Based on the above system, embodiments of the present application provide a video data protection method, which is described below with reference to a plurality of embodiments.
Example one
Referring to fig. 2A, a flowchart illustrating steps of a video data protection method according to a first embodiment of the present application is shown.
The video data protection method of the present embodiment is explained from the viewpoint of video production protection, and the video data protection method of the present embodiment includes the following steps:
step S202: and acquiring the video to be embedded with the authentication information and the authentication information to be embedded.
For most video creators, it is generally desirable to protect the video after the video is created, for example, the video can be protected by the authentication information, and such video can be used as the video to be embedded with the authentication information in the embodiment of the present application.
The authentication information may be set by a person skilled in the art according to actual situations, such as user information that may be a video creator, or information related to rights or identities that needs to be added for the video creator, and the like, which is not limited in the embodiments of the present application.
Step S204: and performing digital watermarking processing based on the frequency domain on the video according to the authentication information to obtain the video embedded with the frequency domain digital watermark.
Digital watermarking in the frequency domain refers to transforming an image into the frequency domain (wavelet domain) by some transformation means (for example, fourier transform, discrete cosine transform, wavelet transform, etc.), watermarking the image in the frequency domain, and transforming the image into a spatial domain by inverse transformation. The frequency domain digital watermark has stronger hiding performance and higher attack resistance.
Step S206: and performing space domain digital watermarking processing based on a preset quantization threshold value on the video embedded with the frequency domain digital watermark to obtain an authentication video embedded with the space domain digital watermark.
As described above, in the embodiment of the present application, after the video is embedded with the frequency domain digital watermark through the video frame image, the spatial domain digital watermark processing is performed again to further improve the attack resistance of the video.
Specifically, in the embodiment of the present application, spatial domain watermarking based on a preset quantization threshold is performed on a video. The quantization threshold is used to define a range that allows the pixel values of the image to fluctuate, which subsequently allows the original watermark data to be recovered at larger pixel brightness variations. The specific value of the quantization threshold may be set according to the video frame image or empirical value or data statistics or simulation test result, and may be set to 3, for example.
In this step, for the video frame image embedded with the frequency domain digital watermark, quantization processing may be performed on the video frame image by using a quantization threshold, authentication information is added to a result based on the quantization processing, and then a reverse process of the quantization processing is performed to obtain a new video frame image. And obtaining the video embedded with the spatial domain digital watermark again based on all the processed video frame images, namely the authentication video. Therefore, the video is protected, and meanwhile the video has better anti-interference performance for image change.
Therefore, the effective and active protection of the original video of the video creator can be realized through the process. However, in order to further improve the protection effect, in an optional manner, after the authentication video is obtained, a data block may be generated according to the authentication video and the authentication information, the data block is added into the block chain for authentication and verification, and an authentication and verification result of the data block in the block chain is obtained.
From the application perspective, the blockchain is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace leaving in the whole process, traceability, collective maintenance, openness and transparency and the like. The characteristics ensure the honesty and the transparency of the block chain and lay a foundation for creating trust for the block chain. The blocks are one storage unit, and all communication information of each block node within a certain time is recorded. The blocks are linked through random hashing (also called hashing algorithm), the next block contains the hash value of the previous block, and as the information communication expands, one block is connected with one block in sequence to form a block chain.
When the block chain is used for protecting the video works, the authentication video and the authentication information obtained after the watermarking is performed twice can be generated into a block to be added into the block chain for storing the certificate, so that an authentication and certificate storing result is obtained. On one hand, the authentication and evidence storage result can be sent to the client device for the video creator to store; on the other hand, the authentication result can provide basis for subsequently judging whether a certain video is an original video or not or whether the video infringes.
The above process is exemplified below with a specific scenario example, as shown in fig. 2B.
