Abstract

Due to the rise in the use of internet facility for data/information transmission, the data must be kept secured. The data to be transferred can also be an images. So that images being transmitted through the internet must also be kept much secured for gaining the trust from the users. The image encryption can be performed through many ways. The proposed method of image encryption is by mapping with the chaotic maps provided as chaos theory. The original image will be divided in to different blocks, then permute and diffuse separately at the pixel level of each block. Finally combine and diffuse the permuted image as a cipher image. The proposed method also experimented and tested to reach the current need of image encryption to maintain the security among the users.
