Live broadcast stream media authentication method based on P2P network

Abstract

The present invention provides authentication method based on P2Pnetwork living broadcast stream medium, first step: user terminal examines live program information from indexes server, and sends playing certain program demand when process flow starts; second step: indexes server provides connection information of program source provider and information of playing program required digital certificate to user terminal; third step: customer terminal software checks whether or not local installs required digital certificate, if digital certificate has already be mounted, application can be applied at digital certificate server of program provider according to required digital certificate information; four step: program provider executes user authentication according to user demand, and distributes digital certificate to legality user, at the same time executes authentication and management to user; five step: after obtaining digital certificate, user registers in P2Pnetwork for transmitting of living broadcast stream medium, receiving stream medium data for executing decipher, decoding and playing.

Description

Technical field [0001] The invention relates to a method for realizing digital encryption of streaming media based on P2P network live broadcast and user authentication. technical background [0002] With the rapid development of Internet technology, the transmission of video and audio on the Internet has gradually become a trend. Online video live broadcast has adapted to this development and has received more and more attention from everyone. It is mainly used to realize the sharing and playback of network multimedia files by multiple users. [0003] P2P (Peer to Peer) means the peer-to-peer interconnection of network nodes. It should be said that, parallel to the current client / server master-slave interconnection model popular on the Internet, P2P realizes distributed resource utilization and sharing. Each node can perform peer-to-peer communication and can simultaneously receive, send, and receive information content. Store and integrate, and perform functions such as searchi...

AI Technical Summary

Problems solved by technology

[0008] This controllable P2P technical method has the following deficiencies: firstly, the restrictions on the P2P network and the control strategies imposed greatly reduce the degree of freedom of the P2P network. The high efficiency of the P2P network comes from a high degree of openness and free transmission, so this It will inevitably greatly reduce the efficiency of P2P network transmission, and the more controls and restrictions, the lower the efficiency

Users who break through the limit and some legitimate users can play. For users who crack the software and download while playing, malicious modification, recoding, conversion, and dissemination after downloading are unavoidable.

So for now, the protection of streaming media copyright has not been technically realized.
