Referring to FIG. 2, in a first embodiment of the method for controlling screen file sharing, the method for controlling screen file sharing includes:

Step S11: Receive a file save request, save the file associated with the file save request to local storage, generate corresponding attribute information, and establish an association relationship between the file and the attribute information.

The terminal receives the file save request, wherein the method for triggering the file save request is more, and the terminal may automatically trigger at the set time point, or the user manually triggers, for example, the user clicks the terminal virtual button “Save” button to trigger the file save request. When the terminal receives the file save request, the terminal acquires the file associated with the file save request, and the terminal saves the file to the local storage, and generates attribute information of the file, including: file type, file size, file creation time, file modification. The time, the file access time, the file storage path, and the like, the terminal establishes an association relationship between the file and the corresponding attribute information, where the relationship between the file and the corresponding attribute information may be a one-to-one mapping relationship or a table. form.

Step S12: Receive a file sharing request, obtain the to-be-shared file in the file sharing instruction, and obtain the attribute information according to the association relationship.

The terminal receives the file sharing request, where the file sharing request refers to a request corresponding to the file selection performed before the user sends the file to the public platform or the file is sent to the receiving user end, and the terminal does not perform the file sending operation, wherein the file is triggered. There are many forms of sharing requests, which may be that the terminal automatically triggers at the set time, or when the user operates based on the file, manually triggers the file file type identification instruction, and the file sharing request needs to be supplemented, which is before the file sending instruction. In one step, it can be understood that the user selects to send a file request. For example, the user clicks the virtual button of “add sharing information” on the terminal display interface to trigger a file sharing request, the terminal receives the file sharing request, and the terminal acquires the file in the sharing request. The terminal acquires attribute information corresponding to the file according to the association relationship. Determine if the file is a screen capture file.

In step S13, the attribute information is compared with the preset screen capture determination rule, and it is determined whether the file to be shared is a screen capture file.

The terminal compares the attribute information with the preset screen capture determination rule to determine whether the file to be shared is a screen capture file, wherein the preset screen capture determination rule refers to a determination rule set in advance according to the standard information of the screen capture file, for example, storage of a standard screen capture file. The path includes storage path information such as screenshot. If the file attribute information includes storage path information such as screenshot, the terminal determines that the file to be shared is a screen capture file.

Optionally, the terminal determines, according to the attribute information, whether the file is a different implementation manner of the screen capture file. In this embodiment, three implementation forms are specifically provided:

Method 1, according to the file storage path in the attribute information, including:

The terminal compares the file storage path in the attribute information with a preset path in the preset screen capture determination rule;

If the file storage path in the attribute information matches the preset path in the preset screenshot determination rule, it is determined that the file to be shared is a screen capture file.

Specifically, in the embodiment, the file is determined to be a screen capture file according to the storage path information of the file, that is, the terminal stores the file storage path in the attribute information and a preset path in the preset screen capture determination rule (the preset path is in advance The standard path information of the set screen capture file is compared; if the file storage path in the attribute information matches the preset path in the preset screen capture determination rule, it is determined that the file to be shared is a screen capture file, in this embodiment Under the condition that the user does not change the storage path, the screen capture file can be accurately identified to ensure the accuracy of the screen capture file identification.

Method 2, according to the file size information in the attribute information, including:

Comparing the file size data in the attribute information with the preset size in the preset screen capture determination rule;

If the file size data in the attribute information matches the preset size in the preset screen capture determination rule, it is determined that the file to be shared is a screen capture file.

In the embodiment, the file size information in the attribute information is specifically described, that is, the file size data in the attribute information and the preset size in the preset screen capture determination rule (preset size: is the standard size of the screen capture file, The preset size of the normal screen capture is equal to the size of the terminal display screen, the width of the screenshot file of the long screen is the same as the width of the terminal display screen, and the preset size of the free screen capture is smaller than the size of the terminal display screen; if the file in the attribute information The size data is matched with the preset size in the preset screen capture determination rule, and the file to be shared is determined to be a screen capture file. In the embodiment, the screen capture file can be accurately identified according to the screen size and the file size of the terminal. The screen capture file is accurately identified when the user takes a normal screen shot.

