Video anti-stealing-link method based on OTT service

Abstract

The invention provides a video anti-stealing-link method based on OTT service. The video anti-stealing-link method includes the steps that the access request of a client for service request address AU is received, and a user characteristic string US is generated; a video index file link IL is generated according to the user characteristic string US; a video index file link access request of the client is received, whether the user characteristic information in the video index file link access request is matched with the user characteristic string US included in the video index file line IL is judged, and if yes, access entrances of all video clips are generated according to the original access entrance of all the video clips included in the video index file and the user characteristic string US, and a video index file content IC is generated to be returned to the client; the video clip access request of the client is received, whether the user characteristic information in the video clip access request is matched with the user characteristic string US included in the access entrances of all the video clip files is judged, and if yes, the video clips are returned to the client.

Description

technical field [0001] The invention relates to the technical field of Internet video information, in particular to an OTT service-based video anti-leeching method. Background technique [0002] In recent years, the OTT business has been in a period of vigorous development both at home and abroad. The main video and audio transmission protocols in the OTT business include: HTTP Live Streaming (HLS), HTTP Dynamic Streaming (HDS) and other video transmission protocols, and may be used as The next generation of international standard Dynamic Adaptive Streaming over HTTP (DASH) protocol. [0003] HLS is a streaming media network transmission protocol proposed by Apple. Its working principle is to divide the entire stream into small HTTP-based files for download, and only download some each time. While a media stream is playing, the client can choose to download the same resource at different rates from many different alternate sources, allowing the streaming session to accommod...

Problems solved by technology

[0009] Using anti-leech methods such as session, cookie, and reference-url usually only protects direct video links in web pages; however, HLS, HDS, and DASH in OTT services all adopt a secondary structure, and information such as session, cookie, and ref-url The first-level index file cannot be passed to the access request for the second-level video slice file, and the content of the second-level video slice cannot be effectively protected. Therefore, it is impossible to prevent hotlinking parties from slicing the second-level video by simulating the generation of the first-level index file. content hotlinking

[0010] The traditional anti-leeching method of carrying an authentication string in the link usually relies on a unified user authentication center to authenticate the link, which requires the user to perform login authentication in actual use, resulting in cumbersome operations and poor user experience

[0011] At the same time, a large amount of video content on the OTT page is distributed through a commercial CDN. A large number of video slice index files and actual slice files are distributed and cached in multiple cache servers of the CDN. A unified user authentication center is used to access all these slices. Requesting certification, on the one hand, has high requirements on the processing performance of the certification center, which increases the construction cost of the OTT operator; on the other hand, it requires a certain authentication interface connection between the commercial CDN and the OTT operator, which greatly increases The development cost of both parties is increased, and the universality of promotion is not good
