The preset algorithm may be any hash algorithm, such as an MD5 algorithm, and the embodiment of the present application does not limit the specific algorithm used.

102. Split the anti-counterfeiting mark to obtain multiple anti-counterfeiting segments.

In this embodiment of the present application, the number of anti-counterfeiting segments that can be split for anti-counterfeiting is not limited, and can be specifically determined according to the length of the anti-counterfeiting mark, the frame rate of the video, and the like. For example, in a specific implementation, the anti-counterfeiting mark can be divided into 3-100 anti-counterfeiting segments, and multiple anti-counterfeiting segments are added to a video that can be played in a few seconds (eg, 5s).

103. Add the multiple anti-counterfeiting segments to multiple video frames of the video sequentially.

It should be noted that, part or all of the execution bodies of 101 to 103 may be applications located in the terminal, or may also be functional units such as plug-ins or software development kits (Software Development Kit, SDK) in the application setting the terminal, or It may also be an application located in a network-side server, which is not particularly limited in this embodiment of the present application.

In this way, multiple anti-counterfeiting segments can be subsequently extracted from different video frames and spliced to obtain a complete anti-counterfeiting mark, so that the video can be identified as piracy based on the anti-counterfeiting mark, so as to effectively prevent the video from being pirated.

In addition, by adopting the technical solution provided by the present application, since the anti-counterfeiting mark of the video is divided into multiple anti-counterfeiting segments and added to different videos respectively, the whole video mark can be effectively prevented from being cracked when added in one video frame, which improves the performance of the video. Security of anti-counterfeiting marks to improve video anti-piracy effect.

In addition, with the technical solution provided by the present application, since the anti-counterfeiting mark of the video is divided into multiple anti-counterfeiting segments and added to different videos respectively, it can be avoided that the entire video mark is added in one video frame due to the data volume of the video mark. It is large and affects the smoothness of subsequent video playback, effectively ensuring the user's video viewing experience.

FIG. 2 is a schematic flowchart of splitting the anti-counterfeiting mark to obtain a plurality of anti-counterfeiting segments according to an embodiment of the present application. As shown in FIG. 2, based on the embodiment shown in FIG. 1, 102 may include:

201. Split the anti-counterfeiting mark into multiple parts to obtain multiple pieces of anti-counterfeiting data.

202. Determine the positions of the anti-counterfeiting segments including each piece of anti-counterfeiting data in the plurality of anti-counterfeiting data in the video frame respectively.

203. Encapsulate the skip run identifier, sequence start identifier information, the number of anti-counterfeiting segments corresponding to the plurality of anti-counterfeiting data, the first anti-counterfeiting data and the index information of the next segment to obtain the first anti-counterfeiting data security section.

Among them, the sequence start identification information is used to identify the beginning of the first anti-counterfeiting segment, which can be preset, such as 1011; the next segment index information is used to indicate the position of the next anti-counterfeiting segment in the video frame; skip run identification is used for Indicates that the corresponding data block will not be played by the player.

204. For each anti-counterfeiting data other than the first anti-counterfeiting data and the last anti-counterfeiting data in the plurality of anti-counterfeiting data, respectively, compare the skip run identifier, the number of anti-counterfeiting segments, the anti-counterfeiting data, and the index information of the lower segment. Encapsulation is performed to obtain an anti-counterfeiting segment of the anti-counterfeiting data.

205. Encapsulate the skip run identifier, the number of anti-counterfeiting segments, and the last anti-counterfeiting data to obtain an anti-counterfeiting segment of the last anti-counterfeiting data.

It should be noted that the above operations 203 to 205 do not have strict execution order restrictions, and may be performed in any order or simultaneously, and the embodiment of the present application only exemplarily shows a case of sequential execution.

As shown in FIG. 3 , it is a schematic diagram of a format of an anti-counterfeiting section of the first anti-counterfeiting data in an embodiment of the present application. Among them, the anti-counterfeiting section of the non-first anti-counterfeiting data does not include the sequence start identification information relative to the anti-counterfeiting section of the first anti-counterfeiting data, and the anti-counterfeiting section of the last anti-counterfeiting data does not include the anti-counterfeiting section relative to other non-first anti-counterfeiting data. The next index information. The order of several parts of data included in each anti-counterfeiting segment can be adjusted, and is not limited to the order of the embodiment shown in FIG. 3 .

