Fusion Framework for Robust and Secured Watermarking
This paper presents a robust and secure watermarking technique for digital image. To implement the technique, Discrete Wavelet Transform (DWT) is applied on cover image. Further on Low-Low (LL) sub-band of DWT, Discrete Cosine Transform (DCT) is applied which is followed by Singular Value Decomposition (SVD). To introduce the secure watermarking, watermark is secured using Arnold Transformation...
متن کاملRobust and High-Secured Watermarking System Using Zernike Moments
Watermarking is an effective technology that solves many problems within a digitization project. A high capacity data entrenching scheme based on precise and fast framework for the computation of Zernike moments (ZMs) is proposed in this paper. The high capacity is achieved by maximizing data entrenching size and improving the hiding ratio after dipping the inaccuracies in the computation of ZM...
متن کاملVisual Cryptography based Secured and Robust Digital Image Watermarking
Digital ImageWatermarking is a process of embedding a copy righted information inside the digital image such a way that intruder is not able to trace the information. In this paper a simple visual cryptography based robust digital image watermarking scheme is presented. Watermark Robustness is obtained by using repetition codes and Security of the watermark by visual cryptography. In this metho...
متن کاملA general framework for robust watermarking security
The analysis of the security of watermarking algorithms has received increasing attention since it has been recognized that the sole investigation of robustness issues is not enough to properly address the challenges set by practical applications. Such a security analysis, though, is still in its infancy, up to a point that a general agreement has not yet been reached even on the most fundament...
متن کاملOptimized Perceptual Quality, Robust and Highly Secured Randomly Scrambled Image Watermarking using 3-Level DWT Domain
In networks the content distribution through genuine channels needs the use of digital watermarks. The digital watermark is to make the content self-identifying i.e. to place the information within the content itself. Digital images are the significant vector for network communication. As 2D-image signals are non-stationary signal wavelet transform is more suitable to analyze this signal. This ...
