SYNOPSIS

I have selected final year major seminar entitled An Algorithm for Digital

Watermarking of Still Images For Copyright Protection by Jahnvi Sen,

A.M.Sen, and K.Hemachandran published in journal Indian Journal of

Computer Science and Engineering Feb-March 2012 ,under the guidance of

Ms. Archana Phutela.

Abstract: The rapid expansion of the Internet has rapidly increased the

availability of digital data such as audio, images and videos to the public andfile sharing has become very convenient. As such, the problem of protecting

multimedia information, the issues of copyright has gained interest of

researchers. Owners are concerned about protecting any illegal duplication oftheir data or work. Protection of intellectual property is very important because

digital multimedia content can be copied and distributed quickly, easily,

inexpensively, and with high quality and precision. Watermarking has been

accepted as a complementary technology to multimedia encryption, providing

some additional level of protection of intellectual property rights. Here wepresent an overview of digital watermarking and the range of applications that

could benefit from applying digital watermarking technology. We propose asimple algorithm for watermarking of an image. The algorithm enables the basic

requirements of watermarking and there is future scope to incorporate additional

security and robust natures.