Based on this embodiment, after the position of each anti-counterfeiting segment in the video frame is determined, the position index (lower index information) of the next anti-counterfeiting segment can be carried through the previous anti-counterfeiting segment in turn. After reading the position in the frame and reading the index information of the next segment in the first anti-counterfeiting segment, the anti-counterfeiting data in the adjacent next anti-counterfeiting segment and the index information of the next segment in the next anti-counterfeiting segment adjacent to the next anti-counterfeiting segment can be read in turn, so that And so on, thereby improving the security of the anti-counterfeiting data, thereby improving the security of the whole anti-counterfeiting mark. In addition, since the data block including the anti-counterfeiting segment carries the skip run flag, it will not be played by the player, and thus will not affect the video playback effect.

As shown in FIG. 4 , it is a schematic diagram of a correspondence between a video frame and an anti-counterfeiting segment in an embodiment of the present application.

FIG. 5 is a schematic flowchart of determining the position of each anti-counterfeiting segment in a video frame according to an embodiment of the present application. As shown in FIG. 5, based on the embodiment shown in FIG. 2, 202 may include:

501. Based on a preset hash algorithm, map the anti-counterfeiting mark to a value within a specified value range.

The specified numerical interval range may be determined according to the specific video coding standard and the adopted frame format. For example, in one embodiment, the specified numerical interval range may be 1-5. The embodiment of the present application does not limit the specific value of the specified numerical interval range.

502. Use the one value as the position of the first anti-counterfeiting segment in the video frame.

503. Determine the positions of the other non-first anti-counterfeiting segments in the video frame according to a preset method.

Based on this embodiment, the anti-counterfeiting mark is mapped to a value within a specified numerical range based on a preset hash algorithm as the position of the first anti-counterfeiting segment in the video frame, which can improve the security of the position of the first anti-counterfeiting segment It is not easy to be cracked and erased, so that the positions of other non-first anti-counterfeiting segments cannot be determined and read data, which improves the security of the entire anti-counterfeiting mark and makes it difficult to remove the anti-counterfeiting mark.

Optionally, in some of the possible implementations, in 503, a value may be randomly determined within the specified value interval as the position of each other anti-counterfeiting segment in the video frame, that is, for each other anti-counterfeiting segment. , can randomly determine its position in the video frame, in this way, due to the random positions of other anti-counterfeiting segments in the video frame, it is not easy to determine the position and read, which can improve the security of the anti-counterfeiting segment information, thereby improving the security of the anti-counterfeiting mark. safety.

Or, in some of the possible implementation manners, in 503, it is also possible to determine the location of the next anti-counterfeiting segment in the video frame according to the position of each anti-counterfeiting segment in the plurality of anti-counterfeiting data in the video frame and the preset rule. The preset rules can be determined according to the actual situation. For example, in one embodiment, the position of each anti-counterfeiting segment in the video frame can be gradually decreased by 1 or increased by 1 as the next anti-counterfeiting segment in the video frame. A preset function can also be used to determine the position of the next anti-counterfeiting segment in the video frame based on the position of each anti-counterfeiting segment in the video frame. The embodiment of the present application does not limit the specific manner of the preset rule. In this way, since it is necessary to determine the position of the next anti-counterfeiting segment in the video frame based on the position of each anti-counterfeiting segment in the video frame and the preset rules, it is impossible to determine the location of the next anti-counterfeiting segment without knowing the preset rules. The position in the video frame, thereby preventing the anti-counterfeiting data in the next anti-counterfeiting segment from being read, can improve the security of the anti-counterfeiting segment information, thereby improving the security of the anti-counterfeiting mark.

The embodiments of the present application may be applicable to video coding standards and videos of any format. In a specific implementation, each anti-counterfeiting segment can be inserted into a corresponding position in the video frame.

For example, in the H.264/AVC video coding standard, the original code stream (bare stream) is composed of Network Abstract Layer Unit (NALU) one after another, and the entire system framework is divided into two levels: video Coding layer (Video Coding Layer, VCL) and network abstraction layer network abstraction layer (Network AbstractLayer, NAL). Wherein, an original NALU usually consists of three parts: a start code (StartCode), a NALU header (NALU Header) and a NALU payload (NALU Payload), wherein the NALU payload is the main body of the NALU. The main body of the NALU includes slice headers and on-chip data, 1 frame=n slices (slices), 1 slice=n macroblocks (MB), and 1 macroblock=16×16 yuv data. Among them, the macroblock is the main bearer of video information. An encoded image is usually divided into multiple macroblocks, which contain the luminance and chrominance information of each pixel. The main task of video decoding is to provide an efficient way to convert the code stream from the to obtain the pixel array in the macroblock.

