Abstract

This paper presents a method for hiding watermarking signals in a gray level image, using a combination of genetic meta-heuristic algorithm and spread spectrum method in Discrete cosine transform field, initially the watermarking signal expands using Hadamard matrix, which increases security and facilitates the retrieval of the watermark signal. The image is then divided into 4 × 4 blocks and the Discrete cosine transform is performed on each block. For insertion of extended watermark signal using the Genetic Algorithm, blocks of the whole image are selected which is optimized based on NC, PSNR and SIM measurement parameters. Also in each selected block, the most important AC coefficient in JPEG quantized table is selected for the insertion of the watermark signal. In order to obtain the sensitivity of the proposed method, the sensitivity analysis is performed on the watermarking Interest coefficient α,and the best value is determined. The proposed method exhibits good resistance to deliberate and unintentional attacks for several sample images having different frequency properties than the conventional methods of randomly selecting blocks.
