ENHANCED WAVELET PACKET BASED UN COMPRESSED VIDEO WATERMARKING ALGORITHM WITH FRAME SELECTION AND HVS CRITERIA

Digital video is a group of moving visual images, text and sounds. The popularity of using digital video in Internet leads to illicit copying and dispersal of content. In order to avoid this, video watermarking technique are used as a preventive measure for illegal copying of copyrighted material. In this paper, watermarking algorithm for identification of optimal frames and embedding of nested watermark using static block selection is proposed. The nested watermark is embedded in the uncompressed video data and is extracted without the use of original video sequences. These algorithms preserve the video quality and provide more security. The performance of the algorithm is analyzed using Peak Signal to Noise Ratio, Normalized Correlation and Mean structure similarity index with respect to various attacks. Experimental evaluation demonstrate that the proposed algorithm perform satisfactorily compared to traditional algorithms in terms of payload, transparency and it is also robust against various attacks.
