| Summary: | A novel secure and robust image watermarking technique for color images is presented in this paper. Besides
robustness and imperceptibility (which are the most important requisites of any watermarking scheme), there
are two other challenges a good watermarking scheme must meet: security and capacity. Therefore, in devising
the presented scheme, special consideration is also given to above-mentioned requirements. In order to do so,
principal component analysis is involved to enhance imperceptibility and the unique utilization of singular
value decomposition is done to achieve better performance in regard to capacity and robustness. Finally, a
novel method is proposed to select constituents of an image for watermark embedding, which further improves
the security. As a consequence, four essential requisites of a good watermarking scheme are achieved as
visible from experimental results. To measure the behavior of presented watermarking scheme, a number of
experiments were conducted by utilizing several color images as host images and as watermarks. The presented
technique is compared with the latest available watermarking techniques and attained better results than
them. |
