Abstract
The study present a new technique to image encryption, by partitioning the images to 4*4 and 8*8 blocks, the proposed technique of block replacement introduced by dividing the security key to four segment and one bit from the mod of the segment is selected with it’s complement. The diagonal mappings of the blocks are used to reduce the regularity that can be occur through the blocks mapping process. The wavelet used as a tool to deform the image histogram by converting the histogram of the image to two regions of black and white, in order to remove the information from the image. The last stage of the proposed technique is to apply the Cipher Block Chaining (CBC), which create fictitious information to the image histogram. The correlation of two adjacent pixels is used to measure the degree of image adjacencies. The results showed that the original image have adjacency about 90%, by the proposed technique of the image encryption of the adjacency reduced to about 2%. The new technique applied to different sources and sizes of images and it gave good results.
