ABSTEACT Digital watermarking is the process that imperceptibly watermarks the multimedia product with a specific watermark for the purpose of content authentication, data monitoring and tracking, and copyright protection. Amongst the applications, the most prominent usage of watermarking technique is helping in identifying the origins of different multimedia files and resolving ownership dispu...

Information hiding techniques have recently become important in a number of application areas. The information hiding scheme can be classified into two main application fields: steganography and watermarking. There is a considerable amount of published work in this field. However, little work addresses information hiding from the user's point of view. Potential problems, user requirements, eval...

The objective of this work is to develop a hardware-based watermarking system to identify the device using which the photograph was taken. The watermark chip will be fit in any electronic component that acquires the images, which are then watermarked in real time while capturing along with separate key. Watermarking is the process of embedding the watermark, in which a watermark is inserted in ...

The most important issues in video watermarking are invisibility of the watermark and the resilience of watermarking to attacks. The area of video watermarking has focused primarily on the problem of robustness to geometric attacks, while discounting the problem of more sophisticated attackers. So to improve the robustness of watermark for A new digital watermarking algorithm, for based on LDPC...

Copyright protection is a necessity for on-line media distribution e-services. Watermarking technology enables copyright protection for e-services but delays the packaging process and delivery. Instant delivery is a primary requirement for on-line businesses. The imperceptibility and robustness of watermarking has been studied extensively, but its impact on the performance of e-services, such a...

Copyright law is important in the media sector since an original creative work owner has exclusive right to consent, publish, broadcast, and even translate or modify their work. A growing number of digital copyright issues can be found behind widespread use multimedia technologies. Improvements must made away infringement prevention approach using watermarking. Zero-watermarking lately gained p...

The growth of computer networks has boosted the growth of the information technology sector to a greater extent. There is a trend to move from conventional libraries to digital libraries. Embedding a digital signal with information which cannot be removed easily is called ‘Digital Watermarking’. Visible watermarking is a type of digital watermarking used for protection of publicly available ima...

in this paper a wavelet-based logo watermarking scheme is presented. the logo watermark is embedded into all sub-blocks of the lln sub-band of the transformed host image, using quantization technique. extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. knowing the quantization step-size, dimensions of logo and the level of wavelet tra...

In this paper, we report results from comparative study on various related and relevant aspects of the digital watermarking such as image authentication techniques using fragile watermarking, fuzzy clustering and genetically inspired watermarking techniques for integrity verification. This is carried out with intent to develop an understanding of their working, contained challenges, possible at...

Digital watermarking is not a new name in the tech neology world but there are different techniques in data hiding which are similar to watermarking. In this paper we compare digital watermarking with other techniques of data hiding. Stenography, Fingerprinting, cryptography and Digital signature techniques are compared with watermarking. We need water marking for digital data security .It prov...
