B, secondary editing works such as trembling sounds are increased increasingly, and huge impact is brought to the original film industry. Some short video bloggers finish watching a movie by editing the movie video for 5 minutes, as Gu Amo, resulting in many cell phone users not going to the theatre to see the original edition after finishing watching the editing, which gives a heavy hit to the first movie creator.
In order to protect the copyright of online video, a common method is to embed a watermark in the existing video, such as a non-main stream video website, and watch some beauty dramas, and the watermark is present on the video. However, the existing video is embedded with watermarks, information can not be embedded for each frame, and the video can not be used for high-speed dynamic pictures, and the watermarks of most videos are displayed watermarks, so that the watching experience of users is affected.
This is a disadvantage of the prior art.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problem to be solved by the invention is to provide a copyright protection method for embedding watermark in a display system, which does not influence the visual experience of a user.
In order to prevent online videos from being stolen by a screen, the online video online processing method and device strike the behavior that the online videos are maliciously stolen, and maintain benign ecology of the online video industry of the Internet, the idea of the invention is to embed invisible customized watermark information in a display system, and achieve the effect of not affecting the viewing experience of users.
The technical scheme adopted for solving the technical problems is as follows:
a copyright protection method for embedding watermark in display system is characterized by comprising the following steps:
copying two pictures of each frame of original display, and assembling two pictures represented by a two-dimensional matrix rgb value;
embedding watermark monochrome picture information to be embedded into a first picture, wherein the watermark information is blank part, displaying original pixel value, the watermark information is valued part, and displaying the watermark information as original pixel value-1;
embedding watermark monochrome picture information to be embedded into a second picture, wherein the watermark information is blank part, displaying original pixel value, the watermark information is valued part, and displaying as original pixel value +1;
and the method further comprises the step of acquiring whether the user is a achromatopsia user or not in the interactive system in a verification code identification mode, and if so, using the pixel value corresponding to the achromatopsia user.
The method further comprises the step of judging the background part, if the background part is the background part, the watermark is inserted, if the background part pixel value is 0, the two frames of picture pixel values are respectively 0 and 1, and if the background part pixel value is 255, the two frames of picture pixel values are respectively 255 and 254.
The step of judging the background part is to use face recognition technology, and if no face exists, the background part is judged.
The watermark monochrome picture information is two-dimensional code, bar code or text information representing a unique player.
The watermark monochrome picture information comprises time, place and model.
The invention has the technical effects that:
1. according to the method, after the embedded video information is intercepted by the screen, the path of revealing the video can be known only by differencing the intercepted video information with the original video information to obtain the watermark information, so that the effect of protecting the copyright of a video creator is achieved, and a healthy online video ecology is created; in the continuous two-frame playing, the human eyes can not accurately distinguish the pixel value color of each frame of picture, but the human brain automatically takes an average value in the time dimension, so that the embedded watermark information is invisible to the human eyes, the viewing experience of a user is not affected when the user views the video, and the embedded watermark information can be used for high-speed dynamic pictures as the information can be embedded for each frame of picture, so that the user is objectively provided with better viewing experience.
2. And acquiring whether the user is a achromatopsia user or not in the interactive system in a verification code identification mode, if the user belongs to a specific achromatopsia identification group, preferentially using color pixel values which are difficult to distinguish by the user, such as achromatopsia, and preferentially using r values by the achromatopsia user. Green blindness, green weak users prefer to use g values. Under the condition of not influencing the use of a user, the embedded watermark information achieves the invisible effect, so that the user can subjectively feel better looking and experiencing.
Drawings
Fig. 1 is a main flow chart of a copyright protection method of embedding watermark in video of the present invention.
Detailed Description
The invention will now be described in further detail with reference to the drawings and examples.
Referring to fig. 1, the main flow of the copyright protection method for embedding watermark in video of the present invention is shown, which comprises the following steps:
step 10, taking video as an example in a display system, if the original video frame rate is 60hz, copying each frame of picture into two copies, loading into 120hz,
each two frames of pictures are the same at the beginning, and each picture consists of a two-dimensional matrix rgb value;
step 20, watermark monochrome picture information to be embedded, (watermark information protects unique uuid, determines player, (is not limited to two-dimensional code, bar code and text information)) is embedded into a first picture, watermark information is blank part, original pixel value is displayed, watermark information is valued part, namely monochrome image part is displayed as original pixel value r value-1, if original pixel point is (244,244,244), and pixel point is (243,244,244) after watermark coverage;
step 30, embedding watermark monochrome picture information to be embedded into a second picture, wherein the watermark information is blank part, displaying original pixel value, the watermark information is valued part, namely monochrome image part, displaying original pixel value r value +1, if original pixel point is (244,244,244), and pixel point is (245,244,244) after watermark coverage;
note that the original pixel value may be a g value or a b value.
Because the person cannot accurately resolve the pixel value color of each frame of picture in successive 120hz playback, the human brain will automatically average in the time dimension, i.e. (244,244,244). The embedded watermark information is invisible to the human eye;
however, for the video information which is embedded after being intercepted by the screen, the path of revealing the video can be known only by solving the watermark information by making the difference between the intercepted video information and the original video information, thereby achieving the effect of protecting the copyright.
Preferably, whether the user is a achromatopsia color weak user is obtained in the interactive system in a verification code identification mode, if the user belongs to a specific color vision identification group, the color pixel value which is difficult to distinguish by the user is preferentially used, for example, the r value is preferentially used by the achromatopsia color weak user. Green blindness, green weak users prefer to use g values. Under the condition of not influencing the use of the user, the embedded watermark information achieves the invisible effect, and better impression experience is brought to the user.
The invention can embed information for each frame of picture, so that the invention can be used for high-speed dynamic pictures, thereby bringing better looking and feeling experience for users.
Another embodiment of the invention is:
if the pixel value in the original video is 0 value or 255 value of the monochrome pixel value of the rgb information of the original video to be embedded in rpg, the pixel point is a band reference point, whether the background part is needed to be satisfied, if the background part is needed, the watermark is inserted,
if the watermark is not inserted into the background part, and if the watermark is inserted into the background part, the watermark is 0, and two frames of pictures are 0 and 1. If the value is 255, the two-frame picture is 255,254. The background picture judgment rule can use a face recognition technology, and if no face exists, the background picture judgment rule is background.
Under the condition of not affecting the use of users, the embedded watermark information achieves the invisible effect. And better looking experience is brought to the user.
The present invention is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical matters of the present invention can be made by those skilled in the art without departing from the scope of the present invention.
