Digital Watermarking : Techniques , Applications , Attacks

2014

Due to the rapid evolution in internet technology and high speed networks the use of digital data has been increased. Digital data such as audio, video and images are easily created, copied, processed, stored and distributed among the users. To ensure security and protection of digital data new technology has been developed called as a digital watermarking. Digital watermarking is a technology which embeds additional information in the host image to ensure security and protection of the digital data without effecting original data. The purpose of digital watermarking is not to restrict use of digital data but it can be provide copyright protection and authentication against unauthorized uses. In this paper detail study of watermarking definition, concept and the main contribution of watermarking process in which watermarking should be used, features, techniques, Application, challenges and performance metrics of watermarking and comparative analysis of watermarking techniques are in...

A Survey on Digital Watermarking and its Application

International Journal of Advanced Computer Science and Applications

Digital communication plays a vital role in the world of Internet as well as in the communication technology. The secrecy of the communication is an essential part of passing the data or information. One noticeable technique is Digital Watermarking. Copyright owners seek methods to control and detect such reproduction, and henceforth research on digital product copyright protection has significant practical significance for E-commerce & E-Governance. In this paper, a survey on some previous work done in watermarking field is presented. Experimentally evaluated algorithms are collected to focus on the wide scope of encrypted digital watermarking for data transmission security and authentication.

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.

A SURVEY ON MODERN TRENDS IN DIGITAL WATERMARKING

National Conference, 2012

Digital Watermarking is a relatively new field for researchers, where the main objective is to hide the important information. The visibility of the information depends on the application requirements, which means the information can be visible or invisible. The explosion in the internet technology has posed the challenge in front of the researchers that how to protect copyright of an individual's creation. The absence of copyright information in the digital data may lead to the loss of revenues. The main requirement of any watermarking technique is that the digital watermark that is embedded with the original data should be inseparable. Many researchers have proposed techniques for digital watermarking that proved to be more robust than the existing approaches. In this paper, we have discussed the watermarking requirements, techniques and applications of watermarking.

An Art to Protect Originality of Digital Data: Digital Watermarking

2017

The rapid development of digital image processing Researchers used huge volume of data like medical image, satellite image, video image, digital image etc these data are retrieve through digital and electronic media. But subsequently digital information undergo from copyright and integrity violations problem. Digital watermark play a crucial role to resolve copy rights and ownership violation of digital information. Recently number of watermarking scheme has been proposed but towards more imperceptibility and robustness of host image at receiving is need to be improved. This paper gives a bird’s eye over recent research and different methodology of watermarking scheme.

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: A Tutorial Review

The growth of high speed computer networks and that of Internet, in particular, has explored means of new business, scientific, entertainment, and social opportunities. Ironically, the cause for the growth is also of the apprehension -use of digital formatted data. Digital media offer several distinct advantages over analog media, such as high quality, easy editing, high fidelity copying. The ease by which a digital information can be duplicated and distributed has led to the need for effective copyright protection tools. Various software products have been recently introduced in attempt to address these growing concerns. It is done by hidding data (information) within digital audio, images and video files. One way such data hidding is digital signature, copyright label or digital watermark, that completely characterizes the person who applies it and, therefore, marks it as being his intellectual property. Digital Watermarking is the process that embeds data called a watermark into a multimedia object such that watermark can be detected or extracted later to make an asertion about the object. Watermarking is either "visible" or "invisible". Although visible and invisible are visual terms watermarking is not limited to images, it can also be used to protect other types of multimedia object. This work is a tutorial review of the digital watermarking techniques appreared in the literature.

Digital Watermarking: Applications, Techniques and Attacks

International Journal of Computer Applications, 2012

As information transmission technology progresses, the technology to protect data from unauthorized users also needs to be enhanced. Data can be plagiarized, modified, deleted etc without proper authentication and authorization. Various security mechanisms have evolved that enhances the security of digital media. Each technology to be applied successfully should ensure a balance between the three pillars of security; confidentiality, integrity and availability. Digital watermarking is one such technique. It is a mechanism to monitor the digital media with the help of information residing within the content itself. To put it simply, digital watermarking is embedding of information into source content that can be detected and extracted. Digital watermarking can be applied to media like text, audio, image, video etc. This paper provides a comprehensive idea behind this technology and its usage.
