Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
The invention provides a video playing method, which is applied to terminal equipment, wherein the terminal equipment is in communication connection with a data server.
As shown in fig. 1, in one embodiment, the video playing method includes the following steps:
step 101: and sending a playing request for playing the target video to the data server.
In this embodiment, the video data is stored in the data server, and when the user needs to watch a certain video, for example, click an icon of a target video in an application program on the terminal device, a manner of sending a play request to the data server by the terminal device is not limited thereto, and reference may be made to related technologies, which are not further limited and described herein.
Step 102: and receiving video data and a unique traceable watermark sent by the data server in response to the playing request, wherein the traceable watermark comprises a plurality of watermark images arranged in a specific sequence.
The tracing watermark in this embodiment has uniqueness and includes tracing information, and the tracing watermark includes a plurality of watermark images arranged in a specific order. The source tracing watermark may be a unique code, for example, a unique code is generated when the server does not receive a play request, so that the relevant information of the corresponding play request may be indexed according to the code to determine the relevant information corresponding to the play request.
In an optional embodiment, the source-tracing watermark is generated according to relevant data of the terminal device and is associated with the terminal device, for example, the model of the terminal device, the user information corresponding to the terminal device, the internet protocol address (IP address) of the terminal device, and one or more of the playing time of the target video are included. By recording the data in the traceability information, the source and the way of the pirate can be conveniently and quickly determined.
For example, in one embodiment, the tracing watermark includes two different patterns of watermark images, the tracing information is in the form of binary data, and each pattern of the watermark images corresponds to one type of the binary data.
In particular, in practice, the tracing information is a set of binary data, for example, a 16-bit binary data 0101000011101100.
The traceable watermark comprises two watermark images in different patterns, specifically, different colors and different shapes. The watermark image of each style corresponds to one kind of binary data, and the binary data only comprises 1 and 0 digits, so that the tracing watermark can be converted into the corresponding binary data after the corresponding relation between the watermark image and the digits is determined, and the tracing watermark can be converted into tracing information and further analyzed to obtain specific content included in the tracing information.
The pattern of the watermark image may be distinguished by means including, but not limited to, color, shape, and the like. For example, in one embodiment, two watermark images, image a and image B, are included, where image a is a red watermark image and corresponds to a 1 in the binary data, and image B is a green watermark image and corresponds to a 0 in the binary data; for another example, in a specific embodiment, the watermark image includes two watermark images, namely an image a and an image B, where the image a is three pixels arranged in a triangle and corresponds to 1, and the image B is four pixels arranged in a quadrilateral and corresponds to 0.
Taking the example that two watermark images including image a and image B, image a corresponds to 1 and image B corresponds to 0, a group of watermark images, image a, image B, image a, image B, image a, represents binary digits 10110011.
Further, the binary data needs to be analyzed to obtain the model of the terminal device, the user information corresponding to the terminal device, the IP address, the playing time of the target video, and other contents.
In a specific embodiment, the meaning represented by the tracing information can be obtained by establishing an index information table, and taking the model of the terminal device as an example, in implementation, an information table including devices of various models can be established, wherein each device corresponds to a unique number, and the number is in a binary format. The specific digits in the trace information represent the device number, for example, the trace information is for including 16 digits, wherein the first four digits represent the device number. After the tracing information is obtained, searching is carried out in the information table according to the first four digits, and the model of the equipment can be determined according to the searching result.
Different information tables can be established by referring to the method aiming at other contents included in the tracing information, so that the tracing information can be analyzed according to the tracing watermark in the unauthorized recorded video, and the contents included in the tracing information can be further obtained through indexing.
Therefore, other people cannot acquire the information table, so that specific content included in the information table cannot be acquired, the tracing information contained in the tracing image can be more concealed, and the possibility of being discovered by other people is reduced.
Step 103: embedding the plurality of watermark images into the target video, wherein each frame of image in the target video comprises at most one watermark image.
Furthermore, the set of numbers is embedded into each frame image in the video data in sequence according to the playing order of the plurality of frame images. The tracing information included in the tracing watermark can completely record the related data of video playing, so as to form strong evidence.
Embedding of the traceable watermark can be embedded into the video in a common overlapping embedding mode, namely, an image of the traceable watermark is exposed at a certain position of the video, and the embedding can also be hidden, so that the concealment is improved, and the hidden embedding technology can refer to related technologies, and is not further limited and described here.
