All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first", "second", "third", "fourth", and the like in the description and the claims of the present invention are used for distinguishing different objects, and are not used for describing a specific order. The terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the existing scheme for copyright maintenance, an operator contacts an administrator of a third-party live broadcast platform, and the administrator of the third-party live broadcast platform seals off an account number of an unauthorized user on the platform. It is obvious that this takes a long communication time to complete. Based on this, the embodiment of the invention discloses a method, a device, electronic equipment and a storage medium for protecting the copyright of digital works based on a playing platform, wherein whether the corresponding platform has the playing authority is determined by detecting the digital watermark information of the digital works, and when the corresponding platform has no playing authority, a copyright profit distribution strategy is sent to the platform to improve the enthusiasm of platform managers for copyright verification protection, so that the protection of the digital works produced by copyright parties is enhanced. Through the scheme, even if the works are copied or downloaded, effective monitoring can be carried out, and then piracy attack and copyright protection can be achieved. And corresponding protection marks are arranged in the digital watermark information, so that the protection of a copyright side on the copyright is greatly improved.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for protecting digital works based on a playing platform according to an embodiment of the present invention. The method is suitable for intelligent equipment such as mobile phones and tablet computers with processing functions and computing equipment such as computers and servers, and even can be used as an image acquisition device with processing functions, for example, processing devices with image processing functions such as a single chip microcomputer, an FPGA and an ARM are integrated in the image acquisition device, and images acquired by the image acquisition device are processed to calculate the water level height. As shown in fig. 1, the method for protecting digital works based on a playing platform includes the following steps:
s101: the method comprises the steps of obtaining playing platform information and content information of a digital work to be played, wherein the content information comprises work information and digital watermark information.
In this step, the information of the playing platform needs to be acquired first, and the playing platform acquires the information of itself as a subsequent permission verification basis. Since not all the playback platforms have playback rights corresponding to the movie copyright, it is necessary to acquire corresponding playback platform information to determine whether it has the corresponding rights. Similarly, when a corresponding user wants to watch the movie of 'capture of the crown' on the playing platform, the corresponding playing component can be clicked to play the movie, and at this time, corresponding work information, namely specific movie playing page content, needs to be acquired, and corresponding digital watermark information needs to be acquired, so that whether the corresponding user has corresponding copyright rights is determined through the digital watermark information. Or when the user uses the corresponding player to play the downloaded movie, the corresponding work content and the corresponding digital watermark information are obtained; when the movie is released, watermark information must be embedded in advance as an identifier, so that even if a subsequent user has corresponding authority to download the movie and sends the movie to a user without the authority to watch, the user without the authority cannot open the corresponding work due to the existence of the digital watermark information. The digital watermark information includes corresponding copyright identification information that is used to determine copyright ownership.
More preferably, before the obtaining the content information of the digital work to be played and the information of the user, the method further includes:
the digital watermark information is encrypted and randomly embedded into a data frame of a preset time period of corresponding work information to obtain a digital work to be played, the work information comprises video information or audio information or image information, and the digital watermark information is invisible digital watermark information.
For example, a digital watermark may be embedded in the video between the 2 nd minute and the 5 th minute, which facilitates subsequent watermark detection and extraction. When preparing to distribute corresponding movie works, the relevant content embedded for the watermark information needs to be embedded with corresponding identification content. The specific digital watermark is that after the pixel information is extracted, the corresponding authentication information is filled in the corresponding pixel, and when the digital watermark is detected, the corresponding original image can be recovered from the watermark image, and the image is filled. After digital watermark filling, a corresponding multi-level copyright structure can be obtained, wherein the multi-level copyright structure comprises copyright information, storage information, transaction information, use authority and the like; the spread range of the works and the copyright owner are limited by the content.
When the digital watermark information is set, the digital watermark information is set as invisible watermark information, so that the watching effect is not influenced in the whole movie watching process, and the noninductive playing content is realized; when watermark information is embedded, the corresponding data frame can be directly extracted and watermarked, then the watermarked data frame is restored to the original position, and information can be embedded by adding a digital watermark frame. Both of the above two ways can be implemented.
Specifically, fig. 2 is a schematic flowchart of a watermark information embedding process disclosed in the embodiment of the present invention, and as shown in fig. 2, the encrypting and randomly embedding the digital watermark information into a data frame of a preset time period of corresponding work information to obtain a digital work to be played includes:
s100 a: scrambling and converting the digital watermark information by adopting a scrambling and converting formula to obtain scrambled watermark information, and recording the scrambling times; the scrambling transformation formula comprises:
s100 b: randomly acquiring a corresponding data frame in corresponding work information;
s100 c: performing block histogram adjustment on the data frame by adopting a histogram adjustment formula to obtain an adjusted data frame, and recording a histogram adjustment record;
s100 d: performing integer wavelet forward transformation on the adjusting data frame, and embedding the transformed adjusting data frame into work information to obtain a corresponding digital work;
s100 e: and embedding the scrambled watermark information and the histogram adjustment record into the digital work to generate the digital work to be played.
