Watermarking

been growing interest in developing effective techniques to discourage the unauthorized duplication of digital data. Digital watermarking is the process of embedding information into a digital signal in a way that is difficult to remove. Protection of digital multimedia content has become an increasingly important issue for content owner and service providers. Watermarking is identified as a major means to achieve copyright protection. Due to the rapid and extensive growth of electronic publishing

Watermarking has become very important since 1999. Audio watermark is a copyrighted production that is embedded with information of the owner. Some people thought the sound change was from compression but it is the sound from the watermark. Most companies have actually dropped digital rights management and started using watermarks. Digital rights management infringe on the consumer's right to fair use. Without fair use it doesn’t find its way to the public domain, which makes it hard for generations

intellectual property rights problem has become a very important issue. Digital watermarking is now drawing attention as a new method of protecting multimedia content from unauthorized copying. Over the past two decades, many digital watermarking algorithms have been developed, each with its own advantages and disadvantages. The main aim of this paper is to present a survey report of recently done work in audio watermarking fields. INTRODUCTION Technological advances in computing, communications, consumer

Watermarking is the process of hiding digital data in a carrier

The rapid invention going in internet usage has resulted in the media ownership and attention towards intellectual property rights among internet users. In this paper, a Multiwavelet Transform (MWT) based video encoding is proposed. Video watermarking is the practice of inserting an encode information known as the watermark, into an original video in an imperceptible approach. The watermark converts or represents information that can protect the watermarked video, typically identifying the source

CONTROLLED CONTENT DISTRIBUTION IN PEER-TO-PEER NETWORKS Amna Qureshi Controlled Content Distribution in Peer-to-Peer Networks Research Problem: Centralized fingerprinting mechanism has an encumbrance of computational overheads and high communication bandwidth costs. Central repository of authenticating data has also raised concerns over the loss of privacy and potential misuse of biometric data. For instance, biometric data stored at a central repository can be used to track individuals

Digital Watermarking technique is used to hide a secret or personal message to protect a products copyright or to demonstrate data integrity. To provide double protection, after the watermarking process, the watermarked image tends to go through an encryption process using CHAKRA – symmetry key encryption algorithm

INTRODUCTION 1. Introduction Information is becoming widely available via global networks. These connected networks allow cross-references between databases. The advent of multimedia is allowing different applications to mix sound, images, and video and to interact with large amounts of information (e.g., in e-business, distance education, and human-machine interface). The industry is investing to deliver audio, image and video data in electronic form to customers, and broadcast television

issues to be dealt with and tremendous work is going on in this direction round the globe. Digital watermarking and fingerprinting have emerged as fundamental technologies to cater to DRM issues. These technologies have been found to be of prominent use in content authentication, copy protection, copyright control, broadcast monitoring and forensic applications. Various requirements of a digital watermarking system include Imperceptibility, Robustness, Security, Payload and Computational complexity. The

Digital Watermarking has proved to be a good solution to tackle these problems. It discourages the copyright violation and help to determine the authenticity and ownership of the data. A Digital image watermarking systems have been proposed as an efficient means for copyright protection & authentication of digital image content against unintended manipulation (spatial chromatic). Watermarking techniques tries to hide a message related to the actual content of the digital signal, watermarking is used
