Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

In this example embodiment, a peep-proof method based on out-of-order coding of image pixel values is provided first, and the method can be applied to a terminal device with a display screen, for example, a mobile terminal such as a mobile phone, a personal digital assistant, a notebook computer, a tablet computer, a smart watch, or a non-mobile terminal such as a desktop computer, a smart television, etc. Referring to what is shown in fig. 1, the method may include: step S101 to step S104.

Step S101: the virtual machine establishes connection with the zero terminal;

step S102: the virtual machine receives user image data sent by the zero terminal and judges whether a peeping event occurs according to the user image data;

step S103: if the peeping event occurs, the virtual machine performs pixel value out-of-order coding on the desktop image to obtain image data;

step S104: and the virtual machine sends the image data to a zero terminal.

By the peep-proof method based on the out-of-order coding of the image pixel values, after the zero terminal is connected with the virtual terminal, the virtual terminal normally codes the desktop image and sends the desktop image to the zero terminal, and meanwhile, the zero terminal performs peep-proof monitoring; when a peeping event is found, the zero terminal carries out disorder coding transmission on the desktop image, and the zero terminal obtains a disorder code image after decoding; when the peeping event is eliminated, the virtual terminal encodes and transmits the desktop image again normally, and the zero terminal obtains the normal desktop image after decoding, so that information leakage is prevented.

Hereinafter, each step of the above-described method in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 2.

In step S101, the zero terminal logs in to the virtual machine through the correct account number and password, so as to establish a connection between the virtual machine and the zero terminal.

In step S102, after the virtual machine and the zero terminal are connected, the currently used user image data needs to be compared with the legal user image data, so as to ensure that the currently used user is a legal user.

Before a legal user uses an intelligent terminal (zero terminal), a camera firstly collects images of the legal user sitting in front of a screen when the legal user uses the zero terminal, and the collected images are used as reference images for subsequent image comparison; on one hand, the face can be identified from the image data of the current user and used as a reference face in the subsequent face recognition, and on the other hand, the image data of the real-time user can be compared with the image data of the legal user in the subsequent process, so that whether the use state of the user is changed or not is judged.

In order to ensure that the user in the acquired user usage image in the step is a legal user of the current intelligent zero terminal, the validity of the current user needs to be verified in other authentication modes before the image is acquired.

In step S103 and step S104, during the process of using the intelligent zero terminal by the user, the camera continuously collects the user used image according to a preset period, and the period can be set according to the actual needs, which is not limited herein.

In addition, determining whether a suspicious usage condition has occurred includes, but is not limited to: whether the user is a legal user, whether the legal user leaves the seat, whether people outside the legal user watch the screen image, whether other people take photos or not, and the like are judged.

The above-mentioned judgment of whether the peep-screen event occurs is implemented by an AI (Artificial Intelligence ) module, and the judgment result of the AI module is used as a judgment condition for whether to start the peep-back event. In actual implementation, the AI module may determine whether a suspicious shooting event occurs in a variety of ways. The AI module is not an important point of the present application, and the working principle of the AI module is the prior art, and the specific principle thereof is not described herein.

When an AI identification module of a VGTP-R end (zero terminal) detects a suspicious shooting event, directly starting a peeping flow, comprising the following steps: and after decoding each image macro block which is received from the VGTP-S and is subjected to out-of-order coding, directly arranging according to the decoding sequence to obtain a final display image. Therefore, the sequence of the macro blocks which are arranged in disorder is not restored, so that each macro block in the whole frame of the obtained image is arranged according to the sequence which is arranged in disorder, namely, for the image frame which is obtained through processing, the information in the whole frame is disordered, and therefore, even if a suspicious peeping user successfully implements peeping behavior, effective information cannot be obtained, and the safety of the user information is ensured.

In one embodiment, the method further comprises: and if the peeping event does not occur, the virtual machine normally codes the desktop image to obtain image data.

Specifically, the VGTP-R intelligent terminal receives the encoded image, restores the original video image by decoding, and displays the source video image obtained by decoding on a screen. The method specifically comprises the following steps:

after receiving the transmitted messy code image data, the receiving end (zero terminal) analyzes the image data to obtain the image data, and then the desktop image can be obtained.

It will be appreciated that in order to better protect privacy security, techniques such as adding authentication mechanisms, digital watermarks, etc. during decoding may be considered.

In one embodiment, the step of determining whether a peeping event occurs according to the using user image data includes: the zero terminal identifies the image data of the users and judges the number of the identified current users; if the user is not detected, judging that a peeping event occurs; and if one or more using users are detected, carrying out subsequent judgment.

Specifically, when the AI module receives a current use image of the user, the AI module performs face recognition on the current use image of the user; and comparing the identified face image with a face image of a legal user prestored in the system, and judging whether a suspicious shooting event occurs. The AI module carries out face recognition on the currently received use image of the user; the AI module judges the number of the identified faces; and carrying out subsequent judgment according to the identification result so as to determine whether a suspicious shooting event occurs. If the face is not detected, the legal user is considered to leave the seat, and at this time, the reverse shooting event is directly started (namely, the occurrence of the peeping event is judged).

