In this study, we are doing a cryptography scheme which can modify the visualization of pictures. The image protection is very critical. It does not alter the value of the header and the metadata. We are just trying to modify the color intensities. Every image consists of three color layers. There are red, green and blue (RGB). Each layer has numbers which represent the intensity. RC4 is used to change the color intensity in every layer. The encryption process it to manipulate the integer number and produce the encrypted value. We determine how many layers is going to be encrypted. The fuzziness of the encrypted image depends on how many layer are included. The visualization will be unrecognized after the encryption. It changes to a noisy picture. This method makes the image content secure and undetected.
