A Bit Level and Entropy based Blind Watermarking Scheme for Video Sequence using Random Frame Selection

Abstract

Digital video watermarking is the enabling technology to prove ownership of copyrighted material, to solve the problem of piracy and to detect the originator of illegally made copies. In this paper, to solve the authentication problem an effective, imperceptible and secure blind video watermarking algorithm is proposed which uses an encryption key to select the random frames of video in which watermark information is embedded uniformly throughout the video. To keep the algorithm imperceptible only few blocks on the basis of higher entropy are selected and watermarked using LSB technique. The performance of algorithm is tested using MATLAB software on video of "rhinos" and watermark image of 512 X 512. The experimental results show that the proposed scheme is highly imperceptible, less time consuming, more secure and highly robust against frame dropping & other manipulations.