More specifically, the operation of the block histogram and the acquisition of the adjustment record are realized by the following steps: the image is scanned in an inverted S-shaped sequence and is unfolded into a one-dimensional sequence, so that the pixel overflow can not occur in the translation operation of the carrier, and the following contents are obtained after the translation of the m-layer histogram:
in the pixel adjustment process, recording the maximum value of increase and decrease, and the right shift and the left shift of the mark point are different under different conditions, and the pixel position is contracted by using the adjustment recording mark with the same size as the carrier image, and the generated image is subjected to lossless compression by adopting run-length coding.
By the method, one image is scrambled in two directions at the same time, for a digital image, a certain pixel point in an acquired data frame can be mapped to a new pixel point, the original image becomes different by continuously repeating the process, namely, the image scrambling is realized.
In the embodiment of the application, because the watermark information is invisible, the difference after embedding is difficult to be respectively found from the visual angle, so that when the watermark is embedded, the peak signal-to-noise ratio is adopted to measure the watermark embedding capacity, and when the peak signal-to-noise ratio reaches a certain value, the requirement is met. The above mentioned data scrambling is a first-level data encryption, and more preferably, the random embedding of the digital watermark information into the preset time interval of the corresponding work information to obtain the digital work to be played includes:
and encrypting the plurality of digital watermark information and randomly embedding the plurality of digital watermark information into the data frames of the plurality of preset time periods of the corresponding work information to obtain the digital work to be played, wherein the plurality of digital watermark information jointly form secondary encryption information.
For a number of preset time periods, it may be inserted for 2 nd to 3 rd minutes, for 10 th to 11 th minutes, for 30 th to 31 th minutes, etc.; by the method, the position of the watermark can be more quickly positioned when a user detects the watermark, and the watermark detection efficiency is improved. The multi-frame watermark is embedded mainly for realizing secondary encryption, for example, the number of the inserted watermark data frames is 5, each frame is matched with a number, then a group of passwords is formed by a plurality of groups of data frames together, and the effective content is confirmed only if all data are matched. Besides the mode of digital matching, the method can also adopt the forms of characters or symbols and the like, and the security of data transmission detection is greatly improved through the mode.
S102: and calling a watermark identification algorithm of the playing platform to extract the digital watermark information so as to obtain corresponding copyright information.
In the embodiment of the application, the playing end can be a player or a playing component in a playing platform; a watermark recognition algorithm is built in each playing end to recognize the digital watermark; after extracting the corresponding digital watermark information, further identifying the digital watermark information to determine the corresponding copyright information; and determining whether the corresponding playing platform and the corresponding playing user have the right to play the works or not through the copyright information.
Further, fig. 3 is a schematic diagram of a flow of extracting watermark information disclosed in the embodiment of the present invention, and as shown in fig. 3, the invoking of the watermark identification algorithm at the playing end to extract the digital watermark information to obtain corresponding copyright information includes:
s102 a: calling a watermark recognition algorithm of a playing end to extract scrambled watermark information and a histogram adjustment record from a digital work to be played;
s102 b: carrying out reverse scrambling transformation on the scrambled watermark information to obtain original watermark information;
s102 c: and obtaining corresponding copyright information according to the original watermark information, wherein the copyright information comprises a copyright author, an open authority user, a copyright beneficiary and a copyright beneficiary mailbox.
The inverse scrambling transform is a periodic transform, and when the number of iterations reaches a certain step, the original image, i.e. the recovery watermark, will be obtained. Invisible watermarks are embedded into the original digital carrier, digital information changes, and the distortion degree is lower than a visual or auditory perception threshold; if people can not feel the visual change of the embedded watermark in the image, the value of the carrier can be embodied.
The above steps are watermark reduction steps, that is, corresponding scrambling information is extracted from the digital work to be played to reduce watermark information; besides the restoration of the watermark information, the original data frame can be restored. Because the histogram embedding mechanism is adopted and the adjustment record is recorded at the same time when the data is embedded, the data can be restored by adjusting the record. Histogram parallel reversible watermarking algorithm: a multi-layer watermark embedding mechanism is adopted, so that better image visual quality is obtained, higher embedding capacity is obtained, more various data can be embedded to ensure the integrity of copyright information, and an image synchronization algorithm with image characteristic points as a table is introduced into a reversible watermark algorithm, so that the robustness is improved.