Optionally, in some of the possible implementation manners, in 202, each anti-counterfeiting segment may be determined in the video frame as the macroblock sequence number of the macroblock carrying the skip run identifier. Correspondingly, after the anti-counterfeiting mark is split at 102 to obtain multiple anti-counterfeiting segments, alpha (α) channel conversion may also be performed on each anti-counterfeiting segment in the multiple anti-counterfeiting segments, and the α of each anti-counterfeiting segment can be converted into The channel is converted to a transparent background color. In 103 , according to the macroblock serial numbers of each anti-counterfeiting segment, insert the anti-counterfeiting segment as a newly added macroblock into a position determined based on the macroblock serial number of the anti-counterfeiting segment in the corresponding video frame.

Based on this embodiment, converting the alpha channel of the anti-counterfeiting segment to a transparent background color can prevent the information in the anti-counterfeiting segment from participating in video rendering during the subsequent video playback process, and will not change the overall video display screen, thereby preventing anti-counterfeiting. Data leakage will not affect the user's video viewing experience.

In a possible specific implementation manner, when inserting the anti-counterfeiting segment as a newly added macroblock into a position determined based on the macroblock sequence number of the anti-counterfeiting segment in the corresponding video frame, it is possible to first determine that the corresponding video carries the Whether the number of macroblocks identified by the skiprun is less than the macroblock sequence number M-1 of the anti-counterfeiting segment;

If the number of macroblocks carrying the skip run identifier in the corresponding video is less than M-1, then fill in the macroblocks carrying the skip run identifier in the video frame, so that the corresponding video carries the skip run identifier. The number of macroblocks is equal to M-1, and then, the anti-counterfeiting segment is inserted into the rear of the last macroblock carrying the skiprun mark in the corresponding video frame as a newly added macroblock;

Otherwise, if the number of macroblocks carrying the skip run identifier in the corresponding video is not less than M-1, insert the anti-counterfeiting segment as a newly added macroblock into the corresponding video frame based on the macroblock sequence number of the anti-counterfeiting segment determined location.

FIG. 6 is a schematic diagram of a macroblock structure of a video frame according to an embodiment of the present application. As shown in FIG. 6 , it is assumed that the macroblock sequence number of the anti-counterfeiting segment determined in this embodiment is 4, that is, the fourth macroblock in a video frame that carries the skip run identifier. There is only one macroblock carrying the skip run identifier, and two macroblocks carrying the skip run identifier can be supplemented (the second and third macroblocks carrying the skip run identifier in FIG. 6 ). The 2 macroblocks carrying the skip run logo in the same way do not carry other data, and then insert the anti-counterfeiting segment as the 4th newly added macroblock into the rear of the last macroblock carrying the skip run logo in the video frame, such as The fourth macroblock in FIG. 6 carries the skip run identifier.

Optionally, in some of the implementation manners, in 103, the plurality of anti-counterfeiting segments may be sequentially added to a plurality of consecutive video frames in the video. In this way, the anti-counterfeiting segment can be read frame by frame subsequently, which helps to improve the efficiency of reading the anti-counterfeiting segment data, thereby improving the identification efficiency of video piracy.

Optionally, in some of the implementation manners, in 103, the plurality of anti-counterfeiting segments may be added to each video frame in the video in sequence, wherein each video frame of the video is added with one Security section.

Based on this embodiment, even if a certain segment of the video is intercepted by other users or the head and tail of the video are removed, the first anti-counterfeiting segment and other non-forgery segments in the next cycle can still be read from the existing video frame. The first anti-counterfeiting segment, so that a complete anti-counterfeiting mark can be obtained to realize the piracy identification of the video.

Or, optionally, in other implementation manners, in 103, the plurality of anti-counterfeiting segments may also be added to part of the video frames in the video in a loop, wherein in one loop, the plurality of anti-counterfeiting segments The segments are sequentially added to a plurality of consecutive video frames in the video, and the video frames to which the anti-counterfeiting segment is added between different loops are adjacent or spaced by a certain video frame in a preset manner. That is, the multiple anti-counterfeiting segments may be sequentially added to multiple video frames of the video, and then the multiple anti-counterfeiting segments may be sequentially added to the next group of multiple video frames adjacent to the multiple video frames, The multiple anti-counterfeiting segments may also be sequentially added to multiple video frames after the multiple video frames are followed by several video frames, and each group of multiple video frames may be adjacent or spaced from the previous group of multiple video frames. several frames.