In implementation, at most 1 watermark image is embedded in each frame of image, for example, the generated traceable watermark is a binary digit 0101000011101100 with 16 bits, the corresponding watermark image sequence can be further determined to be image B, image a, image B, image a, image B, image a, image B, and image B, further, 16 frames of images are selected, and the 16 watermark images are sequentially embedded into the 16 frames of images according to the playing sequence, that is, the traceable watermark is embedded into the video data of the target video.
It should be understood that, in order to improve the embedding effect of the traceable watermark, the traceable watermark may be embedded in the target video in a plurality of cycles, for example, the embedding of the traceable watermark is performed every 1 second or every 10 seconds in the video, and obviously, the embedding time interval in the practical implementation is not limited thereto, so that even if the video is cut out of a part, the possibility of the traceable watermark existing in the video can be improved.
Furthermore, the embedding position of the tracing watermark can be adjusted, for example, the tracing watermark is embedded in the upper right corner of the video for the first time, the tracing watermark is embedded in the upper left corner of the video for the second time, and the tracing watermark is embedded in the central position of the video for the third time, so that the possibility of the tracing watermark being lost due to the fact that the local part of the video is shielded through a mosaic and the like can be reduced.
Step 104: and playing the target video embedded with the tracing watermark.
And finally, playing the target video embedded with the tracing watermark, wherein if the video is stolen and recorded in the playing process, the stolen and recorded video also carries the corresponding tracing watermark, and the related information of video playing can be determined by extracting the tracing watermark and analyzing tracing information included in the tracing watermark, so that the source and the path of the stolen and recorded video are determined.
According to the embodiment of the invention, the tracing watermark containing the tracing information is embedded into the video data, when the stolen video occurs, the tracing of the stealing path can be carried out through the tracing watermark contained in the stolen video, and meanwhile, because the tracing watermark is formed by the watermark images embedded into the multi-frame images together, the possibility that the watermark images are shielded or removed can be reduced, thereby being beneficial to improving the tracing of the stealing path and the source of the stolen video.
The invention also provides a video playing control method, which is applied to the data server, and the data server is in communication connection with the terminal equipment.
As shown in fig. 2, in one embodiment, the video playback control method includes the following steps:
step 201: and receiving a playing request for playing the target video sent by the terminal equipment.
Step 202: and generating a unique traceable watermark according to the playing request, wherein the traceable watermark comprises a plurality of watermark images arranged according to a specific sequence.
Step 203: and sending the source tracing watermark and the video data of the target video to the terminal equipment so that the terminal equipment can embed the watermark images into the target video, wherein each frame image in the target video comprises at most one watermark image.
In the technical solution of this embodiment, after receiving a play request from a terminal device, a data server generates a corresponding source-tracing watermark, and sends the source-tracing watermark and video data to the terminal device, where the generated source-tracing watermark may refer to the above video play method embodiment specifically, and a process of sending video data may refer to a related technology, which is not described herein again.
According to the embodiment of the invention, the tracing watermark containing the tracing information is embedded into the video data, when the stolen video occurs, the tracing of the stealing path can be carried out through the tracing watermark contained in the stolen video, and meanwhile, because the tracing watermark is formed by the watermark images embedded into the multi-frame images together, the possibility that the watermark images are shielded or removed can be reduced, thereby being beneficial to improving the tracing of the stealing path and the source of the stolen video.
As shown in fig. 3, the technical solution of the present invention may be summarized as that, first, a terminal device performing video playing sends a playing request for playing a video to a data server, and the data server generates a tracing watermark after receiving the playing request, and if necessary, may also generate an information table associated with the tracing watermark, and other related information, where the information table refers to an information table used for indexing according to tracing information in the tracing watermark in the above embodiment, and the tracing watermark may directly represent information related to the playing request, or may be only used as an index number to perform related indexing in a specific information table.
Further, the data server sends the video data and the generated tracing watermark to the terminal device, specifically, the sequence may be a video playing address and a watermark image, so that the terminal device adds the tracing watermark to the video and plays the video.
Therefore, if the video is not authorized to be recorded through a screen recording or by utilizing a photographic device, the traceable watermark is contained in the recorded video, and the source of the video can be determined by extracting the traceable watermark in the video and further analyzing the traceable information contained in the traceable watermark.
