In the embodiment of the application, the number of the anti-counterfeiting sections which can be detached for anti-counterfeiting is not limited, and the number can be 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 to 100 anti-counterfeiting segments, and a plurality of anti-counterfeiting segments are added to a video which can be played in a few seconds (e.g., 5 s).
103. Sequentially adding the plurality of anti-counterfeiting segments to a plurality of video frames of the video.
It should be noted that part or all of the execution subjects of 101 to 103 may be an application located in the terminal, or may also be a functional unit such as a plug-in or Software Development Kit (SDK) in the application that sets the terminal, or may also be an application located in a network side server, which is not particularly limited in this embodiment of the present application.
It is to be understood that the application may be a native app (native app) installed on the terminal, or may also be a web page app (webApp) of a browser on the terminal, which is not limited in this embodiment of the present application.
Therefore, a plurality of anti-counterfeiting segments can be extracted from different video frames of the video subsequently and spliced to obtain a complete anti-counterfeiting mark, so that piracy identification can be performed on the video based on the anti-counterfeiting mark, and the video can be effectively prevented from being pirated.
In addition, by adopting the technical scheme provided by the application, the video anti-counterfeiting mark is divided into a plurality of anti-counterfeiting segments which are respectively added into different videos, so that the situation that the whole video mark is added into one video frame and cracked can be effectively avoided, the safety of the anti-counterfeiting mark is improved, and the video anti-piracy effect is improved.
In addition, by adopting the technical scheme provided by the application, the video anti-counterfeiting mark is divided into the plurality of anti-counterfeiting sections which are respectively added into different videos, so that the influence on the fluency of subsequent video playing caused by the large data volume of the video mark when the whole video mark is added into one video frame can be avoided, and the video watching experience of a user is effectively ensured.
Fig. 2 is a schematic flow chart of obtaining a plurality of anti-counterfeiting segments by splitting the anti-counterfeiting mark in an embodiment of the present application. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, 102 may include:
201. and splitting the anti-counterfeiting mark into a plurality of parts to obtain a plurality of anti-counterfeiting data.
202. And respectively determining the positions of the anti-counterfeiting segments comprising the anti-counterfeiting data in the plurality of anti-counterfeiting data in the video frames.
203. And packaging a skip run identifier, sequence start identifier information, the number of corresponding anti-counterfeiting segments in the plurality of anti-counterfeiting data, the first anti-counterfeiting data and the lower segment index information to obtain the anti-counterfeiting segment of the first anti-counterfeiting data.
The sequence start identification information is used for identifying the start of the first anti-counterfeiting segment, and may be preset, for example, 1011; the lower segment index information is used for indicating the position of the next anti-counterfeiting segment in the video frame; the skip run flag is used to indicate that the corresponding data block is not to be played by the player.
204. And respectively packaging the skip run identifier, the number of the anti-counterfeiting segments, the anti-counterfeiting data and the lower segment index information aiming at other anti-counterfeiting data except the first anti-counterfeiting data and the last anti-counterfeiting data in the anti-counterfeiting data to obtain the anti-counterfeiting segments of the anti-counterfeiting data.
205. And packaging the skip run identifier, the number of the anti-counterfeiting segments and the last anti-counterfeiting data to obtain the anti-counterfeiting segment of the last anti-counterfeiting data.
It should be noted that there is no strict execution order limitation between the operations 203 to 205, and the operations may be executed in any order or simultaneously, and this embodiment of the present application only exemplarily shows a case of sequential execution.
Fig. 3 is a schematic diagram of a format of a security segment of first security data in an embodiment of the present application. The anti-counterfeiting segment of the non-first anti-counterfeiting data does not comprise sequence starting identification information relative to the anti-counterfeiting segment of the first anti-counterfeiting data, and the anti-counterfeiting segment of the last anti-counterfeiting data does not comprise lower segment index information relative to the anti-counterfeiting segments of other non-first anti-counterfeiting data. The sequence of the data included in each anti-counterfeiting segment can be adjusted, and is not limited to the sequence in the embodiment shown in fig. 3.
