Enhancement in reversible watermarking with certain techniques

Abstract

Watermarking technique has been invoked as a medium for the newlineprotection of all Intellectual Property Rights (IPR) of multimedia-based newlineinteractive program substances. The multimedia document information s newlinedigital nature allows the information to be duplicated, diffused, modified and newlinetransformed easily. This sensitizes the need for a novel system for copyright newlineprotection, protection against duplication and authentication of subject newlineinformation. Moreover, the insufficiency projected by the current copyright newlinerules while dealing with digital information has led to several emerging new newlinecopyright restriction and protection systemsOne such novel copy right protection method is the process of embedding information into digital multimedia content itself. Thus, it newlinefacilitates the feature extraction of information or detecting similar newlineinformation content for preventing copyright control. The developed newlinemethodology embeds the watermark information into the digital nature of newlinedata in such a way that it is indistinguishably fused into the data itself. As a newlinerequirement arises, such watermark information can be extracted to prove its newlineownership and trace the distribution of the watermarked work through the newlineentire digital network system. newline newline
