摘要：Generally, The sending process of secret information via the transmission channel or any carrier medium is not secured. For this reason, the techniques of information hiding are needed. Therefore, steganography must take place before transmission. To embed a secret message at an optimal positions of the cover image, using the developed particle swarm optimization algorithm (Dev.-PSO) to do that purpose in this paper. The main aim of (Dev.-PSO) algorithm is determining an optimal paths to reach a required goals in the specified search space based on disposal of them, using (Dev.-PSO) algorithm produces the paths of a required goals with most efficient and speed. an agents population is used in determining process of a required goals at search space for solving of problem. The (Dev.-PSO) algorithm is applied to different images, the number of an images which used in the experiments in this paper is three. For all used images, the PSNR value is computed. Finally, the PSNR value of the first stego-image is equal (80.74), while the second stego-image is equal (80.01), and the PSNR value for the third stego-image is (81.5). Generally, the results of paper experiments are good.
