A proxy-based system for fingerprinting of streaming MPEG video

Watermarking has been widely used to protect the ownership of the offline video. Real-time watermarking is the process of embedding watermark information into the host data in real-time. In this paper, we introduce a system for real-time watermarking of streaming videos. The proposed system is capable of watermarking MPEG streaming videos using standard video streaming protocols such as RTSP/RTCP/RTP. The proposed system eliminates the problem of storage requirement of the offline system. To make the watermark process fast enough, we embed the watermark bits in compressed domain while the video bits are streamed to the client.
