Problems solved by technology

However, in the existing video platform playback authentication mechanism, the entire video file playback string can be obtained by capturing packets by technical means, and then the video content on the video platform can be obtained by simulating the playback request, thereby stealing the copyright-protected video content
A large number of illegal hotlink requests increase platform bandwidth costs and server resources, causing serious economic losses

Embodiment Construction

[0036] Such as figure 1 As shown, the implementation steps of the method for preventing hotlink playback of network video-on-demand in this embodiment include:

[0037] 1) The client (such as a player or SDK, etc.) requests the playback backend to obtain fragment index files (such as m3u8, mpd, etc.);

[0038] 2) For each fragment in the fragment index file, the client dynamically specifies the encryption method according to the fragment file name filename of the fragment, and adopts the selected encryption according to the fragment file name filename and playback expiration time es of the fragment Encryption method generates the first authentication code token, and sends the segment file name filename of the segment, the first authentication code token, playback expiration time es and the encrypted version number version of the dynamically specified encryption method when requesting the segment. Through the above method, after the player or SDK obtains the m3u8 and mpd files...

Abstract

The invention discloses a method, a system and a medium for preventing link stealing playing in network video-on-demand. According to the method, a client side aims at each fragment in a fragment index file; dynamically specifies an encryption mode according to the fragment file name file name file of the fragment; according to the fragment file name file of the fragment, plays expiration time es,and encrypts the expiration time es in a selected encryption mode to generate a first authentication code token, and when the fragmentation is requested, the fragmentation file name file name, the first authentication code token, the playing expiration time es and the encryption version number version of the dynamic specified encryption mode of the fragmentation are sent. According to the invention, the difficulty of capturing the playing string of the technical packet is improved, the threshold of a stolen link technology is improved, the number of stolen link playing requests is reduced, the copyright of the content can be effectively protected from being damaged, and the bandwidth cost expenditure of a video platform and the resource consumption of a server can be reduced.

Description

technical field [0001] The invention relates to streaming media on-demand anti-hotlink technology, in particular to a method, system and medium for preventing hotlink playback of network video on-demand. Background technique [0002] At present, online video-on-demand urls (such as hls / dash) are generally encrypted in advance, adding encrypted fields in the play string, and then the server background or CDN authenticates the encrypted field of the play string to perform access authentication. However, in the existing video platform playback authentication mechanism, the entire video file playback string can be obtained by capturing packets by technical means, and then the video content on the video platform can be obtained by simulating the playback request, thereby stealing the copyright-protected video content. A large number of illegal hotlinking requests increased platform bandwidth costs and server resources, causing serious economic losses. Contents of the invention ...
