Gödelization and SVD based image watermarking under wavelet domain

Abstract

In this digital era, with the ever growing size of multimedia database and digital media, there is a need for designing of robust methods to enhance the security of multimedia data against various attacks. One such popular technique is digital watermarking, and in this paper two different approaches for multimedia data hiding and copyright protection are implemented. Gödelization and Singular Value Decomposition techniques under frequency domain are implemented and compared. © 2013 Springer-Verlag.
