Digital Watermarking Technology in Different Domains
Due to high speed computer networks, the use of digitally formatted data has increased many folds.The digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. Digital Watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .Di...
متن کاملRobust and Blind Spatial Watermarking In Digital Image
A robust, computationally efficient and blind digital image watermarking in spatial domain has been discussed in this paper. Embedded watermark is meaningful and recognizable and recovery process needs only one secret image. Watermark insertion process exploits average brightness of the homogeneity regions of the cover image. Spatial mask of suitable size is used to hide data with less visual i...
متن کاملCombinational image watermarking in the spatial and frequency domains
In order to provide more watermarks and to minimize the distortion of the watermarked image, a novel technique using the combinational spatial and frequency domains is presented in this paper. The splitting of the watermark image into two parts, respectively, for spatial and frequency insertion relies on the user’s preference and data importance. Experimental results provide the comparisons whe...
متن کاملComparative Analysis of Blind Digital Image Watermarking Utilising Dual Encryption Technique in Frequency Domains
Piracy in the presence of internet and computers proves to be a biggest jolt to the concerned industry. To reduce the piracy and duplicity of the images, digital watermarking technique is having an edge over the other available techniques. In this paper, a blind digital watermarking algorithm is presented which is robust enough to resist the watermark against the attacks. The algorithm exploits...
