Description
Technical Field
The present invention relates to a copyright protection method, and more particularly, to a copyright protection method for embedding a watermark in a display system.
Background
The internet dividend gradually disappears in the current era, and the mode of acquiring the industry pricing right by attracting users is a mode which is increasingly not profitable in the internet industry. The increasing number of secondary editing works such as B station, tremble and the like brings huge impact to the original film and television industry. Some short video bloggers finish watching a movie by cutting the movie video, such as the Valley's Amo within 5 minutes, so that many mobile phone users do not go to the movie theater to watch the original edition after finishing the cutting, which brings heavy attacks to the first movie creators.
In order to protect the copyright of online videos, a common method is to embed watermarks in existing videos, such as non-mainstream video websites, watching some dramas, and having watermarks on videos. However, the existing video embedding watermark cannot embed information for each frame, that is, cannot be used for high-speed dynamic pictures, and the watermarks of most videos are display watermarks, which affects the watching experience of users.
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 watermarks in a display system, which does not influence the impression experience of a user.
In order to prevent the online video from being stolen by a recorded screen, strike the behavior that the online video is maliciously stolen and maintain the benign ecology of the Internet online video industry, the idea of the invention is to embed invisible customized watermark information in a display system and achieve the effect of not influencing the impression experience of a user.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a copyright protection method for embedding watermark in a display system is characterized by comprising the following steps:
copying each frame of picture originally displayed twice, and assembling into two pictures represented by a two-dimensional matrix rgb value;
embedding monochrome picture information of a watermark to be embedded into a first picture, wherein the watermark information is a blank part and displays an original pixel value, and the watermark information is a valued part and displays an original pixel value of-1;
and (3) embedding the monochrome picture information of the watermark to be embedded into the second picture, wherein the watermark information is a blank part and shows the original pixel value, and the watermark information is a valued part and shows the original pixel value plus 1.
The method also comprises the step of acquiring whether the user is color blind and color weak in the interactive system in a verification code identification mode, and if so, using the color pixel value.
The method also comprises a step of judging a background part, wherein if the background part is the background part, the watermark is inserted, if the pixel value of the background part is 0, the pixel values of the two frames of pictures are 0 and 1 respectively, and if the pixel value of the background part is 255, the pixel values of the two frames of pictures are 255 and 254 respectively.
And the step of judging the background part is to use a face recognition technology, and if no face exists, the part is judged to be the background part.
The watermark monochrome picture information is two-dimensional code, bar code or character information representing a unique player.
The watermark monochrome picture information comprises time, place and model.
The invention has the technical effects that:
firstly, after the embedded video information is intercepted by a screen, only the intercepted video information is subtracted from the original video information to obtain watermark information, so that the way of revealing the video can be known, the copyright of a video creator is protected, and a healthy online video ecology is created; in continuous two-frame playing, the human eye cannot accurately distinguish the pixel value color of each frame of picture, but the human brain can automatically take the average value on the time dimension, so that the embedded watermark information is invisible for the human eye, the viewing experience of a user is not influenced when watching the video, and the embedded watermark information can be embedded for each frame of picture, so that the embedded watermark information can be used for high-speed dynamic pictures, and the better viewing experience is objectively brought to the user.
And secondly, acquiring whether the user is color blind and color weak in an interactive system by a verification code identification mode, and if the user belongs to a specific color vision identification group, preferentially using a color pixel value which is difficult to distinguish by the user, such as a color blind user, and preferentially using an r value by a red weak user. And g is preferentially used by users with greenish blindness and weak greenish. Under the condition of not influencing the use of a user, the embedded watermark information achieves the invisible effect, so that the user can feel better impression experience subjectively.
Drawings
Fig. 1 is a main flow chart of the copyright protection method for embedding watermark in video according to the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1, a main flow of the copyright protection method for embedding watermarks in videos of the present invention is shown, which includes the following steps:
initially, every two frames of pictures are the same, and each picture is composed of two-dimensional matrix rgb values;
note that the original pixel value may be a g value or a b value.
Because the human cannot accurately resolve the pixel value color of each frame of the picture in the continuous 120hz playback, the human brain automatically averages over the time dimension, 244,244,244. Therefore, the embedded watermark information is invisible to human eyes;
however, after the embedded video information is captured by the screen, the way of revealing the video can be known only by subtracting the captured video information from the original video information to obtain the watermark information, so that the copyright is protected.
Preferably, whether the user is color blind and color weak is obtained in the interactive system through 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, such as a color blind, and the r value is preferentially used by the color weak user. And g is preferentially used by users with greenish blindness and weak greenish. Under the condition of not influencing the use of a 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, and can be used for high-speed dynamic pictures, thereby bringing better impression experience to users.
Another embodiment of the invention is:
if the pixel value in the original video is a monochrome pixel value of 0 or 255 of rgb information of the original video to be embedded in the rpg, the pixel is a reference point and needs to satisfy whether the pixel is a background part or not, if the pixel is the background part, a watermark is inserted,
if the image is not the background part, the watermark is not inserted in the part, if the image is the background part, the value is 0, and the two frames of pictures are 0 and 1. If the value is 255, the two pictures are 255,254. The background picture judgment rule can use a face recognition technology, and if no face exists, the background picture is taken as a background.
Under the condition of not influencing the use of a user, the embedded watermark information achieves the invisible effect. And better impression experience is brought to the user.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
