Digital Watermarks for Copyright Protection

2021

Digital watermarking is the process of embedding data to identify its owner or originator. It track the use of digital media and identifies the unauthorized use or access. Digital watermarking is embedding data’s in the form of text, video, audio, or images. There are two types of watermark classificationinvisible watermark and visible watermark. In invisible watermarking, information is added as digital data to audio, video, and images whose information that are not visible. While visible watermarking, the embedded information is visible in the form of a text or a logo. The data contained in the watermark includes the recipients of each copy so that any information that gets leaked can be traced back very easily. This tracing can be identified with the help of algorithms. Nowadays organizations are developing new digital watermark types in the form of noise. These noises are a type of digital watermark that assigns random data to exist electronic data. We have discussed digital wat...

Digital Watermarking for Protection of Intellectual Property

Concepts, Methodologies, Tools, and Applications

Digital watermarking techniques have been developed to protect the copyright of media signals. This chapter aims to provide a universal review and background about the watermarking definition, concept and the main contributions in this field. The chapter starts with a general view of digital data, the Internet and the products of these two, namely, the multimedia and the e-commerce. Then, it provides the reader with some initial background and history of digital watermarking. The chapter presents an extensive and deep literature review of the field of digital watermarking and watermarking algorithms. It also highlights the future prospective of the digital watermarking.

ABSTRACT Multimedia assets have to be marked steganographically to protect the rights of the owner. Digital watermarks are inserted as a bit sample or digital signal into the data with an embedding algorithm using a secret key. The embedded information is hidden (in low-value bits or least significant bits of picture pixels, or in frequency space) and connected inseparably with the data. For the optimal application of watermark technology a trade-off has to be made between competing criteria such as robustness, non-perceptibility, non-detectability, and security. Most watermark algorithms cannot tackle to attacks. Even friendly attacks in form of usual file modifications can destroy very easily the watermark or falsify it.

Watermarking for Copyright Protection of Digital Images

2014

Nowadays, a chief problem encountered by content providers and owners is the protection of their material. They are apprehensive about copyright protection and further forms of exploitation of their digital content. The ease by which digital information can be duplicated and distributed has led to the need for effective copyright protection tools. Diverse techniques including watermarking have been introduced in effort to tackle these increasing concerns. Recently digital watermarking technology has emerged as an effective solution for protecting the digital content from unauthorized copying. A wide variety of watermarking techniques have been proposed by researchers for the copyright protection of digital images. An extensive review of the prevailing literature in watermarking of digital images for copyright protection is presented along with the classification. In addition, a concise introduction about digital watermarking is presented along with its properties, applications and t...

Safeguarding the Digital Contents: Digital Watermarking

DESIDOC Journal of Library & Information Technology, 2009

Digital watermarks are one of the tools which helps to make the distribution of digital material more secure. It is a kind of digital signal or pattern hidden directly in digital content. The paper deals with the multi-faceted aspects of digital watermarking (DWM) technology. It also discusses the need for DWM with the properties like robustness, security, invertibility, transparency, complexity, capacity, and verification. The key aspects are given with the solutions for DWM. Few companies involved in DWM activities are discussed with the technique of embedding with different types of watermarks. It discusses tool and techniques for images, text, and other applications of DWM. The possible attacks on DWM and the organisations involved in developing standards for it are described. It has been concluded that the protection of individual rights is a must, and deeper understanding of the DWM will lead to the design of more reliable systems for safeguarding digital contents.

Intellectual property protection systems and digital watermarking

Optics Express, 1998

Adequate protection of digital copies of multimedia content -both audio and video -is a prerequisite to the distribution of this content over networks. Until recently digital audio and video content has been protected by its size: it is difficult to distribute and store without compression. Modern compression algorithms allow substantial bitrate reduction while maintaining high-fidelity reproduction. If distribution of these algorithms is controlled, cleartext uncompressed content is still protected by its size. However, once the compression algorithms are generally available cleartext content becomes extremely vulnerable to piracy. In this paper we explore the implications of this vulnerability and discuss the use of compression and watermarking in the control of piracy.

Robust Digital Watermarking Techniques for protecting copyright Applied to Digital Data: A Survey

2021

The colossal prominence of the World Wide Web in the mid 1990's shown the business capability of offering media assets through the computerized networks. Since business intrigues look to utilize the advanced organizations to offer computerized media revenue driven, they have a solid interest in ensuring their proprietorship rights. Since the danger of utilizing media data, advanced fabrications, and unapproved sharing (robbery) of computerized content has expanded among content makers, merchants and clients. Today mixed media data theft alone has exposed all the enterprises to multi-billion income misfortunes. Customary advanced substance security methods, for example, encryption and scrambling, alone can't give satisfactory insurance of copyrighted substance, in light of the fact that these advances can't ensure computerized content whenever they are decoded. One approach to debilitate illicit duplication is to embed data known as watermark, into possibly weak informati...

Digital Watermarking and Its Impact on Intellectual Property Limitation for the Digital Age

IGI Global eBooks, 2011

Digital media like audio, video, images and other multimedia documents can be protected against copyright infringements with invisible, integrated patterns. Such methods are based on steganography and digital watermarking techniques. Most watermarks are inserted as a plain-bit or adjusted digital signal using a key-based embedding algorithm. The embedded information is hidden (in low-value bits or least-significant bits of picture pixels, frequency or other value domains) and linked inseparably with the source data structure. For the optimal watermarking application, a trade-off between competing criteria like robustness, nonperceptibility, non-detectability and security have to be made. Most watermarking algorithms are not resistant against all attacks, and even friendly attacks like file and data modifications can destroy the watermark very easily. This paper gives an overview about the basic ideas of watermarking, application for e-business, problems and limitations.
