Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
As shown in fig. 1, which is a flowchart of embodiment 1 of a method for managing copyright of video disclosed in the present application, the method may include the following steps:
s101, when an original video needs to be played, judging whether the player belongs to a legal player, if so,:
when a user needs to play an original video, an authorization service is executed first, and whether a player used for playing the original video belongs to a legal player is judged, that is, whether the player is authorized is judged.
S102, acquiring an original video;
and when the player is judged to belong to a legal player, namely the player has the authority to play the original video, further acquiring the original video.
And S103, playing the acquired original video through a player.
And finally, playing the obtained original video through a player.
In summary, in the above embodiments, when the original video needs to be played, it is first determined whether the player belongs to a legal player, and when the player belongs to a legal player, the original video is acquired, and then the acquired original video is played by the player. The legality of the player can be judged firstly when the video is played, and compared with the prior art, the copyright of the video can be managed more effectively to prevent the video from being stolen.
As shown in fig. 2, which is a flowchart of embodiment 2 of a method for managing copyright of video disclosed in the present application, the method may include the following steps:
s201, when an original video needs to be played, establishing transmission control protocol long connection between a player and an authorization server;
when the original video needs to be played, the validity of the player needs to be verified, and when the validity of the player is verified, the player and an authorization server establish transmission control protocol long connection.
S202, the player and the authorization server exchange asymmetric public keys mutually;
then both parties exchange asymmetric public keys
S203, the player and the authorization server respectively verify whether the signature of the other party is legal, if so, the player belongs to a legal player;
and the two parties verify whether the signatures of the two parties are legal or not, and when the signatures of the two parties are both legal, the player is indicated to belong to a legal player.
S204, the authorization server obtains a play key and a play control script;
and when the player belongs to a legal player, requesting an authorization server to acquire a play key and a play control script. When the authorization service is idle, the asymmetric keys are generated in batch and then stored in a file, the authorization server establishes a key pool, when a play request is made, a key is taken out from the key pool for use, and if the number of keys in the key pool is small, the key generated in advance is read into the key pool, so that the service performance is improved.
S205, requesting a hotspot service to acquire a scheduling address and related information of an original video;
the hotspot service is then requested to obtain the scheduling address and other relevant information of the original video, such as the movie title, indirection, etc.
S206, requesting a scheduling service to match a content distribution network download address to the player;
then, a scheduling service is requested, and the scheduling service can match an optimal content distribution network download address for the user according to the whole bandwidth use condition of the current content distribution network and the region condition of the user.
S207, downloading the original video based on the content distribution network downloading address;
and downloading the original video through the matched content distribution network downloading address to obtain the original video.
S208, playing the obtained original video through a player;
s209, when the original video is played, the edge node of the content distribution network encrypts the original video in real time;
the method further adopts a video real-time encryption technology, when the user plays the original video, the content distribution network edge node encrypts the original video being played in real time, so that different encryption algorithms and keys are used for watching each time, and the cracking difficulty of the video is increased.
S210, when the original video is downloaded, the content distribution network edge node encrypts the original video in real time.
In addition, when the user downloads the original video, the original video is encrypted on the edge node of the content distribution network in real time, so that the advantages that even if the same user watches the same video, the encryption algorithm and the key are different when watching each time, and the cracking difficulty is increased. In addition, because the encryption is carried out in real time, the non-encrypted original file is stored in the content distribution network, when the non-encrypted video needs to be played, two documents are not stored, and the storage space of the content distribution network is saved.
It should be noted that, in the present application, an SDK (Software Development Kit) is designed as a universal framework, and the framework can load different broadcast control scripts, and implement different service logics without recompiling, that is, loading DRM (Digital Rights Management) scripts, so as to play DRM videos, and loading live broadcast scripts, so as to play live broadcast streams.
The SDK is divided into several layers, the first layer is a player and is a caller, the second layer is an interface layer of the SDK, the third layer is a service analysis layer and is used for processing specific services, and the fourth layer is a scheduling module and is used for scheduling and processing service requests.
The broadcast control script supports hot updating, and the specific broadcast service is realized by the script, so that the broadcast control SDK is as simple as a web program when being updated, and is convenient to update at any time and any place. The method has the advantages that the positioning problem is simple, sometimes some users can not tell to watch a certain video, and a broadcasting script is customized for the users, so that the positioning problem can be solved quickly.
In addition, the scheduling module is realized by using coroutines, the use mode of the coroutines is similar to that of the threads, but the coroutines are not threads, any multiple coroutines can exist in one thread, only one coroutine can be in the thread running at the same time, and in other words, the asynchronous effect is realized in a synchronous mode. The scheduling module is a core part of the broadcast control SDK, schedules and processes a logic request generated by the broadcast control script, and provides a set of perfect Application Programming Interface (API) for the broadcast control script to use.
As shown in fig. 3, which is a schematic structural diagram of an embodiment 1 of a video copyright management system disclosed in this application, the system may include:
the judging module 301 is configured to judge whether the player belongs to a legal player when the original video needs to be played;
