Image Encryption using Chaotic Maps and DNA Addition Operation and Noise Effects on it

Abstract

In this paper, four chaotic maps are compared and noise effects are observed on image. Firstly, we use the image encryption algorithm to convert original image to encrypted image. Now we apply noise on the encrypted image and then decrypt cipher image with noise back to original image. The Simulation experimental results shows that Cross Chaotic map has got best results. Also, noise has a little effect on original image and can easily be received by the receiver.
