Description
Technical Field
The invention relates to video anti-counterfeiting and anti-theft, in particular to a method for realizing video anti-counterfeiting and anti-theft through a frame insertion technology.
Background
The video anti-counterfeiting and anti-theft aims to respect intellectual property and maintain originality. The current video files can only realize anti-counterfeiting or anti-theft through an encryption mode. The common method for anti-counterfeiting is to add watermarks to video files. The essence of adding the watermark is to cover a watermark layer on a video file, which causes the influence on the video resolution and the influence on the video viewing experience, and the watermark is generally to cover a watermark layer on all video frame pictures, which increases the video capacity and makes the video occupy more storage space.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a method for realizing video anti-counterfeiting and anti-theft through a frame insertion technology, which adopts a mode of randomly adding anti-counterfeiting video frames to carry out video anti-counterfeiting and anti-theft, and because each second of pictures played in the video playing process generally comprises a plurality of frames of pictures, the picture of one frame cannot be seen clearly by naked eyes in the playing process, the film watching experience is not influenced, the quality of the video pictures is not influenced, and the film watching experience is improved.
The purpose of the invention is realized by the following technical scheme:
a method for realizing video anti-counterfeiting and anti-theft through a frame insertion technology comprises the following steps:
step 1): adding anti-counterfeiting information and anti-theft check in the anti-counterfeiting frame;
step 2): decompressing the video file to obtain continuous video frames;
step 3): randomly inserting anti-fake frames in the continuous video frames;
step 4): coding the video frame inserted with the anti-fake frame to obtain a video file with the anti-fake frame;
wherein the step 1) and the step 2) are not in sequence.
Further, the anti-counterfeiting information and the anti-theft check in the anti-counterfeiting frame are dynamically generated according to the user information and the video source information.
Further, the form of the anti-counterfeiting frame comprises anti-counterfeiting information or anti-theft check, and the anti-counterfeiting frame comprising the anti-counterfeiting information and the anti-counterfeiting frame comprising the anti-theft check are mixed and randomly inserted into the video frame;
or the anti-counterfeiting frame simultaneously contains anti-counterfeiting information and anti-theft check.
Further, the anti-theft check includes checking the identity of the playing terminal or checking the identity of the playing user.
Further, in the step 2), the anti-fake frame is randomly inserted according to the video length or an insertion strategy, and the insertion strategy can be designed by a user in a self-defined mode.
Furthermore, in the transmission process of the video file, the video slicing technology is utilized, the anti-theft check is added in the continuous transmission process, and the transmission is terminated if the check is not passed.
Further, the size tone of the anti-fake frame is consistent with the video frames before and after the insertion position.
Furthermore, the anti-counterfeiting frame is a video frame which is randomly taken out after the video file is decoded, and anti-counterfeiting information and/or anti-theft check are added to the video frame and then the video frame is inserted into the original position.
Compared with the traditional video anti-counterfeiting and anti-theft functions, the scheme has the technical advantages that:
1) the anti-fake frame is inserted by adopting the frame inserting technology, so that the coverage on the surface of the original video is not formed, and the definition of the original video file is not influenced;
2) due to the adoption of the frame insertion mode, compared with the traditional technology, the scheme only increases a plurality of frames, almost does not affect the video capacity, and occupies fewer storage resources;
3) and the random frame insertion mode is adopted, so that the cracking difficulty of anti-counterfeiting and anti-theft is increased.
Detailed Description
The technical solution of the present invention is further described in detail with reference to the following specific examples, but the scope of the present invention is not limited to the following.
A method for realizing video anti-counterfeiting and anti-theft through a frame insertion technology comprises the following steps:
step 1): adding anti-counterfeiting information and anti-theft check in the anti-counterfeiting frame;

step 3): randomly inserting anti-fake frames in the continuous video frames;
step 4): coding the video frame inserted with the anti-fake frame to obtain a video file with the anti-fake frame;
wherein the step 1) and the step 2) are not in sequence.
Optionally, a method for implementing video anti-counterfeiting and anti-theft through a frame interpolation technology, wherein anti-counterfeiting information and anti-theft check in anti-counterfeiting frames are dynamically generated according to user information and video source information.
Optionally, a method for implementing video anti-counterfeiting and anti-theft through a frame insertion technology, where the form of the anti-counterfeiting frame includes only anti-counterfeiting information or only anti-theft check, and the anti-counterfeiting frame including the anti-counterfeiting information and the anti-counterfeiting frame including the anti-theft check are mixed and randomly inserted into the video frame; or the anti-counterfeiting frame simultaneously contains anti-counterfeiting information and anti-theft check, namely, the anti-counterfeiting function and the anti-theft function are respectively arranged in different anti-counterfeiting frames, or both the anti-counterfeiting function and the anti-theft function are designed in the same frame picture.
Optionally, in order to avoid affecting the viewing experience, the interval between two adjacent anti-counterfeit frames should be at least 24 frames, because the human eye can watch and recognize exactly 24 frames/second, and cannot recognize beyond this speed.
