Anti-hotlinking Technology For Mobile Streaming Media Service

With the video streaming service in the rapid development of mobile networks, building a anti-hotlinking mobile streaming media system has become the content providers and service providers face the important issues. Internet streaming media directly from the simple anti-hotlinking page address mode encryption is not feasible on mobile networks because of Internet streaming media system used IP addresses to identify users; Another mode effective anti-hotlinking with database, but It is too complexity to the mobile environment and mobile player used . Each mobile operators have built their own WAP gateway, the terminal through the WAP proxy to access the network, users will have the same IP address. The simple mobile phone operating system and the limited hardware processing power, thus requiring the verification process should be simple to the player.This paper analyzes the characteristics of mobile communication networks and terminals based on the detailed study of mobile streaming media transmission control protocol, and 3GPP mobile streaming media services in general were introduced at the same time architecture for mobile streaming media servers to do a thorough study. The paper also analyzes the mobile streaming media system structure, pointed out that the Anti-hotlinking module in the mobile streaming media system in place. Made by the user number and the server time, with the agreed parameters of MD5 of encryption, WAP server, streaming media server using a mobile phone passed to the cipher text, mobile streaming media servers cipher text contrast testing, building a set for mobile streaming media services Anti-hotlinking system.At the end we analysis and testing this Anti-hotlinking mobile streaming media system. Experimental results show that this anti-hotlinking mobile streaming media system to properly validate user requests through legal and effective rejection of illegal request, to prevent the use of outdated links, can be applied to mobile environment and a variety of mobile streaming media player.
