Problems solved by technology

[0003] In order to improve the security of video content, the video is usually encrypted on the server side. The server decrypts the encrypted video and sends it to the client for playback, or downloads the encrypted video to the client and decrypts it to generate a temporary buffer video file for playback. However, there is a risk of copying the decrypted video when it is sent to the client or the temporary buffered video file generated by decryption, so the security is relatively low

Abstract

The embodiment of the present invention discloses a video playing method and device, wherein the video playing method includes: acquiring the video to be played, extracting the video data and video index of the video to be played, and performing the video data based on a preset strategy. Encrypt, and obtain the key generated during the encryption process, update the video index according to the key, obtain the updated video index, and send the encryption result and the updated video index to the terminal, so that the terminal can update the video index according to the encryption result and The post-video index plays the video to be played, so the security of the video content can be improved.

Description

Video playback method and device technical field [0001] The present invention relates to the field of computer technology, and in particular to a video playback method and device. Background technique [0002] With the development of Internet technology, more and more users can watch videos through various clients, or Download the video locally through the client. [0003] In order to improve the security of the video content, the video is usually encrypted on the server side, and the server will encrypt the video. The video is decrypted and sent to the client for playback, or the encrypted video is downloaded to the client for decryption and generation Temporarily buffer the video file for playback, however, the decrypted video is sent to the client or decrypted The resulting temporary buffered video files are at risk of being copied, so the security is relatively low. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a video playback me...
