Abstract

Digital watermarking using advanced techniques in spectral domain and pictorially showing the comparisons of importance and efficiency of discrete fourier transform and discrete cosine transform in spectral domain of digital watermarking is mainly reflected in this paper. The proposed technique will produce more efficient output but under certain specifications. The comparisons of various transforms are essentially performed and contemplated for better results .The features of the digital world lead to economical changes such as cheap distribution and also serious risks in simplifying unauthorized copying and distribution. So, there is an immediate requirement for a well-established and advanced technique for digital watermarking.