Mode 3, according to the time information in the attribute information, including:

In the embodiment, the time information in the attribute information is specifically described, that is, the time when the terminal acquires the generation time in the attribute information and the current display time of the terminal display screen, and the time interval between the generation time and the current display time of the terminal display screen is obtained; The generation time refers to the generation time of the screen capture file, that is, the time information displayed on the screen capture file can be identified, and the generation time of the screen capture file is obtained, for example, the user screen captures the terminal, and the terminal display time included in the screen capture file is the generation of the screen capture file. Time, the terminal sets the time interval in the attribute information and the preset time in the preset screen capture determination rule (preset time: is the interval between the preset file generation time and the display time on the terminal, and can be set to 1 second according to the specific situation. If the time interval matches the preset time in the preset screen capture determination rule, the file to be shared is determined to be a screen capture file. In this embodiment, the terminal generates the screen capture file and the current display screen of the terminal. Display the difference in time, determine whether the file is a screen capture file, and increase the screen capture file. The accuracy of the identification.

It should be noted that the implementation manner of determining the screen capture file according to the attribute information is specifically given in this embodiment, and each mode can be combined to accurately identify the screen capture file. For example, the terminal first reduces the current time of the application in the foreground. The time to add the database image is less than 1 second; again, the image size is not larger than the screen size; finally, the image path keyword includes: ""screen Cap", "screenshot" or "screenshot" keywords; the specific implementation of the combination is not detailed.

Step S14: If the file to be shared is a screen capture file, output a screen capture file sharing risk prompt.

If the terminal determines that the file to be shared is a screen capture file, the terminal displays an output screen capture file sharing risk prompt. For example, the terminal determines that the file shared by the user is a screen capture file, and the terminal displays a floating frame, and displays the file as a screen capture file in the floating box. Share the risk of whether to continue sharing, to remind users of the risk of screen file sharing.

In this embodiment, the files to be saved in the present application are compared according to the set rules, and the saved file is accurately identified as a screen capture file. When it is determined that the terminal save file is a screen capture file, the screenshot is sent according to the screen capture file sent by the user. The file displays information detection, which realizes sensitive information monitoring of screen capture files in the personal field and reduces the leakage of sensitive personal information.

Referring to FIG. 3, based on the first embodiment of the present application, the present embodiment of the method for controlling screen file sharing in the present application is further proposed. This embodiment is a refinement of step S13 in the first embodiment.

Specifically, the following steps are specifically described in the embodiment that the storage of the file to be shared is a screen capture file according to the preset screen capture determination rule:

In step S131, the attribute information is compared with a preset screen capture determination rule, where the attribute information includes: a storage path and/or size data.

The terminal includes attribute information (wherein the attribute information includes: a storage path and/or a size data, and further, the attribute information further includes a file type, a file size, a file creation time, a file modification time, a file access time, etc., The description will not be repeated here). The preset screen capture determination rule is a determination rule preset according to the standard attribute information of the screen capture file, for example, the storage path in the preset screen capture determination rule. The decision rule is that the path standard identifier of the screen capture file, or the path keyword is also included: "screenshot", "screen_shot", "screen-shot", "screen Shot", "screencapture", "screen_capture", "screen-capture", "screen Capture", "screencap", "screen_cap", "screen-cap", "screen Cap", "screenshot" or "screenshot" means that the terminal determines the rule according to the storage path in the preset screen capture decision rule.

In step S132, if the storage identifier corresponding to the storage path matches the path standard identifier in the preset screen capture determination rule and/or the size data matches the screen size in the preset screen capture determination rule, it is determined that the file to be shared is a screen capture file.

