In this paper, a robust watermarking scheme for digital video sequence which is based on Entropy concept and Hadamard transformation technique is proposed. The proposed technique can hide an entire image or pattern as a watermark directly into the original video sequence. Hadamard transformation is used for converting cover video from spatial domain to transform domain in order to reduce the computational complexity of the proposed algorithm. Similarly for preserving the quality of the digital video, the entire video blocks are not altered for embedding. Instead only few blocks are selected and used based on the size of the watermark and information content of the video block. Entropy concept is used for selecting those video blocks. The proposed algorithm is tested with rugby video sequence containing 209 frames and watermark of size 64x64 using MATLAB software. The experimental results show that the proposed scheme is robust to random noise addition attacks such as Salt and Pepper, Gaussian, Poisson and Speckle.

“…The digital cosine transformation is applied to each 8*8 block of original image to get the DC coefficient then embed the PN sequence and then apply the inverse discrete cosine transformation on DC component to reconstruct the watermarked image. It provides good visual perception and robust against common attacks.Yasunori Ishikawa, Kazutake Uehira, and Kazuhisa Yanaka proposed an "Illumination Watermarking" technology with which the images of objects without copyright protection can contain invisible digital watermarking [20].

As a novel watermarking algorithm is required to protect copy rights of digital data entropy based robust watermarking scheme using Hadamard transformation technique is proposed in this paper. The proposed technique can hide an entire image or pattern as a watermark directly into the original image. As the quality of the image is to be preserved the entire image is not altered for embedding, instead few blocks are used based on the size of the watermark and information content of an image block. To reduce the computational complexity of the proposed algorithm Hadamard transformation is used for converting cover image from spatial domain to transform domain. The proposed algorithm is tested with Lena grey scale image of size 256x256 and watermark of size 64x64 using mat lab software. The experimental results show that the proposed scheme is robust to random noise addition attack, resize attack and cropping attack.

Watermark is the copy deterrence mechanism used in the multimedia signal that is to be protected from hacking and piracy such a way that it can later be extracted from the watermarked signal by the decoder. Watermarking can be used in various applications such as authentication, video indexing, copyright protection and access control. In this paper a new CDMA (Code Division Multiple Access) based robust watermarking algorithm using customized 8 × 8 Walsh Hadamard Transform, is proposed for the color images and detailed performance and robustness analysis have been performed. The paper studies in detail the effect of spreading code length, number of spreading codes and type of spreading codes on the performance of the watermarking system. Compared to the existing techniques the proposed scheme is computationally more efficient and consumes much less time for execution. Furthermore, the proposed scheme is robust and survives most of the common signal processing and geometric attacks.