Based on this embodiment, after determining the position of each anti-counterfeiting segment in the video frame, the position index (lower segment index information) of the next anti-counterfeiting segment can be carried sequentially by the previous anti-counterfeiting segment, so that only after determining the position of the first anti-counterfeiting segment in the video frame and reading the lower segment index information in the first anti-counterfeiting segment, the anti-counterfeiting data in the next adjacent anti-counterfeiting segment and the lower segment index information in the next adjacent anti-counterfeiting segment can be read sequentially, and so on, thereby improving the security of the anti-counterfeiting data, and further improving the security of the whole anti-counterfeiting mark. In addition, the data block comprising the anti-counterfeiting segment carries the skip run identifier, so that the data block cannot be played by the player, and the video playing effect cannot be influenced.
Fig. 4 is a schematic diagram of a correspondence between a video frame and an anti-counterfeit section according to an embodiment of the present application.
Fig. 5 is a schematic flowchart illustrating a process of determining the position of each anti-counterfeit segment in a video frame according to an embodiment of the present application. As shown in fig. 5, on the basis of the embodiment shown in fig. 2, 202 may include:
501. and mapping the anti-counterfeiting mark to a numerical value within a specified numerical value interval range based on a preset hash algorithm.
The range of the designated value interval may be determined according to a specific video coding standard and a frame format, for example, in one embodiment, the range of the designated value interval may be 1 to 5. The embodiment of the present application does not limit the specific values in the range of the designated numerical value interval.
502. And taking the value as the position of the first anti-counterfeiting segment in the video frame.
503. And determining the positions of other non-first anti-counterfeiting segments in the video frame according to a preset mode.
Based on the embodiment, the anti-counterfeiting mark is mapped to a numerical value within a specified numerical value range based on a preset hash algorithm to serve as the position of the first anti-counterfeiting segment in the video frame, so that the safety of the position of the first anti-counterfeiting segment can be improved, and the anti-counterfeiting mark is not easy to crack and erase, so that the positions of other non-first anti-counterfeiting segments cannot be determined and data cannot be read, the safety of the whole anti-counterfeiting mark is improved, and the anti-counterfeiting mark is not easy to remove.
Optionally, in some possible implementation manners, in 503, a value may be randomly determined within the range of the specified value interval as the position of each of the other anti-counterfeiting segments in the video frame, that is, the position of each of the other anti-counterfeiting segments in the video frame may be randomly determined, so that the positions of the other anti-counterfeiting segments in the video frame are random and are not easy to be determined and read, and the security of the anti-counterfeiting segment information may be improved, thereby improving the security of the anti-counterfeiting mark.
Or, in some possible implementation manners, in 503, the position of the next anti-counterfeiting segment in the video frame may also be determined sequentially according to the position of each anti-counterfeiting segment in the multiple anti-counterfeiting data in the video frame and a preset rule, where the preset rule may be determined according to an actual situation, for example, in one embodiment, the position of each anti-counterfeiting segment in the video frame may be gradually decreased by 1 or increased by 1 as the position of the next anti-counterfeiting segment in the video frame, or a preset function may 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, and a specific manner of the preset rule is not limited in the embodiment of the present application. Therefore, the position of the next anti-counterfeiting segment in the video frame needs to be determined based on the position of each anti-counterfeiting segment in the video frame and the preset rule, and under the condition that the preset rule cannot be obtained, the position of the next anti-counterfeiting segment in the video frame cannot be determined, so that the anti-counterfeiting data in the next anti-counterfeiting segment is prevented from being read, the safety of the information of the anti-counterfeiting segment can be improved, and the safety of the anti-counterfeiting mark is improved.
The embodiment of the application can be applied to video with any format and video coding standard. In a particular implementation, each anti-counterfeiting segment can be inserted into a corresponding location in a video frame.
For example, in the h.264/AVC video coding standard, the original bitstream (naked stream) is composed of Network Abstraction Layer Units (NALUs) one by one, and the whole system framework is divided into two layers: video Coding Layer (VCL) and Network Abstraction Layer (NAL). Among them, an original NALU is often composed of three parts, a start code (StartCode), a NALU Header (NALU Header), and a NALU Payload (NALU Payload), wherein the NALU Payload is the body of the NALU. The NALU body includes a slice header and slice data, and 1 frame is n slices (slice), 1 slice is n Macroblocks (MB), and 1 macroblock is 16 × 16yuv data. The macro block is a main carrier of video information, a coded image is usually divided into a plurality of macro blocks, which contain luminance and chrominance information of each pixel, and the most important task of video decoding is to provide an efficient way to obtain a pixel array in the macro block from a code stream.