In fig. 2B, it is assumed that user X has authored a short video a through a video authoring and production platform in his client device, through which copyright protection is requested. The client device triggers video protection operation through corresponding settings in the platform, such as a 'request protection' button; the client equipment obtains the user information of the user X according to the triggering operation, generates and sends a video protection request to the video creation production platform server equipment through a video creation production platform in the client equipment; after receiving the request, the server side equipment acquires the user information of the short video A and the user X from the client side equipment, and takes the user information of the user X as authentication information; further, embedding a hidden digital watermark in a frequency domain for a video frame image in the short video A through a DCT (discrete cosine transform) algorithm based on the authentication information; on the basis, the video frame image is transformed into a space domain, quantization processing based on a quantization threshold value K is firstly carried out on the video frame image in the space domain, authentication information is added after the quantization processing, and therefore the video frame image added with the space domain digital watermark again is generated, and the authentication video A' can be obtained based on the video frame images; then, the server side equipment generates a data block from the authentication video A' and the user information of the user X; then, the data block is added into a block chain, in this example, a alliance chain, to perform authentication and storage, and an authentication and storage result of the authentication and storage is returned to the client device.
Therefore, according to the embodiment, the hidden digital watermark embedded in the video can be formed by performing watermark processing twice on the original video work of the video creator, and then the video and the digital watermark are authenticated and stored by using the block chain technology, so that whether the video is original or not can be effectively identified subsequently. When the video is subjected to watermarking, the video is firstly subjected to frequency domain watermarking, so that the protection of a first-level hidden watermark can be realized, but in order to enable the video to have stronger attack resistance, a second-level spatial domain watermarking is added for the video on the basis of the frequency domain watermarking, and the spatial domain watermarking is performed on the basis of a quantization threshold value. Therefore, the video is stronger in attack resistance, and better in anti-interference performance on image change. Therefore, through the scheme of the embodiment of the application, effective and active video work protection is achieved.
In addition, if the video and the digital watermark are added into the block chain on the basis of adding the digital watermark, the generated authentication deposit certificate can effectively prove the identity of the video original author due to the originality and the safety of data in the block chain, so that the proof is provided for the copyright protection of the video, and the rights and interests of the original author are further guaranteed. Therefore, the effect of protecting the video works is further improved.
Example two
Referring to fig. 3A, a flowchart illustrating steps of a video data protection method according to a second embodiment of the present application is shown.
The video data protection method of this embodiment is still described from the viewpoint of video production protection, and the video data protection method of this embodiment includes the following steps:
step S302: and acquiring the video to be embedded with the authentication information and the authentication information to be embedded.
As described above, the video to be embedded with the authentication information in the embodiment of the present application is generally an original video. In a feasible manner, the video data protection scheme provided by the embodiment of the present application can be integrated in a video creation production platform, so as to be conveniently used by a video creator and improve the efficiency of video data protection. Based on this, in this step, a video protection request triggered after the video creation is completed by the video creation production platform client can be received; acquiring user information of a video creator and a created video from the user client according to the request; and taking the created video as the video to be embedded with the authentication information, and generating the authentication information to be embedded according to the user information. In practical applications, the user information may be directly used as the authentication information, but is not limited thereto, and other information may be added or the user information may be modified, such as encrypted, based on the user information and then used as the authentication information, so as to further protect the privacy information of the video creator.
Step S304: and performing digital watermarking processing based on the frequency domain on the video according to the authentication information to obtain the video embedded with the frequency domain digital watermark.
There are various ways of frequency domain digital watermarking, including but not limited to frequency domain digital watermarking algorithm based on fourier transform, frequency domain digital watermarking algorithm based on discrete cosine transform, frequency domain digital watermarking algorithm based on wavelet transform, etc. In an exemplary manner of the embodiment, the binary form of the authentication information may be encoded by a Reed-solomon codes method to improve the error correction capability, and then the encoding is embedded into each frame image of the video by a DCT-based frequency domain digital watermarking algorithm. Among them, the Reed-solomon codes method is an error control coding method which improves the error correction capability of the code by adding some redundancy codes after the data of the galois field. Therefore, the authentication information also has better error correction capability.
In addition, as an optional implementation manner, in this embodiment, when performing frequency domain digital watermarking on a video, a video frame image of the video may be first transformed into a frequency domain; and adding authentication information to a fixed area of the video frame image in the frequency domain, wherein the fixed area is a corner area and/or a central area of the video frame image. On one hand, the area of the image region needing to be calculated is greatly reduced, the calculation efficiency of frequency domain embedding and extraction is greatly improved, and the real-time interaction requirement of a user can be met; on the other hand, due to the relationship between the corners (e.g., four corners) and the specific positions of the central region, the frequency domain embedding has attack resistance to frequency domain attack methods such as luminance variation, noise addition, filter addition, image compression, video encoding and decoding, and the like, and also has attack resistance to spatial domain attack methods that retain one-sided clipping of one of the four corners and center clipping of the central region.
