Abstract

The extension & exp1oration of the Internet has intermittent1y increased. Due to this, the avai1abi1ity and accessibi1ity of digita1 data such as audio, images & videos have incremental growth. Digita1 watermarking is a techno1ogy being deve1oped to assure & faci1itate data authentication, copyright protection & security of digita1 media.
