Watermarking Algorithm using Genetic Algorithm and HVS

In this work, a watermarking algorithm is proposed using Genetic algorithm and discrete wavelet transformation. The algorithm proposed is to improve both robustness and fidelity of the watermarked image. Fuzzy Inference system is used to determine the embedding strength based on HVS properties of the image. To test the robustness different attacks are performed and the NC (Normalized cross corr...

A Digital Watermarking Scheme Based on Singular Value Decomposition and Micro-genetic Algorithm

A novel robust digital image watermarking scheme based on singular value decomposition (SVD) and micro-genetic algorithm (micro-GA) is proposed in this paper. In an SVD-based watermarking scheme, the singular values of the cover image are modified to by considering multiple scaling factors to embed the watermark image. Determining the proper values of scaling factors is not an easy task. Here w...

Digital Video Watermarking with a Genetic Algorithm

Due to the explosion of data exchange on the Internet and the extensive use of digital media, it has been of intense interest to digital data owners in multimedia security and multimedia copyright protection. In this paper, a comprehensive approach for protecting and managing video copyrights with watermarking techniques is introduced. We propose a novel digital video watermarking scheme based ...

Genetic algorithm for fragile audio watermarking

A novel genetic-concept-based algorithm is proposed for fragile audio watermarking to reduce the distortion of least significant bits substitution and consequently improve the peak signal-to-noise ratio (PSNR) and increase the payload of results. The result of testing shows that in comparison with ordinary substitution techniques and other presented techniques, the payload is considerably incre...
