Abstract: With the fast growth in multimedia and network technologies, the image compression and encryption become a very important part in the communication and storage of images. Image compression methods proposed by the authors have no concern of security. Similarly, image encryption methods proposed by the researchers have no concern of image size. This research presents a way to apply image encryption with compression using a secret key. In compression stage, Five Modulus Method (FMM) and FMM protocol apply to each band of image (R, G, B). The encryption stage consists of two-part diffusion and confusion operations. In diffusion part on all the bits of pixels in the image a sequential XOR operation is done and confusion part makes a circular rotate right of these bits. On the other hand, the suggested system uses geffe generator to generate an initial secret key. To evaluate our suggested system number of performance measurements are used like entropy, correlation, histogram, PSNR, MSE, AD, SC, MD, NAE and compression ratio to show the power of the suggested system. The suggested system is implemented in Vb6 language.