Optionally, in some possible implementations, in 202, the macroblock sequence number of each anti-fake segment in the video frame as the macroblock carrying the skip run identifier may be determined respectively. Correspondingly, after the anti-counterfeiting mark is split at 102 to obtain a plurality of anti-counterfeiting segments, alpha (α) channel conversion can be performed on each anti-counterfeiting segment in the plurality of anti-counterfeiting segments, and an α channel of each anti-counterfeiting segment is converted into a transparent background color. In 103, the anti-counterfeiting segment is inserted into a position determined based on the macro block number of the anti-counterfeiting segment in the corresponding video frame as a newly added macro block according to the macro block number of each anti-counterfeiting segment.
Based on the embodiment, the alpha channel of the anti-counterfeiting segment is converted into the transparent background color, so that the information in the anti-counterfeiting segment does not participate in video rendering in the subsequent video playing process, the picture displayed by the whole video is not changed, and therefore the anti-counterfeiting data cannot be leaked, and the video watching experience of a user cannot be influenced.
In a possible specific implementation manner, when the anti-counterfeiting segment is inserted into a position, which is determined based on the macro block serial number of the anti-counterfeiting segment, of a corresponding video frame as a newly added macro block, it may be determined whether the number of macro blocks carrying the skip run identifier in the corresponding video is smaller than the macro block serial number M-1 of the anti-counterfeiting segment;
if the number of macro blocks carrying the skip run identifier in the corresponding video is less than M-1, supplementing the macro blocks carrying the skip run identifier in the video frame, so that the number of the macro blocks carrying the skip run identifier in the corresponding video is equal to M-1, and then inserting the anti-counterfeiting segment serving as a newly added macro block into the rear part of the last macro block carrying the skip run identifier in the corresponding video frame;
otherwise, if the number of the macro blocks carrying the skip run identifier in the corresponding video is not less than M-1, inserting the anti-counterfeiting segment as a newly added macro block into a position determined based on the macro block sequence number of the anti-counterfeiting segment in the corresponding video frame.
Fig. 6 is a schematic diagram illustrating 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 macro block sequence number of the anti-counterfeit segment determined in this embodiment is 4, that is, the 4 th macro block carrying the skip run identifier in one video frame, at this time, since only 1 macro block carrying the skip run identifier in the video frame may be supplemented with 2 macro blocks carrying the skip run identifier (e.g., the 2 nd and 3 rd macro blocks carrying the skip run identifier in fig. 6), the supplemented 2 macro blocks carrying the skip run identifier do not carry other data, and then the anti-counterfeit segment is inserted as the 4 th newly added macro block into the rear portion of the last macro block carrying the skip run identifier in the video frame, for example, the 4 th macro block carrying the skip run identifier in fig. 6.
Optionally, in some of the implementations, the plurality of anti-counterfeiting segments may be sequentially added to a plurality of consecutive video frames in the video in 103. Therefore, the anti-counterfeiting segment can be read frame by frame subsequently, the efficiency of reading the anti-counterfeiting segment is improved, and the identification efficiency of video piracy is improved.
Optionally, in some of the implementation manners, in 103, the multiple anti-counterfeiting segments may be sequentially and cyclically added to video frames in the video, where one anti-counterfeiting segment is added to each video frame in the video.
Based on the embodiment, even if the video is intercepted by other users or the head and the tail of the video are removed, the first anti-counterfeiting segment and other non-first anti-counterfeiting segments in the next cycle can be read from the existing video frame, so that a complete anti-counterfeiting mark can be obtained, and the pirate identification of the video is realized.
