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

Affine Transformation Resistant Watermarking Based on Image Normalization

ABSTRACT

Geometric attacks are among the most challenging problems in present day watermarking. Such attacks are very simple to implement yet they can defeat most of the existing watermarking algorithms without causing serious perceptual image distortion. In this paper we propose a new public watermarking algorithm, which is robust to such attacks. This algorithm uses a normalized with respect to affine transformation representation of the imag ....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 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

Abstract—
Medical image is usually comprised of region ofinterest (ROI) and region of non interest (RONI). ROI is theregion that contains the important information from diagnosispoint of view so it must be stored without any distortion. Wehave proposed a digital watermarking technique which avoidsthe distortion of image in ROI by embedding the watermarkinformation in RONI. The watermark is comprised of patientinformation, hospital logo and message authentication code,computed using hash function. Earlier BCH encryption ofwatermark is ....etc

ROBUST DWT-SVD DOMAIN IMAGE WATERMARKING: EMBEDDING DATA IN ALL FREQUENCIES
Watermarking (data hiding) is the process of embedding data into a multimedia element such as image, audio or video. This embedded data can later be extracted from, or detected in, the multimedia for security purposes. A watermarking algorithm consists of the watermark structure, an embedding algorithm, and an extraction, or detection, algorithm. Watermarks can be embedded in the pixel domain or a transform domain. In multimedia applications, embedded watermarks shou ....etc

1.Introduction
 Information protection
 When dealing with information protection, we must distinguish between security and dependability.
 Security can be defined in terms of confidentiality, availability,integrity and authenticity .
 Dependability mostly concerns the computing system.
 It can be described as a composite of availability (of a service), reliability (continuity of service) and maintainability (ability to undergo modifications and repairs)