If the terminal determines that the storage identifier corresponding to the storage path matches the path standard identifier in the preset screen capture determination rule and/or the size data matches the screen size in the preset screen capture determination rule, for example, if the path of the screen capture file includes: “screen capture” The terminal compares the "screen capture" with the path standard identifier of the screen capture file in the preset screen capture determination rule. If the path standard identifier of the screen capture file in the preset screen capture determination rule includes "screen capture", the storage identifier corresponding to the storage path and The preset screen capture determination rule is matched; and/or the picture size in the size data attribute information is compared with the screen size of the terminal in the preset screen capture determination rule, if the picture size is the same as the screen size, that is, the size data and the preset screen capture determination rule If the screen size in the match is matched, it is determined that the file to be shared is a screen capture file.

In the embodiment, the terminal specifically determines, according to the attribute information and the preset screen capture determination rule, that the file to be shared is a screen capture file, compared with the existing screen capture monitoring, the prior art determines when the screen capture instruction is triggered. It is a screen capture file and saved. In the latter stage, the screen capture file cannot be identified. In this implementation, the accuracy of the screen capture file identification is guaranteed.

Referring to FIG. 4, based on the first embodiment of the method for controlling the screen file sharing of the present application, a second embodiment of the present application is further provided. In the embodiment, the step of identifying the display information of the screen capture file includes:

Step S21: Receive an identification instruction triggered by the screen capture file, and identify the information category of the display information and the display information included in the screen capture file.

The terminal receives the identification instruction triggered by the screen capture file, and identifies the information category of the display information and the display information contained in the screen capture file. For example, the terminal determines to identify the screen capture file, and the screen capture file may include text, symbols or other identification information, and the terminal may include Determines whether the text, symbol, or other identifying information contained in the screen capture file belongs to the text category or to the image category.

Step S22: Acquire pre-set sensitive information of the information category in the preset sensitive information database, and compare the display information with the preset sensitive information.

The terminal acquires the preset sensitive information database (the preset sensitive information database includes sensitive text information, sensitive image identification information, etc., for example, the sensitive information can be set to the user's personal identification number, home address, etc.) The sensitive information compares the display information with the preset sensitive information, that is, if the display information included in the screen capture file is text information, the terminal acquires the preset sensitive text in the preset sensitive information database, and the terminal includes the text in the screen capture file. The information is compared with preset sensitive text in a preset sensitive information base.

In step S23, if the display information matches the preset sensitive information, it is determined that the screen capture file contains sensitive information, and the screen capture file is added with a sensitive label.

If the display information matches the preset sensitive information, for example, the terminal includes the text information in the screen capture file and the preset sensitive text in the preset sensitive information database, and the terminal determines that the screen file contains the text information and the preset sensitive information database. The preset sensitive text matching, or the icon information contained in the screen capture file and the preset sensitive icon in the preset sensitive information database are more than 95%, the terminal determines that the icon information is included and the preset sensitive information in the preset sensitive information database The icon matches, the terminal determines that the screen capture file contains sensitive information, and the terminal adds a sensitive label to the screen capture file to determine whether the screen capture file involves sensitive information according to the sensitive label.

In this embodiment, the terminal identifies the display information in the screen capture file, and accurately identifies whether the screen capture file contains sensitive information, so as to monitor the transmission of the screen capture file according to the usage, and the user reminds the user that the page has sensitive information, in this embodiment. The detailed identification of the screen capture file ensures the security of the screen capture file information.

Referring to FIG. 5, based on the second embodiment of the control method for screen capture file sharing of the present application, a third embodiment of the present application is further proposed.

In the embodiment, when the screen capture file contains sensitive information, the steps when the screen capture file is sent include:

Step S31: Receive a sending instruction triggered by the screen capture file, obtain a receiving account included in the sending instruction, and determine whether the screen capture file has a sensitive label.

The terminal receives the sending instruction triggered by the screen capture file. For example, when the user selects the shared screen capture file, the user clicks the “send” virtual button on the display screen, or the user voice verbal, triggers the terminal to send an instruction, and the terminal acquires the sending instruction to include Receive the account and determine if there is a sensitive tag in the screenshot file.

In step S32, if the screen capture file has a sensitive label, the sensitive information in the screen capture file is blurred, and the transmission file is obtained.