Specifically, in the embodiment of the present application, an integer wavelet transform technology is used to implement reversible watermarking, and in order to solve the problem, a block histogram is used to perform adjustment when data overflow occurs in the process of performing wavelet transform. Inhibiting data overflow by using a block histogram, and improving algorithm robustness by scrambling watermarks by using bidirectional Arnold transformation; the watermark extraction and recovery process can be carried out according to the inverse process of the embedding process, and the operation is simple. And extracting the pre-watermark from the watermark image and recovering the carrier image by adjusting the marks in the recording and embedding processes through the histogram.
S103: and determining protection identification information according to the copyright information and the playing platform information, if the protection identification information is allowed to be issued, determining whether a corresponding playing platform has a playing authority, if not, extracting a copyright profit allocation strategy in the copyright information, and displaying the copyright profit allocation strategy.
After determining the protection identification information according to the copyright information and the playing platform information, the method further comprises:
and if the protection identification information is not allowed to be issued, executing digital work deletion operation to delete the digital work to be played.
The protection identification information in this embodiment mainly includes identification information in two aspects, one is that playback is not allowed, which is mainly to prevent piracy, when the protection identification built in the corresponding work information is that only a specific preset platform is allowed to play, at this time, if the detected playback platform information is not a preset platform, playback is not allowed; and simultaneously, executing a deleting operation to delete the corresponding work information. This can greatly reduce the instances of piracy, since the corresponding identification information may not be allowed to be played as long as it is detected.
In the embodiment of the application, the digital watermark work is the information of the visible digital watermark work, namely the digital watermark work can be detected by naked eyes; at this time, the digital watermark can be detected by setting an image recognition algorithm, so that even after the image is recorded by other users with the camera device, the recorded image can display the corresponding identifier due to the existence of the digital watermark, and the corresponding platform cannot play the image. When the digital watermark information is invisible digital watermark information, the invisible digital watermark information can be detected through a watermark detection algorithm built in the playing platform, and the detection effect of the method of detecting the corresponding invisible digital watermark information through the watermark detection algorithm is very good for the downloaded film. In specific implementation, a developer can set the algorithm according to actual conditions.
For a very popular movie work, the copyright may be bought by a certain platform or platforms; at this time, the platform does not want the movie to be widely spread, because more users will not log in the corresponding platform to watch the movie, the activity of the video platform is reduced, and no good benefit can be brought to the platform, therefore, for the above situation, the protection identifier may be relatively strictly required, and when it is detected that the protection identifier is set to disallow playing, the video information is directly deleted; and record the corresponding user information, facilitate the copyright side to pursue the liability.
However, most video and audio authors would prefer to be able to spread widely and to generate corresponding benefits through such wide spread. At this time, if the protection level set by the protection identifier is too high, the transmission is not facilitated, and the video is more facilitated to be transmitted by setting another mode in the application. When a pirate user records or downloads and broadcasts a corresponding video, it indicates that the pirate user has a higher broadcast degree, at this time, the protection identifier may be set to allow distribution, and a preset copyright revenue distribution policy is sent, for example, "when the user purchases a video viewing right on the platform, revenue sharing is performed according to 5/5. And the 'OR' pays 10 ten thousand, and the subsequent benefits of the film and television copyright are all owned by the platform. "besides the fixed revenue distribution mode can be directly built in, revenue distribution setting can be carried out according to the relevant information of the playing platform; for example, information such as daily activity amount of a playing platform or single-day video click amount can be obtained to match different profit sharing ratios, for a playing platform with large daily activity amount, for example, the playing platform can be divided according to 5:5 when the playing platform reaches a first preset threshold, the playing platform can be divided according to 4:6 when the playing platform reaches a second preset threshold, and for the playing platform reaches a third preset threshold, the playing platform can be divided according to 3:7 when the playing platform reaches the third preset threshold; the transaction rate is improved through different grading settings, and further the video transmission degree and the profit achievement of a copyright side are improved. The copyright side can dynamically adjust the income scheme according to the actual situation through the set dynamic income scheme, and the copyright trading efficiency is improved.
Further, after the displaying the copyright revenue allocation policy, the method further includes:
and receiving unlocking information sent by the copyright side of the content information, and unlocking the playing permission of the corresponding work information on the playing platform according to the unlocking information. That is, after the communication between the playing platform and the copyright party is completed and payment is completed, the playing platform can receive unlocking information sent by the copyright party to unlock the corresponding playing permission; therefore, the platform can play corresponding video on the platform according to the corresponding playing authority.
More preferably, after determining whether the corresponding playing platform has the playing right, the method further includes:
if the playing platform has the playing authority of the work information, obtaining the use user information and the preset user identification at the playing platform;
and if the use user information is consistent with the preset user identification, playing corresponding work information.