In one embodiment, the step of performing subsequent judgment if one or more of the users are detected includes: if one user is detected, judging whether the user is a legal user or not according to legal user image data; if not, judging that a peeping event occurs; if yes, continuing to judge whether the action of the legal user is suspicious, and if yes, judging that a peeping event occurs.

If a plurality of using users are detected, judging whether the legal users are contained in the plurality of using users or not; if the peep event does not exist, judging that the peep event exists; if yes, continuing to judge whether the actions of the legal users and the rest of the using users are suspicious, and if yes, judging that a peeping event occurs.

Specifically, as shown in fig. 2, if a face is detected, the face is firstly compared with the face of a legal user stored locally, if the faces are not the same, the current user is determined to be not the legal user, the peeping process is directly started, if the faces are the same, whether the current user has suspicious actions similar to photographing is continuously judged, and if the faces are the same, the peeping process is started; otherwise, the subsequent discrimination flow is continued without any processing.

If a plurality of faces are detected, firstly judging whether the faces of legal users are included, if not, directly starting a peeping flow, if so, continuously judging whether suspicious actions similar to photographing occur to all people appearing in the current use image of the user, and if so, starting the peeping flow; if not, no processing is carried out, and the subsequent discrimination flow is continued.

In one embodiment, the step of performing out-of-order encoding on pixel values of the desktop image by the virtual machine to obtain image data includes: establishing a new pixel matrix according to the pixel matrix of the desktop image; and marking the pixel values of the desktop image, and scrambling and storing the pixel value sequence of the desktop image into the new pixel matrix to finish the pixel value scrambling coding.

Specifically, the pixel value disorder algorithm flow is as follows: the VGTP-S end transforms the image by means of mathematics or other technology to make it an unordered image for transmission. The method comprises the steps of disturbing the pixel value sequence of an image, creating an empty pixel matrix according to the pixel matrix of the acquired image, marking each pixel value of the acquired image, determining the coordinates of other pixels according to the coordinates of a pixel, moving the a pixel to a b pixel position, moving the b pixel to a c pixel position, … …, and the like, storing the pixel to the newly created pixel matrix, and finishing the picture disorder.

The coordinate relationship of a pixel and b pixel can be as follows:

1) The a pixel and the b pixel are two pixels adjacent left and right;

2) The a pixel and the b pixel are two pixels spaced left and right (1 or more);

3) The pixel a and the pixel b are two pixels which are adjacent up and down;

4) The a pixel and the b pixel are two pixels spaced up and down (1 or more);

5) The pixel a and the pixel b are two obliquely adjacent pixels;

6) The a pixel and the b pixel are two pixels diagonally spaced (1 or more);

7) The a pixel and the b pixel are two random pixels in the image;

the edge pixel shifting method can be as follows:

1) Moving in a row, the last of the rows moving to the first of the next row;

2) Move in a column, the last of which moves to the first of the next column;

3) Moving in an oblique direction, wherein the last oblique direction moves to the first oblique direction of the next oblique direction;

4) Random movement does not involve edge pixels, the last pixel being moved to the position of the a pixel;

the same or different disorder modes are repeated for a plurality of times, so that the disorder modes are converted into disorder pictures which are difficult to recognize, and then the disorder pictures are transmitted to a VGTP-R end for decoding. In the image transmission process, the correlation of the image matrix is destroyed by rearranging the image pixel matrix, so that an illegal interceptor cannot obtain original image information from the disordered image, thereby realizing the encryption of the information.

And displaying the image with the pixel values subjected to out-of-order coding, namely, after the VGTP-S terminal carries out-of-order coding on the pixel values of the image, sending the image to the out-of-order image displayed after being decoded by the VGTP-R terminal, wherein the pixel information is chaotic and the picture is fuzzy and irregular for the image obtained through the processing, so that effective information cannot be obtained even if a suspicious peeping user successfully carries out peeping, and the safety of the user information is ensured.

It should be noted that although the steps of the methods of the present disclosure are illustrated in the accompanying drawings in a particular order, this does not require or imply that the steps must be performed in that particular order or that all of the illustrated steps be performed in order to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform, etc. In addition, it is also readily understood that these steps may be performed synchronously or asynchronously, for example, in a plurality of modules/processes/threads.

Further, in the present exemplary embodiment, another anti-peeping method based on out-of-order encoding of image pixel values is also provided. Referring to fig. 3, the method may include. Wherein: step S201 to step S203.

Step S201: the zero terminal is connected with the virtual machine;

step S202: the zero terminal collects the image data of the current user and sends the image data to the virtual terminal;

step S203: and the zero terminal receives the image data and analyzes the image data to display a desktop image.

Specifically, as shown in fig. 4, after the zero terminal and the virtual terminal are connected, the virtual terminal normally encodes the desktop image and sends the desktop image to the zero terminal, and meanwhile, the zero terminal performs peep-proof monitoring; when a peeping event is found, the virtual terminal carries out-of-order encoding transmission on the desktop image, and a zero terminal obtains an out-of-order image after decoding; when the peeping event is eliminated, the virtual terminal encodes and transmits the desktop image again normally, and the zero terminal obtains the normal desktop image after decoding, so that information leakage is prevented.