Based on this embodiment, even if a certain segment of the video is intercepted by other users or the head and tail of the video are removed, the first anti-counterfeiting segment and other non-forgery segments in the next cycle can still be read from the existing video frame. The first anti-counterfeiting segment can obtain a complete anti-counterfeiting mark and realize the identification of video piracy; and, since the anti-counterfeiting segment is not added to some video frames, the amount of data processing can be reduced and the processing efficiency of video anti-piracy can be improved.

In this way, pirated videos can be identified based on the anti-counterfeiting marks of each video, so as to effectively prevent videos from being pirated.

In addition, by adopting the technical solution provided by the present application, since the anti-counterfeiting mark of the video is divided into multiple anti-counterfeiting segments and added to different videos respectively, the whole video mark can be effectively prevented from being cracked when added in one video frame, which improves the performance of the video. Security of anti-counterfeiting marks to improve video anti-piracy effect.

In addition, with the technical solution provided by the present application, since the anti-counterfeiting mark of the video is divided into multiple anti-counterfeiting segments and added to different videos respectively, it can be avoided that the entire video mark is added in one video frame due to the data volume of the video mark. It is large and affects the smoothness of subsequent video playback, effectively ensuring the user's video viewing experience.

If the corresponding macroblock includes the sequence start identification information, the corresponding macroblock is determined to be the macroblock of the first anti-counterfeiting segment, and the first anti-counterfeiting segment is read from the macroblock of the first anti-counterfeiting segment. Anti-counterfeiting data, the number of anti-counterfeiting segments and the index information of the next segment. Otherwise, if the corresponding macroblock does not include the sequence start identification information, it is determined that the corresponding macroblock is not the macroblock of the first anti-counterfeiting segment, and the execution continues for the next video frame of the current video frame. The above operations are performed until it is determined that the corresponding macroblock is the macroblock of the first anti-counterfeiting section, and the first anti-counterfeiting data, the number of anti-counterfeiting sections and the next section index information are read from the macroblock of the first anti-counterfeiting section.

Based on this embodiment, based on multiple anti-counterfeiting segments being added to each video frame in the video repeatedly, even if a certain segment of the video is intercepted by other users or the head and tail of the video are removed, the video can still be retrieved from the video. In some video frames, the first anti-counterfeiting segment in the next cycle and other non-first anti-counterfeiting segments can be read, so that a complete anti-counterfeiting mark can be obtained to realize video piracy identification.

When reading the anti-counterfeiting data and the lower-section index information in the next anti-counterfeiting section from the video frame according to the lower-section index information in each anti-counterfeiting section, the skip can be carried in the video frame of the video according to the next anti-counterfeiting section The macroblock sequence number of the macroblock identified by run is read from the corresponding macroblock in the next video frame of the video frame where the first anti-counterfeiting segment is located, and the anti-counterfeiting data and lower-segment index information in the next anti-counterfeiting segment are read. Thus, the position of each anti-counterfeiting segment can be sequentially determined and the anti-counterfeiting data therein can be read.

For example, in one of the specific implementation solutions, it is assumed that the multiple anti-counterfeiting segments are specifically five anti-counterfeiting segments, and the positions of the five anti-counterfeiting segments in the video frame are: 23415, which means that the five anti-counterfeiting segments are in the video frame. The positions of the For the fifth macroblock identified by skip run, you can start from the first frame of the video and search frame by frame whether the second macroblock in the video frame includes sequence start identification information, until the second macroblock in a certain video frame is found. Each macroblock includes sequence start identification information, determine that the second macroblock is the macroblock of the first anti-counterfeiting segment, and read the first anti-counterfeiting data, the number of anti-counterfeiting segments, and the next segment index information (ie, the second macroblock) from the second macroblock. The index information of the second anti-counterfeiting segment: the third macroblock carrying the skip run identifier); then, the third macroblock carrying the skip run identifier in the next video frame is used as the macroblock of the second anti-counterfeiting segment, read The second anti-counterfeiting data, the number of anti-counterfeiting segments 5, and the index information of the lower segment (that is, the index information of the third anti-counterfeiting segment: the fourth macroblock carrying the skip run flag); ..., and so on, until 5 anti-counterfeiting pieces are read The anti-counterfeiting data of the segment can be spliced to obtain a complete anti-counterfeiting mark.

Optionally, in some implementation manners, in 703, if the anti-counterfeiting mark of the video is the same as the anti-counterfeiting mark of the target video, it may be confirmed that the video is a pirated video.

In this way, it is possible to identify whether the video is an anti-theft video, so as to effectively prevent the video from being pirated.
