With the advancements in the field of digital image processing during the last decade, digital image data hiding techniques such as watermarking, Steganography have gained wide popularity. Digital image watermarking techniques hide a small amount of data into a digital image which, later can be retrieved using some specific retrieval algorithms to prove the copyright of a piece of digital infor...

Digital watermarking has been widely applied to solve copyright protection problems of digital media relating to illegal use or distribution. In the past few years, several gray-level image watermarking schemes have been proposed, but their application to color image watermarking schemes is scarce and usually works on the luminance or individual color channel. In this paper, a new color image w...

The digital revolution in digital image processing has made it possible to create, manipulate and transmit digital images in a simple and fast manner. The adverse affect of this is that the same image processing techniques can be used by hackers to tamper with any image and use it illegally. This has made digital image safety and integrity the top prioritized issue in today’s information explos...

The rapid increase of digitized media because of the proliferation of networked multimedia has created many issues like related to copyright protection, easily copying and transmitting the digital data. This has created the need for various techniques which helps to protect the digital media over the internet. Digital watermarking is one of the solutions. Digital watermarking is a technique whi...

The paper introduces the digital watermarking technology which is a data hiding technique that embeds a message into a multimedia work such as an image or text or other digital object. The proposed technique has several important applications; the majorly important is the digital copyrights protection. The digital watermarking system as any other data hiding technique has its own requirements t...

Watermarking of digital content is an imperative and interactive method for identification and protection of digital data. It allows veritable watermarks to be hidden in digital data for example image, audio, and video. Procedure of embedding and extracting of watermark from original image and watermarked image is complex. These include randomization of the watermark and selection of locations ...

The availability of bandwidth for internet access is sufficient enough to communicate digital assets. These digital assets are subjected to various types of threats. [19] As a result of this, protection mechanism required for the protection of digital assets is of priority in research. The threat of current focus is unauthorized copying of digital assets which give boost to piracy. This under t...

R.Charanya, T. Vijayan Abstract: In this Paper, a method of Information hiding & Piracy protection in Image processing is discussed. Visual cryptography & Digital watermarking helps in enables Information hiding, copyright & piracy protection. Here, a technique involving halftone visual cryptography along with watermarking is proposed to achieve visual cryptography via half toning. Digital wate...

Within information hiding technology, digital watermarking is one of the most important technologies for copyright protection of digital content. Many digital watermarking schemes have been proposed in academia. However, these schemes are not used, because they are not practical; one reason for this is that the evaluation criteria are loosely defined. To make the evaluation more concrete and im...