That is, besides information supervision on the platform, specific users can also be supervised, because if only information supervision is performed on the platform, and users are not limited, there is a vulnerability that after a member user downloads a corresponding movie, other users can directly play the movie on the playing platform without further copyright charge, which is very disadvantageous for copyright parties. Therefore, further, the user information includes a mac address, geographic location information and user identity information; the preset user identification comprises copyright registration information and copyright party communication information;
after the preset user identifier is extracted according to the copyright information, the method further comprises the following steps: and if the user identity information is inconsistent with the copyright registration information, sending a payment purchase page to a user side or sending corresponding mac address and geographic position information to a copyright party according to the copyright party communication information to perform message reminding.
The method includes that corresponding user information logged in at a playing platform is obtained, two conditions exist when the user information is obtained, one is a platform login user, the other is a tourist, namely the user without the login platform, and for the tourist, the charging copyright is generally not opened, so that the film source is not played directly or the login of the film source is reminded. And for the platform login user, judging whether the platform login user has the right to watch the corresponding movie, namely judging whether the platform login user is consistent with copyright login information, if so, directly playing the movie, and if not, sending a payment purchase page to the corresponding user side to remind the user of purchasing and playing, or sending the corresponding user information to a copyright party to carry out message reminding. Because the specific mac address and the geographic position information can be acquired during information acquisition, more accurate information can be provided for a copyright side during message reminding. In the embodiment of the application, the time of the earliest frame of video containing the digital watermark can be identified, the video before the time point of the frame is played, and when the frame is played, the playing is not allowed, and the purchase layout is popped up.
Further, before the sending the pay-per-purchase page, the method further includes:
and playing the work information of preset time, wherein the preset time comprises time information corresponding to continuous data frames or time information corresponding to a plurality of discrete data frames.
In order to bring better playing experience to users and better publicity to movies, in the embodiment of the application, even if the users do not have the right to play the movies, the users can be provided with free minutes to watch the movies, and the users can be attracted by the movies to generate purchasing behavior through the free minutes, so that the copyright revenue is improved. Specifically, 5 minutes may be set as a time that the non-member user can play.
Specifically, the first five minutes of the movie can be set as playing content, and the open five minutes can also be set for the user to select. Selecting five minutes open may enable the user to make a better selection. Specifically, the user can drag the playing component to the 5 th minute, and when the playing component is released, a movie can be played and the recording of time is started; when the time is 2 minutes, the user wants to watch the content corresponding to other time, the user can drag the playing component to a corresponding time period, the timing is stopped in the dragging process of the playing component, and the timing is started when the playing component is released. The mode can enable the user to play at any point on the time axis, and the playing is not limited; the change of the mode greatly improves the enthusiasm of users for watching the films and improves the purchasing behavior of the users from a certain level. The existing scheme can only set fixed time for showing the film, such as 2 minutes before the film, but the flexibility of film copyright authentication is improved due to the adoption of a digital watermark nesting mode, so that the watching selection of the film is more diversified. Besides the specific time period, the time may be set according to a proportion, for example, 2% of the time length of a video may be set, which can cover a wider range of video contents, because there are some short videos, which are only 8 minutes, and if 5 minutes can be played, all contents can be played basically, so in the embodiment of the present application, the time may be set according to a percentage of the time length.
In the embodiment of the present application, the reason why the corresponding video is allowed to be downloaded is to improve the spreading degree of the movie, and if the movie is directly limited to be incapable of being downloaded, the spreading degree of the movie is greatly reduced, which is not beneficial to spreading of related movies, and is also not beneficial to charging the copyright by the copyright issuer. Due to the adoption of the authentication mode of the digital watermark in the embodiment of the application, even if the user can download the video, namely the user can spread the corresponding video, the user needs to pay further to watch the specific content in the video. According to the scheme of the embodiment of the application, on one hand, the spread range of the film is greatly expanded, on the other hand, the benefits of copyright parties can be effectively maintained, and powerful technical support and support are provided for copyright protection of digital works.
In addition to copyright restrictions on video, copyright restrictions on audio may also be applied, with the particular principles being similar to the manner in which video is described above. For digital artwork, it is a little different, because the digital artwork is static, the content of a single frame can be set to 5 seconds as the time that the user can watch after the digital artwork is digitized, and after more than 5 seconds, the digital artwork is subjected to mosaic processing or locking processing.
In the embodiment of the invention, the digital work copyright protection method based on the playing platform determines whether the corresponding platform has the playing authority or not by detecting the digital watermark information of the digital work, and sends the copyright profit distribution strategy to the platform to improve the enthusiasm of platform managers for copyright verification protection when the corresponding platform has no playing authority, thereby enhancing the protection of the digital work produced by copyright parties. Through the scheme, even if the works are copied or downloaded, effective monitoring can be carried out, and then piracy attack and copyright protection can be achieved.
