Protecting Copyrights of Color Images using a Watermarking Scheme Based on Secret Sharing and Wavelet Transform
This paper presents a novel digital watermarking scheme for copyright protection against piracy of color images. Unlike traditional watermarking schemes that directly embed watermarks into host images, the scheme encodes the watermark prior to watermark embedding to improve tolerance to attacks. The process utilizes the secret sharing scheme with the feature extracted form the host image by the...
متن کاملA Robust Multiwavelet-Based Watermarking Scheme for Copyright Protection of Digital Images Using Human Visual System
The contemporary period of information technology facilitates simple duplication, manipulation and distribution of digital data. This enduringly, has insisted the rightful ownership of digital images to be protected efficiently. For content owners and distributors, there emerged a necessary concern in regard to the content authentication of digital images as well as copyright protection. A late...
متن کاملHuman Visual System Sentient Imperceptible and Efficient Wavelet-Based Watermarking Scheme for Copyright Protection of Digital Images
Contemporary information age facilitates easy duplication, manipulation and distribution of digital content. This has resulted in the necessity for safe guarding the rightful ownership of digital images. Copyright protection and content authentication of digital images have turned out to be a pressing problem to content owners and distributors. Digital watermarking offered an effective solution...
متن کاملWavelet-Based Robust Digital Watermarking Considering Human Visual System
In recent years, there have been many studies of digital watermarking as one of the way to protect the copyrights of digital content. It is required for digital watermarking method that the watermark is perceptually invisible and robust against various kinds of attacks. In this paper, we propose a digital watermarking method based on the noise masking effects and the HVS (human visual system). ...
متن کاملBlock-based discrete wavelet transform-singular value decomposition image watermarking scheme using human visual system characteristics
Digital watermarking has been suggested as a way to achieve digital protection. The aim of digital watermarking is to insert the secret data into the image without significantly affecting the visual quality. This study presents a robust block-based image watermarking scheme based on the singular value decomposition (SVD) and human visual system in the discrete wavelet transform (DWT) domain. Th...
