Digital Watermarking with a New Algorithm
Everyday millions of data need to transmit through a distinct channel for various purposes; as a result there is a certain chance of third person interruption on that data. In this regards digital watermarking is one of the best solution. This paper proposes a new embedding algorithm (NEA) of digital watermarking. The algorithm is performed for digital image as data. The performance is compared...
متن کاملA New Digital Audio Watermarking Algorithm
In this paper a new digital audio watermarking algorithm is proposed based on B-spline approximation. The algorithm takes the advantage of non-uniform B-spline wavelet, namely, the number of low-frequency components can be arbitrarily selected, so, it is very flexible. Meanwhile, it avoids the complex calculations of non-uniform B-spline wavelets. The simulation experiments show that this algor...
متن کاملDigital 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 ...
متن کاملA New Hybrid DWT-DCT Algorithm for Digital Image Watermarking
Watermarking is the requirement of today‟s digital media. Embedding of watermark provides security against piracy & attacks .Watermarking is also useful for provide owner identification to digital media. Inthis Research papera new algorithm, for digital image, based on Hybrid DWT-DCT Transformation is proposed. A host image (grey scale) is initially DWT transformed up to 3-level.Thencomputation...
متن کاملA Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