The fixed area is a square with the side length of N, and the N is determined according to the length of the authentication information and the size of the DCT window. Therefore, the integrity of the authentication information is guaranteed, and the authentication information can be effectively processed.
In one example, frequency domain digital watermark embedding is performed in a fixed partial area of a video frame image. Specifically, a plurality of fixed regions may be selected from the video frame image for frequency domain digital watermark embedding, for example, the selected region is a square with a side length of N, and the positions of the selected region include an upper left corner, a lower left corner, an upper right corner, a lower right corner, and a middle of the image. Where N ═ sqrt (M) × w, M indicates the authentication information length such as 256, sqrt indicates square root formation, and w is the DCT window size, and is typically 2.
Through the process, the embedding of the frequency domain digital watermark of the video can be realized, and the watermark is a hidden watermark.
Step S306: and performing space domain digital watermarking processing based on a preset quantization threshold value on the video embedded with the frequency domain digital watermark to obtain an authentication video embedded with the space domain digital watermark.
For example, the above-described code obtained by the Reed-solomon codes method is embedded into each frame image of the video again by the spatial domain digital watermarking algorithm based on LSB (least significant bit).
Different from the traditional spatial domain digital watermarking, the spatial domain digital watermarking on the video is realized based on a preset quantization threshold value in the embodiment of the application.
When the step is specifically realized, for the video frame image in the video embedded with the frequency domain digital watermark, acquiring component values of all colors of a color space model corresponding to the video frame image; quantizing the component values by using a quantization threshold value, and embedding authentication information on the basis of the quantized component values; and updating the video frame image according to the component value embedded with the authentication information to obtain the authentication video embedded with the spatial domain digital watermark. Optionally, when the video frame image is updated according to the component value embedded with the authentication information to obtain the authentication video embedded with the spatial domain digital watermark, a reverse vectorization process may be performed on the component value embedded with the authentication information to obtain a reverse vectorization result; and updating the video frame image by using the inverse quantization result to obtain the authentication video embedded with the spatial domain digital watermark. Wherein the quantization threshold may be determined according to an acceptable color fluctuation range of a video frame image of the video.
Color space models for images include, but are not limited to: an RGB color space model, an RGBA color space model, a YUV color space model, an HSV color space model, etc. In this embodiment, the RGB color space model is selected, which has wide versatility, easy processing, and low data processing cost. It will be apparent to those skilled in the art that, regardless of the color space model used, the quantization threshold-based processing of its color components may be such that the original watermark information is recovered even under image brightness variations.
In a specific example, a quantization threshold K is set, and for three channel values R, G, B of a pixel point in a video frame image, the quantization threshold K is used to quantize the three channel values
Then, on the basis of the quantized values r, g and b, embedding watermark data (authentication information) of one bit at the same time to obtain new values r ', g ' and b '; then, the inverse process of quantization is performed to obtain
Then, the corresponding pixel points in the video frame image are updated according to the pixel values R ', G ' and B '.
The effect of K is to set a range of allowable fluctuation of the pixel value, so as to allow recovery of the original watermark information under a larger variation of the pixel brightness, and K may be set to 3 alternatively.
Therefore, the method and the device realize the double hidden digital watermarking of the frequency domain and the space domain of the video, and obtain the authentication video.
Step S308: and generating a data block according to the authentication video and the authentication information, adding the data block into a block chain to perform authentication and evidence storage, and obtaining an authentication and evidence storage result of the data block in the block chain.
In this embodiment, the authentication video and the authentication information are uplinked through the server device. After obtaining the authentication video and the authentication information, the server device may generate a data block for the authentication video and the authentication information, and add the data block into a block chain for authentication and evidence storage to obtain a corresponding authentication and evidence storage result (e.g., a hash value corresponding to the data block). Further, the server device may return the authentication result to the client device.
For example, a member node of the federation chain may first request to log in to a federation blockchain and obtain subsequent operation authorization; then according to the authentication information embedding method of the video digital watermark, acquiring an authentication video and embedded authentication information; then, the authentication video and the embedded authentication information are applied for registering a log-in chain through member nodes of the alliance chain; and then, returning an authentication and verification result according to the Hash value of the uplink new block.
