A new blind digital watermarking algorithm based on the chain code is proposed. The chain code is obtained by the characteristics of the original image -the edge contour. The feather can reflect the overall correlation of the vector image, and chain code expression can significantly reduce the boundary representation of the amount of data required. For the watermarking embedding, the original vector image is divided into sub-block images, and two bits of the watermarking information are embedded into sub-block images repeatedly by quantization. For watermarking extracting, the majority decision method is employed to determine the size of the extracted watermark. Experimental results show that the image quality is not significantly lowered after watermarking. The algorithm can resist the basic conventional attacks and has good robustness on the shear attacks.

The need to safeguard the property rights of multimedia content from unauthorized copying and the possibility to determine the true owners of the asset can be faced by resorting to efficient digital watermarking systems. This chapter presents a mathematical formulation to define a digital watermarking system and describes the general requirements to be satisfied, with more emphasis given to the aspects of security, robustness, and imperceptibility. After this general discussion, the two main classes of digital watermarking schemes, namely the spread-spectrum watermarking and the side-informed watermarking are explained by highlighting their main advantages and drawbacks. This analysis is completed by the description of a practical implementation of a digital image watermarking scheme. Finally, the use of watermarking systems in the framework of a DRM is deeply analyzed.

Digital image watermarking is an attractive research area since it protects the multimedia data from unauthorized access. For designing an efficient and robust digital image watermarking system, the trade-off among imperceptibility, robustness, capacity, and security must be maintained. Various studies regarding this concern have been performed to ensure these requirements by hybridizing different domains, such as spatial and transform domains. In this paper, we have presented an analytical study of the existing hybrid digital image watermarking methods. At first, we have given a standard framework for designing a hybrid method that ensures the basic design requirements of watermarking for various applications. After a brief literature review, we compared and analyzed the complexity of several existing hybrid methods in a tabular form. The limitations and applications of these methods are also highlighted. Finally, we summarized the challenges of the existing methods and concluded the study by giving future research directions.

This paper reviews the research status of digital image watermarking in the past decade. Considering there are too many publications about the digital image watermarking, we summarize main approaches and point out interesting parts of the researches. Multimedia watermarking technology offers advanced right away throughout the last several years. An electronic watermark is actually facts that are certainly imperceptibly and robustly inserted in the number data in ways that the idea is not taken off. Some sort of watermark commonly consists of information about the foundation, status, or perhaps receiver on the number data. In this review paper, certain requirements and apps intended for watermarking are usually reviewed. Purposes consist of copyright defense, data monitoring, and data pursuing. The fundamental concepts involving watermarking techniques are usually given and highlighted along with offered watermarking options for pictures, movie, audio tracks, text message files, along with advertising. Robustness and safety measures elements are usually mentioned in greater detail. Finally, several remarks are created around the cutting edge and possible potential trends inside watermarking technology.

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. This paper gives details of standard watermarking system frameworks and lists some standard requirements that are used in designing watermarking techniques for several distinct applications. The current trends of digital image watermarking techniques are also reviewed in order to find the state-of-the-art methods and their limitations. Some conventional attacks are discussed, and future research directions are given.

Digital image watermarking is an active research field since it provides protection, security, and authenticity of data. This paper presents development and implementation of a blind and robust watermarking application for ID images under a print-cam system. In the present case, the images are watermarked and printed on ID cards and then detected freehandedly with a smartphone camera. In order to design an efficient and robust image watermarking application, the attacks produced in print-cam processes, such as geometric distortions, must be resolved. Accordingly, the proposed watermarking approach is applied in the Fourier domain. Then, a frame-based projective rectification is integrated to deal with geometric distortions by using detection of Hough lines. Moreover, better robustness against print-cam watermarking attacks was achieved compared with the existing methods, and an Android application was designed and implemented based on the proposed scheme.


This paper speaks to various Digital Watermarking systems which allows a person to include unseen copyright see just as some other confirmation messages to pictures with the goal that it very well may be shielded from the unapproved get to. The principle point of paper is to investigate the examination of different digital picture watermarking schemes and it likewise exhibits that all these watermarking strategies gives picture watermarking full protection and sensible limit. Here hybrid Image watermarking procedure which takes the benefits of various transforms like DWT, DCT, SVD and Arnold Transform, which improves greater security and gives heartiness to the watermark. In this paper technique, picture is separated into a few gatherings of edges, and one of the casings is chosen where watermark will be implanted. Before embed watermark in a choose casing it will be pre-handled with Arnold Transform which will give security to it.

As Internet usage continues to grow, people are becoming more aware of the need to protect the display and presentation of digital documents. Digital watermarking offers a means to protect such documents. It works by embedding a piece of information into these documents – either visibly or invisibly – which can be detected or extracted from the document at a later stage to prove ownership of the document. This chapter will review, in detail, the process of digital image watermarking and will evaluate the different types of watermarks which may be used and the different techniques used to embed the watermarks. An examination of the domains used to embed the watermarks and some of the techniques used for detection of the embedded watermark are provided. Finally future trends within the area of digital watermarking are outlined.
