Özet

The main goal of the work in the field of steganography is to transmit data in a cover image with minimal distortion. The proposed method aims to transmit periodically updated data in a highly secure manner through a low-distortion steganographic cover image. Storing these data directly in the cover image poses a major security risk. Therefore, the datas to be transmitted is not directly hidden in the cover image, but in the chaotic pattern image on the server side. In the cover images, the row and column address data of the logical fields of the chaotic pattern image are hidden. Thus, a small amount of data representing a large amount of data is sent to the receiver along with the cover object. Since the representative data is much smaller than the data to be transmitted, the distortion of the cover image is minimized. The method also includes reverse social engineering. In this application, attackers are misled to distinguish between the hidden data and the real data. PSNR metric is used to compare the method with other studies. Only the blue channel of the Baboon, Barbara and Lena cover images was loaded with data. In this case, the PSNR value in the red and green channels was infinite. The PSNR result in the blue channel is also higher than the methods used in other studies. The high results indicate that the distortion in the cover images is lower.