In an example of integrating the video authentication information embedding and evidence storing process into the video creation production platform, firstly, a video creator applies for logging in the video creation production platform through a client (a video creation production platform client); then the video creator edits and creates the short video works by using the client; then the video creator initiates copyright protection on the created short video through the client, and simultaneously sends personal user information of the video creator and the created short video to the server; then the server receives the request, the user information and the short video of the client; then the server side generates authentication information based on the user information, and embeds the authentication information into the short video through the authentication information embedding method to generate an authentication video; then the server side registers the authentication video and the authentication information into a link through a alliance link by the block link-based copyright certificate storing method, and obtains an authentication certificate storing result; then the server side sends the authentication video embedded with the authentication information, the authentication information and the authentication and verification result to the client side; and then the video creator obtains the authentication video embedded with the authentication information, the authentication information and the authentication and verification result as the copyright protection result of the short video through the client.
Step S310: and returning the authentication and storage result to the client.
And returning the authentication and evidence storage result to the client, wherein the authentication and evidence storage result can be stored by the client and used in the subsequent video authentication.
The above process is exemplified below with video originality protection as an example scenario. It should be apparent to those skilled in the art that the video example is applicable to a variety of video types, short video, long short video, and shorter video material.
The process comprises the following steps:
step A: and receiving a copyright protection request sent by a user after completing video creation through a video creation production platform client.
In this example, a video creation production platform is provided for a user, i.e., a video creator, and the user can locally create a video through a client of the video creation production platform and request copyright protection for an original video created by the user through the video creation production platform.
When requesting copyright protection, the client of the video creation production platform may send a copyright protection request to the server of the video creation production platform, where the copyright protection request carries user information of a user and information of a video created by the user. After receiving the request, the video creation and production platform server performs copyright protection processing on the video based on the information therein, which is described in detail below.
And B: and performing digital watermarking processing based on the frequency domain on the video by taking the user information as authentication information to obtain the video embedded with the frequency domain digital watermark.
For example, a video creation and production platform performs frequency domain digital watermark embedding in a fixed partial region of each video frame image of the video. Specifically, a plurality of fixed regions may be selected from the video frame image for frequency domain digital watermark embedding, for example, the selected region is a square with a side length of N, and the positions of the selected region include an upper left corner, a lower left corner, an upper right corner, a lower right corner, and a middle of the image. Where N ═ sqrt (M) × w, M indicates the authentication information length such as 256, sqrt indicates square root formation, and w is the DCT window size, and is typically 2.
And C: and performing space domain digital watermarking processing based on a preset quantization threshold value on the video embedded with the frequency domain digital watermark to obtain an authentication video embedded with the space domain digital watermark.
For example, a quantization threshold K is set first, and for three channel values R, G, B of a pixel point in each video frame image of the video embedded with the frequency domain digital watermark, the quantization threshold K is used to quantize the three channel values to obtain the quantized channel values
B is B/k; then, on the basis of the quantized values r, g and b, embedding watermark data (authentication information) of one bit at the same time to obtain new values r ', g ' and b '; then, the inverse process of quantization is performed to obtain
Then, the corresponding pixel points in the video frame image are updated according to the pixel values R ', G ' and B '.
The effect of K is to set a range of allowable fluctuation of the pixel value, so as to allow recovery of the original watermark information under a larger variation of the pixel brightness, and K may be set to 3 alternatively.
Therefore, the method and the device realize the double hidden digital watermarking of the frequency domain and the space domain of the video, and obtain the authentication video.
Step D: and generating a data block according to the authentication video and the authentication information, adding the data block into a block chain to perform authentication and evidence storage, and obtaining an authentication and evidence storage result of the data block in the block chain as a copyright certificate of the video.
The regional chain is selected from a federation chain type, but is not limited thereto, and other types such as a public chain or a private chain type are also applicable to the solution of the embodiment of the present application.
For example, a member node of the federation chain may first request to log in to a federation blockchain and obtain subsequent operation authorization; then according to the authentication information embedding method of the video digital watermark, acquiring an authentication video and embedded authentication information; then, the authentication video and the embedded authentication information are applied for registering a log-in chain through member nodes of the alliance chain; and then returning an authentication and verification storage result according to the Hash value of the uplink new block, wherein the authentication and verification storage result is the copyright certificate of the video.
