Abstract

The invention provides a video file full-link safe management and distribution method and system based on cloud technology. The distribution comprises the following steps: S1, encrypting a to-be-distributed video file to form a video content file, and generating an authorization file of the video content file corresponding to an authorization device; S2, hierarchically transmitting and pushing the video content file and the authorization file to a user side; S3, a user side play device decrypting the video content file and the authorization file, and playing the video content. Through the adoption of the method provided by the invention, the scenes of cloud-end encapsulation and encryption, hierarchic content transmission and pushing, content management of edge node, and final decryption and smooth playing of the play device are optimally designed, the existing prior art is well solved, the user watching experience under the multi-user concurrent play scene is maximally guaranteed.

Description

technical field [0001] The invention relates to the technical field of data security and transmission, in particular to a method and system for full-link security management and distribution of video files based on cloud technology. Background technique [0002] In recent years, with the rapid development of network technology and various industries, all kinds of information data are growing explosively. Users have more and more needs for various data, such as various audio and video files. How to securely manage and distribute these files has a great impact on copyright protection and user experience. Therefore, how to securely manage and distribute data is very important, especially for large data video files, whose copyright protection cannot be efficiently and widely distributed by streaming media or file segmentation. [0003] Large 4K video files and movie files with low compression ratio are very large files. Because of the huge files, long file transfer time, low en...
