Electronic publishing has gained importance with the widespread use of Internet. It involves transmission of digital data in bulk from one place to another. It brings various threats to the data in form of illegal copying, redistribution of copyright contents and forgery. Watermarking provides authentication and copyright protection to the multimedia contents over the Internet. This paper prese...

In this paper new algorithm proposed for digital watermarking using Least Significant Bit (LSB) .LSB already used but there is a slightly effect on the image. The above algorithm is using LSB & second LSB bit. Here we used binary value of watermark text in LSB, and in place of second LSB, the inverse of their correspond LSB bit. The proposed algorithm is flexible depending on the length of wate...

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...

A new digital watermarking technique for images that are sensitive to blocking artifacts is presented. Experimental results show that the proposed MDCT based approach produces highly imperceptible watermarked images and is robust to attacks such as compression, noise, filtering and geometric transformations. The proposed MDCT watermarking technique is applied to fingerprints for ensuring securi...

We present a so-called fuzzy watermarking scheme based on the relative frequency of error in observing qubits in a dissimilar basis from the one in which they were written. Then we discuss possible attacks on the system and speculate on how to implement this watermarking scheme for particular kinds of messages (images, formated text, etc.).

In this paper, we propose watermark design patterns to model the characteristic of digital watermark in electronic commerce applications. A watermark design pattern preserves the properties of a digital watermark in binary tree representation. Applying the survey results and characteristics of existing watermarking techniques, watermark design patterns for four media data video, image, audio, a...

In today’s digital world securing different forms of content is very important in terms of protecting copyright and verifying authenticity. One example is watermarking of digital audio and images. We believe that a marking scheme analogous to digital watermarking but for documents is very important. In this paper we describe the use of laser amplitude modulation in electrophotographic printers ...

Security of digital products (audio, video, image, and text) on the internet is very essential these days, for these digital watermarking techniques are used. Digital watermarking is the process of embedding data into digital multimedia content. This is used to validate the reliability of the content or to recognize the identity of the digital content's owner. Sophisticated watermarking techniq...

This paper discuss natural language watermarking, which analyzes patterns inside sentences of a given natural language text document, in order to embed individual watermark messages. The term ”natural language watermarking” stands for the process of the embedding of watermark messages into a text document, using natural language components as the carrier, in such a way that the modifications ar...
