  Video sharing sites like YouTube, Metacafe, Dailymotion, Vimeo, etc. provide
a platform for media content sharing among its users. Some of these videos are
copyright protected and restricted from being downloaded and saved. But users
can use various download managers or application programs to download and save
these videos. This affects the incoming traffic on these websites reducing
their hit rate and consequently reducing their revenue. Adobe Flash Player is
the most commonly used player for watching online videos. It uses RTMP (Real
Time Messaging Protocol) to stream audio, video and data over the Internet,
between a Flash Player and Adobe Flash Media Server.Here, we propose a plug-in
that enables the site owner control over downloading of videos from such
website. The plug-in will be installed at the client side with the consent of
the user. When the video is being played this plug-in will send unique keys to
the media server. The server will continue streaming the video after verifying
the keys. Download managers or application programs will not be able to
download the videos as they wont be able to create the unique keys that need to
be sent to the server.