If the terminal determines that the screen capture file has a sensitive label, the terminal performs a blurring process on the sensitive information in the screen capture file, where the blurring process refers to the blurring of the screen capture file, and the purpose is to prevent sensitive information from being leaked, for example, Mosaic the user's name, or the user's face, to get the transfer file.

Optionally, step S32 includes:

In step a1, if the screen capture file contains a sensitive label, the coordinate data of the sensitive information in the screen capture file is determined.

In step a2, the sensitive information of the corresponding coordinate position is blurred to obtain a transmission file.

In this embodiment, the terminal determines that the screen capture file contains the sensitive label, and the terminal identifies the location information of the sensitive information in the screen capture file, and the terminal performs the blur at the location information of the screen capture file sensitive information to ensure that the overall screen capture file is not affected. Accurately process sensitive information on screen capture files.

Step S33: Send the transmission file to the receiving account corresponding client to prevent leakage of personal sensitive information.

The terminal sends the transmission file to the receiving account corresponding client, for example, the user sends a screen capture file to the corresponding message on the WeChat to prevent leakage of personal sensitive information.

In this embodiment, the terminal sends the processed screenshot file to the user end, so that the leakage of the personal sensitive information is reduced, the user experience is improved, and the overall screen capture file is not affected.

Further, referring to FIG. 6, based on the second embodiment of the control method for screen capture file sharing of the present application, a fourth embodiment of the present application is further proposed.

In the embodiment, when the screen capture file does not contain sensitive information, according to the source information of the screen capture file, the step of determining the screen capture file transmission includes:

In step S41, if the display information does not match the preset sensitive information, the application to which the screen capture file belongs is determined, and the application to which the screen capture file belongs is used as the target application.

If the terminal display information does not match the preset sensitive information, that is, the screen capture file does not have obvious sensitive information, and the terminal further determines the application of the screen capture file, and uses the application of the screen capture file as the target application, and the terminal needs to determine the screen capture file. The application may be determined according to the display identifier on the screen capture file, or may be determined according to the program run by the terminal when the screen capture file is generated. Specifically, the method for determining the application of the screen capture file does not constitute a limitation on the present application.

Step S42: Determine a sensitivity level of the target application according to the preset application level table, and determine whether the sensitivity level of the target application exceeds a preset threshold.

The terminal determines the sensitivity level of the target application according to the preset application level table (the preset application level table: refers to setting according to the application type, for example, the application sensitive level of the financial information such as Alipay is the highest level), and determines the sensitivity of the target application. Whether the level exceeds the preset threshold, the preset threshold is set according to specific conditions. For example, the user screen file is the Alipay transaction interface, the Alipay transaction interface contains data information, the terminal determines that the Alipay transaction interface has no sensitive label, and the terminal will use the Alipay preset application level. The table is traversed, and the sensitivity level of the Alipay is determined to be level 3, and the terminal compares the sensitivity level 3 with the preset threshold level 2.

Step S43: If the sensitivity level of the target application exceeds a preset threshold, the screen capture file sending permission setting prompt information is output, so that the user inputs the verification standard information of the screen file sending permission.

If the target application sensitive level exceeds the preset threshold, that is, the target application is sensitive, the terminal outputs the screen capture file sending permission setting prompt information for the user to set the sending permission of the screen capture file, for example, the terminal displays “Please set the screen file to send the verification. The information prompts the user to set the verification standard information of the permission permission of the user to send the authority, and the verification authority for the operation of the screen capture file is verified by the user later.

If the sensitivity level of the target application does not exceed the preset threshold, the user's later operation is directly performed.

In the implementation, according to the source of the screen capture file, the user is prompted to set the verification standard information of the screen capture file, and when the user edits the screen capture file or other operations later, the user is verified to ensure the security of the screen capture file.

Specifically, for the application that the sensitivity level of the target application to which the screen capture file belongs exceeds the preset threshold, when the user triggers the screen capture command, the terminal needs to perform the rights verification, that is,

Step S44, receiving a screen capture file sending instruction, and acquiring identity verification information in the screen capture file sending instruction.
