Based on partial contents of the background art, the information hiding method in the related art can only hide the designated control area inside the application program, and cannot hide the user-defined information according to the user requirements, so that the method has certain limitations in application scenes.
The applicant finds that after a target image of a user interface is obtained, target information can be identified from the target image, and then the target information is hidden based on a preset hiding mode. Since the target information is the information which is pre-defined by the user, the information which is pre-defined by the user can be hidden.
The information hiding method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, the information hiding method may include:
s101, acquiring a target image of a user interface.
S102, hiding the target information based on a preset hiding mode under the condition that the target information is recognized from the target image; the target information is information which is customized by a user in advance.
According to the information hiding method, after a target image of a user interface is obtained, target information is recognized from the target image, and then the target information is hidden based on a preset hiding mode. Because the target information is the information which is pre-defined by the user, the information hiding method can hide the information which is pre-defined by the user.
To more simply and directly acquire the still frame image, in one embodiment, when the target image is the still frame image, acquiring the target image of the user interface may include:
and acquiring the static frame image by adopting a screen capturing and/or screen recording mode.
The static frame image can be acquired more simply and directly by adopting a screen capturing and/or screen recording mode.
In order to more efficiently acquire the target information, in an embodiment, in a case where the target information is recognized from the target image, before hiding the target information based on a preset hiding manner, the method may further include:
and identifying the target image by adopting a preset information identification mode to obtain target information. In one embodiment, the preset information recognition mode is an Artificial Intelligence (AI) recognition mode.
By adopting an AI identification mode, the target information can be acquired more efficiently.
In order to hide the target information more comprehensively, in an embodiment, hiding the target information based on a preset hiding manner may include:
acquiring a first position and a first size of an area where target information is located;
determining a second size of the target object corresponding to a preset hiding mode according to the first size; wherein the second size is not less than the first size;
displaying the target object having the second size at the first position. In one embodiment, the preset hiding manner may include at least one of mosaic blocking, text replacement display, and image replacement display.
Since the second size of the target object is not smaller than the first size of the target information, the target information can be hidden more comprehensively.
In one embodiment, before hiding the target information based on a preset hiding manner, the method may further include:
and setting a mapping relation between a preset hiding mode and the target information.
In one embodiment, the target information may include at least one of text information and image information.
The target information may be user-defined private content, and the information hiding method is described below by taking the private content as an example. As shown in fig. 2, another information hiding method provided in the embodiment of the present application includes:
s201, selecting an application needing privacy protection by a user.
The user may select one or more applications that require privacy protection that will enable the relevant interfaces, both within the application and notifications sent by the application.
And S202, customizing privacy contents.
The user can customize the private content, and the private content can be in the form of characters or images as a basis for identifying and matching in the application.
S203, setting a privacy processing mode.
The processing mode of the content of the privacy zone set by the user can be a default smearing mode such as mosaic, and can also be a mode of replacing the content by user-defined characters or pictures.
And S204, acquiring a static frame image in the interface.
The Android system screen display process is based on a 'producer-consumer' mode, and in short, graphics streams, i.e., graphics information for drawing to a screen, are generated by a producer first, and then the graphics streams are consumed by a consumer and rendered to the screen, so that the displayed key information is in the graphics streams. The update of a dynamic interface (such as an animation video or an interface slide) is actually realized by continuously updating and displaying a large number of static frame images, so that the update of the dynamic image is a process of circularly executing a process of generating a static graphic stream and sequentially rendering.
There are many ways to capture the still frame image, and screen capture or screen recording is the simplest and most straightforward way. Wherein a Bitmap (Bitmap) containing original image information can be acquired by screen capture. Because the dynamic interface can be understood as that the static frame images are continuously switched and refreshed, in order to realize the real-time identification processing of the dynamic interface, the frequency of refreshing the static frame of the screen is required to be followed for real-time screen capture so as to continuously obtain the static frame images.
And S205, identifying the privacy content in the static frame image.
The identification of the dynamic interface is to identify the static frame image obtained in each step S204, and after the characters and the pictures in the static frame image are obtained, the obtained characters and pictures are compared with the privacy content set in step S202 and matched with the obtained privacy content.
Fig. 3 shows an example of identification of the private content in the still-frame image at a certain time, and the customized private content is shown on the right side of fig. 3. For the still frame image on the left side of fig. 3, matching is performed by AI identification, and the X coordinate and the Y coordinate of the area containing the privacy content in the still frame image, and the width and the height of the privacy content itself are identified. When matching is performed through AI recognition, the matching may be of the same type (for example, matching text with text, matching picture with picture), or may be of different types (for example, matching text with picture). For example, the corresponding text information contained in the picture can be matched and identified as the private content.
S206, hiding the privacy content.
And adding a floating window which does not accept the touch event to the screen according to the size and the position of the identified privacy content, wherein the content displayed in the floating window is determined according to the privacy processing mode set in the step S203. In step S204, the static frame image is captured in real time according to the change of the dynamic interface, so that the position and size of the floating window are dynamically updated according to the real-time recognition condition, so as to hide the privacy content during sliding. Briefly elaborating a real-time mobile updating mode of a floating window for blocking privacy content:
as shown in step S204, the identified object is each static frame image, and in the process of interface sliding or continuous update, the static frame images are continuously switched, so that the privacy content shown in fig. 3 may also have position movement or size change (enlargement or reduction), the corresponding specific parameters are the X coordinate, the Y coordinate, the width and the height in fig. 3, and the change of the position width and the height is reflected in the currently rendered static frame image, so as to capture the current static frame image in real time, identify the position size of the privacy content, and update the position and the size of the floating window in real time according to the parameter of the privacy content in the current static frame image, so as to implement real-time coverage of the floating window on the privacy content.
As shown in fig. 4, the avatar (i.e., a1) and the "grayish wolf" (i.e., a2) in the left static frame image in fig. 4 are both private contents, the display effect obtained by hiding a1 is B1, and the display effect obtained by hiding a2 is B2.
The application implementation example can realize user-defined privacy content, and the privacy content is hidden, replaced and displayed in the application according to a preset hiding mode, so that the privacy protection effect is achieved, and the user experience is further improved. Moreover, the core technical scheme does not depend on a frame and controls in the application, the system application of a mobile phone manufacturer can be realized, the third-party application can also be realized after obtaining certain authority, and the application range is wider.
