Audio and video encryption protection on-demand method and device and electronic equipment

Abstract

The invention discloses an audio and video encryption protection on-demand method, an audio and video encryption protection on-demand device and electronic equipment, and aims to solve the problems that in the prior art, the content of a playing end is easy to leak, the volume of an encrypted file is increased, and audio and video files need to be re-coded and re-decoded in encryption and decryption operation, so that the operation is time-consuming and labor-consuming. And the requirement on hardware is high. The video-on-demand method comprises the following steps: S1, encrypting and decrypting audio and video contents; s2, authorization of the cloud authorization center; and S3, client-side video-on-demand. According to the on-demand method and device and the electronic equipment, cache files are not generated in the on-demand process, file reading and writing time is shortened through file copying, destructive processing is carried out on each frame so that it can be guaranteed that audio and video file content is not read normally, the problem of content leakage of a playing end is prevented, the file transmission bandwidth requirement is low, and the file transmission efficiency is high. Time consumed for playing audio and video files to a player is short, playing and storage are both under authorization protection, content leakage is prevented, and the rerecording scene and time are further traced through rerecording watermarks.

Description

technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to an audio and video encryption protection on-demand method, device and electronic equipment. Background technique [0002] The audio and video on-demand service provides users with on-demand services such as audio and video through the player. The audio and video data on the server side is downloaded to the client through the streaming media protocol. The data is sent to the graphics card and sound card for playback. [0003] The existing common audio and video encryption protection technology is DRM (Digital Rights Management) technology. The working principle of DRM technology is to first establish a digital program authorization center, encode and compress the digital program content, and use a key (Key) for encryption protection. (lock), the encrypted digital program header stores the KeyID and the URL of the program authorization center. When the user o...
