SECURED IMAGE TRANSFORMATION USING DISORGANIZED CHART PATTERN TECHNIQUE

Abstract

An Enhanced disorganized chart pattern based algorithm for image encryption to improve the security of the algorithm.. The basic idea behind the proposed algorithm is to alter the coupling direction used to update the map variables. The altered coupling direction results into a totally different set of initial conditions and map variables of three disorganized chart pattern Based on experiments will show that the enhanced algorithm with chosen coupling direction can encrypts the color digital images. The image which given as input is retrieved as same as the original image while decrypting. Here many distortions take place when the image is converted pixel by pixel, this helps in high secrecy of the encrypted image.
