Embodiment Construction
[0043] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
[0044] refer to figure 1 , shows a flow chart of the steps of a video processing method of the present invention, and the method may specifically include the following steps:
[0045] In step S101, the key frame in the original video is encrypted to obtain the first encrypted frame;
[0046] In a scenario, the client can obtain the original video from the server and play it. In order to improve the security of the original video, the server can encrypt the original video to obtain the encrypted video, and then send the encrypted video to the client, and the client can receive the encrypted video. The encrypted video sent by the server, and then decrypted to obtain the original video, and then the original video can be played.
[0047] In the above scenario, the original video is not expos...

The present invention provides a video processing method, device, electronic device and storage medium. Even if the criminals get the non-key frames in the original video, as long as the criminals have not cracked the key frames in the original video, it will be difficult for the criminals to restore the original video. Therefore, when encrypting the original video, the original video can be encrypted. Overall encryption, you can encrypt the key frames in the original video to obtain the first encrypted frame, and then obtain the encrypted video according to the non-key frames in the original video and the first encrypted frame. Since the key frames in the original video have been encrypted, therefore, It is difficult for criminals to restore the original video, which ensures the security of the original video. In addition, non-key frames in the original video may not be encrypted, thereby improving the encryption efficiency of the original video. Therefore, the present invention can reduce the time spent in the process of encrypting the original video under the premise of ensuring the security of the original video, thereby improving the encryption efficiency of the original video.
Description
technical field [0001] The present invention relates to the field of computer technology, and in particular, to a video processing method, device, electronic device and storage medium. Background technique [0002] At present, there are more and more videos on the network, and many users choose to watch network videos on the client. For example, the user can control the client to send a video acquisition request to the video server on the network, and then the video server will send the video to the video server according to the request. The client sends the video, and then the client can play the video for the user to watch. [0003] In order to improve the security of the video during transmission, the video server can encrypt the original video first, and then send the encrypted video to the client. In this way, what the client receives is the encrypted video, and then the encrypted video can be decrypted to obtain the original video, and then the original video can be p...
