.

In some embodiments of the present application, after 103 in fig. 1 is executed, if the target paste application cannot be determined according to the analysis of the context information, or if the determined target paste application is not installed by the electronic device, an application selection button may be displayed on an interface corresponding to the first application, and the description of the application selection button may be referred to the above description and will not be repeated herein.

According to the embodiment, the system cut-off board determines the target pasting application corresponding to the copy information in the system cut-off board based on the context analysis, and associates the copy information with the corresponding target pasting application, so that only the target pasting application associated with the copy information is allowed to access and read the copy information in the system cut-off board, the condition that data in the system cut-off board is illegally accessed or leaked by some applications can be avoided, and the safety of copying and pasting the information by the system cut-off board is improved.

In some embodiments of the present application, as shown in fig. 8, after the system clipboard writes the copy information and saves the copy information, the method further includes:

the system clipboard determines 201 the sensitivity level of the replicated information.

Sensitivity levels corresponding to different information may be set, with different information types corresponding to the same or different sensitivity levels. For example, two sensitivity levels (sensitive and insensitive) may be set, or three sensitivity levels and more may be set, and the sensitivity levels may be set according to actual conditions, without any limitation. For example, sensitivity levels may be sequentially increased by 1-N levels (e.g., non-sensitive, generally sensitive, more sensitive, highly sensitive, etc.).

In some embodiments of the present application, the system clipboard may invoke a system data management service to determine the sensitivity level of the replicated information. The system data management service may determine a sensitivity level of the copy information according to a keyword matching rule, for example, by presetting keywords, matching the copy information with preset keywords, and determining the sensitivity level of the copy information, where each keyword may correspond to one sensitivity level. The system data management service may also determine the sensitivity level of the replicated information based on a preset recognition model (e.g., machine learning or deep learning model). The method for determining the sensitivity level of the copy information by the system data management service may be selected according to the actual situation, and the above examples are only illustrative, and not limiting, and the system data management service may determine the sensitivity level of the copy information based on other methods.

202, the system clipboard determines whether the sensitivity level of the copied information is greater than a preset sensitivity threshold.

The sensitivity threshold may be preset according to the sensitivity level. For example, when the sensitivity level is 3 or more, the sensitivity level 2 may be set as the preset sensitivity threshold, and if the sensitivity level of a piece of copy information is greater than the sensitivity level 2, it is determined that the sensitivity level of the copy information is greater than the preset sensitivity threshold.

If the sensitivity level of the copy information is greater than the preset sensitivity threshold, executing 104 and subsequent processes in fig. 1; if the sensitivity level of the duplicated information is less than or equal to the preset sensitivity threshold, it is determined that the duplicated information is not required to be safely managed, and as a result, the steps 104 and the subsequent steps 104 in fig. 1 are not continuously executed. When the sensitivity level of the copy information is smaller than or equal to the preset sensitivity threshold, if a read request of the second application for the copy information is received, the copy information may be directly sent to the second application, or after the system clipboard may prompt and solicit comments from the user, it is determined whether to send the copy information to the second application according to whether the user is authorized or not. For example, as shown in fig. 9, the system clipboard may prompt and solicit comments from the user in a box-like manner. As shown in fig. 9, a determination button (consent) and a rejection button (rejection) may be included in the bullet frame, and the copy information is transmitted to the second application when the user selects the determination button; when the user selects the reject button, rejecting the read request of the second application, and generating a corresponding reject prompt.

It is to be understood that the execution time nodes 201-202 in fig. 8 are merely illustrative. The execution time nodes 201-202 in fig. 8 may be set according to practical situations, and are not limited in any way herein. For example, 201-202 in FIG. 8 may be performed after 105 in FIG. 1, and if the sensitivity level of the copy information is greater than the preset sensitivity threshold, 106 in FIG. 1 is performed. If the sensitivity level of the duplicate information is less than or equal to the preset sensitivity threshold, it is determined that the duplicate information does not need to be securely managed, and the process is ended, and the execution of 106 in fig. 1 is not continued, so that the duplicate information can be directly sent to the second application. Alternatively, the system clipboard may determine whether to send the copy information to the second application based on whether the user is authorized or not after the suggestion is solicited from the user. In addition, 201-202 in fig. 8 may be performed at any node before or after 102-105 in fig. 1, such as 201-202 in fig. 8 after 101 in fig. 1, 201-202 in fig. 8 after 105 in fig. 1, and 201-202 in fig. 8 after 106 in fig. 1 determines no.

It will be appreciated that 201 and 202 in fig. 8 may also be separately executed at different time nodes, and may be similar to the above description of executing time nodes, for example, executing 201 after 103 in fig. 1 and executing after 105 or 106 in fig. 1 if the determination result is no, which is not limited in this embodiment of the present application, but is to ensure that 201 is executed first.
