Image Symmetric Encryption based on Block Displacement

The main purpose of this work is the management of security. This will allow users authorization and integrity, accuracy and images security circulating on the Internet. Addition to that, more effort is required for an image-based data in the process of encrypting and decrypting the image. Proposed Architecture facilities for encrypting and decrypting an image using the suitable key and is designed to work for the same purpose. In this article we present a strategy for the new permutations based on a combination of different blocks of pixels and the symmetric encryption algorithm newly developed called "Image Symmetric Encryption Based on Block Displacement". The different blocks of the selected image is formed to change the layout of pixels into an image by the interchanging process, and then using the proposed symmetric encryption Algorithm the processed image will be encrypted
