Abstract
Advances in technologies facilitate the end users to carry out unauthorized manipulation and duplication of multimedia data with
less effort. Because of these advancements, the two most commonly encountered problems are (1) copyright protection and (2)
unauthorized manipulation of multimedia data. Thus a scheme is required to protect multimedia data from those two above said
problems. Digital Watermarking is considered as one of the security mechanisms to protect copyrights of multimedia data. The
literature review reveals that the calculation of scaling and embedding parameters are not completely automated. In order to
automate the procedure of calculating scaling and embedding parameters the computational intelligence need to be incorporated
in the watermarking algorithm. Moreover the quality of the watermarked images could also be preserved by combining
computational intelligence concepts. Thus watermarking schemes utilizing computational intelligence concepts could be called as
intelligence based watermarking schemes and it is presented in this paper in detail.
