AI Technical Summary

Problems solved by technology

In addition, there is also a way to process video by adding a specific signature or randomly selecting data to calculate a check value, but this method also has problems such as easy forgery, transmission error codes and false positives.
It can be seen that the existing methods have difficulties in ensuring the anti-tampering of video CDN audio and video

Embodiment Construction

[0054] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0055] see figure 1 As shown, the embodiment of the present invention provides a video anti-tampering method based on index verification and real-time transcapsulation, comprising the following steps:

[0056] Obtain the original audio and video content, preprocess and generate indexes and ES fragments to be stored;

[0057] Store the index and the ES segment in the content library, and establish a mapping relationship between the index and the physical storage location of the ES segment; encrypt and store the index, and store the original text of the ES segment;

[0058] When the user requests audio and video services, the index is obtained according to the request, and the corresponding ES segment is pulled from the content library according to the index and the mapping relationship;

[0059] According to the index, the content of the pulle...

Abstract

The invention discloses an anti-tampering method and system for video based on index verification and real-time encapsulation, and relates to the field of CDN audio and video technology. The invention provides a verification word closely related to the content and concentrated information through the index, so as to ensure audio and video While tamper-proof, it reduces computing overhead and supports the transmission of audio and video content with a larger bit rate. Transform the filling and multiplexing package information of the index, change the original simple index into the basis for real-time conversion package, and change the storage content from the original file to independent pure audio and pure video, which is only verified in the final service, effectively avoiding It eliminates the risks of various tampering during transmission and storage, and realizes the anti-tampering capability of video CDN, which is not restricted by live broadcast and on-demand methods, nor by audio and video packaging formats.

Description

technical field [0001] The invention relates to the technical field of CDN audio and video, in particular to an anti-tampering method and system for video based on index verification and real-time transcapsulation. Background technique [0002] CDN (Content Delivery Network, content distribution network) is an intelligent virtual network built on the basis of the existing network, relying on edge servers deployed in various places, through the platform's load balancing, content distribution, scheduling and other functional modules, so that users can obtain Required content, reduce network congestion, improve user access response speed and hit rate. The key technology of CDN mainly includes content storage and distribution technology. Video CDN means that the content distributed and stored is audio and video. The storage of content in video CDN mostly adopts the method of segmented storage. Fragmentation and fragmentation rely on index (index) files to record key location i...
