detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention; in addition, the following embodiments have many features and Explain that in order to avoid excessive redundancy, the refinement and interpretation are adapted to the same features under the same principle.

Please refer to FIG. 2 and FIG. 3, and FIG. 2 and FIG. 3 are common image publishing scenarios. FIG. 2 is a scene of publishing a picture in a chat application group chat, such as WeChat, QQ, etc.; FIG. 3 is a scene for publishing a picture in a web application, such as Sina Weibo. Users often post some pictures on these network platforms for the interaction between netizens. However, because network communication has information disclosure and extensive communication, not all users are well-known close friends for any user. Netizens are generally strangers with common interests; users are looking forward to themselves. I can share my life on the Internet platform, but when it comes to personal privacy information, almost all users are still spreading information. Be cautious. For the application of the network interaction class, the most common use of the user is the picture and the text, especially the picture can more intuitively represent the information, so if the picture also contains the privacy information, the user needs to hide the privacy information in the picture. In the process of the user using the application to call the image to be published, the user presses the touch screen sliding operation to trigger the adding layer operation on the sensitive information in the image, and ensures that the other information of the image is unchanged, and after adding the layer, the user can Publish the edited image directly through the app.

Referring to FIG. 4, FIG. 4 illustrates a method for hiding sensitive information in a picture by pressure according to an embodiment of the present invention. The method enables the user to filter information more flexibly and conveniently, and has convenient operation and improved user experience. The method specifically includes steps 101 to 103.

Step 101: The interactive application acquires a picture to be published.

The interactive application referred to in the present invention is a broad concept, including all applications that can be used for users to post messages, such as QQ, Post Bar, WeChat, Weibo, Renren, Maopu, Yibai, Jingdong, Taobao, Mobile Banking. , mobile business hall, facebook, Twitter, instagram, and major community forums. The user can enter the message publishing interface through some prior art operations. According to the function setting of the interactive application, when the user selects to publish the image, there are two image acquisition methods, one is to call the camera software provided by the smart terminal or a third party. The camera software directly shoots, and the other is to call the image software of the smart terminal or the third-party library software to select the image that has been stored before in the smart terminal; once the image is called, the interactive application obtains the image to be published, and the image to be released Often in preview mode. The smart terminals mentioned in this patent include, but are not limited to, terminal devices such as smart phones, tablet computers, wearable devices, and the like, and particularly mobile terminal devices.

Step 102: Detect a touch screen sliding of the user on the picture to be released and a pressure value of the touch screen sliding.

Wherein, when the user performs a touch screen operation on the picture to be released, the smart terminal detects the position where the user touches the screen, and also detects the pressure value of touching the screen, which can be integrated through the pressure of the screen of the smart terminal. Devices such as sensors are available.

Step 103: When the pressure value is greater than the preset threshold, the layer processing is performed on the area where the picture to be released is being touched by the touch screen; wherein the area where the picture to be released is being touched by the touch screen corresponds to sensitive information, and the added Layers are used to make sensitive information invisible.

This is one of the innovations of the present invention, which triggers the addition of layers to the picture by means of a heavy press. In the prior art, the touch operation of the heavy pressure and the normal force is not distinguished, and the preset threshold value referred to in the present invention is larger than the pressure sensing value that can trigger the normal operation. For example, when the pressure applied by the user reaches F1, the user can only preview and select the picture to be published; and when the pressure applied by the user reaches F2, the additional layer operation of the picture to be posted can be triggered; wherein F2 is greater than F1, and F2 is The preset threshold can be set by the smart terminal manufacturer or customized by the user.

The sensitive information referred to in the embodiment of the present invention is also a broad concept, and the sensitive information includes but is not limited to: contact information, account information, password information, time information, location information, person identity information, or property information. Or the content that the user wants to hide is sensitive information. On a more general level, the user can also use the technical scheme of the present invention to perform the graffiti operation to change the original appearance of the picture, and the user can perform the graffiti according to his or her wishes and interests, and then the area where the original picture is changed can be performed in the area corresponding to the sensitive information. Equivalent. Sensitive information is usually a part of a picture. Therefore, one of the advantages of the present invention is to increase the layer processing of the local information and increase the convenience of the operation, while keeping the theme of the picture unchanged.

