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. -In this paper, four chaotic maps are compared and noise effects