Or optionally, in another implementation manner, in 103, the multiple anti-counterfeiting segments may also be sequentially added to part of the video frames in the video in a circulating manner, where the multiple anti-counterfeiting segments are sequentially added to multiple consecutive video frames in the video in one circulating manner, and the video frames with the anti-counterfeiting segments added in different circulating manners are adjacent to each other or are separated by a certain video frame according to a preset manner. That is, the anti-counterfeiting segments may be sequentially added to a plurality of video frames of a video, and then the anti-counterfeiting segments may be sequentially added to a next plurality of video frames that are next and adjacent to the plurality of video frames, or the anti-counterfeiting segments may be sequentially added to a plurality of video frames that are next and adjacent to the plurality of video frames after a plurality of video frames are separated, and each of the plurality of video frames and the previous plurality of video frames may be adjacent to each other or separated by a plurality of frames.
Based on the embodiment, even if the video is intercepted by other users or the head and the tail of the video are removed, the first anti-counterfeiting segment and other non-first anti-counterfeiting segments in the next cycle can still be read from the existing video frame, so that a complete anti-counterfeiting mark can be obtained, and the pirate identification of the video is realized; moreover, as the anti-counterfeiting segment is not added in part of the video frames, the data processing amount can be reduced, and the processing efficiency of video anti-piracy is improved.

702. And splicing the extracted anti-counterfeiting sections to obtain the anti-counterfeiting mark of the video.
703. And carrying out piracy identification on the video based on the anti-counterfeiting mark.
It should be noted that part or all of the execution subjects 701 to 703 may be an application (e.g., a player) located in the terminal, or may also be a functional unit such as a plug-in or a Software Development Kit (SDK) in an application configured in the terminal, or may also be an application located in a network side server (e.g., a video platform or a self-media platform), which is not particularly limited in this embodiment of the present application.
It is to be understood that the application may be a native app (native app) installed on the terminal, or may also be a web page app (webApp) of a browser on the terminal, which is not limited in this embodiment of the present application.
In this way, pirated videos can be identified based on the anti-counterfeiting mark of each video, so that the videos can be effectively prevented from being pirated.
In addition, by adopting the technical scheme provided by the application, the video anti-counterfeiting mark is split into a plurality of anti-counterfeiting segments which are respectively added into different videos, so that the whole video mark can be effectively prevented from being cracked when being added into one video frame, the safety of the anti-counterfeiting mark is improved, and the video anti-piracy effect is improved.
In addition, by adopting the technical scheme provided by the application, the video anti-counterfeiting mark is divided into the plurality of anti-counterfeiting sections which are respectively added into different videos, so that the influence on the fluency of subsequent video playing caused by the large data volume of the video mark when the whole video mark is added into one video frame can be avoided, and the video watching experience of a user is effectively ensured.
Fig. 8 is a schematic flow chart illustrating a process of extracting anti-counterfeit segments from multiple video frames of a video to obtain multiple anti-counterfeit segments according to another embodiment of the present application. As shown in fig. 8, on the basis of the embodiment shown in fig. 7, 701 may include:
801. and determining the position of a first anti-counterfeiting segment in the anti-counterfeiting segments in the video frame of the video based on the anti-counterfeiting mark of the target video similar to the video, and reading the first anti-counterfeiting data, the number of the anti-counterfeiting segments and the lower segment index information in the first anti-counterfeiting segment according to the position of the first anti-counterfeiting segment in the video frame of the video.

And sequentially 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 until the anti-counterfeiting data in all the anti-counterfeiting sections in the plurality of anti-counterfeiting sections are read according to the number of the anti-counterfeiting sections.
Accordingly, in this embodiment, in 702, the anti-counterfeiting data in the multiple anti-counterfeiting segments may be sequentially spliced to obtain the anti-counterfeiting mark of the video.
Based on the embodiment, the position of the first anti-counterfeiting segment in the multiple anti-counterfeiting segments in the video frame of the video is determined based on the anti-counterfeiting mark of the target video, the first anti-counterfeiting data, the number of the anti-counterfeiting segments and the lower segment index information in the first anti-counterfeiting segment are read, the anti-counterfeiting data and the lower segment index information in the next anti-counterfeiting segment are read from the video frame in sequence according to the lower segment index information in each anti-counterfeiting segment until the anti-counterfeiting data in all the anti-counterfeiting segments in the multiple anti-counterfeiting segments are read, and therefore the anti-counterfeiting mark of the video is spliced to carry out piracy identification on the video, so that the safety of the anti-counterfeiting data is improved, and the safety of the whole anti-counterfeiting mark is improved.
