With the growth and advances in digital communication technologies, digital images have become easy to be delivered and exchanged. These forms of digital information can be easily copied and distributed through digital media. These concerns motivated significant re‐ searches in images watermarking [1]. New progress in digital technologies, such as com‐ pression techniques, has brought new chall...

In modern times, the rapid growth of the Internet has made copyright protection of digital contents a critical issue. A Digital Rights Management (DRM) system is aimed at protecting the high-value digital assets and controlling the distribution and utilization of those digital assets. Watermarking technologies are being regarded as a vital mean to proffer copyright protection of digital images....

Digital watermarking is the process of embedding information into a digital signal. The main issues to be considered during the watermark are robustness and fidelity. Robustness implies the strength of the watermark against various image processing attacks. The fidelity is used to determine the quality of the image after embedding the watermark. The techniques of digital watermarking are based ...

Digital watermarking is a method which is used to verify texts, image, video etc. Watermarking Technique is not only used for Authentication, it’s also used for security, image protection, rights of documents. In this perspective experiment we used edge detection technique in watermarking for the purpose of highly authentication of image. Here we used combined approach of LSB-DCT watermarking f...

Digital watermarking is the process to hide digital pattern directly into a digital content. Digital watermarking techniques are used to address digital rights management, protect information and conceal secrets. An invisible non-blind watermarking approach for gray scale images is proposed in this paper. The host image is decomposed into 3-levels using Discrete Wavelet Transform. Based on the ...

Digital Image watermarking is the process that embeds data called watermark in to multimedia object such that the watermark can be extracted or detected to make an assertion about the object. Watermarking is either “visible” or “invisible”. The growth of high speed computer networks and internets, in particular, explore the means of new business, scientific, entertainment and social opportuniti...

Digital watermarking is the process of embedding information into a noise-tolerant digital signal such as image or audio data to easily identify the copyright ownership of the media. Such information is embedded for many different purposes, such as copyright protection, source tracking, piracy deterrence, etc., and therefore it shall be embedded in a way that makes it difficult to be removed. T...

In digital watermarking, a watermark is embedded into a cover image in such a way that the resulting watermarked signal is robust to certain distortion caused by either standard data processing in a friendly environment or malicious attacks in an unfriendly environment. This work provides Digital image watermarking based on Fractional Fourier transform and two dimensional fast Fourier transform...

Digital watermarking is the act of hiding a message related to a digital signal (i.e. an image, song, video) within the signal itself. It is a concept closely related to steganography, in that they both hide a message inside a digital signal. Watermarking has a number of uses in security, authentication and registration purposes. Image Watermarking is a widely sought after research area and man...

Digital Image Watermarking is used for copyright protection of digital information. With the widespread of internet, the intellectual properties are accessible and manipulated easily. It demanded to have different ways to protect data. Digital watermarking provides a viable and promising solution. In this paper, we have described about the three different watermarking techniques (LSB, DCT, DWT)...
