Abstract
Digital watermarking is the process of possibly irreversibly embedding information into a digital signal. The signal may be audio, pictures or video, for example. If the signal is copied, then the information is also carried in the copy,An important application of invisible watermarking is to copyright protection systems, which are intended to prevent or deter unauthorized copying of digital media

In this proposed algorithm, according to the size of the image we have to multiply the hadamard coefficient(Hn).In fut ....etc

Abstract
Watermarking, which belong to the information hiding field, has seen a lot of research interest recently. There is a lot of work begin conducted in different branches in this field. Steganography is used for secret conmunication, whereas watermarking is used for content protection, copyright management, content authentication and tamper detection. In this paper we present a detailed survey of existing and newly proposed steganographic and watenmarking techniques. We classify the techniques based on different domains in which ....etc

Abstract
Digital watermarking technique emerged as a tool for protecting the multimedia data from copyright infringement. In digital watermarking an imperceptible signal is embedded into the host image, which uniquely identifies the ownership. In the proposed algorithms, DNA sequence is used as a digital watermark, as the DNA sequences are unique and difficult to copy. This paper proposes two algorithms namely content based watermark algorithm using DNA sequence (CBDNA) and user specified watermark algorithm using D ....etc

ABSTRACT
In This Seminar An adaptive watermarking capacity analysis in the spatial domain and wavelet domain has to be present. The relationship between the watermarking capacity and the watermark detection error rate is also discussed. The discussion of watermark detection error rate will help us finding the ways to embed more watermark messages while keeping an acceptable detection error rate, it is useful for the design of the general algorithms of watermarking and detection. The watermarking system is analyzed based on the channel capacity ....etc

DIGITAL IMAGE TRACING BY SEQUENTIAL MULTIPLE WATERMARKING
Abstract
The possibility of adding several watermarks to the same image would enable many interesting applications such as multimedia document tracing, data usage monitoring, and multiple property management. In this paper, we present a novel watermarking scheme, which allows inserting and reliably detecting multiple watermarks sequentially embedded into a digital image. The proposed method, based on elementary linear algebra, is asymmetric, secure under pr ....etc

ABSTRACT

One of the biggest technological events of the last two decades was the invasion of digital media in an entire range of everyday life aspects. Digital data can be stored efficiently and with a very high quality, and it can be manipulated very easily using computers. Furthermore, digital data can be transmitted in a fast and inexpensive way through data communication networks without losing quality. Digital media offer several distinct advantages over analog media. The quality of digital audio, im ....etc

Digital Image Watermarking


INTRODUCTION

The development of effective digital image copyright protection methods have recently become an urgent and necessary requirement in the multimedia industry due to the ever-increasing unauthorized manipulation and reproduction of original digital objects. The new technology of digital watermarking has been advocated by many specialists as the best method to such multimedia copyright protection problem. Its expected that digital watermarking will have a wi ....etc

1. Abstract
In recent time watermarking technique becomes a potential solution for copyright protection, authentication and integrity verification of digital media. Among the widely used watermarking techniques, spread spectrum modulation based method becomes appealing due to its inherent advantage of greater robustness and is used widely for various applications. Some watermarking applications, for example, digital television broadcasting, internet protocol television (IP-TV), etc. essentially demand development of ....etc
