Objective: This paper proposes a new integrated system based on a video watermarking algorithm with high imperceptibility, improved security, robust against common image and video processing attacks and geometric attacks. Methods/ Statistical Analysis: The proposed algorithm is based on the features of a selected best algorithm by Agilandeeswari and Ganesan and its limitations. The advantages of the hybrid transform techniques of Non-subsampled Contourlet Transform, Discrete Wavelet Transform and Singular Value Decomposition are utilized for high robustness against common attacks. Finding: The features of angle invariance and distance invariability of Log Polar Transform and Inverse Log Polar Transform are used in the extraction process only to resist geometric attacks without affecting the imperceptibility of watermark and watermarked video. Application/Improvements: Modified Arnold Transformation is introduced to improve the security of the watermark. The experiment shows that the algorithm is extremely robust in terms of image and video processing, temporal, common attacks and geometric attacks covering rotation, scaling and translation attacks along with high imperceptibility and improved security.
Keywords: Geometric Attacks, Non-subsampled Contourlet Transform, Video Watermarking