The specific operation of the user is shown in Figure 5. Figure 5 is a schematic diagram of the method of adding pressure to increase the layer. Figure. For example, if the preset threshold is 2N, assuming that the force applied by the user is F, when F is less than or equal to 2N, no editing operation is triggered on the picture, as shown by the dotted line in FIG. 5; once F is greater than 2N, the pair is triggered. The picture adds the operation of the layer, as shown by the solid black line in Figure 5. As a supplementary explanation, there are many ways to add a layer, and solid dotted lines in the figure are not specifically limited, and are merely illustrative. Adding layers to areas where the published image is being pressed and swiped includes, but is not limited to, blurring, blurring, or mosaic processing, as long as it is capable of making image sensitive information indistinguishable or completely invisible. It is within the scope of the present invention to be equivalently substituted with an added layer.

In a specific implementation process, when the pressure value is greater than the preset threshold, the pressure value applied by the user is larger, and the added layer makes the corresponding sensitive information less visible, for example, the position of the image after the touch of the screen is 5N. The sharpness of the picture is lower than that of the picture position after the sliding of the 3N force.

In addition, the user can trigger the editing operation of the image to be published by touching the screen on the screen, that is, the image editing function that is included in the interactive application is triggered by the pressure, or the third-party software that is being invoked by the interactive application is triggered by the pressure. Picture editing features. It should be understood that the touch screen operation on the to-be-published picture mentioned in the present invention means that the touch screen is displayed on the display position in the current screen corresponding to the picture to be released, and the touch screen operation of the touch screen position can trigger the Identification and editing operations of the pictures to be published.

The implementation of the foregoing technical solution is also various due to the difference of the user operation scenarios. The foregoing method will be described in detail in a specific example manner, and any technical solution and application scenario that can be equivalent and replaced should be It is within the scope of protection of the present invention.

Life...etc.; however, he wants to publish the object of the majority of netizens. Many people may not know what his name is, nor do he know that his identity is a student. Therefore, for the user, the name and identity are privacy. And student fares indicating student status may also reveal identity information. The user initially obtains this picture by means of a screen capture (as shown in the left figure of Figure 6, without the ellipse mark), and is stored in the memory of the smart terminal. When the user wants to publish the image through the interactive application, the interactive application's own gallery application or third-party gallery application can be called to call the image. Since the image has sensitive information, the ellipse area shown in the left figure of FIG. 6 (specific location) Not limited, as long as the area corresponding to the sensitive information is equivalent), the user can perform the heavy pressing operation in the two elliptical areas. The heavy pressure will trigger the picture editing operation, and after triggering the picture editing operation, If the screen strength is greater than the preset threshold, the layer will be added to the area being swiped. The user can press and slide on the screen position corresponding to the sensitive information to increase the layer. The right picture in Fig. 6 is a possible effect picture, that is, sensitive information such as name, identity, and fare are covered.

As a supplementary description, the graphic labeling in the drawings in the embodiment of the present invention is merely a symbol, and does not limit the position of the touch screen and the size of the touch screen in actual operation, as long as the user uses the diversity of operations, as long as The function that can be equivalent to the function of the operation function of the present invention should belong to the technical solution to be protected by the present invention, and will not be described below.

In the specific implementation process of the embodiment of the present invention, if the user finishes editing the current picture After the completion, if you want to publish multiple images, you can edit the sensitive information in the image every time you call an image; then publish the edited multiple images to be published.

In the specific implementation process of the embodiment of the present invention, after the user presses the editing operation on the picture for the first time, the user can display a function icon on the picture editing interface, which is used to indicate that the picture is in the editing state of the added layer. If the user edits the layer incorrectly, such as overwriting non-sensitive information, or the added layer affects the aesthetics of the original image, the user can remove the previous step or remove all the added layers by clicking the function icon. The specific settings are set by the smart terminal by default or by the user. In addition, the photo editing interface can also display another function icon to indicate the completion of the editing operation of adding layers. After the user completes the editing operation of adding a layer, by clicking on the other function icon mentioned above, it means that the current picture is edited and can be released at any time.
