A Secured Adaptive HTTP-Based Video Streaming System Using AES Algorithm

Abstract

Streaming video is a process of transferring moving images or video over the internet in a compressed form to viewers so that it can be viewed in real time. Streaming video technology is becoming more powerful all the time and appreciable works have been done in this area. However, security and adaptation of video are still problems to be tackled in the area of video streaming. In this paper, a secured and adaptive HTTP video streaming system (SAHVISS) was designed. The system was implemented using PHP, HTML5, Angular JS, Java Script and SQL Server database. It was tested on different computers and mobile devices using various web browsers. SAHVISS consist of four components namely Video Source, Streaming Server, Distribution Server and Client. The Streaming Server is made up of two sub-components namely the media encoder and the streamer. The server requires a media encoder to converts raw (uncompressed) digital video to a compressed format while the streamer breaks the encoded media into segments and save them as file. The distribution server comprises of Content Delivery Network and the Web server which delivers media file and the index files to the client over Hyper Text Transfer Protocol (HTTP).  The performance of SAHVISS shows that it provides an efficient technique for solving the issues of adaptation and privacy/security of streaming video content. It is a robust, secured and an adaptive http video streaming system.
