Abstract:

 

The major issues in most watermarking schemes are   security, reliability, and robustness against attacks. To achieve these   objectives in a watermarking algorithm, the selection of a scale factor to   embed the watermark into the host image is a challenging problem. In this   paper, a block singular value decomposition (SVD)-based reliable, robust,   secure, and fast watermarking scheme is proposed that uses particle swarm   optimization (PSO) in the selection of the scale factor. SVD is applied here   on the nonoverlapping blocks of LL  wavelet  subbands. Selected singular   values of these blocks are modified with the pixel values of the watermark image.   Selected locations of these singular values increase security. In addition,   the scale factor using PSO for embedding the watermark increases the   robustness and imperceptibility of the proposed scheme. Direct embedding of   the watermark image into the host image and the use of block-SVD makes the   scheme faster. Comparative analysis with an existing algorithm shows that   the proposed technique performs well during most types of noise attacks and   removes the diagonal line problem present in the extracted watermark image.
