چکیده | ||
Due to the increase in the sending of medical, military, financial, etc., the need to use processing and encryption in sending images to ensure the non-abuse transmission is essential. Image encryption has come to the attention of researchers in recent years because of its function in maintaining security and hiding confidential information in images. In this paper, the chaos system was suggested to increase the security of images sent in the network. On the other hand, the proposed method proposed a fast Fourier transform to reduce the processing load using composite images. By combining different parts of the images and encrypting them by chaos and Fourier transform, the original images will not be easily detectable, ensuring the security of the submitted images. The evaluation results showed that in addition to reducing the processing volume and execution time, the security of the composite images was also established by the proposed method. | ||
