Abstract

The invention can be applied to the technical field of information security, and provides a web end video playing method and device, and the web end video playing method comprises the steps: generating a wasm file according to C language codes and a dependency library; slicing a to-be-played video to obtain a plurality of video clips; symmetrically encrypting respective video clips to obtain encrypted video clips and corresponding keys; and playing the to-be-played video at a web end according to the wasm file, the keys and the encrypted video clips. According to the web end video playing method and device provided by the invention, a private method is used for encryption, so that a user can be prevented from decrypting the played video file by himself / herself. In another aspect, the WebAssembly technology is utilized, so that the technical effect of efficiently decrypting the video can be achieved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a web-side video playback method and device. Background technique [0002] Due to the increase in production costs of existing film and television videos, membership or paid viewing modes are introduced. For example, some videos are private (such as members-only viewing videos), and video websites (such as Youku, bilibili, youtube, etc.) need to prevent videos from being Users download, disseminate, and leak privately. That is, users are allowed to watch videos but are not allowed to download and share videos. [0003] The existing technology generally adopts a public protocol based on HLS, and the server uses methods such as AES to encrypt the video, and sends the encryption key to the web, and the web browser uses the key to decrypt and play the video. The video resources downloaded by users are encrypted files and cannot be played directly. In the p...
