Abstract : Data authentication is one of the primary requisites in present day communication systems. In image processing, data authentication is implemented by using watermarking techniques. Nevertheless, whatever be the technique of watermarking, one of the important factors to be considered is robustness. In this paper we discuss about a novel robust method for digital watermarking in spatial domain. The method deals with an image in the spatial domain which is watermarked at different intensity subsections. Further, we have analyzed the performance of the proposed method by implementing the method using Verilog HDL Matlab. A comparison of the proposed novel spatial domain method with the frequency domain method is also given here. We have implemented a frequency domain DCT/IDCT based digital watermarking as in [1] and [2]. We also compare the PSNR that can be obtained using the proposed spatial domain watermarking and the DCT/IDCT based watermarking. © 2010 IEEE.
