digital watermarking is a process by which a user-specified
signal is hidden or embedded into another signal , for
example digital content such as electronic documents, images,
sounds and video [2]. The use of digital video applications
such as video-conferencing, digital television, digital cinema,
distance learning, videophone, and video-on-demand has
grown very rapidly over the last few years. Today it is much
easier for the digital data owners to transfer multimedia data
over the internet, and hence the data could be perfectly
duplicated and rapidly redistributed on a large scale. Thus, the
importance of copyright protection for multimedia data has
become more critical. Digital watermarking is an effective way
to protect the copyright of multimedia data even after its
transmission there is urgent demand for techniques to protect
the original digital data and to prevent unauthorized
duplication or tampering.