In addition, optionally, in the process of video creation by the user, the video material used by the user can also be authenticated to ensure the legality of the video material used by the user, so that the legality of the video created by the user can be ensured. For example, an authentication request for used video material sent by a user in the process of authoring the video may be received; obtaining video materials according to the authentication request, and extracting authentication information of the video materials; judging whether a copyright certificate corresponding to the video material exists in the block chain; and if so, acquiring the copyright certificate, and sending use indication information aiming at the video material to the user according to the comparison result of the copyright certificate and the extracted authentication information.
The use indication information may be prompt information to prompt a user whether the video material is legal or not, whether the video material can be used or not, and the like.
In this case, if the block chain does not have the copyright certificate corresponding to the video material, the corresponding prompt information, such as the prompt information that whether the video material is legal or not cannot be determined, can be sent to the user, and the user can decide whether to use the video material. If the block chain has the copyright certificate corresponding to the video material, comparing whether the copyright certificate is consistent with the extracted authentication information, if so, prompting the user that the video material is legal material protected by copyright, asking the user to apply for use according to a specified flow, and the like; and if the video materials are inconsistent, prompting the user that the video materials are illegal materials, prohibiting the user from using the video materials to create and the like. Of course, other forms of prompting information or usage indication information are equally applicable to the scheme in this example.
But not limited to the above examples, the solution of the embodiment of the present application may also be applied to other various scenarios, including but not limited to: video copyright storage and protection under a plurality of scenes such as teaching videos recorded for teachers in online education scenes, conference videos recorded for conferences in video conference scenes, video clips of various conference videos and the like.
For example, in an online education scenario, a request for copyright protection of a teaching video recorded for a teacher may be received; according to the request and preset authentication information (such as teacher user information or account information of a teaching platform), performing frequency domain-based digital watermarking on the teaching video to obtain the teaching video embedded with the frequency domain digital watermark; then, performing spatial domain digital watermarking processing based on a preset quantization threshold value on the teaching video embedded with the frequency domain digital watermark to obtain an authentication teaching video embedded with the spatial domain digital watermark; and generating a data block according to the authentication teaching video and the authentication information, adding the data block into a block chain to perform authentication and evidence storage, and obtaining an authentication and evidence storage result of the data block in the block chain as a copyright certificate of the teaching video.
For another example, in a video conference scenario, a copyright protection request for a recorded conference video may be received; according to the request and preset authentication information (such as user information of a conference host or account information of a conference platform and the like), performing frequency domain-based digital watermarking on the conference video to obtain the conference video embedded with the frequency domain digital watermarking; then, performing airspace digital watermark processing based on a preset quantization threshold value on the conference video embedded with the frequency domain digital watermark to obtain an authentication conference video embedded with the airspace digital watermark; and generating a data block according to the authentication conference video and the authentication information, adding the data block into a block chain to perform authentication and evidence storage, and obtaining an authentication and evidence storage result of the data block in the block chain as a copyright certificate of the conference video.
For another example, also in a video conference scenario, a copyright protection request for a recorded conference video may be received; acquiring a conference video and preset authentication information (such as user information of a conference host or account information of a conference platform) according to the request; analyzing a conference video to obtain a plurality of effective video segments (such as a video segment spoken by a host, a video segment spoken by an important participant, a plurality of video segments for a topic or theme, and the like) in the conference video; then, according to the obtained authentication information, performing digital watermarking processing based on the frequency domain on each conference video segment to obtain one or more conference video segments embedded with the frequency domain digital watermarking; then, carrying out space domain digital watermark processing based on a preset quantization threshold value on the conference video segment embedded with the frequency domain digital watermark to obtain one or more authentication conference video segments embedded with the space domain digital watermark; and generating a corresponding data block according to one or more authentication conference video clips and the authentication information (the corresponding data block can be generated for each authentication conference video clip and the authentication information respectively, or a data block can be generated by all the authentication conference video clips and the authentication information together), adding the data block into a block chain for authentication and evidence storage, and obtaining an authentication and evidence storage result of the data block in the block chain as a copyright certificate of the conference video clip.
