Anti-leech method and system, CDN server and client

Abstract

The invention discloses a hotlink protecting method and system, a CDN server and a client side and relates to the field of three-network integration. According to the hotlink protecting method and system the CDN server and the client side, a redirection mode is used, a transcoded IP of the client side serves as hotlink protecting information to be stored in a redirection URL, so that the hotlink protecting information is carried when the client side requests fragmentation files later, a server side identifies the legality of a user by detecting whether the connection IP of the requesting client side is identical with the IP carried in the hotlink protecting information in the URL or not, it is ensured that all the requested content and the user are bonded together through the transcoding mode of combining a redirection path and an IP address, and hotlink protecting can be effectively achieved; the content of an original index file is not modified at all, the load of the server is reduced, and the transmission efficiency is improved.

Description

Technical field [0001] The invention relates to the field of triple play, in particular to an anti-leech chain method and system, and a CDN server and client. Background technique [0002] HTTP Live Streaming (HLS for short, Hypertext Transfer Protocol real-time streaming) is an HTTP-based streaming media network transmission protocol proposed by Apple. The main difference between HLS and traditional streaming media technology is that HLS cuts a program into equal-length fragments (or fragments) according to the length of time (such as 10 seconds), and files in the same time period are also transcoded to generate files with multiple bit rates. , And indexed by the main and sub M3U8 files, the player assembles and plays streaming media according to the M3U8 index files. [0003] At present, the mainstream anti-leech technology for HLS is to add anti-leech to each sub-file in the M3U8 file. Such as figure 1 As shown, the basic processing flow of the program is as follows: [0004] S...

AI Technical Summary

Problems solved by technology

[0012] The technical problems to be solved by the embodiments of the present invention are: adding anti-hotlinking information to all fragmented files and decrypting the problem that the server has a heavy burden, and adding anti-hotlinking information to all fragmented files makes the data volume of the index file larger. problem with download speed
