In this paper, we propose a method for copyright protection by spread spectrum watermark embedding in Fourier domain. Here we use block based two dimensional Fast Fourier transformation and embed the watermark by modifying the co-efficents in the high frequency band of the cover image. The watermark image to be embedded is scrambled using Arnold transformation and the scrambled watermark is embedded,which encrypts the watermark image to be embedded. Correlation based method is used in extraction of the embedded watermark. The proposed watermarking algorithm proves to have bet
