Secure Compressed Domain Watermarking for H.264 Video

Exponential growth of the internet provided new ways of propagating and sharing digital video data. Thus ownership protection of the video data is critical and important in this era. Though there are many standards and technologies available to efficiently share the digital video, almost all of them lack ownership protection mechanism. This paper proposes new compressed domain secure digital watermarking algorithm for H.264 video. Our algorithm selects the macroblocks in a pseudo random sequence based on a secret key and based on the content of the macro-block. The proposed algorithm is of low complexity and suitable to embed watermark in real time along with H.264 video encoding.