In the embodiment shown in fig. 8, if the position of each anti-counterfeiting segment in the video frame of the video cannot be read, the anti-counterfeiting data therein cannot be read, and it can be determined that the video is different from the anti-counterfeiting mark of the target video in the case that the video is seriously damaged and does not carry any first anti-counterfeiting segment or not completely carry all anti-counterfeiting segments of the plurality of anti-counterfeiting segments, and the video is not a pirated video of the target video.
Optionally, in some implementations, in 801, the anti-counterfeit mark of the target video may be mapped to a value within a specified range of values based on a preset hash algorithm, and then the value is used as the position of the first anti-counterfeit segment in the video frame of the video.
Based on the embodiment, the anti-counterfeiting mark is mapped to a numerical value within a specified numerical value range based on a preset hash algorithm to serve as the position of the first anti-counterfeiting segment in the video frame, so that the safety of the position of the first anti-counterfeiting segment can be improved, and the anti-counterfeiting mark is not easy to crack and erase, so that the positions of other non-first anti-counterfeiting segments cannot be determined and data cannot be read, the safety of the whole anti-counterfeiting mark is improved, and the anti-counterfeiting mark is not easy to remove.
In some possible implementations, the location in a video frame of the video may include: and taking the sequence number of the macro block carrying the skip run identifier in the video frame of the video.
Correspondingly, when the first anti-counterfeiting data, the number of the anti-counterfeiting segments and the lower segment index information in the first anti-counterfeiting segment are read according to the position of the first anti-counterfeiting segment in the video frame of the video, the macro block sequence number of the macro block carrying the skip run identifier in the video frame of the video can be read according to the first anti-counterfeiting segment, one video frame in the video is sequentially used as the current video frame, the corresponding macro block is read from the current video, and whether the corresponding macro block comprises sequence start identifier information or not is identified, wherein the sequence start identifier information is used for identifying the start of the first anti-counterfeiting segment.

Therefore, the positions of the anti-counterfeiting segments can be determined in sequence to read the anti-counterfeiting data in the anti-counterfeiting segments.
For example, in one specific implementation scheme, it is assumed that the multiple anti-counterfeiting segments are specifically 5 anti-counterfeiting segments, and the positions of the 5 anti-counterfeiting segments in the video frame are: 23415, the positions of the 5 anti-counterfeiting segments in the video frame are: a 2 nd macro block carrying a skip run identifier, a 3 rd macro block carrying a skip run identifier, a 4 th macro block carrying a skip run identifier, a 1 st macro block carrying a skip run identifier, and a 5 th macro block carrying a skip run identifier, wherein from a first frame of a video, whether the 2 nd macro block in the video frame includes sequence start identifier information or not can be searched frame by frame until the 2 nd macro block in a certain video frame includes the sequence start identifier information, the 2 nd macro block is determined to be a macro block of a first anti-counterfeiting segment, and the first anti-counterfeiting data, the number of anti-counterfeiting segments 5 and lower segment index information (namely index information of the 2 nd anti-counterfeiting segment: the 3 rd macro block carrying the skip run identifier) are read from the 2 nd macro block; then, taking the 3 rd macro block carrying the skip run mark in the next video frame as the macro block of the 2 nd anti-counterfeiting segment, and reading the 2 nd anti-counterfeiting data, the anti-counterfeiting segment quantity 5 and the lower segment index information (namely the index information of the 3 rd anti-counterfeiting segment: the 4 th macro block carrying the skip run mark); …, repeating the above steps until 5 anti-counterfeiting data of the anti-counterfeiting segments are read, and splicing to obtain the complete anti-counterfeiting mark.
Optionally, in some implementation manners, in 703, if the anti-counterfeit mark of the video is the same as the anti-counterfeit mark of the target video, it may be determined that the video is a pirated video.
Therefore, the video is identified whether to be the anti-theft video or not, and the video is effectively prevented from being pirated.