According to the embodiment, the hidden digital watermark embedded in the video can be formed by watermarking twice for the original video works of the video creators, and then the video and the digital watermark are authenticated and stored by the block chain technology, so that whether the video is original or not can be effectively identified in the follow-up process. When the video is subjected to watermarking, the video is firstly subjected to frequency domain watermarking, so that the protection of a first-level hidden watermark can be realized, but in order to enable the video to have stronger attack resistance, a second-level spatial domain watermarking is added for the video on the basis of the frequency domain watermarking, and the spatial domain watermarking is performed on the basis of a quantization threshold value. Therefore, the video is stronger in attack resistance, and better in anti-interference performance on image change. In addition, on the basis of adding the digital watermark, the video and the digital watermark are added into the block chain, and due to the originality and the safety of data in the block chain, the generated authentication deposit certificate can effectively prove the identity of the video original author, provide a proof for the copyright protection of the video, and further guarantee the rights and interests of the original author. Therefore, through the scheme of the embodiment of the application, effective and active video work protection is achieved.
EXAMPLE III
Referring to fig. 4, a flowchart illustrating steps of a video data protection method according to a third embodiment of the present application is shown.
The video data protection method of this embodiment is explained from the viewpoint of video copyright identification, and includes the following steps:
step S402: a video authentication request is received.
For example, a video authentication request initiated by a client may be received. The client can send a video authentication request to the server through the video creation production platform so as to request the identification of whether a certain video or a certain video material is infringed.
The video authentication request carries information of a video to be authenticated.
Step S404: and obtaining the video to be authenticated according to the video authentication request, and extracting authentication information in the video to be authenticated.
For example, the video to be authenticated is obtained from the client according to the information of the video to be authenticated carried in the video authentication request, or the video to be authenticated is obtained according to the address indicated by the information of the video to be authenticated.
And after the video to be authenticated is obtained, extracting authentication information in the video. For example, extracting binary codes from each video frame image through the LSB-based spatial domain digital watermarking algorithm, and recovering authentication information of each video frame image through Reed-solomon codes error correction; then, extracting binary codes from each video frame image through the DCT-based frequency domain digital watermarking algorithm and recovering the authentication information of each video frame image through Reed-solomon codes error correction; then all the extracted authentication information is counted to obtain the authentication information with the most repeated occurrence times as the finally extracted authentication information.
The authentication information in the video to be authenticated can be generated by the method described in the first or second embodiment, and of course, schemes generated by other methods can also be applied to this embodiment. For example, the video to be authenticated may be a video subjected to only frequency domain digital watermarking, or a video subjected to only spatial domain digital watermarking, or the like.
Step S406: and acquiring an authentication deposit certificate corresponding to the video to be authenticated from the block chain, and determining an authentication result of the video to be authenticated according to the extracted authentication information and the authentication deposit certificate.
For example, if the authentication result represents that the authentication information is consistent with the authentication deposit certificate, determining that the video to be authenticated is not infringed; otherwise, a video infringement to be authenticated may be determined.
In one example, the functions of the present embodiment can be integrated into a video authoring production platform, and then: firstly, a user applies for logging in the short video creation production platform through a client; then the user uploads the suspected infringement short video to the server by using the client and initiates a short video authentication information extraction request; then the server receives the suspected infringement short video and extracts the authentication information by the authentication information extraction method of the video digital watermark; then the server side inquires the authentication and evidence storage result through the copyright service union link to obtain an inquiry result; then the server side sends the extracted authentication information and the alliance chain query result to the client side; and then the user obtains the extracted authentication information and the alliance chain query result through a client as a video authentication result of the short video.
In addition, in some scenarios, the video creator may also introduce some existing video material into its own video creation, and in such a case, the video creator needs to know whether the introduced video material may infringe. In this scenario, the video authentication request may be a request for requesting authentication of a video material for creating a video, and the video to be authenticated is a video corresponding to the video material; and in this case, if the authentication result indicates that the authentication information is inconsistent with the authentication deposit certificate, the client is indicated to prohibit the video creation by using the video material. Thus, the rights and interests of both the original video and the video creator are protected.
For example, a video creator applies for logging in a video creation production platform through a client; a video creator imports video materials through a client; the platform extracts authentication information of the video material; the platform checks whether the video material has authentication information and does not accord with the user information of the current video creator; if so, triggering an active copyright protection prompt, namely, reminding the video creator that the video material is unavailable due to copyright reasons by the client side, and forbidding the video creator to create and use the video material.
Through the embodiment, copyright detection and determination can be effectively carried out on suspected videos or video materials with use requirements, so that rights and interests of original videos and video creators are effectively protected.
